Abstract:

Recent molecular phylogenetic studies of Camphorosmoideae (Chenopodiaceae) demonstrated that Camphorosma is monophyletic. Palynomorphological peculiarities are used in taxonomy as additional diagnostic features and pollen analysis. Pollen morphology was studied using light and scanning electron microscopy, based on 13 specimens belonging to four species (C. annua, C. lessingii, C. monspeliaca and C. songorica). The aim of this research was to provide new data on pollen characteristics of the above mentioned species and to evaluate their taxonomic value. The results obtained show that pollen gr

Abstract:

Insect male genitalia show an evolutionarily variable morphology that is valuable for both species identification and phylogenetic analyses. However, we often encounter some difficulties when conducting relevant studies due to only quantitative variations exhibited in male genitalia. In this study, based on the taxonomy of the <i>Macrolycus dotatus</i> species group (a total of seven species, including three new species described here), we analyzed the male genitalia shapes by GM and then constructed the phenotypic relationships by UPGMA, NJ and MP analyses. The results demonstrated that the s

The high level of diversity within the family in addition to other unusual features have reflected in poor understanding of its phylogenetics.

Morphological analyses were based on skull characteristics and male genitalia.

Abstract:

Taxonomy of the calcified marine red macroalgal genus Jania (Corallinales, Rhodophyta) is traditionally built on the comparative analyses of vegetative and reproductive morpho-anatomical characters. However, Jania species often display high levels of morphological plasticity leading to frequent homoplasies. Cryptic speciation and the occurrence of overlapping diagnostic characters between some species often compromises species identification based on the type method. Molecular methods represent powerful tools to help test morphology-based classifications, delineate morphologically challenging

Abstract:

Abstract Rhizocephalans are abundant members of marine ecosystems and are important regulators of crustacean host populations. Morphological and ecological variation makes them an attractive system for evolutionary studies of advanced parasitism. Such studies have been impeded by a largely formalistic taxonomy, because rhizocephalan morphology offers no characters for a robust phylogenetic analysis. We use DNA sequence data to estimate a new phylogeny for 43 species and use this to develop a revised taxonomy for all Rhizocephala. Our taxonomy accepts 13 new or redefined monophyletic families.

Abstract:

Abstract A comprehensive phylogeny of species relationships of the Auchenipteridae is reconstructed here with a large-scale taxon sampling based on combined morphological and molecular datasets. The hypothesized phylogeny includes most species of Auchenipteridae (97 of 124 valid species) and multiple members of siluriform families as an outgroup (32 species) to embrace the diversity of forms among related catfishes. As the first large-scale phylogeny of the Auchenipteridae, comparison between taxa included information from both morphology (264 characters) and mitochondrial and nuclear molecula

Abstract:

The Amazon region contains a great diversity of species, and the Amazon River basin accounts for almost 20% of all the freshwater in the world. Despite the favorable environmental conditions in this region, little is known about the cyanobacterial diversity of this waterbody, especially at the mouth of the river. In this paper, we used the polyphasic approach to identify 14 cyanobacterial strains isolated in the Amazon River on the inlet site from a drinking water supply located close to the river mouth. The isolated strains were characterized based on morphology, behavior in culture, 16S rRNA

Phylogenetic analysis was conducted based on a combined dataset of internal transcribed spacer and nuclear ribosomal RNA large subunit sequences. The phylogenetic reconstruction revealed that the six new species each formed an independent lineage, and the samples of C. trigonospora fr

In China, species of the genus Sicista are notoriously rare and elusive, making specimen collection exceptionally difficult. Sicista concolor is a poorly studied species within the genus, and its phylogenetic relationships and evolutionary history remain largely unexplored.
