Marine microorganisms contribute to the health of global ocean by supporting marine food web and regulating biogeochemical cycles. Assessing microbial diversity is a crucial step towards understanding ocean. The waters surrounding Iceland are complex environment where relatively warm salty from Atlantic cool down sink deep. Microbial studies in this area have focused on photosynthetic micro- na...

The diverse diets of common planktonic rotifers are described in detail from field and laboratory observations experiments. Also considered methodological approaches, rotifer feeding mechanisms, the availability natural waters less well-known food items (detritus, picoplankton, protozoans). Despite much variation among within genera, niches can be subdivided into four broad, overlapping categor...
