Alien macroinvertebrates in Croatian freshwater: distribution, biocontamination of large rivers and effects of habitat modifications on invasions

Freshwater worldwide has been invaded by many alien macroinvertebrates with major consequences for native species, ecosystem processes, and often resulting in high economic losses. Knowledge on alien species distribution and dispersal dynamics is a prerequisite for prevention of future invasions, and for prediction and reduction of their undesirable impact. The aim of this talk was to present an updated list of alien and invasive freshwater macroinvertebrate species in Croatia based on literature and field data, and to analyse the origin, distribution and potential vectors of spread. Further, biocontamination of major large rivers (Danube, Sava, Drava, Mura and Kupa) and effects of habitat modification like changed hydromorphology on population densities of invasive species was presented and disscused.
