Full textAbstract:
A collection of rare, mainly deep-sea species of chitons collected from South Australia, Tasmania and Heard Island has been processed. In the materials there was a second find of Belknapchiton opiparus, which made it possible to significantly supplement the previous descriptions of this species. For the first time, species of genus Stenosemus have been found for Australia and Macquarie Island. Two new species (Leptochiton australis n. sp. and Belknapchiton gowlettholmesae n. sp.) have been described. A high degree of endemism of the faunas of chitons of the family Leptochitonidae of Australia and New Zealand has been confirmed.

Full textAbstract:
This article is devoted to the study of the systematic, biomorphological, and ecological classifications of the dendroflora of eleven park-monuments of landscape art established in the second half of the 20th century in the Ukrainian Polissya. In the protected parks, we identified 193 taxa of woody plants that belong to 82 genera and 34 families. The most common one was the family Rosaceae Juss. Among encountered woody plants, 14.2% species were indigenous and occurred in 5-11 parks. Fifty-nine woody plant species, among which 64.4% were rare, were associated with a single park and were represented by 1-7 specimens. At the same time, 69 woody plant species were associated with 2-4 parks, with 40.4% rare and 17.4% indigenous plant species. Life forms were represented by phanerophytes (36, 63, and 76 species of megaphanerophytes, mesophanerophytes, and micro- and nanophanerophytes, respectively) and a chamaephyte. In turn, the ecological structure was dominated by mesophytes (39.8%), hemisciophytes (46.6%), and mesotrophs (51.7%). Except for Bairak PMLA and Novostavskyi dendropark, the dendroflora of the surveyed parks was diverse.

Full textAbstract:
The article describes the patterns and features of the development of the musical art of Dagestan at different stages of its evolution over more than half a century of history. We have analyzed the components of the musical and professional tradition, giving a holistic view of it, versatile reflecting both the originality and originality, and historical variability. These include: genre-species differentiation and systemic connections, stylistics and means of musical expression.The multifaceted study and the possibility of interpreting the data obtained allows one to create an idea of the ways of the formation and development of the musical art of Dagestan during the period under consideration. The initial premises of the study can be summarized as follows.The structure of musical art is formed on the basis of the interrelationships of composer's creativity, performing practice and various cultural interchanges that undergo stylistic and genre-specific changes.The second premise was the look at the musical art of Dagestan as an actual part of modern culture. Therefore, the main source has become various forms of broadcasting musical culture (listening practice and analytical observations at concerts of classical music).Reliance on contemporary musical material and direct observation of the musical process in the field of classical, pop and other spheres of culture presupposes the study of the phenomenon in a synchronic aspect. The presence of publications by different authors and our own research experience make it possible to a certain extent to make diachronic comparisons.The important regularities in the development of the Dagestan academic musical art identified by us can form the basis for further research of genre phenomena in different historical periods.

Full textAbstract:
AbstractThe helminth fauna of weatherfish (Misgurnus fossilis) in natural range is reviewed. Several helminth species reported in weatherfish are discussed with reference to host specificity and their geographical distribution. The current list of helminth parasites of the weatherfish includes 37 species. Most (15) are digenean trematodes, half of them being larval stages. Only one species of trematode — Allocreadium transversale is more specific parasite of weatherfish. Second largest group are Monogenea, with 10 species. Two of them (Gyrodactylus strelkovi and G. misgurni) are found only in the genus Misgurnus. Tapeworms (6 species) and Nematodes (6 species) are less numerous. No Acanthocephala, however, were ever found.

Now a days every mankind is suffering due to infections. Ayurveda, the science of life helped to take preventive measures which boost our immunity. It is plant-based science. Many medicinal plants found useful in daily life of common people for boosting immunity. Identifying the plant species having medicinal plant is challenging, it requires botanical expert. In the process of manual identification, botanical experts use various plant features as the identification keys, which are examined adaptively and progressively to identify plant species. The shortage of experts and trained taxonomist created global taxonomic impediment problem which is one of the major challenges. Various researchers have worked in the field of automatic classification of plants since the last decade. The leaf is considered as primary input as it is available throughout the whole year. The research paper mainly focuses on the study of transfer learning approach for medicinal plant classification, which reuse already developed model at the starting point for model on a second task. Transfer learning approach is a black box approach used for image classification and many more applications by extracting features from an image. Some of the transfer learning models are MobileNet-V1, VGG-19, ResNet-50, VGG-16. Here it uses Mendeley dataset of Indian medicinal plant species which is freely available. Output layer classifies the species of leaves. The result provides evaluation and variations of above listed features extracted models. MobileNetV1 achieves maximum accuracy of 98%.

Acinetobacter are gram negative coccobacilli and ubiquitous in nature1. Quiet frequently they are recovered from inpatients who are hospitalized for prolonged illness and often multiple times. Although originally considered to be a low grade opportunistic pathogen Acinetobacter species has emerged to be one of the common nosocomial pathogen. These isolates are often MDR1. It still remains a physician’s dilemma whether to treat or not such isolates, considering them pathological or commmensals. In one of our case it was isolated as a commensal and the patient did not require any antibiotic. On the hand the second case succumbed just after we started the susceptible antibiotic.

Full textAbstract:
The art of visionaries and outsiders is a space of fantastic narratives, authorial mythologies, and hybrid identities. Their personal religious doctrines and pseudohistorical epics generate monstrous bodies and entities combined with characteristics of the divine, human, and machine. The article examines the representations of monstrosity in visionary and outsider art, art brut, and art of the insane of the 20th and early 21st centuries, investigating the representations of monsters in the artworks of Karl Brendel (Karl Genzel), Bernard Schatz (L-15), and Allen Christian. The general characteristics of monstrosity in visionary and outsider art of the 20th and early 21st centuries are the visionary nature of images, multiculturalism, hybridity, the combination of the scientific, pseudoscientific and religious narratives and popular culture. In the early 20th century, religion had a significant impact, manifested in the hybridization of religious images and pseudo-anthropomorphic distortion in art. In the second half of the 20th century, space narratives had a great influence and were embodied in images of aliens, the cosmos, etc. The turn of the 20th and 21st centuries was the time for rethinking technology, and the symbiosis of human and technology, the origin of species and alternative theories of evolution became popular themes.

Context. Helium, the second most abundant element in the Universe, with a relative abundance of He/H ~ 1/10, has never been observed in any other form than that of a neutral atom (He) or an ion (He+) in the interstellar medium. Since He is a noble gas its non-observation as part of neutral molecular systems is understandable, but it is very surprising for a positively charged species such as HeH+ that is a stable diatomic ion whose spectral signatures are well known in the laboratory. Aims. This non-observation, even in hydrogen rich regions, could imply that HeH+ is not a proper target and that alternatives have to be considered, such as small HeHn+ clusters. The present study aims at finding whether the leading term HeH3+ fulfills the conditions required. Methods. We addressed the question with state-of-the-art numerical simulations. We determined a two-dimension ab initio potential energy surface (PES) of the HeH3+ cluster along the He...H3+ and HeH+...H2 reaction coordinates. The calculations rely on complete active space configuration interaction followed by a second order perturbation treatment (CAS-PT2). This surface was used for the evaluation of the two radiative associations rate constants by means of a quantum treatment of the collision between the interacting fragments. Results. These calculations show unambiguously that HeH3+ is the most stable point on the corresponding global PES. Then, we determined the rate constants of the radiative associations HeH+ + H2 and He + H3+ leading to HeH3+. Conclusions. Significative values were obtained that reach up to 2 × 10-18 cm3 s-1, which should stimulate new tentatives to detect molecular helium in astrophysical objects.

