Abstract

Abstract Broad variation in egg hatching success observed in gopher tortoise (Gopherus polyphemus) populations led us to investigate hatching success and other reproductive attributes within a unique, high-quality site in the eastern portion of the species' range. We documented use of a juvenile tortoise burrow as a nest site, a mean clutch size of 5.9 eggs, long oviposition-to-hatchling emergence times (96–128 d), and 73% hatching success for predator-protected eggs. Although consistent with previous reports of greater hatching success in eastern gopher tortoise populations than in western ones, hatching success at our eastern site was on the low end of values from other eastern populations, possibly reflecting above average rainfall during this study.

乔治亚州西南部戈弗龟的孵化成功和其他繁殖特性

摘要在地鼠龟（Gopherus polyphemus）种群中观察到的卵孵化成功率的广泛差异使我们在该物种东部的一个独特、高质量的地点研究了孵化成功率和其他繁殖属性。我们记录了使用幼年乌龟洞穴作为巢穴，平均窝卵大小为5.9个，产卵到孵化的出现时间很长（96-128天），捕食者保护的卵孵化成功率为73%。尽管与之前关于东部地鼠龟种群孵化成功率高于西部地鼠龟的报道一致，但我们东部地区的孵化成功率处于其他东部种群的低端，这可能反映了本研究期间高于平均水平的降雨量。

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.
