Texte intégralRésumé :
AbstractWe analysed cytochrome oxidase I (COI) barcodes for 35 putative fish species collected in the Scotia Sea, and compared the resultant molecular data with field-based morphological identifications, and additional sequence data obtained from GenBank and the Barcode of Life Data System (BOLD). There was high congruence between morphological and molecular classification, and COI provided effective species-level discrimination for nearly all putative species. No effect of geographic sampling was observed for COI sequence variation. For two families, including the Liparidae and Zoarcidae, for which morphological field identification was unable to resolve taxonomy, DNA barcoding revealed significant species-level divergence. However, the dataset lacked sufficient sensitivity for resolving species within theBathydracoandArtedidracogenera. Analysis of cytochromebfor these two genera also failed to resolve taxonomic identity. The data are discussed in relation to emergent priorities for additional taxonomic studies. We emphasize the utility of DNA barcoding in providing a valuable taxonomic framework for fundamental population studies through assigning life history stages or other morphologically ambiguous samples to parental species.

Texte intégralRésumé :
Abstract. Tackling the accelerated human-induced biodiversity loss requires tools able to map biodiversity and its changes globally. Remote sensing (RS) offers unique capabilities of characterizing Earth surfaces; therefore, it could map plant biodiversity continuously and globally. This approach is supported by the Spectral Variation Hypothesis (SVH), which states that spectra and species (taxonomic and trait) diversities are linked through environmental heterogeneity. In this work, we evaluate the capability of the DESIS hyperspectral imager to capture plant diversity patterns as measured in dedicated plots of the network FunDivEUROPE. We computed functional and taxonomical diversity metrics from field taxonomic, structural, and foliar measurements in vegetation plots sampled in Spain and Romania. In addition, we also computed functional diversity metrics both from the DESIS reflectance factors and from vegetation parameters estimated via inversion of a radiative transfer model. Results showed that only metrics computed from spectral reflectance were able to capture taxonomic variability in the area. However, the lack of sensitivity was related to the insufficient plot size and the lack of spatial match between remote sensing and field data, but also the differences between the information contained in the field traits and remote sensing data, and the potential uncertainties in the remote estimates of vegetation parameters. Thus, while DESIS showed some sensitivity to plant diversity, further efforts are needed to deploy suitable biodiversity evaluation and validation plots and networks that support the development of biodiversity remote sensing products.

Animals 10, no 8 (12 août 2020) : 1406. http://dx.doi.org/10.3390/ani10081406.
Texte intégralRésumé :
Vocalizations from birds are a fruitful source of information for the classification of species. However, currently used analyses are ineffective to determine the taxonomic status of some groups. To provide a clearer grouping of taxa for such bird species from the analysis of vocalizations, more sensitive techniques are required. In this study, we have evaluated the sensitivity of the Uniform Manifold Approximation and Projection (UMAP) technique for grouping the vocalizations of individuals of the Rough-legged Tyrannulet Phyllomyias burmeisteri complex. Although the existence of two taxonomic groups has been suggested by some studies, the species has presented taxonomic difficulties in classification in previous studies. UMAP exhibited a clearer separation of groups than previously used dimensionality-reduction techniques (i.e., principal component analysis), as it was able to effectively identify the two taxa groups. The results achieved with UMAP in this study suggest that the technique can be useful in the analysis of species with complex in taxonomy through vocalizations data as a complementary tool including behavioral traits such as acoustic communication.

Texte intégralRésumé :
Abstract The taxonomic analysis of sequencing data has become important in many areas of life sciences. However, currently available tools for that purpose either consume large amounts of RAM or yield insufficient quality and robustness. Here, we present kASA, a k-mer based tool capable of identifying and profiling metagenomic DNA or protein sequences with high computational efficiency and a user-definable memory footprint. We ensure both high sensitivity and precision by using an amino acid-like encoding of k-mers together with a range of multiple k’s. Custom algorithms and data structures optimized for external memory storage enable a full-scale taxonomic analysis without compromise on laptop, desktop, and HPCC.