Full textAbstract:
Neutral intervals between minor and major intervals have been used in Persian/Iranian art music for centuries or even millennia. During the medieval era in the Muslim world, several scholars proposed ratios for the various intervals used in their recognized musical species and presented systematized parent scales. However, this did not result in unanimously accepted or standardized neutral interval sizes or fretting systems in practice, either in the past or in modern times. This article examines neutral intervals and parent scales in Persian art music in four sections. First, the neutral intervals according to the main medieval theorists of the Muslim world (specifically, from the eighth through the fifteenth centuries) are reviewed. Second, the opinions of several twentieth-century mu sicologists and their measured/proposed neutral intervals are critically examined. Third, several ratios for neutral seconds are considered based on different theoretical approach es, and a unique ratio, close to the current practice, is proposed. Finally, the arithmetic mean calculation method is directly applied to an 18-tone scale (for the fretting of a Persian tār/sitār) as an example of a standardized parent scale.

Full textAbstract:
Thesis (MA)--Stellenbosch University, 2015.ENGLISH ABSTRACT: This thesis aims to examine to what extent the visual representations of ancient Mesopotamia portrayed the royal ideology that was present during the time of their intended display. The iconographic method is used in this study and this allows for a better understanding of the meaning behind the work of art. This method allows the study to better attempt to comprehend the underlying ideology of the work of art. The eight images studied date between three thousand BCE and one thousand BCE and this provides a broad base for the study. By having such a broad base it enables the study to provide a brief understanding of how the ideology adapted over two thousand years. The broad base also enables the study to examine a variety of different gestures that are portrayed on the representations. This thereby provides the reader with a better understanding of why certain gestures were used and how the underlying ideology was communicated through these movements. The study concludes that while the gestures lend a life-like appearance to the representation they do not solely portray an underlying ideological message. Rather, they enhance the already inherent ideological message.
AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek tot watter mate die visuele voorstellings van Ou Mesopotamië die koninklike ideologie — van die tyd toe hulle uitgestal is — uitgebeeld het. Die ikonografiese metode is in hierdie studie gebruik en maak dit moontlik om 'n beter begrip van die betekenis agter die kunswerk te verkry. Die metode stel die studie in staat om die onderliggende ideologie van die kunswerk beter te verstaan. Die agt bestudeerde beelde dateer tussen drieduisend v.C. en 'n duisend v.C. en bied 'n breë basis vir die studie. So ‘n breë basis stel die studie in staat om te verstaan hoe die ideologie oor meer as twee duisend jaar aangepas is. Die breë basis stel die studie ook in staat om 'n verskeidenheid verskillende gebare wat uitgebeeld word, te ondersoek. Hierdeur verskaf dit die leser met 'n beter begrip waarom sekere gebare gebruik is en hoe die onderliggende ideologie deur middel van hierdie bewegings gekommunikeer is. Die studie kom tot die gevolgtrekking dat terwyl die gebare 'n lewensgetroue voorkoms aan die voorstelling gee, hulle nie uitsluitlik onderliggende ideologiese boodskappe uitbeeld nie. Inteendeel, hulle versterk die reeds onderliggende ideologiese boodskap.

Cette étude s'est focalisée sur deux axes principaux : la caractérisation et l'étude des propriétés des substances extractibles de deux essences secondaires de la forêt gabonaise en vue d'une valorisation éventuelle, Letestua durissima et Petersianthus macrocarpus, ainsi que l'analyse des facteurs influençant la durabilité naturelle du bois. Les recherches ont débuté par des extractions successives par macération et au Soxhlet (utilisant le cyclohexane, le dichlorométhane, l'acétone, le mélange toluène/éthanol et l'eau) l'écorce, l'aubier et du duramen. Les résultats ont révélé des concentrations élevées de substances extractibles, notamment dans les écorces des deux essences, avec une analyse phytochimique mettant en évidence la présence de diverses familles chimiques telles que des composés phénoliques, des acides gras, des terpènes et des terpénoïdes. Les analyses infrarouges ont confirmé la présence de ces composés. De plus, l'utilisation de la GC-MS et de la LC-MS nous a permis d'identifier des composés tels que la catéchine, la gallocatéchine, l'acide gallique, la vanilline, etc. Les extraits ont démontré des propriétés antifongiques prometteuses contre les champignons de pourriture brune et blanche, ainsi qu'une activité antibactérienne, notamment contre Escherichia coli, avec les extraits de Letestua durissima se démarquant particulièrement. Les extraits ont également montré des propriétés anti-termites intéressent. Enfin, une étude plus large concernant l'étude de différents facteurs influençant la durabilité naturelle du bois a mis en évidence une forte corrélation entre des paramètres tels que la densité, le taux d'humidité, la mouillabilité, le taux d'extraits et le rapport sucre/lignine et la durabilitéThis study focused on two main axes : the characterization and study of the properties of extractable substances from two secondary species of the Gabonese forest with a view to possible valorization, Letestua durissima and Petersianthus macrocarpus, as well as the analysis of the factors influencing the natural durability of wood. The research began with successive extractions by maceration and Soxhlet (using cyclohexane, dichloromethane, acetone, toluene/ethanol mixture and water) of the bark, sapwood and heartwood. The results revealed high concentrations of extractables, particularly in the barks of both species, with phytochemical analysis highlighting the presence of various chemical families such as phenolic compounds, fatty acids, terpenes and terpenoids. Infrared analyzes confirmed the presence of these compounds. Additionally, the use of GC-MS and LC-MS allowed us to identify compounds such as catechin, gallocatechin, gallic acid, vanillin, etc. promising against brown and white rot fungi, as well as antibacterial activity, particularly against Escherichia coli, with Letestua durissima extracts particularly standing out. The extracts also showed anti-termite properties. Finally, a broader study concerning the study of different factors influencing the natural durability of wood highlighted a strong correlation between parameters such as density, humidity rate, wettability, extract rate and sugar/lignin ratio and sustainability

Full textAbstract:
This study explores the relationship between language learning strategies and learner variables of Sri Lankan learners of English as a Second Language (ESL) with special reference to their personality types to examine what implications these associations have for the teaching of ESL in the Sri Lankan sociocultural context. In order to investigate the above, a large and representative sample of the ESL population was chosen. The sample taken for analysis comprised 886 subjects from six secondary schools which operate under the Ministry of Education in the Sri Lankan government. These subjects belonged to three distinct subcultures as demarcated by their first language (L1), Religion and Ethnicity in Sri Lanka. Data were collected using two questionnaires - a language learning strategy inventory and a personality assessment questionnaire, between April 2002 and June 2002 in Sri Lanka. Two statistical tests were used to measure the associations between the learner variables and language learning strategies: Multivariate Analysis of Variance (MANOVA) and Univariate Analysis of Variance (ANOVA). The findings show differences in strategy use or rather the ways the three groups learn the target language indicating that these strategy choices are closely correlated to their personality type, gender and religion/ethnicity. The findings also indicate that these variables affect the strategy choices both as collective and individual forces and when working as collective forces there is a complex interplay between these variables. While this study clearly demonstrates the association between learner variables and language learning strategies, it acknowledges the possible dangers in discussing these associations in cross-cultural comparisons. It also suggests the need for more ethnographic research to further elucidate the findings obtained in the current study. Based on these findings in the current study, this thesis strongly argues that ELT pedagogy cannot be independent of the Sri Lankan sociocultural context. It is therefore strongly suggested that ELT pedagogies should: (1) develop within the socio -cultural contexts of the learners; (2) be orientated to the culture of speakers of a Sri Lankan variety of English; (3) incorporate teaching material based on rhetoric indigenous to their culture. The study also shows the complexities of ESL instruction in the Sri Lankan socio-cultural context where its history, different cultures, first languages, ethnicities and religions all make a significant contribution to the learning/teaching of the target language. The challenge for teaching ESL in Sri Lanka is even higher given that all languages come with their own cultural, historical and ethnic trappings.

