Abstract:
Anatomical characteristics have proved to be an invaluable asset for supporting taxonomic studies on different plant families, such as Asteraceae. Anatomical features can also help clarify taxonomical problems in the Aldama La Llave genus, especially among Brazilian representatives. The present study focussed on Aldama bakeriana, A. discolor, A. grandiflora and A. squalida. These species were chosen because they are difficult to identify taxonomically if the specimens have no flowers, they have biological and pharmacological potential and they are representative species from key morphological groups in the Aldama genus and could help in future taxonomical investigations. Aerial and underground vegetative organs from the four species were described herein for the first time and a comparative analysis was performed to highlight the unique features of each species and determine whether these species can be differentiated in terms of anatomy. All four species analysed were anatomically very similar. However, they could be differentiated on the basis of the set of anatomical features described for each species. On the basis of our findings, we concluded that anatomy is able to provide data to assist with the taxonomic problems within the four species analysed herein. The results also corroborated other studies on the Aldama genus.

Abstract:
Despite the great technological progress that has aided taxonomical identification, taxonomical issues remain for certain species found in remote and/or understudied geographical areas. The damselfly species Ischnura aurora has been the subject of a long-standing taxonomical debate, focused mainly on the existence of morphological and behavioural differences between Asian and Australo-Pacific forms of this species that could justify their placement into two different species. Here, we carried out a comparative morphological analysis of specimens currently identified as I. rubilio from India and I. aurora from Asia and Oceania, combined with the analysis of mitochondrial and nuclear sequence data, both developed by us and available in public repositories. Our results split the Asian and Australo-Pacific forms of I. aurora into two well-differentiated taxonomic units and, hence, different (albeit closely related) species, and support the specific status of I. rubilio. The results of our genetic analyses suggest the existence of a third (and even fourth) taxonomic unit, stressing the need to revise all available material belonging to the different I. aurora subspecies that have been described. Finally, we have identified several questionable DNA sequences currently available in public repositories, upon which previous conclusions about the phylogenetic position of I. rubilio are based. Our study stresses the importance of being able to link available DNA sequence data with voucher specimens as well as to carry out a careful examination of DNA sequence data prior to their inclusion in taxonomical studies.

Abstract:
A combination of taxonomical and molecular technique had done for authentic characterization of medicinally important five Phyllanthus species viz. P. acidus, P. emblica (small and large fruit form), P. niruri, P. reticulatus and P. urinaria. They were analyzed with several taxonomical parameters such as branching pattern, morphology of bark, leaves, flowers, fruits and seeds. A dichotomous bracketed key is created for easy identification of the species. RAPD analysis of five Phyllanthus species displayed that P. emblica and P. reticulatus were closely related whereas P. acidus and P. emblica were genetically distantly related. The genus Phyllanthus are diverse, as seen by the 71.68% polymorphism among the five studied species determined by RAPD analysis. The two forms (small and large fruit forms) of P. emblica showed similarity as well as dissimilarity in taxonomic and molecular features. Thus, a subtle revision is necessary in the taxonomical point of view to update their taxa. Dhaka Univ. J. Biol. Sci. 33(1): 121-131, 2024 (January)

Abstract:
A taxonomical revision of the Dacryopinax species in Mexico is presented in detail. Historically, only four species were known in the country: Dacryopinax elegans, D. lowyi, D. spathularia, and D. yungensis. Dacryopinax martinii is reported for the first time from Mexico. Taxonomical descriptions and remarks for all the species, based on macro- and micro-morphology, as well as geographical distribution are included, except for D. yungensis, as its record corresponded to a misidentification of D. spathularia. We propose a new phylogeny including the taxonomic position and relationships of all species, based on ITS and LSU sequence data. Finally, a dichotomous key to identify the four species in Mexico is provided.