Texte intégralRésumé :
Microarray analysis is a cultivation-independent, high-throughput technology that can be used for direct and simultaneous identification of microorganisms in complex environmental samples. This review summarizes current methodologies for oligonucleotide microarrays used in microbial ecology. It deals with probe design, microarray manufacturing, sample preparation and labeling, and data handling, as well as with the key features of microarray analysis such as specificity, sensitivity and quantification potential. Microarray analysis has been validated as an effective approach to describe the composition and dynamics of taxonomic and functional microbial communities, in environments including soil, compost, sediment, air or humans. It is now part of the technical arsenal available to address key issues in microbial community ecology, ranging from biogeography to ecosystem functioning.

Chessman, Bruce C. « New sensitivity grades for Australian river macroinvertebrates ». Marine and Freshwater Research 54, no 2 (2003) : 95. http://dx.doi.org/10.1071/mf02114.
Texte intégralRésumé :
The SIGNAL biotic index for river macroinvertebrates, originally developed and tested in eastern Australia, was revised for application to the entire continent. Macroinvertebrate survey data from the National River Health Program were used to set grade numbers between 1 and 10 to represent the water-quality sensitivities of 210 taxa. Grades were assigned at the taxonomic levels customarily used by government agencies (predominantly family level) and by community groups (mainly order). A new index version using these grades, SIGNAL2, was correlated with water temperature, turbidity, electrical conductivity, alkalinity, pH, dissolved oxygen, total nitrogen and total phosphorus. Because of natural spatial variation in water quality, index scores need to be interpreted in a local context or against site-specific predictions generated by the Australian River Assessment System (AUSRIVAS).

Hutchison, Leonard J. « Studies on the systematics of ectomycorrhizal fungi in axenic culture. V. Linear growth response to standard extreme temperatures used as a taxonomic character ». Canadian Journal of Botany 68, no 10 (1 octobre 1990) : 2179–84. http://dx.doi.org/10.1139/b90-284.
Texte intégralRésumé :
Ectomycorrhizal fungi showed characteristic differences in linear growth rate reduction when grown on modified Melin–Norkrans agar at 7 and 30 °C. The two standard temperature extremes differentiated ectomycorrhizal fungi into three growth response categories which reflected taxonomic affinity: sensitive, semitolerant, and tolerant. At 7 °C, species of Laccaria and Hebeloma generally exhibited tolerant or semitolerant growth, whereas at 30 °C growth tended to be restricted to species of Amanita, Laccaria, Suillus, and a few gasteromycetous fungi (e.g., Rhizopogon, Scleroderma, and Pisolithus). The results reveal the potential value of standard extreme temperatures as a taxonomic character for differentiating species or genera of ectomycorrhizal fungi in vitro. Tolerance or sensitivity to 30 °C by ectomycorrhizal fungi may reflect their association with specific host trees. Key words: ectomycorrhizal fungi, temperature, sensitivity, tolerance, cultures, identification.

Texte intégralRésumé :
RNA is the genetic material of bacteria except for the exceptions and out of that too 16S rna of the microbes courses of action be comprehensively use into regular microbial study and atomic developments dependable pined up for the ordered characterization and evolutionary investigation of organisms. Constrained within the currents aligning techniques, enormous sequence aligning of 16S rRNA genetic material amplicons surrounding the complete length of genesis not until now realistic. As a result, high-through put studies of microbial communities often do not sequence the entire16S rRNA gene. The test is to acquire dependable portrayal of bacterial networks through taxonomic classification of short 16S rRNA gene sequences known as hyper variable regions. However, the assortment of the most emerald hypervariable regions meant for phylogenetic estimate and taxonomic kind continues to be argued. Species explicit groupings inside a given hypervariable district comprise helpful final target destined in favor of problem-solving assay and other science related searches. Also, nix on its own region be able to distinguish among all microbes, consequently, organized study that think about the overall preferred position of every locale for explicit demonstrative objectives be desired. Here, first present an into silico pipeline for generating the 9 Hypervariable Regions from 16S rRNA sequences, using conserved regions and primers. The pipeline includes an error parameter taking into consideration in sertions, deletions and substitutions at some positions within the sequences. These hyper variable regions are then used to do a comparative study on the taxonomic sensitivity and accuracy of each of the 9 hyper variable regions. Each of the hypervariable regions are assigned taxonomy using QIIME (Quantitative Insights In to Microbial Ecology) and there sultant OUT table is used to generate abundance data. This abundance data is then used to decide the best hyper variable region for prediction at each level of the taxonomic hierarchy. In our study, we found that V2 region is best suited to assign phylum whereas V4 is better suited to decide deeper into the taxonomy, such as order and family. Also, certain examples are shown of 3 specific cases where a HV region has a bias against/towards a particular taxon, which can allow us money-spinning searching of change in microbial set of connections configuration together with the exceptional biosphere larger than space plus instant as well as can be functional straight away to initiative, similar to the Human Micro biome Project

