Sažetak
Indigenous European freshwater crayfishes (ICS) have undergone significant declines in populations’ numbers and sizes across their ranges. Apart from being threatened by climate change and habitat loss and deterioration, ICS are endangered by non-indigenous crayfish species (NICS). NICS displace ICS through both competitive exclusion and transmission of diseases such as crayfish plague. In Croatia all 4 ICS species have undergone severe declines in population abundance and numbers, in part due to the spread of the 3 NICS species. In order to protect threatened ICS, and manage fast dispersal and invasion range expansion rates of the two NICS recorded in Croatia (the signal crayfish and the spiny- cheek crayfish), the aim of this study was to predict their potential current and future distribution in continental Croatia. We developed Species distribution models (SDMs) using presence only records of the two NICS species and a set of bioclimatic predictors selected based on their ecological relevance, excluding highly correlated ones. Resulting SDMs enabled us to evaluate the potential contemporary range of the two NICS as well as to predict the impact of ongoing climate change onto their future distribution in Croatia. Obtained results will facilitate prioritisation of locations where NICS will probably establish and where their negative impacts on ICS will be most pronounced. Application of acquired results in the future ICS conservation and NICS management programs is discussed.