Abstract:
Abstract. The present investigation is based on detailed taxonomical analyses combining light microscopy (LM), scanning electron microscopy (SEM) and critical reviews of publications and type material. This method revealed a higher number of diatom taxa than that reported for the Altiplano, reports that are based on LM and SEM, but force-fitting the taxa into their European relatives. It also became evident that some taxa often reported from the Altiplano do not occur or are less common in this region and that misidentifications are the consequence not only of force-fitting, but also of misinterpretation of the original protologues and illustrations (taxonomic concept drift). These findings have important repercussions on past palaeoecological assessments for the Altiplano, which have been based on ecological information for taxa developing in ecosystems of highly contrasting conditions. Here we present the case of three araphid diatoms, which were reported as known taxa from Europe and elsewhere, but in fact correspond to taxa described as new for the Altiplano or unpublished taxa. It is recommended that: (1) a flora for this region is developed utilizing sound microscopical data and reviewing pertinent type material, (2) key common taxa used for past palaeoecological studies in the Altiplano are reviewed using a taxonomically thorough and critical method, and (3) future palaeoecological studies for the Andes are supported by prior detailed taxonomical analysis.

Abstract:
In the Black and the Azov seas were found 140 species of Amphipoda, concern to 73 genera, 29 families and 3 suborders. Investigations of taxonomical diversity of Amphipoda from the Black and the Azov seas were made. Indices of Average Taxonomical Distinctness Δ+, variability in TaxD index Λ+, Cluster analysis and MDS ordination were made. Taxonomical structure of the Black and the Azov seas Amphipods by indices Δ+ hierarchical aligned and close to total taxonomical list of Amphipoda these seas. By indices Λ+ Amphipoda both the Azov and the Black seas close to expected in average level of variability of structure of taxonomical tree. Two regions – north-west of the Black sea and east of the Black sea were select by indices Δ+, Λ+ and method of MDS ordination. North-west of the Black sea characterize small taxonomical diversity (little of genera and families, many of species). Presence of estuary of big rivers and lagoons with small salinity waters was reason of small taxonomical diversity of north-west region of the Black sea. Amphipoda of East coast of the Black sea have big taxonomical diversity, but a little of species number. The reason – a small shelf, near to coast noted quick increase of depth and small of soft ground. Similarity of taxonomical lists of Amphipoda of north-west of the Black sea and Azov sea was identify by cluster analysis. Ponto-Caspian species live in estuary of big rivers and lagoons with small salinity waters and they characterize of taxonomical structure impoverishment in relation to taxonomical evenness of all Amphipods of the Black and the Azov seas.

Abstract:
abstractThis paper looks at a hitherto unexplored aspect of taxonomically organized concepts which has to do with word distributions in corpora of actual language use. In parallel to the psychological informativeness claim of the differentiation explanation, the question is addressed if concepts are internally more similar than their higher-ranked taxonomical relatives. This internal similarity is measured by making use of token-based vector space models. For each occurrence of a concept in the corpus a context vector can be calculated, which then serves as input for the internal similarity measure. Experiments are conducted for taxonomies taken from the Dutch counterparts of the English semantic domains animal and means of transportation. Results do not wholeheartedly agree with the imposition of a strict taxonomical order, but give rise to a new behavioural measure of the basic level.

Abstract:
Haplophyllum is one of the taxonomically difficult genera in the Rutaceae. Three Turkish endemic species of Haplophyllum, namely Haplophyllum myrtifolium, H. vulcanicum and H. megalanthum, have similar morphological features, therefore identification of the species are extremely difficult. In the present study, morphological, anatomical and palynological characteristics of the species are examined in order to understand the usefulness of these characteristics for systematics purposes. Morphological characteristics of leaves and corollas, absence/or presence of glandular hairs on the stem and inflorescence, expansion form of filaments and ovarium appendage are useful for specific delimitation among the species. Anatomical characters such as number of cortex layers and sclerenchymatic cell layers in stem, size of the vascular bundle in the midrib provide information of taxonomical significance. In addition, exine sculpturing pattern of pollen grains can be used for taxonomic purposes.

