ASSESSING IMPACTS OF CLIMATE CHANGE ON DISTRIBUTION RANGE OF Squalius cephaloides (Battalgil 1942), ENDEMIC SPECIES IN TURKEY

Abstract

Continuing climate change is expected to influence the habitat of existing species and eventually result in changes in species distributions. Although climate patterns are essential to the ability of the species to survive in the region, for several taxa, some environmental conditions, such as land cover, geology, chemical soil properties, and topography, are also important for the availability of sufficient habitat. Also, the influence of air temperature and precipitation on the streamflow patterns and the water temperature is a change for aquatic life. Species distribution models (SDMs) were constituted using MaxEnt (maximum entropy) modelling in the Teşvikiye stream drainage in the northwestern region of Turkey for thick-lipped chub species (S.cephaloides), in this research. As a result of the 2100 projections (SSPs, 126, 245, 370, and 585), S.cephaloides will lose a significant part of their suitable habitats. Also, S.cephaloides showed positive allometric growth (b value 3,03-3,13) in length-weight evaluation.
