Molecular diversity of benthic ctenophores (Coeloplanidae)

Ctenophores

Ctenophores are also characterized by a pair of tentacles that they spread out like a web to catch zooplankton prey, such as small crustaceans and even small fish. There is even one group of ctenophores, the Beroids, which feeds on other ctenophores, and there are also a few groups that are benthic (they absorb their comb plates following embryonic development and creep along on the ocean floor...

Distribution, Diversity and Abundance of Benthic Foraminifera of the Northwstern Persian Gulf

During ROPME Winter Cruise 2006, twenty six surface sediment samples taken from the Northwestern part of the Persian Gulf at depths of 13-77m were analyzed for their foraminifera content. A total of 93 species of benthic foraminifera were found in the study area. The foraminifera assemblages were dominated by Ammonia beccarii, Spiroloculina excavata, S. depressa, Quinqueloculina dimidiata,...

Benthic bacterial diversity in submerged sinkhole ecosystems.

Physicochemical characterization, automated ribosomal intergenic spacer analysis (ARISA) community profiling, and 16S rRNA gene sequencing approaches were used to study bacterial communities inhabiting submerged Lake Huron sinkholes inundated with hypoxic, sulfate-rich groundwater. Photosynthetic cyanobacterial mats on the sediment surface were dominated by Phormidium autumnale, while deeper, o...

Neutral model analysis of patterns of marine benthic species diversity

Caswell (1976) proposed a neutral model which calculates a theoretical diversity for a sample of a given number of individuals and species assuming no biological interactions between species. Disagreement with the neutral model predictions have been suggested as a method of detecting disturbance or stress. To test these theoretical considerations, 98 samples of marine benthic organisms were sub...