PurposeThe purpose of this paper is to synthesize taxonomical criteria that can be used for assessing research constructs and assess current business model conceptualizations. The paper attempts to show how the criticism plaguing current business model conceptualizations could be removed with future conceptual development against these taxonomical criteria.Design/methodology/approachThe paper synthesizes taxonomical criteria and assesses current business model conceptualizations.FindingsThe results of the paper revealed that the current business model concepts comply poorly with the taxonomical criteria. The assessment of taxonomical compliance in this paper exposed major opportunities for enhancements in the existing conceptualizations of business model.Research limitations/implicationsThe findings of the paper outline novel avenues for future research in developing more coherent and rigorous business model conceptualizations.Practical implicationsThe practical implications of the paper are that current conceptualizations of a business model are at best incommensurate and at worst even misleading. This paper presents criteria that may be used in guiding the necessary caution and careful deliberation when practical application of the current business model conceptualizations is enforced.Originality/valueThe paper is original in that it establishes the taxonomical criteria, which may be used in research seeking to develop more sound and rigorous business model conceptualizations. To advance this new field the paper concludes that the taxonomical criteria can aid in the future research endeavors to design relevant business model conceptualizations.

Taxonomic impediment is one of the main roadblocks to managing the current biodiversity crisis. Insect taxonomy is the biggest contributor to the taxonomic impediment, both in terms of the knowledge gap and the lack of experts. With this study, we tried to size the knowledge gap by analyzing taxonomical studies on the subfamily Aphidiinae (Hymenoptera: Braconidae) conducted from 2010 to 2021. All available taxonomic knowledge gathered in this period is critically summarized: newly described species, detection of alien species, published identification keys, etc. All findings are discussed relative to the current state of general taxonomy. Future prospects for taxonomy are also discussed.

Abstract:
ABSTRACT There are ∼1031 phage in the biosphere, making them the most abundant biological entities on the planet. Despite their great numbers and ubiquitous presence, very little is known about phage biodiversity, biogeography, or phylogeny. Information is limited, in part, because the current ICTV taxonomical system is based on culturing phage and measuring physical parameters of the free virion. No sequence-based taxonomic systems have previously been established for phage. We present here the “Phage Proteomic Tree,” which is based on the overall similarity of 105 completely sequenced phage genomes. The Phage Proteomic Tree places phage relative to both their near neighbors and all other phage included in the analysis. This method groups phage into taxa that predicts several aspects of phage biology and highlights genetic markers that can be used for monitoring phage biodiversity. We propose that the Phage Proteomic Tree be used as the basis of a genome-based taxonomical system for phage.

Abstract:
Annonaceae is one of the most important and economically valuable plant families in Malesia region. Taxonomical studies could contribute to further utilization and conservation of the studied taxa. Due to their importance, an update in the morphological characters and taxanomical position of Annonaceae is required. This study aims to characterize the taxonomical position and relationships of 24 species belongs to the family Annonaceae found in the Purwodadi Botanic Gardens. In this work, we reported the taxonomical position and the phenetic clustering of 24 Annonaceae species collected from the Purwodadi Botanic Garden, East Java, Indonesia. The taxonomical study was performed based on morphological and phenetic approach where 81 characters (leaves, stem, and flower) were used in the analysis. A dendogram was produced following the scoring of the character using statistical program PAST ver. 3.0. (Hierarchial Cluster Analysis using Jukes Cantor Similarity approach). The dendogram showed clear separation between members of sub-family Annonoideae and Malmeoideae; however Alphonsea javanica and Sageraea lanceolata were not grouped into their respective tribe or sub-family. Further studies are required to evaluate these taxonomical separations. Overall, from the 24 studied species, we found that they grouped into 2 sub-family (Annonoideae and Malmeoideae), 3 tribes (Annoneae, Miliuseae, and Uvarieae), and 13 genus (Alphonsea, Annona, Desmos, Fissistigma, Miliusa, Mitrephora, Orophea, Polyalthia, Popowia, Pseuduvaria, Sageraea, Stelechocarpus, dan Uvaria).

ABSTRACT Taxonomical classification of newly discovered viruses and reclassification of previously discovered viruses provide an important foundation for detailing biological differences of scientific and clinical interest. The development of molecular analytical methods has enabled finer levels and more precise levels of classification. Periodically, there is need to refresh the literature and common understanding of current taxonomic classification, which we attempt to do here in addressing changes in human and animal viruses of medical significance between 2012 and 2015.

