Invasive alien phytoplankton of the Danube basin

Invazivni fitoplankton moţe značajno utjecati na bioraznolikost mijenjajući odnose izmeĎu vrsta kao i na pomicanje ekološke ravnoteţe. Invazivne fitoplanktonske vrste mogu proizvoditi toksine koji su štetni za ostali fitoplankton, zooplankton, razne vodene organizme i ljude. Dunav kao druga najveća rijeka Europe i dio kanala Rajna-Majna-Dunav vaţan je za riječni promet te samim time predstavlja koridor širenja invazivnih vrsta čime ugroţava autohtone vrste, zbog nepaţnje ili čak namjernog unošenja invazivnih vrsta. U ovom su radu obraĎene najznačajnije invazivne ili potencijalno invazivne vrste dunavskog bazena i to: Cuspidothrix issatschenkoi, Raphidiopsis raciborskii, Dolichospermum compactum, Gloetrichia echinulata, Rahidiopsis mediterranea, Monactinus simplex, Skeletonema potamos, Actinocyclus normanii.Invasive phytoplankton species can significantly affect the biodiversity changing species relationships and shifting of ecological balance. Invasive phytoplankton species can produce toxins which are harmful to other phytoplankton, zooplankton, different aquatic organisms and humans. The Danube is the second largest river in Europe, and as part of the Rhine-MainDanube channel is important for river traffic, and is therefore a corridor of invasive species endangering native species due to intentional or advisedly importing invasive species. In this paper, the most important invasive or potentially invasive species of the Danube basin are described: Cuspidothrix issatschenkoi, Raphidiopsis raciborskii, Dolichospermum compactum, Gloetrichia echinulata, Rahidiopsis mediterranea, Monactinus simplex, Skeletonema potamos, Actinocyclus normanii
