摘要

摘要2013年9月至2014年9月，在马来西亚槟城岛对绿龟(Chelonia mydas)巢穴进行微生境调查，通过对同一个体(n = 9)筑巢的成功巢(n = 43)和流产巢(n = 106)进行监测，探讨影响绿龟筑巢成功的关键因素。砂粒大小对绿海龟筑巢成功率的影响显著，表明砂粒大小< 1 mm的地点绿海龟倾向于中止筑巢。此外，在表层砂温低于32.95°C的条件下，筑巢成功。

Importance of Sand Particle Size and Temperature for Nesting Success of Green Turtles in Penang Island, Malaysia

Abstract The microhabitats of green turtle (Chelonia mydas) nests were investigated to identify key factors influencing nesting success by monitoring both successful nests (n = 43) and aborted nests (n = 106) created by the same individuals (n = 9) from September 2013 to September 2014 on Penang Island, Malaysia. The effect of sand particle size on nesting success was significant, suggesting that green turtles tend to abort nesting at sites with sands of particle sizes < 1 mm. In addition, nests were successful at superficial sand temperatures less than 32.95°C.

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.