A sistemática é a ciência que descreve, nomeia, classifica e determina as relações entre os seres vivos. Atualmente ela enfrenta alguns problemas como a falta de especialistas em alguns grupos e regiões pouco amostradas. Os fasmídeos ainda são pouco estudados no Brasil e não existe registro de especialistas na ordem, causando dessa forma, diversas dificuldades na identificação dos espécimes do táxon. Contudo, apesar desse baixo conhecimento é possível notar vários problemas taxonômicos e pouca literatura disponível. Com isso, este trabalho tem como objetivo reconhecer e listar as espécies de Phasmatodea originalmente descritos para o Brasil, além de tecer alguns comentários sobre o histórico taxonômico do grupo no país. Synopsis of Phasmatodea (Insecta) Described from Brazil Abstract. Systematics involves description, naming of taxa, classification and phylogenetics determination of evolutionary relationships among the living. The decline in taxonomists available and the lack of taxonomic expertise lead to the so-called taxonomical impediments. The diversity and distribution of the phasmids in Brazil is still little known as any taxonomist is available in the country. However, although this poor knowledge in the Brazilian phasmids, it is possible to observe many taxonomical problems, very few literatures available. Thus, in this paper we listed all species originally described from Brazil and pointed out some notes about the taxonomic history of the phasmids from Brazil.

Abstract:
The dandelions from Taraxacum sect. Erythrosperma are taxonomically well distinguished and ecologically restricted to warm and sunlit habitats of steppes, dry and sandy grasslands, and distributed in temperate regions of Europe and Central Asia, with some being introduced to North America. Despite the long tradition of botanical research, the taxonomy and distribution of dandelions of T. sect. Erythrosperma is still underexplored in central Europe. In this paper, by combining traditional taxonomic studies supported by micromorphological, molecular and flow cytometry analyses as well as potential distribution modelling we shed light on taxonomical and phylogenetical relationships between members of T. sect. Erythrosperma in Poland. We also provide an identification key, species-checklist, detailed descriptions of morphology and occupated habitats as well as distribution maps for 14 Polish erythrosperms (T. bellicum, T. brachyglossum, T. cristatum, T. danubium, T. disseminatum, T. dissimile, T. lacistophyllum, T. parnassicum, T. plumbeum, T. proximum, T. sandomiriense, T. scanicum, T. tenuilobum, T. tortilobum). Finally, conservation assessments performed using the IUCN method and threat categories for all the examined species are proposed.

Abstract:
We present a comprehensive taxonomic and nomenclatural review of the Portuguese oaks (Quercus L.), issuing from throughout biogeographical, historical, bibliographic, field and herbarium data. We propose a new annotated checklist for all taxa and nothotaxa belonging to Quercus L. genus in the Portuguese national territory, extending the analysis to the broader biogeographical context of Western Mediterranean Subregion. Fifteen herbaria collections were exhaustively studied and complemented by information retrieved from digital collections, resulting in the recognition of eleven native oaks. Further treatment at infraspecific level includes one subspecies and additional 23 nothotaxa. We designate 21 names as types and add a preliminary list of 150 cultivated trees, concurring to a total of 185 oak taxa, in total, found in Portugal. Moreover, we clarify the taxonomical status and reinstate both Quercus calliprinos Webb and Q. pseudococcifera Desf. as native for the Western Mediterranean subregion. We recover the concept of Q. faginea Lam., as the widespread Gall oak in Portugal and update its synonym list. We propose Q. broteroana and Q. estremadurensis as autonomous species within the European Q. robur s.l. broad group, alongside two newly circumscribed subsections inside Section Quercus. We describe three nothotaxa as new (Q. ×alvesii, Q. ×capeloana and Q. ×sampaioana) and approach the nomenclatural resolution of the remaining natural hybrids. Lastly, we provide an identification key, intelligible for non-specialists, including both native taxa and most frequent nothotaxa. We emphasise the importance of historical and literature review, combined with accurate biogeographical information, as paramount to coherent taxonomical resolution. Both specimens and their associated records were found of crucial significance to a taxonomical model that is, in the end, useful to biodiversity conservation.