Van, der Stockt Stefan Aloysius Gert. « A generic neural network framework using design patterns ». Diss., 2008. http://hdl.handle.net/2263/27614.
Texte intégralRésumé :
Designing object-oriented software is hard, and designing reusable object-oriented software is even harder. This task is even more daunting for a developer of computational intelligence applications, as optimising one design objective tends to make others inefficient or even impossible. Classic examples in computer science include ‘storage vs. time’ and ‘simplicity vs. flexibility.’ Neural network requirements are by their very nature very tightly coupled – a required design change in one area of an existing application tends to have severe effects in other areas, making the change impossible or inefficient. Often this situation leads to a major redesign of the system and in many cases a completely rewritten application. Many commercial and open-source packages do exist, but these cannot always be extended to support input from other fields of computational intelligence due to proprietary reasons or failing to fully take all design requirements into consideration. Design patterns make a science out of writing software that is modular, extensible and efficient as well as easy to read and understand. The essence of a design pattern is to avoid repeatedly solving the same design problem from scratch by reusing a solution that solves the core problem. This pattern or template for the solution has well understood prerequisites, structure, properties, behaviour and consequences. CILib is a framework that allows developers to develop new computational intelligence applications quickly and efficiently. Flexibility, reusability and clear separation between components are maximised through the use of design patterns. Reliability is also ensured as the framework is open source and thus has many people that collaborate to ensure that the framework is well designed and error free. This dissertation discusses the design and implementation of a generic neural network framework that allows users to design, implement and use any possible neural network models and algorithms in such a way that they can reuse and be reused by any other computational intelligence algorithm in the rest of the framework, or any external applications. This is achieved by using object-oriented design patterns in the design of the framework.Dissertation (MSc)--University of Pretoria, 2008.

Texte intégralRésumé :
How does the English School work as part of Empirical International Relations (IR) theory? The English School depends heavily on historical accounts, and this article makes the case that history and theory should be seen as co-constitutive rather than as separate enterprises. Empirical IR theorists need to think about their own relationship to this question and clarify what “historical sensitivity” means to them. The English School offers both distinctive taxonomies for understanding the structure of international society, and an empirically constructed historical approach to identifying the primary institutions that define international society. If Empirical IR is open to historical-interpretive accounts, then its links to the English School are in part strong, because English School structural accounts would qualify; they are, in other ways, weak because the normative theory part of the English School would not qualify. Lying behind this judgement is a deeper issue: if Empirical IR theory confines itself to regularity-deterministic causal accounts, then there can be no links to English School work. Undertaking English School insights will help open up a wider view of Empirical IR theory.

Texte intégralRésumé :
Abstract The Odonata have well resolved taxonomy, conspicuous diurnal adults, contact with aquatic and terrestrial environments, and a broad range of environmental sensitivity across species, making them a valuable group for environmental appraisals. Odonate nymphs are commonly tested in aquatic ecotoxicological and bioaccumulation studies and often applied with other aquatic macroinvertebrate taxa in pollution-based biotic indices. Some of the more recent work aims to explain the evolutionary context of contamination risk and to increase mechanistic understanding of contaminant effects. Adults or exuviae are typically featured in habitat quality assessments with tools such as the Dragonfly Biotic Index, regional lotic quality indices, and coarse taxonomic metrics that will be especially useful in regions lacking descriptions and keys. Adults are further being used in landscape disturbance assessments where removal of non-breeding occurrences can reduce noise and strengthen signal. The future may move toward macro-ecological health assessments enabled by extensive citizen science and vulnerability trait data.

