In this study, we used the skeletochronology method to estimate various growth parameters, such as age structure, minimum and maximum life span, age of sexual maturity, and the relationship between body size and weight of eight different populations of the variable toad, Bufotes viridis sitibundus, in Turkey. Further, we determined the relationship between these parameters and ecologic factors using the partial Mantel test. A significant difference was found among the populations with respect to age, body size, and body weight in both males and females. On average, the maximum life span was recorded as 10 years for males and 11 years for females. In the studied populations, the average age of sexual maturity ranged between 2 and 4 years for both sexes. Sexual dimorphism in terms of snout-vent length (SVL) was not observed between males and females in all the populations. Toads from the higher altitudes tended to be significantly larger, older, and heavier than those from lower altitudes. We concluded that altitude and temperature have an impact on the growth rate, body size, and body mass.
在这项研究中，我们使用骨骼年代学方法来估计各种生长参数，如年龄结构、最小和最大寿命、性成熟年龄，以及体型和体重之间的关系，研究了土耳其八种不同种群的变色蟾蜍（Bufotes viridis sitibundus）。此外，我们还使用偏 Mantel 检验来确定这些参数与生态因素之间的关系。结果发现，不同种群之间的年龄、体型和体重在雌雄两性之间存在显著差异。平均而言，雄性的最大寿命为 10 年，雌性为 11 年。在所研究的种群中，雌雄两性的性成熟年龄平均在 2 到 4 岁之间。在所有种群中，雄性和雌性的吻肛长（SVL）没有表现出性别二态性。来自高海拔地区的蟾蜍往往比来自低海拔地区的蟾蜍体型更大、年龄更大、体重更重。我们得出结论，海拔和温度对生长速度、体型和体重有影响。
