EN Studies were carried out in shallow, eutrophic lake Pereszpa during vegetation season 1996. Samples were taken from the pelagic and littoral zone, where the distance between sampling sites were small (200-300 m). It was revealed in both zones quantitative and qualitative differentiation of phytoplan[...]

PL Wprowadzanie do wód przybrzeżnych obcych gatunków poprzez wody balastowe stało się poważnym zagrożeniem dla zachowania bioróżnorodności wielu morskich ekosystemów. Może to powodować nie tylko znaczne straty ekologiczne, ale również ekonomiczne. Zjawisko ma charakter antropogeniczny, chociaż częściow[...]
EN Introduction of non-indigenous species into the coastal waters via ballast water has become a serious threat for biodiversity of many marine ecosystems. It can result not only in considerable ecological loss but also in economical loss. The phenomena has anthropogenic character, although it happens [...]