Full textAbstract:
La present tesi doctoral s’ha centrat en el repte d’aconseguir, mitjançant Fabricació Additiva (FA), models per a assaig quirúrgic, sota la premissa que els equips per fer-los haurien de ser accessibles a l’àmbit hospitalari. L’objectiu és facilitar l’extensió de l’ús dels prototips com a eina de preparació d’operacions quirúrgiques, transformant la pràctica mèdica actual de la mateixa manera que en el seu moment ho van fer tecnologies com les que van facilitar l’ús de radiografies. El motiu d’utilitzar FA, en lloc de tecnologies més tradicionals, és la seva capacitat de materialitzar de forma directa les dades digitals obtingudes de l’anatomia del pacient mitjançant sistemes d’escanejat tridimensional, fent possible l’obtenció de models personalitzats. Els resultats es centren en la generació de nou coneixement sobre com aconseguir equipaments d’impressió 3D multimaterials accessibles que permetin l’obtenció de models mimètics respecte als teixits vius. Per facilitar aquesta buscada extensió de la tecnologia, s’ha focalitzat en les tecnologies de codi obert com la Fabricació per Filament Fos (FFF) i similars basades en líquids catalitzables. La recerca s’alinea dins l’activitat de desenvolupament de la FA al CIM UPC, i en aquest àmbit concret amb la col·laboració amb l’Hospital Sant Joan de Déu de Barcelona (HSJD). El primer bloc de la tesi inclou la descripció de l’estat de l’art, detallant les tecnologies existents i la seva aplicació a l’entorn mèdic. S’han establert per primer cop unes bases de caracterització dels teixits vius -sobretot tous- per donar suport a la selecció de materials que els puguin mimetitzar en un procés de FA, a efectes de millorar l’experiència d’assaig dels cirurgians. El caràcter rígid dels materials majoritàriament usats en impressió 3D els fa poc útils per simular tumors i altres referències anatòmiques. De forma successiva, es tracten paràmetres com la densitat, la viscoelasticitat, la caracterització dels materials tous a la indústria, l’estudi del mòdul elàstic de teixits tous i vasos, la duresa d’aquests, i requeriments com l’esterilització dels models. El segon bloc comença explorant la impressió 3D mitjançant FFF. Es classifiquen les variants del procés des del punt de vista de la multimaterialitat, essencial per fer models d’assaig quirúrgic, diferenciant entre solucions multibroquet i de barreja al capçal. S’ha inclòs l’estudi de materials (filaments i líquids) que serien més útils per mimetitzar teixits tous. Es constata com en els líquids, en comparació amb els filaments, la complexitat del treball en processos de FA és més elevada, i es determinen formes d’imprimir materials molt tous. Per acabar, s’exposen sis casos reals de col·laboració amb l’HJSD, una selecció d’aquells en els que el doctorand ha intervingut en els darrers anys. L’origen es troba en la dificultat de l’abordatge d’operacions de resecció de tumors infantils com el neuroblastoma, i a la iniciativa del Dr. Lucas Krauel. Finalment, el Bloc 3 té per objecte explorar nombrosos conceptes (fins a 8), activitat completada al llarg dels darrers cinc anys amb el suport dels mitjans del CIM UPC i de l’activitat associada a treballs finals d’estudis d’estudiants de la UPC, arribant-se a materialitzar equipaments experimentals per validar-los. La recerca ampla i sistemàtica al respecte fa que s’estigui més a prop de disposar d’una solució d’impressió 3D multimaterial de sobretaula. Es determina que la millor via de progrés és la de disposar d’una pluralitat de capçals independents a fi de capacitar la impressora 3D per integrar diversos conceptes estudiats, materialitzant-se una possible solució. Cloent la tesi, es planteja com seria un equipament d’impressió 3D per a models d’assaig quirúrgic, a fi de servir de base per a futurs desenvolupaments.La presente tesis doctoral se ha centrado en el reto de conseguir, mediante Fabricación Aditiva (FA), modelos para ensayo quirúrgico, bajo la premisa que los equipos para obtenerlos tendrían que ser accesibles al ámbito hospitalario. El objetivo es facilitar la extensión del uso de modelos como herramienta de preparación de operaciones quirúrgicas, transformando la práctica médica actual de la misma manera que, en su momento, lo hicieron tecnologías como las que facilitaron el uso de radiografías.

De forma sucesiva, se tratan parámetros como la densidad, la viscoelasticidad, la caracterización de materiales blandos en la industria, el estudio del módulo elástico de tejidos blandos y vasos, la dureza de los mismos, y requerimientos como la esterilización de los modelos. El segundo bloque empieza explorando la impresión 3D mediante FFF. Se clasifican las variantes del proceso desde el punto de vista de la multimaterialidad, esencial para hacer modelos de ensayo quirúrgico, diferenciando entre soluciones multiboquilla y de mezcla en el cabezal. Se ha incluido el estudio de materiales (filamentos y líquidos) que serían más útiles para mimetizar tejidos blandos.

Finalmente, el Bloque 3 desarrolla numerosos conceptos (hasta 8), actividad completada a lo largo de los últimos cinco años con el apoyo de los medios del CIM UPC y de la actividad asociada a trabajos finales de estudios de estudiantes de la UPC, llegándose a materializar equipamientos experimentales para validarlos. La investigación amplia y sistemática al respecto hace que se esté más cerca de disponer de una solución de impresión 3D multimaterial de sobremesa. Se determina que la mejor vía de progreso es la de disponer de una pluralidad de cabezales independientes, a fin de capacitar la impresora 3D para integrar diversos conceptos estudiados, materializándose una posible solución. Para cerrar la tesis, se plantea cómo sería un equipamiento de impresión 3D para modelos de ensayo quirúrgico, a fin de servir de base para futuros desarrollos.

AbstractThis chapter highlights the research and efforts that have been done to understand the composition of the genome and the mechanisms underlying the genetic inheritance in sweetpotato, with focus on the cultivated hexaploid sweetpotato. The first part of the chapter focuses on dissecting strategies and methods that have been used to study and understand key factors that affect the genetic behavior in polyploid species, with emphasis on linkage analysis, highlighting the most common types of experimental populations used for genetic mapping, the obtention of genotype information, and the choice of analytical methods to study such populations. The second part of the chapter dives deeper into the knowledge accumulated through the application of traditional methods and the more recent adoption of cutting-edge technologies, combined with state-of-the-art algorithms that were developed specifically for polyploid species, to study and shed a light on the genetic architecture and the mechanisms that drive the genetic transmission in the cultivated hexaploid sweetpotato.

AbstractUnderstanding tree and stand growth dynamics in the frame of climate change calls for large-scale analyses. For analysing growth patterns in mountain forests across Europe, the CLIMO consortium compiled a network of observational plots across European mountain regions. Here, we describe the design and efficacy of this network of plots in monospecific European beech and mixed-species stands of Norway spruce, European beech, and silver fir.First, we sketch the state of the art of existing monitoring and observational approaches for assessing the growth of mountain forests. Second, we introduce the design, measurement protocols, as well as site and stand characteristics, and we stress the innovation of the newly compiled network. Third, we give an overview of the growth and yield data at stand and tree level, sketch the growth characteristics along elevation gradients, and introduce the methods of statistical evaluation. Fourth, we report additional measurements of soil, genetic resources, and climate smartness indicators and criteria, which were available for statistical evaluation and testing hypotheses. Fifth, we present the ESFONET (European Smart Forest Network) approach of data and knowledge dissemination. The discussion is focussed on the novelty and relevance of the database, its potential for monitoring, understanding and management of mountain forests toward climate smartness, and the requirements for future assessments and inventories.In this chapter, we describe the design and efficacy of this network of plots in monospecific European beech and mixed-species stands of Norway spruce, European beech, and silver fir. We present how to acquire and evaluate data from individual trees and the whole stand to quantify and understand the growth of mountain forests in Europe under climate change. It will provide concepts, models, and practical hints for analogous trans-geographic projects that may be based on the existing and newly recorded data on forests.

