Özet

Climate change affects the distribution areas of terrestrial and aquatic organisms. This study was conducted to investigate the effects of climate change on the current and future distribution of Anatolian sea trout, Salmo coruhensis. Nineteen Bioclimatic (Bio 1-19) and eight environmental data have been used in the study. Future distribution model for Interdisciplinary Research on Climate (MIROC-ESM) and Geophysical Fluid Dynamics Laboratory Coupled Model (GFDL CM3) 2050 and 2070 emission scenarios (RCP 2.6 and 8.5), current distribution Global River Classification (GloRiC) data and bioclimatic data were used. Global River Classification (GloRiC) data evaluation has determined that S. coruhensis is currently distributed in streams with minimum air temperature (long-term average of the minimum air temperature of the coldest month) range of -5.6 and 3.9 degrees C. The suitable distribution areas of the species expand according to 2050 and 2070 RCP 2.6 emission scenarios but decrease to 8.5 scenario. According to the 2050 and 2070 8.5 emission scenario, the species lose the distribution areas below 1300 altitude. Mountain streams will be an important shelter for Salmo coruhensis in the future. Considering the future habitat losses of S. coruhensis (IUCN - category NT) species, conservation plans are essential; therefore, the results of the study may contribute to future species conservation plans.