Abstract:
Abstract Radiocarbon dating of the plant material is important for chronology of archaeological sites. Therefore, a selection of suitable plant samples is an important task. The contribution emphasizes the necessity of taxonomical identification prior to radiocarbon dating as a crucial element of such selection. The benefits and weaknesses of dating of taxonomically undetermined and identified samples will be analysed based on several case studies referring to Neolithic sites from Hungary, Slovakia and Poland. These examples better illustrate the significance of the taxonomical identification since plant materials of the Neolithic age include only a limited number of cultivated species (e.g. hulled wheats) and typically do not contain remains of late arrived plants (e.g. Carpinus betulus and Fagus sylvatica). For more accurate dating results cereal grains, fruits and seeds, which reflect a single vegetative season, are preferred. Among charred wood, fragments of twigs, branches and external rings should mainly be taken into account, while those of trunks belonging to long-lived trees should be avoided. Besides the absolute chronology of archaeological features and artefacts, radiocarbon dating of identified plant remains might significantly contribute to the history of local vegetation and food production systems.

Abstract:
Soil microbial communities’ assembly is strongly tied to changes in temperature and moisture. Although microbial functional redundancy seems to overcome taxonomical composition changes, the sensitivity and resilience of soil microbial communities from subtropical regions in response to seasonal variations are still poorly understood. Thus, the development of new strategies for biodiversity conservation and sustainable management require a complete understanding of the soil abiotic process involved in the selection of microbial taxa and functions. In this work, we used state of the art molecular methodologies (Next Generation Sequencing) to compare the taxonomic (metataxonomics) and functional (metatranscriptomics) profiles among soil samples from two subtropical natural grasslands located in the Pampa biome, Brazil, in response to short-term seasonal variations. Our data suggest that grasslands maintained a stable microbial community membership along the year with oscillation in abundance. Apparently soil microbial taxa are more susceptible to natural climatic disturbances while functions are more stable and change with less intensity along the year. Finally, our data allow us to conclude that the most abundant microbial groups and functions were shared between seasons and locations reflecting the existence of a stable taxonomical and functional core microbiota.

Full text
Abstract:
The taxonomic diversity center of Schistochilopsis is in East Asia, where the genus also shows the highest genetic diversity and morphological plasticity. The integrative survey of Schistochilopsis in East Asia was the main goal of the present account. Plant materials were obtained from recent collections made by authors in various parts of amphi-Pacific Asia; several types of specimens were also studied. The study includes phylogenetic reconstructions from nuclear ITS1,2, chloroplast trnL and trnG sequences, and anatomo-morphological, biogeographical, and taxonomical analyses. As a result, it was concluded that S. obscura should be transferred to Lophozia s. str. and S. grandiretis to the newly described genus Protochilopsis. Lophozia boliviensis was found to be part of the Andean–Sino-Himalayan taxon belonging to Schistochilopsis. The species status of S. hyperarctica and S. opacifolia was not confirmed. Substantial genetic variation is observed within S. incisa with possible cryptic sympatric distributed entities. The taxonomical section of the paper provides a discussion on the status, distinctive morphological traits, distribution, and ecology supplemented with the morphological description for poorly understood taxa. In the vast majority of cases, the illustrations and photographs made from the types and living material are provided.

Abstract:
The present part of the series provides new records of locally introduced native species in Hungary (Apium repens, Crypsis schoenoides, Limonium gmelinii, Rumex confertus, Sagina apetala). The spread of Crypsis schoenoides and Limonium gmelinii on roadsides is due to winter salting of roads, whereas the appearance of Apium repens and Sagina apetala is likely the consequence of the use of soil or peat material containing their seeds. The reports of Knautia dipsacifolia from the northern part of the Great Hungarian Plain and Spiraea crenata from the Hungarian–Romanian–Ukrainian border region is ascertained here concluding that the report of the first taxon was based on a misidentifi cation of K. drymeia, whereas the record of Spiraea crenata is a consequence of mislocation. New records of two spreading aliens (Eragrostis virescens, Sporobolus vaginifl orus) are discussed here along with a herbarium revision of Eragrostis, which showed that all previous Hungarian records of Eragrostis parvifl ora refer to E. virescens. Further species discussed in the paper escaped from cultivation (Asparagus verticillatus, Euphorbia characias, Nassella tenuissima, the latter two new for the country). The first record of the sedge hybrid Carex ×leutzii in Hungary is also presented.
