A new locality of Schoenoplectiella mucronata – an endangered and warm-temperature wetland species was found in Western Polesie (Eastern Poland). The new station is situated far away to the north-east from all known Polish sites and belongs to the easternmost one within European range of the species. The mesotrophic Lake Kleszczów in which we have found a new population of S. mucronata was characterised...
The majority of ecological research on the food web has so far focused more on sea and lake ecosystems than on peatbog habitats. The primary objectives of this paper were to analyze the protozoa, metazoa, and macroinvertebrate assemblages in different types of peatbogs, and to assess the influence of potential predators on protozoa communities. Sampling was done in six peatbogs from May to October...
Mining activities affect a landscape in different ways, including by the formation of subsidence troughs, which after being inundated form wetlands and lakes. The development of new mining reservoirs may give a unique opportunity to study the early stages of colonization by various freshwater communities, including phytoplankton. Our paper presents the results of phycological research undertaken in...
Mass occurrence of nuisance algal species Gonyostomum semen is observed in European humic lakes since 1970s, initially in the Scandinavian countries, then in eastern, central and western part of the continent. In 2002 mass appearances of this flagellate were found in three of 12 investigated humic lakes situated in the Eastern Poland. Lakes with Gonyostomum were situated within small geographical...
