Project
Balkan rivers represent one of the most important hotspots of the European freshwater biodiversity. However, large dams continue to be built and many more are planned on these rivers, despite the scarce knowledge about the impact of dams on aquatic biodiversity in this area. The goal of this project is to analyze the impacts of large dams on Western Balkan rivers. Specifically, long-term changes in hydrological and temperature conditions and their effects on the long term changes of macroinvertebrate assemblages are studied.
Project
Goal: The main aims of this project were to study the distribution and dispersal dynamics of alien macroinvertebrates in Croatian freshwaters as well as biocontamination of large rivers and the effects of different types of habitat modifications (pollution, dams and reservoirs, changed hydromorphology) on the invasion process.
