Gypsophila with approximately 150 speciesrepresents the fourth largest genus of Caryophyllaceae and the second genus of tribe Caryophylleae. Iran is the second main center of Gypsophila diversity with 38 species in the world. Considering Gypsophila as one of the most polymorphic genus of the family andalmost half of its taxa distributed in Iran as endemic, thus makes it as a significant genus f...

Taxonomic delimitation of Disepalum (Annonaceae) is contentious, with some researchers favoring a narrow circumscription following segregation of the genus Enicosanthellum. We reconstruct the phylogeny of Disepalum and related taxa based on four chloroplast and two nuclear DNA regions as a framework for clarifying taxonomic delimitation and assessing evolutionary transitions in key morphologica...

the alien polychaetes are widely distributed in the whole mediterranean sea as well as in theegyptian waters. the objective of this study is to highlight the distribution and abundance of the alienpolychaetes along the alexandria coast, their contribution to the total polychaete community and the changesthey caused in the community structure. through monthly sampling polychaetes were collected ...

the plankton and semi-plankton samples examined from mizoram state of northeast india (nei) revealed speciose and diverse rotifera assemblage including a total richness (s) of 162 species belonging to 19 families and 35 genera. the reports of six species new to india, four species new to nei and 76 new records to mizoram merit biodiversity interest. the occurrence of one australasian, one orien...

our plankton and semi-plankton collections from twelve floodplain lakes (beels) of majuli river island, upper assam reveal 124 rotifer species (32 genera and 17 families); these merit biodiversity value as ~52.0% and ~30.0% of species, ~68.0 and ~45.0% of  genera and ~74.0 and ~65.0% of the families of the phylum known from northeast india (nei) and india, respectively. two species are new to i...

In this study, the genetic diversity of Iranian populations of two widespread Stenus species representing two ecomorphological forms, the "open living species" Stenus erythrocnemus Eppelsheim, 1884 and the "stratobiont" Stenus callidus Baudi di Selve, 1848, is presented using data from a fragment of the mitochondrial COI gene. We evaluate the mitochondrial cytochrome oxidase I haplotypes and th...

Abstract Advances in high-throughput DNA sequencing are allowing faster and more affordable generation of molecular phylogenetic trees for many organisms. However, resolving relationships at species level is still challenging, particularly taxonomically difficult groups. Until recently, the classification Ochna had been based only on morphological data. Here, we present first comprehensive phyl...

large benthic foraminifera and dasycladalean green algae are the most common and important (micro) fossils in lower cretaceous shallow-water sediments of the tethyan realm. in this paper, we introduced such taxa and their importance in age dating of lower cretaceous strata in the kopet-dagh sedimentary basin. also, according to determinations of index taxa (fauna and flora) in this period, the ...
