Abstract:

Methods of a multidimensional comparative analysis (MCA) rely on the ordering of a relatively homogeneous set of objects or features in order to make decisions regarding the choice of an object or feature according to a predetermined criterion. These methods are used to study directly immeasurable phenomena characterizing specific objects, subject to analysis. The article reviewed and characterized the methods of a multidimensional comparative analysis. An attempt was made to assess which methods may be particularly useful in an analysis of the capital market. The paper also presents examples

Abstract:

People who are concerned with security (such as security professionals) are naturally interested in methods of achieving security. This paper proposes an approach to creating a taxonomic framework of security methods. The taxonomic framework is developed using facet analysis based on a tetra-facet model of security, which identifies four facets of security: subject/scope of security, object of protection, source of insecurity, and method of protection. The taxonomic framework of security methods is created by combining two of the facets: source of insecurity and method of protection. The taxon

ABSTRACTIn spite of technical advances that have provided increases in orders of magnitude in sequencing coverage, microbial ecologists still grapple with how to interpret the genetic diversity represented by the 16S rRNA gene. Two widely used approaches put sequences into bins based on either their similarity to reference sequences (i.e., phylotyping) or their similarity to other sequences in the community (i.e., operational taxonomic units [OTUs]). In the present study, we investigate three issues related to the interpretation and implementation of OTU-based methods. First, we confirm the co

Abstract:

Research in human-associated microbiomes often involves the analysis of taxonomic count tables generated via high-throughput sequencing. It is difficult to apply statistical tools as the data is high-dimensional, sparse, and compositional. An approachable way to alleviate high-dimensionality and sparsity is to aggregate variables into pre-defined sets. Set-based analysis is ubiquitous in the genomics literature and has demonstrable impact on improving interpretability and power of downstream analysis. Unfortunately, there is a lack of sophisticated set-based analysis methods specific to microb

Abstract:

Passerid birds are cosmopolitan, with an African origin that dates back to the Early Tertiary. Whereas primitive representatives were insectivores and frugivores, the Miocene rise and spread of savanna grassland and adaptation to granivory resulted in an explosive radiation that is not reflected in the systematics of the group. Since evolution is complex, a classification that accurately replicates genealogy must be complex also, and far more taxa are required to depict this passerine diversification than are currently admitted.

Abstract:

Regional development is a complex economic category and a commonly used term today, yet it is vaguely defined and, therefore, interpreted implicitly and understood intuitively. From a statistical point of view, this concept, on account of its imprecision and ambiguity, is a kind of multidimensional characteristic which may be measured, though not conclusively. Due to the lack of a universal set of diagnostic variables adopted in taxonomic analyses, the quantitative approach to the examined research area, which is in most cases presented descriptively, poses the main problem.

Abstract:

Vocalizations of anuran amphibians have received much attention in studies of behavioral ecology and physiology, but also provide informative characters for identifying and delimiting species. We here review the terminology and variation of frog calls from a perspective of integrative taxonomy, and provide hands-on protocols for recording, analyzing, comparing, interpreting and describing these sounds. Our focus is on advertisement calls, which serve as premating isolation mechanisms and, therefore, convey important taxonomic information. We provide recommendations for terminology of frog voca

Abstract:

The situation in the labour market is conditioned by many factors that often have a local dimension. Identification of different levels of development of labour demand as well as potential of labour supply on the local level is a crucial element of diagnosis of reasons for regional and local diversity and implementation of an appropriate labour market policy. As there is available a variety of indicators describing regional labour relations, there is a need to create synthetic measure to include different aspects of the labour market situation. The aim of the paper is identification of the div

The applicability of confocal laser scanning microscopy (CLSM) for environmental monitoring of water bodies is demonstrated on several examples. Such CLSM methods as spectral imaging and microscopic spectroscopy of living cyanobacterial cells are considered. It is shown that fluorescence spectroscopy application can facilitate time-consuming process of taxonomic analysis of field samples and to make monitoring of water bodies during cyanobacterial blooms, on-line.

Abstract:

Abstract In a recent paper, Poe et al. assert that scientists should abandon clade-based approaches, particularly those using named taxonomic ranks. Poe et al. attempt to demonstrate that clade selection can have effects on the results of evolutionary analyses but unfortunately fall short of making any robust conclusions. Here, we demonstrate that the assertions made by Poe et al. have two important flaws: (i) an erroneous view of modern phylogenetic comparative methods; and (ii) a lack of statistical rigor in their analyses. We repeat Poe et al.’s analysis but using appropriate phylogenetic c

Abstract:

This study examines the effect of pre-extraction methods, namely, sonication, grinding, and lyophilization, and the use of peptide nucleic acid (PNA) blockers on the DNA recovery, diversity, and taxonomic resolution of bacterial and fungal communities in apple blossoms. Sonication was the most successful in recovering bacterial 16S and fungal ITS reads across all the collection points and plots. Lyophilization and grinding led to a significant reduction in fungal read counts, while PNA enhanced the recovery of bacterial 16S reads. Sonication improved the efficiency of DNA extraction and yielde

The paper presents the results of an analysis of hard coal quality diversion in narrow size fraction by using taxonomic methods. Raw material samples were collected in selected mines of Upper Silesian Industrial Region and they were classified according to the Polish classification as types 31, 34.2 and 35. Then, each size fraction was characterized in terms of the following properties: density, ash content, calorific content, volatile content, total sulfur content and analytical moisture. As a result of the analysis it can be stated that the best quality in the entire range of the tested size

This study investigates the morphometric variation of osteoderms across species and populations within the genus Acontias, especially in the A. meleagris species complex. Using both univariate and multivariate analyses, we evaluated whether size-independent osteoderm morphometrics could effectively differentiate taxa, particularly where minimal genetic divergence is present (i.e., cases where morphologically diagnosable species show little genetic separation). Univariate analysis revealed some significant morphometric variation across osteoderm regions, with sub-regions C and D showing the hig

Abstract:

Comparison of hierarchies aims at identifying differences and similarities between two or more hierarchical structures. In the biological taxonomy domain, comparison is indispensable for the reconciliation of alternative versions of a taxonomic classification. Biological taxonomies are knowledge structures that may include large amounts of nodes (taxa), which are typically maintained manually. We present the results of a user study with taxonomy experts that evaluates four well-known methods for the comparison of two hierarchies, namely, edge drawing, matrix representation, animation and agglo

Abstract:

Background.16S rRNA gene sequences are routinely assigned to operational taxonomic units (OTUs) that are then used to analyze complex microbial communities. A number of methods have been employed to carry out the assignment of 16S rRNA gene sequences to OTUs leading to confusion over which method is optimal. A recent study suggested that a clustering method should be selected based on its ability to generate stable OTU assignments that do not change as additional sequences are added to the dataset. In contrast, we contend that the quality of the OTU assignments, the ability of the method to pr