AbstractThis chapter will consider the noteworthy changes in Japan’s peacekeeping policy under the second Abe administration (2012–2020), with special emphasis on the period between 2013 and 2017. Since its outset in the early 1990s, Japan’s peacekeeping policy had been gradually shaped by the trends of “integration” and the “robustness” in United Nations Peacekeeping Operations (UNPKOs), but various problems remained unsolved, especially in terms of “robustness.” With the return of Prime Minister Abe at the end of 2012, reforms to follow the trend of “robustness” were carried out as part of his all-inclusive renovation of Japan’s security policy, namely the Peace and Security Legislation, to resolve numerous long-standing problems in the field. With this in mind, this chapter starts by considering new developments in Japan’s security policy as a whole before examining how these sweeping reforms transformed the quality of Japan’s peacekeeping, paying special attention to the newly added roles, such as the “coming-to-aid” duty. This chapter will also trace moves toward “integration,” especially regarding the “All Japan” approach.

AbstractThe human species is biologically distinguished by low fertility. In fact, with each menstrual cycle, a couple at the peak of their reproductive capacity has only about a 30% chance of conceiving. The WHO states infertility as “a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected intercourse.”Assisted reproductive technology (ART) consists of all treatments or procedures that include the in vitro handling of both human oocytes and sperm or of embryos, for the purpose of establishing a pregnancy.The techniques are usually divided into three broad categories: First level techniques: Intrauterine and Intracervical Insemination (IUI/ICI), the simpler and less invasive ones, such as intrauterine insemination (IUI) with or without Intracervical Insemination (ICI) ovarian stimulation. Second level techniques: the more complex and more invasive ones that can be performed under local anesthesia or deep sedation, which differ from the basic techniques as they involve manipulation of female and male gametes and because they require in vitro fertilization. Among these techniques the IVF (In Vitro Fertilization and Embryo Transfer), ICSI (Intracytoplasmic Sperm Injection), and the possible cryopreservation of male and female gametes and embryos. Third level techniques procedures that require general anesthesia with intubation, including: laparoscopic egg retrieval, intra-tubal transfer of male and female gametes (GIFT), zygotes (ZIFT) and /or embryos (TET) laparoscopically; microsurgical sampling of gametes from the testicle: Testicular Sperm Extraction (TESE), Microsurgical Testicular Sperm Extraction (microTESE), Testicular Sperm Aspiration (TESA); microsurgical sampling of gametes from the epididymides: Percutaneous Epididymal Sperm Aspiration (PESA) and Microsurgical Epididymal Sperm Aspiration (MESA). In all assisted reproduction techniques, the seminal fluid receives a treatment able to induce capacitation “in vitro” so that the activated spermatozoa, at the threshold of the acrosomal reaction, can interact with the mature oocytes. Preimplantation Genetic Screening (PGS) and Preimplantation Genetic Diagnosis (PGD) are highly specialized procedures which involve removing three to four cells from a 5–6 day old blastocyst and testing them for chromosomal abnormalities prior to transferring the embryo into a woman’s uterus. According to data reported from the European IVF-Monitoring Consortium (EIM) for the European Society of Human Reproduction and Embryology (ESHRE), the clinical pregnancy rates (PR) per aspiration and per transfer are 28.0% and 34.8%, respectively. After ICSI, the corresponding rates are 24% and 33.5%. ART can alleviate the burden of infertility on individuals and families, but it can also present challenges to public health as evidenced by the high rates of multiple delivery, preterm delivery, and low birth-weight delivery experienced with ART.

Full textAbstract:
Together with the discrete but unquestionable presence of carnivore taphonomic marks on large mammal bones (diaphysis cylinders, gnawing and digestion marks), the 35 PPNA dog bones from Klimonas are the earliest evidence of the presence of the species in Cyprus. Osteometric data, especially on a sub-complete hemi-mandible, indicate that these dogs were indistinguishable from PPNA dogs on the continent. The low frequency of dogs (0.5%) is in accordance with most continental PPNA sites. Nearly 90% of the dog bones were found in special places relating to the first and second phases of the Communal building (entrance, earth floor, benches). This specific spatial distribution denotes the special processing of dog remains after their death. Parallels with the processing of deceased human bodies is discussed, as well as the possible psychopomp value of dogs. In addition to this symbolic use, dogs were also used as a food resource, as cleaners of the village through scavenging and probably for hunting wild boars.

Full textAbstract:
Mosaics containing detailed representations of different fish species were produced in large numbers in many parts of the Roman world. This chapter focuses on a handful of the earliest and most technically accomplished examples: the fish mosaics laid in Praeneste and Pompeii during the late second and early first centuries BC. These compositions exhibit striking iconographic similarities, inviting reflections on how they were designed and made. Having reconstructed a possible chaîne opératoire, the discussion then turns to how the mosaics were understood by contemporary viewers. It is argued that the compositions should be connected to the interest in fish and seafood that flourished in Italy during the Late Republican period, but that they may have drawn inspiration from earlier fashions in the Hellenistic East.

Abstract Minerals, naturally formed inorganic chemical elements and compounds, are created by diverse geological processes and, under favorable conditions, form exquisite crystals and striking assemblages within the rocks of the Earth. These are collectors’ pieces. Traditionally, mineral specimens are products or by-products of mining and quarrying industries, so supply is governed as much by economic climate, consumer demand, and political factors as by the intrinsic rarity or otherwise of a particular mineral species. A market exists for aesthetically fine and rare “natural” mineral specimens, both newly extracted from the earth and passed on second hand, perhaps from previous collections of note. It is largely the preserve of enthusiasts and more recently investors and, like that of the art world, the market is international in scope, featuring specialist dealers, connoisseur collectors, large sums of money, auctions, museum exhibitions, and forgeries. This chapter looks at the interfaces between scientists, mineral collectors, and curators.

Abstract Imagine an internationally renowned museum, housing priceless objects, that does not know what they are, or in which rooms most of them are stored, has no acquisition strategy, and only a ramshackled and makeshift restoration and conservation programme. It is, of course, unthinkable! Unthinkable at least in the world of art, but not in the natural world. It is a disgrace that we still have only the haziest notion of how many species there are on earth, how they are distributed, and how to ensure the survival of most of them into the twenty-second century and beyond, in the face of relentless and rapidly expanding human pressures.

Abstract The first of the two questions in the title of this chapter was set aside back in chapter 6 simply to avoid whatever existential presumptions might arise in trying to find an answer. As we return to it, we should keep in mind two things. The first is that, whatever else species are, they appear in our language as categories of organisms. The second is that, a Part from the pleasantry of a short phrase, there is no need for a terse definition of the word species. Whatever real species are we can take our time to describe the reasons they exist and those things that different species share. Biologists’ demand for a definition that cuts cleanly through species uncertainty may be understandable given the awkwardness of all that uncertainty; but as a hopeful mechanism for ridding ourselves of the species problem, it is misplaced. Quite simply, we cannot presume to describe things as having more distinction than actually occurs in nature.

Full textAbstract:
<em>Abstract</em>.-Tagging fish with electronic tags can provide information on movement, migration, behavior, and stock structure while diadromous species are at sea. The state of the art technology for tracking fishes in the marine environment includes two families of tags. Archival tags store data and either relay them to satellites or require recapture for interrogation. Low return rates for diadromous species make these tags very expensive to use. A second type, acoustic tags, sends signals to passive receivers. Information is collected from the fish only when it is within range of a receiver. Technology is now being developed to mesh these tags into a fully integrated tag that will permit archived data to be transmitted acoustically over multiple frequencies to receivers allowing data retrieval without recapturing the animal. The new technology includes a "business card" tag that is a miniaturized receiver coupled with a coded pulse transmitter. These tags will exchange and record individual-specific codes when two animals carrying them come within acoustic range of each other, which will allow data from many animals to be moved ashore through few animals. These devices would be ideal for quantifying the degree of school fidelity (or, conversely, mixing) or the degree of at sea interaction of fishes from different river systems and provide ecological information to enhance management in an ecosystem approach to fisheries.

