UNLABELLED PREMISE OF THE STUDY We developed simple sequence repeat (SSR) markers from expressed sequence tags (ESTs) for the Solidago virgaurea complex, an ecologically and morphologically diverse species complex in the Japanese archipelago, to elucidate population genetic structure and examine taxonomic boundaries. • METHODS AND RESULTS Utilizing the RNA sequencing data obtained by next-...

Comparative analysis is the preferred method of inferring RNA secondary structure, but its use requires considerable expertise and manual effort. As the importance of secondary structure for accurate sequence alignment and phylogenetic analysis becomes increasingly realised, the need for secondary structure models for diverse taxonomic groups becomes more pressing. The number of available struc...

Background: Authority and year information have been attached to taxonomic names since Linnaean times. The systematic structure of taxonomic nomenclature facilitates the ability to develop tools that can be used to explore historical trends that may be associated with taxonomy. Results: From the over 10.7 million taxonomic names that are part of the uBio system [4], approximately 3 million name...

Climate change is expected to increase climate variability and the occurrence of extreme climatic events, with potentially devastating effects on aquatic ecosystems. However, little is known about the role of climate extremes in structuring aquatic communities or the interplay between climate and local abiotic and biotic factors. Here, we examine the relative influence of climate and local abio...

Taxonomic debates have been carrying on for decades over Formosan stag beetles, which consist of a high proportion of endemic species and subspecies featuring morphological variations associated with local adaptation. With the influence of periodical Pleistocene glaciations and the presence of several mountain ranges, the genetic differentiation and taxonomic recognition, within this medium-siz...

The present paper is an attempt to test the applicability of the trophic state index (TRIX) for scaling the eutrophication along the Bulgarian Black Sea coastal zone in concert with a number of chemical and biological descriptors aimed at selection of relevant indicators of marine coastal area ecological quality. The following environmental parameters have been considered: t(o), salinity, nutri...

Genetic structure and relationships of 130 lentil accessions belonging to six taxa were analysed. For this purpose, seven morphological traits and 31 polymorphic simple sequence repeat (SSR) primers were used for this purpose. Morphological traits grouped lentil accessions into five main clusters. SSR primers collectively amplified 139 polymorphic alleles in a range of 2-10 with an average of 4...
