What is the future of native freshwater crayfish in Croatia?
European indigenous crayfish species (ICS) experience major declines in their populations’ sizes and numbers. They are threatened by habitat degradation and pollution, overexploitation, climate change and spreading of non-indigenous crayfish species (NICS) that outcompete ICS through competitive exclusion and diseases transmission (eg. crayfish plague). In Croatian freshwaters four ICS and three NICS are distributed, with records of severe declines in ICS numbers and prevalence. Development of effective management plans for threatened ICS and threatening NICS are urgently needed in Croatia. Hence, our goal was to forecast potential future distribution for two ICS (noble and stone crayfish) and two NICS (signal and spiny-cheek crayfish) in Croatian freshwater habitats under different climate change scenarios. We used Species distribution models (SDMs) and different modelling algorithms were developed using presence only records of the four species as well as a set of environmental predictors that were selected based on their ecological relevance. Obtained SDMs results enabled us to evaluate the potential future distribution range and overlap of the two NICS and the two ICS under different climate change scenarios. ICS in the rivers of continental Croatia will be under the highest negative impacts of NICS and management efforts should be focused onto this region. Acquired results are discussed within the frame of the future ICS conservation programs development.
