Abstract

Conserving and managing an imperiled species, such as Testudo hermanni, requires information on population status and demographic traits. To acquire this information, we surveyed Hermann's tortoises, Testudo hermanni boettgeri, in European Turkey from April to October 2014–2016. We found 283 (135 males, 102 females, 45 juveniles, and 1 unknown) T. h. boettgeri at 34 locations. Of these sites, 29% included at least 1 individual. We found that females were larger and heavier (mean straight carapace length [SCL] = 175.4 mm, body mass = 1234.1 g) than males (SCL = 153.2 mm, body mass = 849.6 g). The age frequency had a normal Gaussian distribution with 11–15 yrs being the most common. Elevation at capture sites ranged from 22 to 380 m above sea level. Illegal overharvesting for the pet trade appears to have caused no reduction in body size.

土耳其东赫尔曼龟的分布、大小和人口统计

保护和管理一种濒危物种，如狐猴，需要关于种群状况和人口特征的信息。为了获得这些信息，我们于2014年4月至2016年10月在土耳其欧洲地区调查了Hermann's陆龟，Testudo hermanni boettgeri。在34个地点共发现283只(雄性135只，雌性102只，幼年45只，未知1只)。在这些站点中，29%包含至少1个个体。结果表明，雌性比雄性(SCL = 153.2 mm，体重= 849.6 g)体型更大、体重更重(SCL = 175.4 mm，体重= 1234.1 g)，年龄分布符合正态高斯分布，以11 ~ 15岁最为常见。捕获地点的海拔高度从海拔22米到380米不等。为宠物交易而非法过度捕捞似乎并没有导致体型的减少。

期刊介绍： Chelonian Conservation and Biology is a biannual peer-reviewed journal of cosmopolitan and broad-based coverage of all aspects of conservation and biology of all chelonians, including freshwater turtles, marine turtles, and tortoises. Manuscripts may cover any aspects of turtle and tortoise research, with a preference for conservation or biology. Manuscripts dealing with conservation biology, systematic relationships, chelonian diversity, geographic distribution, natural history, ecology, reproduction, morphology and natural variation, population status, husbandry, community conservation initiatives, and human exploitation or conservation management issues are of special interest.
