A review of paragnath morphology in Nereididae (Polychaeta)
The form and arrangement of hardened paragnaths on the pharynx of polychaetes in the family Nereididae has for 150 years been used as a principal system of characters to distinguish species and other taxonomic ranks. Recent studies have shown that phylogenetic relationships based solely on paragnaths give different topologies and clade support than relationships inferred from other character sy...
متن کاملMicrobial communities in the chemocline of a hypersaline deep-sea basin (Urania basin, Mediterranean Sea).
The Urania basin is a hypersaline sulfidic brine lake at the bottom of the eastern Mediterranean Sea. Since this basin is located at a depth of approximately 3,500 m below the sea surface, it receives only a small amount of phytoplankton organic carbon. In the present study, the bacterial assemblages at the interface between the hypersaline brine and the overlaying seawater were investigated. T...
متن کاملBiodiversity of Hardbottom Communities Grown on Artificial Substrata in the Saronikos Gulf (aegean Sea) - a Pilot Study
In this pilot study, we monitored for the first time the biodiversity of hardbottom communities grown on artificial substrata in two shallow water habitats of the Saronikos Gulf, Greece. Here we report preliminary results from the analysis of assemblages that established at a disturbed and an undisturbed study site as well as a list of macrofouler species. This research was performed within the...
متن کاملInvestigating the density and frequency of zooplankton in the Southeastern Basin of the Caspian Sea (Gorgan Bay)
Zooplanktons have an important role in food chain of the aquatic ecosystems, which acts as a food chain link between producers (phytoplankton) and higher nutritional levels. The purpose of this research was to identify and study the zooplankton density in the southeastern basin of the Caspian Sea (Gorgan Bay). Sampling was performed seasonally and samples were collected by zooplankton net (36 c...
