Age and Growth of the Green Toad, Bufo viridis (Laurenti, 1768) from an Island and a Mainland Population in Giresun, Turkey

Life history traits in Bufotes variabilis (Pallas, 1769) from 2 different altitudes in Turkey

“…In addition, a significant positive correlation was found between both body size and mass, and age and body mass, except in the males of the Adana population. Both Castellano et al (1999) and Kutrup et al (2011) found significant differences between island and mainland populations of B. variabilis, indicating that island adults were on average heavier than mainland adults. In the present study, the average body mass of the highland population was significantly higher than that of the lowland population.…”

“…In general, amphibians attain sexual maturity after having reached a certain minimum size but a variable age (Gibbons and McCarty, 1984;Hemelaar, 1986;Ryser, However, in the study by Kutrup et al (2011), it was reported as 2-3 years for both populations. Similar to the findings for our high-altitude population, Gokhelashvili and Tarkhnishvili (1994) determined age at sexual maturity as 2-3 years for males and 3-4 years for females in a Georgian population (1200 m a.s.l.).…”

“…Maximum lifespan was 5 and 8 years for Armenian and Iranian populations, respectively (Ledentsov and Melkumyan, 1986;Ashkavandi et al, 2012). The single demographic study (Kutrup et al, 2011) on Bufotes variabilis in Turkey was conducted on island (Giresun Island, 0-30 m a.s.l.) and mainland (Giresun Province, 20-100 m a.s.l.)…”

Impact of various ecological parameters on the life‐history characteristics of Bufotes viridis sitibundus from Turkey

“…We also arrived on a similar number in this study (Söğütlü population). In other populations (Ashkavandi et al, 2012; Gokhelashvili & Tarkhnishvili, 1994; Kutrup et al, 2011) the longevity varied between and 6–10 years. The Italian (Zucchea) population had the highest mean age of 7.00 years, while the Turkish (Söğütlü) population had the lowest mean age of 2.50 years (Table 2).…”

“…In this study, 308 variable toads from eight different populations in Turkey were investigated using a skeletochronological method to determine the age and growth rate. Previous studies investigating the age structure and morphology of variable toad populations are limited (Ashkavandi et al, 2012; Castellano et al, 1999; Gokhelashvili & Tarkhnishvili, 1994; Kutrup et al, 2011; Ledentsov & Melkumyan, 1986; Sinsch et al, 2007). The findings of this study demonstrate that the different populations of B. v. sitibundus show both similarities and differences with respect to various aspects (Table 2).…”
