“…1) between the years 1977 and 2019 (mostly after 1990) and 10% of the occurrence records have coordinates. The species occurrence records that were used to construct the articles were as follows: Altunışık et al, 2016;Başoğlu & Baran, 1977;Bülbül et al, 2015;Cogălniceanu et al, 2013;Çördük et al, 2018;Eroğlu et al, 2017;Fischer et al, 2019;Iftime & Iftime, 2016;Koç et al, 2018;Kukushkin & Doronin, 2013;Mollov & Valkanova, 2009;Petrov et al, 2006;Poulakakis et al, 2005aPoulakakis et al, , 2005bPsonis et al, 2017;Sokolov, 2019;Stănescu et al, 2013;Tomovic et al, 2018;Tok & Çiçek, 2014;Urošević et al, 2015 The Maxent algorithm assumes that all occurrence records on the study area are equally likely to be sampled (Merow et al, 2013). To reduce the clustering of occurrence points, caused by the survey bias, they were filtered (Boria et al, 2014;Kadmon et al, 2004) by 10 km, 15 km, and 20 km distance thresholds via using 'spatial thinning' application on the Wallace platform v. 1.0.6 (Kass et al, 2018) and; as a result, 20 Km spatial thinning with 153 occurrence points was used to construct the model due to 10 Km (243 occurrence points) and 15 Km (193 occurrence points) spatial thinning were not able to remove clustering (Fig.…”