Full textAbstract:
The ability to analyze surface elemental composition has existed for some time. The various methods include Auger Electron Spectroscopy (AES), Secondary Ion Mass Spectrometry (SIMS), and many more.1 However, molecular surface analysis is only now achieving the same sensitivity and selectivity. Molecular surface analysis often utilizes various optical probes: IR Reflection Absorption Spectroscopy, Sum-Frequency (or Second Harmonic) Generation Spectroscopy on Surfaces, etc. These techniques are generally lacking species-specific information. Another approach is to remove the molecule from the surface and probe it in the gas phase, e.g., with state- of-the-art mass spectrometry. Since mass spectrometry offers high resolution and high sensitivity, the remaining problems are removal of the molecule from the surface and ionization without alteration of the molecule (e.g., fragmentation). These pose serious complications for large molecules, in particular. Furthermore, if the molecule of interest is only a minor constituent of a sample, mass resolution and sensitivity are not sufficient for species identification, and a pre- selection in the ionization is often necessary. Our solution is to employ lasers for both desorption from the sample and ionization (post-ionization) of the gas-phase species. The ability to choose the wavelength and intensity of the desorption laser and the post-ionization laser allows for proper tailoring to the needs of the investigation. This will be demonstrated with two examples. First, a vulcanizate (rubber) will be analyzed with a time-of-flight mass spectrometer for the organic additives present in minor concentrations in the near-surface region. Second, a new class of carbon molecules (fullerenes) will be examined with a Fourier transform mass spectrometer.

Cyprinids as the second intermediate host are a source of infection of the definitive host
with zoonotic trematode infections. Currently in some regions of European Russia,
opisthorchiasis is constantly recorded in humans. This relates to the Lipetsk Region,
where the species diversity and distribution of opisthorchides, ecological biological
and epizootological aspects of the circulation of opisthorchidosis remain unstudied.
The materials were collected in 2021-2022 in the south-eastern part of the Lipetsk
Region on the Usman River. We studied 179 specimens of 4 Cyprinid species: the
roach (97 specimens), the bleak (41 specimens), the silver bream (21 specimens) and the rudd (20 specimens). The highest infection rates were observed for opisthorchide
metacercariae (Opisthorchis felineus, Pseudamphistomum truncatum, Metorchis bilis
and Metorchis xanthosomus) with the infection prevalence (IP) of 78.2%; the second
position was occupied by Posthodiplostomum cuticola with the IP 63.7%; they were
followed by Paracoenogonimus ovatus with similar parameters with the IP 21.8% and
Metorchis xanthosomus with the IP 19.6%. According to the results of our research, 6
species of trematode metacercariae including 3 opisthorchide species (O. felineus, P.
truncatum, M. bilis) of epidemiological significance were recorded for the first time
in cyprinid fish in the Lipetsk Region. For all metacercariae species, the current
parameters of infection in cyprinids were revealed.

Tracking individuals is a vital part of many experiments conducted to understand collective behaviour. Ants are the paradigmatic model system for such experiments but their lack of individually distinguishing visual features and their high colony densities make it extremely difficult to perform reliable racking automatically. Additionally, the wide diversity of their species' appearances makes a generalized approach even harder. In this paper, we propose a data-driven multi-object tracker that, for the first time, employs domain adaptation to achieve the required generalisation. This approach is built upon a joint-detection-and-tracking framework that is extended by a set of domain discriminator modules integrating an adversarial training strategy in addition to the tracking loss. In addition to this novel domain-adaptive tracking framework, we present a new dataset and a benchmark for the ant tracking problem. The dataset contains 57 video sequences with full trajectory annotation, including 30k frames captured from two different ant species moving on different background patterns. It comprises 33 and 24 sequences for source and target domains, respectively. We compare our proposed framework against other domain-adaptive and non-domain-adaptive multi-object tracking baselines using this dataset and show that incorporating domain adaptation at multiple levels of the tracking pipeline yields significant improvements. The code and the dataset are available at https://github.com/chamathabeysinghe/da-tracker.

Half a year ago, the Croatian Chamber of Economy and the Croatian Employer’s Association issued the Special Usances in Construction, which regulate the legal relationship between the client (employer) and the contractor. This continues a long tradition of codifying the commercial usages into usances (uzance). It was, however, never sufficiently explored whether the commercial usages can at all be codified. Even if the answer is affirmative, it was not sufficiently explored whether the usances indeed reflect the existing commercial usages. The aim of this research paper is to bridge such gap by analysing the nature of usances and, in particular, the Special Usances in Construction. Several methods are used. First, the textual analysis of the usances. Second, the analysis of jurisprudence. Third, historical method, which explores the origin of usances in former Yugoslavia. The analysis leads to the conclusion that neither earlier usances nor the Special Usances in Construction reflect the existing commercial usages. Instead, they imitate statutory provisions, e.g. by containing the date of the entry into force and even (purportedly) mandatory provisions. Consequently, the Special Usances in Construction have to be qualified as a quasi-legislative instrument. Considering that the legislative power cannot be delegated, unless the parties agree on their application, the Special Usances in Construction cannot be used as a source of law.

Full textAbstract:
The introduction of a histological method into practice of species diagnostics of trematodes of the suborder Paramphistomata Skrjabin et Schulz, 1937, contributed to regular reports on the discovery of new trematode species in the family Paramphistomidae Fischoeder, 1901. At the same time, several new species were described based on identification of specific histological morphological characteristics which in fact turned out to be artifacts in subsequent detailed analysis. Based on this argument, paramphistomid species described in domestic literature sources, namely, Cotylophoron skrjabini, Cotylophoron vigisi, Ceylonocotyle petrowi, Liorchis hiberniae and Liorchis scotiae are considered as invalid. The cause of morphological artifacts on histological sections of paramphistomids are firstly non–standardized or incorrect primary treatment with fixing chemical agents of parasite isolates detected during necropsy in definitive hosts; secondly, errors in the implementation of general histological technique elements which in the applied approach are critically important and require the development of methodologic modernization adapted to work with biological objects with morphological traits; thirdly, incorrect subjective perception of histological artifacts, their false acceptance as distinctive species characters that have diagnostic value in taxonomy of the family representatives. It is necessary to develop optimized methodological techniques adapted to the applied purpose of teaching methods based on general histological technology elements the implementation of which will help to avoid morphological artifacts on histological sections of paramphistomids.

Full textAbstract:
It is important in engineering to elucidate the mechanism of a chemical reaction in turbulent flow. But there are still few studies on reacting turbulent flow in a liquid phase. In this study, the two-dimensional liquid jet with the second-order reaction (A+B←R) is investigated. The concentrations of the species R and the conserved scalar (which is the concentration of other species independent of the above chemical reaction) are measured simultaneously by the optical fiber probe based on light absorbtion spectroscopic method. The concentrations of species A and B are obtained from the conserved scalar theory. Regarding the velocity field, the streamwise velocity is measured by the hot-film anemometer. The moment closure methods are often used for the prediction of turbulent flow. But it is difficult to apply it to the reacting turbulent flow because of the high non-linearity of the reaction rate terms. It is commonly known that the values of concentrations depend strongly on the mixture fraction (which is a conserved scalar) defined as the normalized concentration of the species which is independent of reaction. Hence, Conditional moment closure (CMC) methods are useful for the prediction of the turbulent flow with chemical reactions. In this study, conditional scalar statistics are investigated by using the conditional moment closure methods and experimental data. It is shown that the conditional averages of concentration of reactant and product species approach the equilibrium limit (which correspond to the limiting case of the fast chemical reaction) in the downstream direction and the value of the conditional scalar (mixture fraction) dissipation decreases and its distribution varies in the downstream direction and comes to show the local minimum value near the point η = ξS (which is the stoichiometric value of the mixture fraction).

