New locality record of Podarcis tauricus tauricus (Pallas, 1814) (Squamata: Lacertidae) from the western Black Sea region of Turkey

Abstract

distinguished from P. t. tauricus by the following: large SVL; more pointed head; the tail length is nearly twice the length of the head and body; thickness of neck not constricted; frontal shield as long as frontoparietal; occipital shield as long as or a little longer than the interparietal shield; feebly keeled dorsum scales; less-pointed caudal scales (Lehrs, 1902). P. t. thasopulae is different from P. t. tauricus in having a more yellowish and mustard-colored ventral region, and a brownish and bronze-colored middle part of the dorsum.

New Locality Record of the Italian Wall Lizard, Podarcis siculus (Rafinesque-Schmaltz, 1810) (Squamata: Lacertidae) from the Western Black Sea Region of Türkiye

“…Field observations carried out in Türkiye in recent years have revealed that some amphibian and reptile species exist in the country (Bülbül et al, 2016). In addition, these studies have shown that some species known to exist in Türkiye are also found in different geographical regions where they were not previously distributed (Bülbül et al, 2015;Olgun et al, 2015;Candan et al, 2020).…”

Identifying the Past, Present, and Future Distribution Patterns of the Balkan Wall Lizard (Sauria: Lacertidae: Podarcis tauricus) by Ecological Niche Modelling

“…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.…”

“…3). This could be due to several reasons: 1) Known distribution area of the species is expanded with new studies (Tok & Çiçek, 2014;Bülbül et al, 2015;Gül & Tosunoğlu, 2017;Fischer et al, 2019) and the results of the study might support it, 2) Italy and the south part of Dinaric Alp Mountains are not inside the distribution area of the species historically, even though it had been, the barrier status of the Alps could have blocked northwards directed range expansions from the Italian Peninsula (Sudhaus et al, 1997). Likewise Italy, Sicily was also overpredicted and these findings could be the result of modelling weakness.…”

“…Among the wall lizards, the Balkan wall lizard (Podarcis tauricus, Pallas, 1814) is one of a few species of the wall lizard genus having large distribution range from the Crimean Peninsula, and southwestern Ukraine to the southeastern part of Czech Republic (Fischer et al, 2019;Rehák et al, 2022) in the north and Greece (Gasc et al, 1997;Sindaco & Jeremčenko, 2008;Uetz & Hallermann, 2022) and northwestern part of Türkiye (Başoğlu & Baran, 1977;Baran et al, 1992;Tok & Çiçek, 2014;Bülbül et al, 2015;Gül & Tosunoğlu, 2017) in the south. The Balkan wall lizard is a diurnal, heliothermic, medium-size, actively foraging ground-dwelling lizard having a total body length up to 22 cm (Başoğlu & Baran, 1977;Ljubisavljević et al, 2010).…”
