... Mediterranean amphibians regularly represent groups of closely related species that are themselves characterized by high intraspecific genetic variability, with evolutionary lineages of varying ages (Ambu et al., 2023;Dufresnes et al., 2020a;Fijarczyk et al., 2011;Martinez-Solano et al., 2006;Pabijan et al., 2015;Recuero et al., 2012;Vences et al., 2013;Wielstra et al., 2013). Typically, relatively young evolutionary lineages show wide zones of genetic admixture between them, while introgression between relatively old evolutionary lineages is restricted (Arntzen et al., 2014;Dufresnes et al., 2023;Kalaentzis et al., 2023;Wielstra et al., 2018Wielstra et al., , 2017. Many of these evolutionary lineages have recently been recognized or confirmed as distinct (cryptic) species (Díaz-Rodríguez et al., 2017;Dufresnes et al., 2020bDufresnes et al., , 2019Sequeira et al., 2020;van Riemsdijk et al., 2022;Wielstra and Arntzen, 2016). ...

... Our current understanding of using sounds in turtles is mainly in the hatching context. However, turtles are long-lived animals and hatching occurs on beaches and only takes a small portion of their life history; their majority of lives are underwater [82]. Moreover, the energy budget for developing sensory systems is supposed to be limited [83]. ...

... Typically, relatively young evolutionary lineages show wide zones of genetic admixture between them, while introgression between relatively old evolutionary lineages is restricted (Arntzen et al., 2014;Dufresnes et al., 2023;Kalaentzis et al., 2023;Wielstra et al., 2018Wielstra et al., , 2017.

... Moreover, this is a parameter essential to infer the life history traits of a species and to compare it to other species (de Buffrénil et al., 2021;Ma et al., 2022). In this context, skeletochronology is an effective and reliable method for estimating the growth and age of many amphibian species as the growth of amphibians is not independent of environmental conditions (Guarino et al., 2019;Üzüm et al., 2020). In addition, the method can be also applied to animals such as mammals (Nacarino-Meneses et al., 2016), lizards (Beşer et al., 2019), turtles (Guarino et al., 2020), and even fossils (de Buffrénil et al., 2021). ...

... We then used an ordination null test of PCA-environment in E-space to assess whether these closely related species occupy habitats that are more similar or more different than expected based on background environmental divergence. These results provide a multidimensional and comprehensive picture of niche variation within Ablepharus species when combined with phylogeographic relationships (Bozkurt & Olgun, 2020;Karamiani et al., 2021;Mirza et al., 2022;Poulakakis et al., 2005Poulakakis et al., , 2013Skourtanioti et al., 2016). Furthermore, recent conservation efforts and future research into the impacts of climate change on biodiversity depend on a knowledge of the primary ecological restrictions on species distribution (Aguirre-Gutiérrez et al., 2015). ...

... Bu zengin tür çeşitliliğin araştırılması için 19. yüzyılın başlarından günümüze kadar hem bölgesel hem de türlere yönelik pek çok araştırma yapılmıştır [5][6][7][8][9][10][11][12][13][14][15][16]. Bu çalışmalar, mevcut türlerin taksonomisinin yanında ekolojisi, yayılışı ve korunması açısından önemli katkılar sağlamıştır. ...

... Although aging has hitherto been considered a common feature in organisms, increasing empirical data indicate that some organisms have substantial resistance to aging process (Schaible et al., 2015). In salamanders, three species of Salamandridae (Lyciasalamandra fazilae, Salamandra salamandra, and S. perspicillata) are known to show only negligible aging (Cayuela et al., 2019). ...

... An amphibian case that would benefit from increased phylogenetic resolution concerns the Near Eastern banded newts, genus Ommatotriton (Fig. 1). Limited genetic and morphological markers (Bülbül and Kutrup, 2013;Üzüm et al., 2019;van Riemsdijk et al., 2017) suggest that this genus comprises three species: the Anatolian banded newt O. nesterovi (Litvinchuk et al., 2005), the Caucasian banded newt O. ophryticus (Berthold, 1846) and the southern banded newt O. vittatus (Gray, 1835). This species radiation arose in a relatively short timeframe, a relatively long time ago (c. 25 Ma;van Riemsdijk et al., 2017): conditions under which phylogeny reconstruction is notoriously difficult (Degnan and Rosenberg, 2006;Philippe et al., 2011;Whitfield and Lockhart, 2007). ...

... Genome-scale data are becoming readily available for newts (Rancilhac et al., 2021) and have already been successfully applied for species delineation in related newt genera Pabijan et al., 2017;Wielstra et al., 2018), also in combination with exploring potential ecological (Wielstra et al., 2012;van Riemsdijk et al., 2017) and morphological differentiation (Gerlach and Fahrbach, 2016;Üzüm et al., 2019). A phylogenomic study is required to clarify the evolutionary significance of the tremendous mitochondrial diversity in the alpine newt. ...

... In the long-lived population, the annual survival rate remains high during the entire lifetime of a cohort suggesting that there is no decrease of survival with increasing age. In agreement with a study on palearctic salamanders (Cayuela et al., 2019b), we conclude that senescence is negligible in the variation of annual survival rates confirming prediction 2. ...
