Modeling the habitat suitability of Botak-e-Fars, Cyprinion tenuiradius Heckel, 1849 and determining the impact of Climate Change on its distribution in Fars province

In this study, environmental and climatic variables were used as independent variables to determine the habitat suitability of Cyprinion tenuiradius in Fars Province and to investigate the impact of climate change on its distribution. Modelling was conducted in an R software environment using the MaxEnt algorithm. Based on the results, the performance and accuracy of modelling were good (AUC = 0. 790). Also, the mean annual temperature and annual precipitation were the most important variables in determining the habitat suitability and distribution of this species, respectively. According to the species prediction under optimistic and pessimistic scenarios of climate change in 2050 and 2080, it is expected that the distribution range of this species will decrease slightly under the optimistic scenario of 2050 and 2080. However, the distribution range under the pessimistic scenario of 2050 will be increased slightly while in the pessimistic scenario of 2080, its suitable habitats will be significantly increased. It is recommended to use the obtained results for management and conservation purposes.
