Microbial food webs are responsible for the main carbon flow in shallow eutrophic estuaries of the Baltic Sea. Bacteria account for respirative use most of the autotrophic production. Bottom-up influences are mainly directed to the phytoplankton. Massive increase of phytoplankton biomass has only li
Spatial and temporal fluctuations in rotifer abundance have been monitored along atrophic gradient in the northern Baltic . The most common rotifer was Synchaeta spp ., which had one abundance peak in June and one in September-October . Only during the latter period was the abundance significantly h
Cyanobacterial blooms 'occur regularly in summer in central parts of the Baltic Sea. They are mainly composed of Aphanizornenon sp. and Noditturia spumigena. Both species have almost similar ecological requirements and can roughly be considered a uniform functional group. In order to identify facto
Analysing the results of various authors recent studies in the pelagic region of the Baltic revealed that protozoan biomass is in the same range or even higher than metazooplankton biomass. The dominant groups of planktonic protozoans are heterotrophic pico-and nanoflagellates (various taxonomic gro
