Three species are identified; they are here shown to display unequivocal affinities with extant ophiuroid lineages. The assemblage comprises a new ophiacanthid genus and species, Juracantha hottingeri , which is closely related to extant Ophientrema , an ophiolepidid close to extant Ophiozonella ...
Here, we report a new genus and species,Famastraea catenata, from the late Famennian of the western part of the Holy Cross Mountains (Kowala) in Poland. Although this taxon is colonial, it displays many morphological characters very close to the typically late Famennian solitary speciesPalaeos...
This rich material (some eight species and four genera), collected bed by bed, allows us to propose an initial biostratigraphic, palaeobiogeographic, evolutionary and taxonomic synthesis of these mostly endemic faunas. The genus Epophioceroides n. gen. is new and three new species are identifi...
Pythium oligandrum, a non-pathogenic soil-inhabiting oomycete, colonizes the root ecosystem of many crop species. Whereas most members in the genus Pythium are plant pathogens, P. oligandrum distinguishes itself from the pathogenic species by its ability to protect plants from biotic stresses in ...
The freshwater turtle genus Mauremys (Testudines, Geoemydidae)--a textbook example of an east--west disjunction or a taxonomic misconcept? We compare 1036 bp of the mitochondrial cytochrome b gene (cyt b) from all six Mauremys species with 16 other taxa, representing both currently recognized ....
Selected strains were chosen for 16S rRNA gene sequencing and phylogenetic analyses confirmed that all strains isolated belonged to the genus Micromonospora and that some of them may represent new species. To determine the possibility that the isolates fixed atmospheric nitrogen, chosen strains were ...
The oil present in the seeds of the genus is known for its purgative action and it has been reported that the leaves of some species, including J. gossypiifolia, have the same effect [146]. Several ethnobotanical studies have also cited this purgative effect [144] and an in vivo study ...
The revised diagnoses of the genus Harpirhynchiella and its subgenera are provided. A new species, Harpyrhynchiella (Cypsharpirhynchus) apus sp. nov., is described from both sexes ex Apus apus (Linnaeus, 1758) (Apodiformes: Apodidae) in the northwest of Russia. Females of the new ...
The species described here can be placed confidently in the clade Discodorididae, but not in any of its subclades (traditionally taxa of genus rank). The unique, epithet-based name of the species is "aliciae Dayrat, 200529. Dayrat , B and Gosliner , T . 2005 . Species names and ...
Our analyses reaffirm the monophyly of Danaideae and Danais but reveal the paraphyly of Payera and Schismatoclada. The close relationship between the three Danaideae genera and Coursiana is supported. However, we found very little support for the inclusion of the latter genus in Payera as ...