The use of shape memory alloy (SMA) components as actuators is an attractive option for some aerospace, automotive, and oil and gas exploration applications, especially when installation volume is limited. Fatigue failures constitute a major structural reliability issue confronting industrial entities looking to employ this technology. Knowing and understanding the failure mechanism and resulting fatigue life of SMAs is therefore necessary and useful for design and certification prior to commercial use. An in-house developed experimental set-up based on Joule heating was used to complete a comprehensive set of fatigue tests on SMA actuators composed of a nickel-rich Nickel-Titanium (Ni-Ti) alloy subjected to cyclic thermomechanical loadings. A special forced convective cooling environment has been designed that utilizes compressed air and vortex tubes to maintain the test environment at a temperature well below the martensitic finish temperature. To thermally cycle the specimen, a time controlled scheme developed using LabVIEW was used. The system design allows full thermal cycling of large SMA specimens in approximately 80 seconds. Consequently, each test (comprised of thousands of cycles) takes weeks to be completed. Actuation fatigue life results of a complete test matrix for specimens undergoing full transformation at multiple stress levels are presented. Significant spread was observed in the number of cycles to failure for specimens under same isobaric loading across different choice of applied stress. Post-mortem microscopic observation of failed specimens suggested that failure is linked to cracks initiating within Ni3Ti precipitates. Observations reported further suggest that the failure of the specimen may not be due to plastic strain to failure.

Full textAbstract:
High second-order nonlinearity (SON) in poled silica glasses [1] is of great interest for the development of linear electro-optic modulators and frequency converters monolithically integrated into optical fibres or planar glass waveguides. However, its origin [1, 2] is not fully understood. The extrinsic effects of poling time and voltage on second-harmonic (SH) generation in thermally-poled silica glass have been studied [1,3]. In particular the quadratic dependence of the maximum SH signal on the applied voltage indicated linear dependence of the SON on internal electric field [3]. There are several studies on intrinsic effects associated with defects [1, 4] and minority species such as OH [1,5] and Na [1, 6] in thermal poling of silica glasses. In this work we carried out a systematic analysis of oxygen related defects and impurities (OH and Na) in commercial fused silica glasses (without relying on their catalogue data) and discuss their effects on SON.

Full textAbstract:
The Southeast Coast Network (SECN) conducts long-term terrestrial vegetation monitoring as part of the NPS Inventory and Monitoring Program. The vegetation community vital sign is one of the primary-tier resources identi?ed by SECN park managers, and monitoring is conducted at 15 network parks (DeVivo et al. 2008). Monitoring plants and their associated communities over time allows for targeted understanding of ecosystems within the SECN geography, which provides managers information about the degree of change within their parks? natural vegetation. 2021 marked the ?rst year of conducting this monitoring e?ort at Chattahoochee River National Recreation Area (CHAT). Thirty vegetation plots were established throughout the park from June through July. Data collected in each plot included species richness across multiple spatial scales, species-speci?c cover and constancy, species-speci?c woody stem seedling/sapling counts and adult tree (greater than 10 centimeters [3.9 inches {in}]) diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass (i.e., fuel load) estimates. This report summarizes the baseline (year 1) terrestrial vegetation data collected at Chattahoochee River National Recreation Area in 2021. Data were strati?ed across two dominant broadly de?ned habitats within the park, including Piedmont Upland Forests and Piedmont Alluvial Wetland Vegetation and three land parcels: North?from Bowman?s Island to Abbotts Bridge, Middle?from Medlock Bridge to Gold Branch, and South?from Sope Creek to Palisades. Noteworthy ?ndings include: 299 vascular plant taxa were observed across 30 vegetation plots, including 29 species not previously documented within the park. The most frequently encountered species in each broadly de?ned habitat included: Piedmont Alluvial Wetland Vegetation: Chinese privet (Ligustrum sinense), sweetgum (Liquidambar styraciflua), eastern poison ivy (Toxicodendron radicans var. radicans), muscadine (Muscadinia rotundifolia var. rotundifolia), and smallspike false nettle (Boehmeria cylindrica). Piedmont Upland Forests: tuliptree (Liriodendron tulipifera var. tulipifera), eastern poison ivy, Virginia creeper (Parthenocissus quinquefolia), cat greenbrier (Smilax glauca), muscadine, mockernut hickory (Carya tomentosa), and black edge sedge (Carex nigromarginta). Sixteen non-native species categorized as invasive by the Georgia Exotic Pest Plant Council (GA-EPPC 2023) were encountered during this monitoring e?ort, including two not previously detected within the park?miniature beefsteak plant (Mosla dianthera) and Chinese holly (Ilex cornuta). Chinese privet and Japanese honeysuckle (Lonicera japonica) were the most frequently encountered and abundant invasive plant within the park. One species of special concern listed for Georgia (GADNR 2024) was observed during this monitoring e?ort?large-fruited sanicle (Sanicula trifoliata). Tuliptree, loblolly pine (Pinus taeda), boxelder (Acer negundo var. negundo), river birch (Betula nigra), and sweetgum were the most dominant species within the tree stratum of Piedmont Alluvial Wetlands of Chattahoochee River National Recreation Area; white oak (Quercus alba), loblolly pine, tuliptree, and mockernut hickory were the most dominant species of Piedmont Upland Forests. Chinese privet was the most abundant species within the sapling and seedling strata of Piedmont Alluvial Wetlands. The mortality rate of green ash (Fraxinus pennsylvanica) within Piedmont Alluvial Wetland plots was high, and it is likely these trees succumbed to impacts from emerald ash borer (Agrilus planipennis). The emerald ash borer is a wood-boring pest of ash (Fraxinus sp.) and is native to Asia. Since its discovery in the U. S. in the early 2000s, the insect has been responsible for the death of tens of millions of ash trees in the eastern and midwestern parts of the country. At this time, it is not certain whether the declining health of ash within Chattahoochee River National Recreation Area is due to emerald ash borer, edaphic factors that are responsible for natural mortality and decline, or other factors. Other threats to native vegetation within the park are: (1) the high prevalence of non-native, invasive plant species; (2) ?re suppression within oak-hickory; and (3) impacts from heavy browse by white-tailed deer (Odocoileus virginianus). All plots monitored during this sampling e?ort are scheduled to be resampled in 2024.

Full textAbstract:
The long-term motivation for this research is to transfer useful traits from a broad based gene pool of wild species into the narrow base of a cultivated crop in Cucumis. Our primary focus was to use polyploid prior to fertilization as a tool to overcome fertility barriers in the cross between C. melo and C. metuliferus. In conducting this research, we explored all combinations of tetraploid and diploid parents, in reciprocal combinations. Pollinations were made in both the field and greenhouse, using emasculated flowers, moneocious females, and open pollination by insect vectors, with morphological selection criteria. After observations of thousands of ovaries, we still have no definitive proof that this hybridization yielded viable embryos. The most promising results came from using tetraploid C. metuliferus, as the maternal parent in the interspecific hybridization, that set fruit were seeds contained small embryos that did not germinate. To obtain fruit set, it was important to rear plants in a cooler sunny greenhouse, as would be found in late winter/early spring. A second interspecific hybrid between wild and cultivated Cucumis, C. hystrix x C. sativus, yielded fertile progeny for the first time, while concomitantly working toward our primary goal. Two distinct treatments were necessary; 1) special plant husbandry was necessary to have the wild species produce fruit in cultivation, and 2) embryo rescue followed by chromosome doubling in vitro was required for fertility restoration. Backcrosses to crop species and resistance to nematodes are compelling areas for further work.

