Composition of protozoan communities at two sites in the coastal zone of the southern Baltic Sea

摘要: Protozoan communities were studied in the coastal zone of southern Baltic Sea. Stable environmental conditions and typical, bimodal seasonal changes protozoan biomass observed at sampling site Sopot (2003–2004). At Ustka (2007–2008), strong benthic resuspension irregular impacts fresh water resulted atypical with a summer peak only. The mean annual had similar values both sites: 43.2 μg C dm−3 38.6 Ustka. community was dominated by ciliates (48% biomass), whereas — heterotrophic nanoflagellates (53%).
