In the present study, Kabir kuh Section, related to the Seymareh or Lopha Limestone member (Gurpi Formation) have been Selected. The member has yielded a rich echinoid fauna and 21 species of Echinoid belonging to 14 genera are recognized and described. The Kabir Kuh section yielded two regular echinoid taxa: Salenia nutrix and Goniopygus superbus, one holectypoid taxa: Coptodiscus noemiae, two...

the genus astragalus l. (fabaceae) is reviewed from both phyloenetic and taxonomic points of view. as the largest genus of flowering plants it has attracted many researchers, but much work remains to be done. a short taxonomic history with special focus on infrageneric classification of the genus, a list of phylogenetic studies including the applied markers and sampling strategies as well a...

seed proteins of eight species of the genus suaeda (chenopodiaceae) were compared by means of polyacrylamide disc gel electrophoresis. different samples of the same species showed not less than 89% similarities, and geographical separation had no remarkable effect on seed protein patterns of the same species. morphological heterogenity, that creates difficulties in infrageneric classification, ...

This study was carried out to determine seasonal variation and zooplankton community structure in Karataş Lake, Southern Turkey. Zooplankton samples were collected seasonally between 2002 and 2003 in two stations using a zooplankton net of 55-µm mesh size. A total of 42 taxa were identified, including 19 taxa (45.2 %) Rotifera, 16 taxa (38.1 %) Cladocera, and 7 taxa (16.7 %). Copepoda. Among th...

A phylogenetic study of the Opopanax and Crenosciadium was conducted to elucidate their circumscription infrageneric relationships. Sequence data from nrDNA ITS, cpDNA matK trnL-F were used determine relationship. Polymerase Chain Reaction (PCR) amplifications all regions performed using universal primers. Maximum Likelihood (ML) trees constructed PAUP* software, another tree ITS sequences show...

plankton and semi-plankton samples collected from twelve floodplain lakes (beels) of majuli river island of the brahmaputra river basin, upper assam reveal rich cladocera assemblage of 48 species belonging to 32 genera and 7 families. this report assumes biodiversity value as ~65.0% and ~37.0% of the species, and ~78.0% and ~72.0 of genera of the taxon known from assam state of northeast india ...

Despite the common use of Thesium species as food and medicine prevailing systematic (taxonomic) difficulties genus, diversity phenolic compounds their chemophenetic value remain largely unknown. As part ongoing research on Thesium, composition were investigated at four taxonomic ranks: generic, infrageneric, interspecific infraspecific. Liquid chromatography–mass spectrometry, multivariate ana...