Monitoring plants and their associated communities over time allows for targeted understanding of ecosystems within the SECN geography, which provides managers information about the degree of change within their parks? natural vegetation. 2021 was the first year of conducting monitoring at Kennesaw Mountain National Battlefield Park (KEMO). Fourteen vegetation plots were established throughout the park from July through August. Data collected in each plot included species richness across multiple spatial scales, species-specific cover and constancy, species-specific woody stem seedling/sapling counts and adult trees (greater than 10 centimeters [3.9 inches {in}]) diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass (i.e., fuel load) estimates. This report summarizes the baseline (year 1) terrestrial vegetation data collected at Kennesaw Mountain National Battlefield Park in 2021. Data were stratified across two dominant broadly defined habitats within the park, Piedmont Upland Forests and Shrublands; and Piedmont Open Uplands and Woodlands. Noteworthy findings include: 184 vascular plant taxa (species or lower) were observed across 14 vegetation plots, including 27 species not previously documented within the park. The most frequently encountered species in each broadly defined habitat included: Piedmont Open Uplands and Woodlands: wafer-ash (Ptelea trifoliata var. mollis), white fringe-tree (Chionanthus virginicus), winged elm (Ulmus alata), hog plum (Prunus umbellata), Virginia creeper (Parthenocissus quinquefolia), and blackseed speargrass (Piptochaetium avenaceum). Piedmont Upland Forests and Shrublands: loblolly pine (Pinus taeda), tuliptree (Liriodendron tulipifera var. tulipifera), black cherry (Prunus serotina var. serotina), muscadine (Muscadinia rotundifolia var. rotundifolia), Virginia creeper, and cat greenbrier (Smilax glauca). Fourteen non-native species categorized as invasive by the Georgia Exotic Pest Plant Council (GA-EPPC 2023) were encountered within the park during monitoring. Chinese privet (Ligustrum sinense) was the most frequently encountered and abundant invasive plant within the park. Two species of special concern listed for Georgia (GADNR 2023) were observed during monitoring and included green, or Missouri, rock cress (Boechera missouriensis) and Stone Mountain mint (Pycnanthemum curvipes). Northern red oak (Quercus rubra), winged elm, and eastern redcedar (Juniperus virginiana) were the most dominant species within the tree stratum of Piedmont Open Uplands and Woodlands of Kennesaw Mountain National Battlefield Park; loblolly pine, sweetgum (Liquidambar styraciflua) and tuliptree were the most dominant species of Piedmont Upland Forests and Shrublands. Chinese privet was the most abundant species within the seedling stratum of Piedmont Open Upland and Woodland sites. Heavy browsing impacts by white-tailed deer (Odocoileus virginianus) were observed within the upland forests of Kennesaw Mountain National Battlefield Park. Long-term monitoring of vegetation structure and composition within the park can be used to determine forest regeneration patterns as they relate to changes in browsing pressure. Other threats to native vegetation within the park are (1) the high prevalence of non-native, invasive plant species, and (2) fire suppression within oak-hickory and pine-oak xeric and intermediate forests. Long-term monitoring data will aid in understanding how these threats over time impact the park?s forest communities. All plots monitored during this sampling are scheduled to be resampled in 2025.

Full textAbstract:
Amphibians are a Vital Sign indicator for monitoring long-term ecosystem health in seven national park units that comprise the Great Lakes Network. We present here the results for 2019 amphibian monitoring at Mississippi National River and Recreation Area (MISS). Appendices contain tabular summaries for six years of cumulative results. The National Park Service Great Lakes Inventory and Monitoring Network established 10 permanent acoustic amphibian monitoring sites at MISS in 2015. Acoustic samples are collected by placing automated recorders with omnidirectional stereo microphones at each of the 10 sampling sites. Temperature loggers co-located with the recorders also collect air temperature during the sampling period. Eight of the nine species of frog and toad known to occur at MISS were found in 2019. The most well distributed species were Eastern American Toad, Gray Treefrog, Green Frog, and Northern Leopard Frog. Rarer are Blanchard’s Cricket Frog, Cope’s Gray Treefrog, Wood Frog, and Boreal Chorus Frog. American Bullfrog has not yet been detected on GLKN monitored sites but has been recently confirmed nearby (Pigs Eye Lake). Two of the ten sites—MISS02, MISS04—were not sampled in 2019 due to flooding, and occupancy of early calling species at MISS06 was determined inconclusive due to a late sampling start. MISS07 was also deployed late and results may contain some false absences due to late sampling. We expanded analyses and reporting in 2018 to address calling phenology and to provide a second metric for tracking changes in abundance (as opposed to occupancy) across years. Occupancy analyses track whether or not a site was occupied by a species. Abundance is tracked by assessing how the maximum call intensity changes on sites across years, and by how many automated detections are reported from sites across years. Using two independent survey methods, manual and automated, with large sample sizes continues to return reliable results, providing a confident record of site occupancy for most species. There were some data collection issues in 2019, with two ARS units not deployed and two others with late start dates. This did reduce our ability to assess some sites and species. Summaries of 2019 data are shown in Appendices A, B and C, and cumulative data collection result summaries are provided in Appendix E. Since temperature logs show that the threshold of ≥40°F was already exceeded by 1 April in 2019, we recommend a 15 March start date for future data collection.

Full textAbstract:
Dark-induced senescence could pose a major problem in export of various crops including cuttings. The assumption of this work was that ROS which is increased at a specific organelle can serve as a signal for activation of cell senescence program. Hormones which reduce senescence in several crops like gibberellic acid (GA) and possibly cytokinin (CK) may reduce senescence by inhibiting this signal. In this study we worked on Pelargonium cuttings as well as Arabidopsis rosette. In Pelargonium the increase in ROS occurred concomitantly with increase in two SAGs, and the increase persisted in isolated chloroplasts. In Arabidopsis we used two recentlydeveloped technologies to examine these hypotheses; one is a transcriptome approach which, on one hand, enabled to monitor expression of genes within the antioxidants network, and on the other hand, determine organelle-specific ROS-related transcriptome footprint. This last approach was further developed to an assay (so called ROSmeter) for determination of the ROS-footprint resulting from defined ROS stresses. The second approach involved the monitoring of changes in the redox poise in different organelles by measuring fluorescence ratio of redox-sensitive GFP (roGFP) directed to plastids, mitochondria, peroxisome and cytoplasm. By using the roGFP we determined that the mitochondria environment is oxidized as early as the first day under darkness, and this is followed by oxidation of the peroxisome on the second day and the cytoplast on the third day. The plastids became less oxidized at the first day of darkness and this was followed by a gradual increase in oxidation. The results with the ROS-related transcriptome footprint showed early changes in ROS-related transcriptome footprint emanating from mitochondria and peroxisomes. Taken together these results suggest that the first ROS-related change occurred in mitochondria and peroxisomes. The analysis of antioxidative gene’s network did not yield any clear results about the changes occurring in antioxidative status during extended darkness. Nevertheless, there is a reduction in expression of many of the plastids antioxidative related genes. This may explain a later increase in the oxidation poise of the plastids, occurring concomitantly with increase in cell death. Gibberellic acid (GA) prevented senescence in Pelargonium leaves; however, in Arabidopsis it did not prevent chlorophyll degradation, but prevented upregulation of SAGs (Apendix Fig. 1). Gibberellic acid prevented in Pelargonium the increase in ROS in chloroplast, and we suggested that this prevents the destruction of the chloroplasts and hence, the tissue remains green. In Arabidopsis, reduction in endogenous GA and BA are probably not causing dark-induced senescence, nevertheless, these materials have some effect at preventing senescence. Neither GA nor CK had any effect on transcriptome footprint related to ROS in the various organelles, however while GA reduced expression of few general ROS-related genes, BA mainly prevented the decrease in chloroplasts genes. Taken together, GA and BA act by different pathways to inhibit senescence and GA might act via ROS reduction. Therefore, application of both hormones may act synergistically to prevent darkinduced senescence of various crops.