Texte intégralRésumé :
A bioindicator species can be defined as “an organism that provides information on the environmental conditions of its habitat by its presence or absence, and its behavior.” In this sense, crustaceans present many biological and ecological characteristics that make them particularly useful as bioindicators (e.g., widespread distribution in different habitats and geographical areas, key role in community functioning, great diversity of life history strategies). Within Crustacea, the order Amphipoda has been considered an especially relevant and suitable group due to its direct development and its special sensibility to disturbances, among other reasons. Crustaceans can be used in biomonitoring studies in a wide variety of habitats (e.g., both soft- and hard-bottom substrata from intertidal to deep environments) and for different types of environmental stressors. An extensive amount of literature has reported the sensitivity of crustacean species to heavy metal contamination, sewage and desalination discharges, or engineering and aquaculture activities, among others. Special emphasis has been placed on the role of crustaceans in the most used indexes (e.g., AMBI, BENTIX, BOPA) developed to establish the environmental quality of European coastal and marine areas. Crustaceans are one of the groups with a higher contribution to those indexes, although their presence is not necessarily indicative of low environmental disturbances. Within amphipods, the importance of the family Caprellidae as a monitoring tool in environmental programs (e.g., trace metal or tributyltin pollution) is highlighted. Alien crustaceans can also play a pivotal role as bioindicators of anthropogenic pressures, and their likely influence on the accuracy of ecological assessment programs should be taken into account. Finally, there is an increasing need to improve our scarce taxonomic knowledge in many crustacean groups since that information is vital for the correct development of monitoring tools. Studies dealing with the species’ ecological and biological traits are also encouraged in order to understand the potential application of these species as bioindicators.

Texte intégralRésumé :
Banks soundness plays a crucial role in determining economic prosperity. As such, banks are under intense scrutiny to make wise decisions that enhances bank stability. Artificial Intelligence (AI) plays a significant role in changing the way banks operate and service their customers. Banks are becoming more modern and relevant in people’s life as a result. The most significant contribution of AI is it provides a lifeline for bank’s survival. The chapter provides a taxonomy of bank soundness in the face of AI through the lens of CAMELS where C (Capital), A(Asset), M(Management), E(Earnings), L(Liquidity), S(Sensitivity). The taxonomy partitions opportunities from the main strand of CAMELS into distinct categories of 1 (C), 6(A), 17(M), 16 (E), 3(L), 6(S). It is highly evident that banks will soon extinct if they do not embed AI into their operations. As such, AI is a done deal for banks. Yet will AI contribute to bank soundness remains to be seen.

Texte intégralRésumé :
This chapter concerns many of the challenges facing socio-cultural researchers of workplace e-learning when attempting a social critique of workplace elearning. These obstacles include finding a common ground to begin a socio-culturally based research and study of workplace e-learning as well as using an approach that authentically balances ‘distance’ and ‘education’ so that distance education does not become a ‘distant education’. The overwhelming emphasis on the technological artefacts of workplace e-learning are not having the expected impacts on workplace adult education and training to the degree so profoundly anticipated by so many. The research and study of workplace e-learning as a socio-culturally negotiated ‘idea’ may be one such way. To do this, notions of social theory, taxonomy, and the researcher, as they relate to the field of adult education, and for a global workforce of adult learners, now become necessary. The complexity of approaching the diverse field of adult education with respect to social theory is explained, as are some of the challenges of applying the socio-cultural sensitivity taxonomy by using adult education as a backdrop for understanding workplace e-learning. ‘Socio-cultural Sensitivity Taxonomy for Workplace E-learning’ is presented and comprises four basic elements: (a) a context (social change) and an impetus (social responsibility) for a socio-culturally based research and study of workplace e-learning; (b) two outcomes (normalization and universalization) of technological artefactual approaches to workplace e-learning research and study; (c) two dominant cultural paradigms (commodified knowledges and innovative artefact) shaping workplace e-learning historicity in organizations; and, (d) four workplace e-learning scenarios (instrumental instruction, rational training, dehumanizing ideologies, and social integration), that all present socio-cultural impacts for the workforce from socio-culturally insensitive, technological artefactual approaches to workplace e-learning research and study. Figure 1 and Figure 2, originally from the Preface, are re-presented here, more formally.

There are numerous ways in which faculty can deliver information in a blended course; however, the question remains as to which information is best suited to online delivery versus face-to-face. The focus of this chapter is on the flipped classroom, including a study in which a psychology statistics class was flipped and students’ statistical knowledge, attitudes toward statistics, and intercultural sensitivity were assessed. In order to understand the theoretical underpinnings of the classroom, the authors examine the flipped structure through Blended Learning Theory, Problem-or-Project-Based Learning Theory, and Cognitive Taxonomy Theory. Advantages and disadvantages to transitioning to such a format as well as applications to other courses and some of the best practices in a flipped course are discussed.

Texte intégralRésumé :
The development of data communication technologies promotes large-scale sensitive data collection and transmission in various application areas. The sensitivity and criticism of the exchanged data raise several privacy issues. A lack of privacy may cause moral and emotional damage and discrimination. It can even create an unequal society. To fill this gap, a better understanding of privacy concept and its requirements is required. This chapter presents a comprehensive survey of privacy-preserving in the modern era. It deals with this concept of privacy-preserving from all perspectives, classifying its requirements into content-oriented and context-oriented ones. Based on the taxonomy, privacy attacks are described, and approaches and mechanisms for privacy protection are reviewed. A future research direction about privacy preserving in various fields is finally exposed.

Texte intégralRésumé :
Banks have experienced chronic weaknesses as well as frequent crisis over the years. As bank failures are costly and affect global economies, banks are constantly under intense scrutiny by regulators. This makes banks the most highly regulated industry in the world today. As banks grow into the 21st century framework, banks are in need to embrace Artificial Intelligence (AI) to not only to provide personalized world class service to its large database of customers but most importantly to survive. The chapter provides a taxonomy of bank soundness in the face of AI through the lens of CAMELS where C (Capital), A(Asset), M(Management), E(Earnings), L(Liquidity), S(Sensitivity). The taxonomy partitions challenges from the main strand of CAMELS into distinct categories of AI into 1(C), 4(A), 17(M), 8 (E), 1(L), 2(S) categories that banks and regulatory teams need to consider in evaluating AI use in banks. Although AI offers numerous opportunities to enable banks to operate more efficiently and effectively, at the same time banks also need to give assurance that AI ‘do no harm’ to stakeholders. Posing many unresolved questions, it seems that banks are trapped between the devil and the deep blue sea for now.

Texte intégralRésumé :
The biological brain is able to form various feature maps and abstractions of sensory signals. For a characteristic sensory stimulus, a response is obtained from such a map at a location which corresponds to some quantitative feature value of the stimulus. This paper offers an explanation for this ability, using an idealized model of a self-organizing collective system. The model consists of a 2-D array of identical processing elements which receive a set of sensory signals in parallel and change their sensitivity or tuning to these signals, controlled by the input signals and also by the reactions from the neighboring elements. As a result, the various elements in the array become automatically adjusted in a continuous 2-D order. The coordinates on the array then correspond to some feature dimensions that are present in the input signals. For example, such a map may represent optical features, colors, spatial frequencies, acoustical frequencies, phonemes, taxonomic classifications, depending on the signal detectors used and stimuli presented at the input. This paper describes in what conditions a collective system starts to organize itself in this way and also gives several examples of maps already produced in computer simulations.

Texte intégralRésumé :
Abstract The development of unmanned aerial manipulators (UAMs) allows a novel class of flying robots to carry out a wide variety of tasks in difficult environments due to their versatility and autonomy. However, the different tasks that can be carried out might call for different control strategies. To this end, one needs to categorize the possible tasks accomplishable by UAMs. This paper proposes a novel taxonomy, which is the result of a video information acquisition methodology combined with a review of research works in the literature. The different elements of the taxonomy are separated using a higher level of abstraction in a way that the general description of the tasks are considered and not its operational details. To illustrate the fact that algorithms must adapt to different tasks, a description of the usual UAM architecture is carried out. Four categories of criteria are used in the taxonomy to differentiate all possible tasks. These categories are the interaction type, the actual task definition, the environment condition and the time sensitivity of the task. This taxonomy forms the basis for possible machine-learning-based task classifiers that could be used in autonomous UAMs control and mission planning. Multiple tasks defined in the taxonomy can be combined to accomplish complex missions.