Saperda candida (Coleoptera: Cerambycidae) is native to the eastern USA and southeastern Canada. It was detected in Germany in 2008, where eradication efforts were undertaken. This beetle primarily infests woody hosts within the Rosaceae family, with Cydonia, Malus and Pyrus being significant cultivated hosts in North America. The larvae cause severe damage by girdling the trunks of young trees, leading to tree death. Improved pest management in the mid-20th century reduced its impact in orchards. Despite being an EPPO A1 Pest and an EU A1 quarantine pest, no classical biological control has been attempted. Potential natural enemies include 5 hymenopterous parasites (Cenocoelius saperdae, Echthrus niger, Monogonogastra agrili, Xylophrurus nubilipennis luctuosus and Sarcophaga sp.), which are not present in the EPPO region. Additional predators such as spiders, ants, click beetles, carabid beetles and several woodpecker species also contribute to natural control.

The Southeast Coast Network (SECN) conducts long-term terrestrial vegetation monitoring as part of the nationwide Inventory and Monitoring Program of the National Park Service (NPS). The vegetation community vital sign is one of the primary-tier resources identified by SECN park managers, and it is currently conducted at 15 network parks (DeVivo et al. 2008). Monitoring plants and their associated communities over time allows for targeted understanding of ecosystems within the SECN geography, which provides managers information about the degree of change within their parks’ natural vegetation. 2019 marks the first year of conducting this monitoring effort at four SECN parks, including Fort Matanzas National Monument (FOMA). Nine vegetation plots, located on Anastasia and Rattlesnake Islands, were established at Fort Matanzas National Monument in June. Data collected in each plot included species richness across multiple spatial scales, species-specific cover and constancy, species-specific woody stem seedling/sapling counts and adult tree (greater than 10 centimeters [3.9 inches {in}]) diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass (i.e., fuel load) estimates. This report summarizes the baseline (year 1) terrestrial vegetation data collected at Fort Matanzas National Monument in 2019. Data were stratified across two dominant broadly defined habitats within the park (Maritime Upland Forests/Shrublands and Maritime Open Uplands). Noteworthy findings include: Eighty-two vascular plant taxa (species or lower) were observed across nine vegetation plots, including eight species not previously documented within the park. The most frequently encountered species in each broadly defined habitat included: Maritime Upland Forests and Shrublands: saw palmetto (Serenoa repens), yaupon (Ilex vomitoria), southern/eastern red cedar (Juniperus silicicola + virginiana), American beautyberry (Callicarpa americana), and American burnweed (Erectites hieraciifolius). Maritime Open Uplands: sea oats (Uniola paniculata), earleaf greenbriar (Smilax auriculata), and dixie sandmat (Euphorbia bombensis). ne non-native species, Brazilian pepper (Schinus terebinthifolia), categorized as invasive by the Florida Exotic Pest Plant Council (FLEPPC 2019) was encountered in one Maritime Upland Forest and Shrubland plot during this monitoring effort. There were not any rare plants tracked by the Florida Department of Agriculture and Consumer Services (FDACS 2020) found during this monitoring effort. All plants located in these monitoring plots are fairly common throughout Florida, as well as across the Southeast Coast. Three species observed, however, are on the FDACS 2020 list of commercially exploited plants within the state. These include saw palmetto, cinnamon fern (Osmundastrum cinnamomeum), and coontie (Zamia integrifolia var. umbrosa). Southern/eastern red cedar and cabbage palmetto (Sabal palmetto) were the most dominant species within the tree stratum of the Maritime Upland Forest and Shrubland habitat type. Species that dominated the sapling and seedling strata of this type included yaupon and cabbage palmetto. More than 75% of the trees measured in the parks Maritime Upland Forest and Shrubland habitat type were alive and experiencing healthy vigor. Of the 22 trees that were dead, more than 50% of those were southern/eastern red cedar. Most of those individuals that were observed with moderate or severe decline and greater than 50% dieback were southern/eastern red cedars. Although red bay (Persea borbonia) was identified as one of the “principal understory tree” species within Fort Matanzas National Monument’s maritime forests in 2004 (Zomlefer et al. 2004), tree-sized individuals were rarely detected on plots during this monitoring effort. This may be in part due to the detection of laurel wilt disease within St. Johns County in 2006 (USDA 2021). Based on the low detection...

Full textAbstract:
The production of semantic annotations has gained renewed attention due to the development of anatomical ontologies and the documentation of morphological data. Two methods are proposed in this production, differing in their methodological and philosophical approaches: class-based method and instance-based method. The first, the semantic annotations are established as class expressions, while in the second, the annotations incorporate individuals. An empirical evaluation of the above methods was applied in the morphological description of Neotropical species of the genus Lepidocyrtus (Collembola: Entomobryidae: Lepidocyrtinae). The semantic annotations are expressed as RDF triple, which is a language most flexible than the Entity-Quality syntax used commonly in the description of phenotypes. The morphological descriptions were built in Protégé 5.4.0 and stored in an RDF store created with Fuseki Jena. The semantic annotations based on RDF triple increase the interoperability and integration of data from diverse sources, e.g., museum data. However, computational challenges are present, which are related with the development of semi-automatic methods for the generation of RDF triple, interchanging between texts and RDF triple, and the access by non-expert users.

Full textAbstract:
The original objectives of the approved proposal included: 1. Establishment of the biosynthetic pathways for pheromone production using labeled precursors and GC-MS. 2. The elucidation of a circadian regulation of key enzymes in the biosynthetic pathway. 3. The identification, characterization and confirmation of functional expression of the delta-desaturases. 4. The identification of gene regulatory processes involved in the expression of the key enzymes in the biosynthetic pathway. Background to the topic: Moths constitute one of the major groups of pest insects in agriculture and their reproductive behavior is dependent on chemical communication. Sex-pheromone blends are utilized by a variety of moth species to attract conspecific mates. The sex pheromones used are commonly composed of blends of aliphatic molecules that vary in chain length, geometry, degree and position of double bonds and functional groups. They are formed by various actions of specific delta-desaturases to which chain shortening, elongation, reduction, acetylation, and oxidation of a common fatty acyl precursor is coupled. In most of the moth species sex-pheromone biosynthesis is under circadian control by the neurohormone, PBAN (pheromone-biosynthesis-activating neuropeptide). The development of specific and safe insect control strategies utilizing pheromone systems depends on a clear knowledge of the molecular mechanisms involved. In this proposal we aimed at identifying and characterizing specific desaturases involved in the biosynthetic pathway of two moth pest-speciesof stored products, P. interpunctella and S. cerealella, and to elucidate the regulation of the enzymes involved in pheromone biosynthesis. Due to technical difficulties the second stored product pest was excluded from the study at an early phase of the research project. Major conclusions: Within the framework of the planned objectives we confirmed the pheromone biosynthetic pathway of P. interpunctella and H. armigera by using labeled precursor molecules. In addition, in conjunction with various inhibitors we determined the PBAN-stimulated rate-limiting step for these biosynthetic pathways. We thereby present conclusive evidence that the enzyme Acetyl Coenzyme A Carboxylase is activated as a result of PBAN stimulation. We also found that P. interpunctella produce the main pheromone component Z9, E12 Tetradecenyl acetate through the action of a D11 desaturase working on the 16:Acid precursor. This is evidenced by the high amount of incorporation of ²H-labeled 16:Acid into pheromone when compared to the incorporation of ²H-labeled 14:Acid. However, in contrast to reports on other moth species, P. interpunctella is also capable of utilizing the 14:Acid precursor, although to a much lesser extent than the 16:Acid precursor. Despite the discovery of nine different desaturase gene transcripts in this species, from the present study it is evident that although PCR detected all nine gene transcripts, specific to female pheromone glands, only two are highly expressed whereas the other 7 are expressed at levels of at least 10⁵ fold lower showing very low abundance. These two genes correspond to D11-like desaturases strengthening the hypothesis that the main biosynthetic pathway involves a D11 desaturase.
