摘要

摘要-我们报告了2008年和2009年在黑河口国家野生动物保护区产卵的16个鳄龟巢的成功产卵情况。我们将每个离合器分成2部分用于现场和实验室孵育。野外部分受到保护，不受哺乳动物的掠夺。对于每一个巢，我们都报告了打桩和孵化的成功。总成功率为55.9%，总孵化成功率为47.7%。在实验室的孵化成功率为85.8%。野外和实验室孵化成功率差异的原因包括巢环境中的非生物和生物因素，如洪水、温度和无脊椎动物捕食者。

Nest Success of Alligator Snapping Turtles (Macrochelys temminckii) in Louisiana, with Comments on Sources of Mortality

Abstract - We report nest success for 16 Alligator Snapping Turtle nests oviposited at Black Bayou Lake National Wildlife Refuge in 2008 and 2009. We split each clutch into 2 portions for field and laboratory incubation. The field portion was protected from mammalian depredation. For each nest, we report both pipping and hatching success. Our total observed levels of pipping and hatching success were 55.9% and 47.7%, respectively. We obtained a hatching success rate of 85.8% in the lab. Reasons for the difference in hatching success between the field and lab included both abiotic and biotic factors in the nest environment, such as flooding, temperature, and invertebrate predators.

期刊介绍： The Southeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the southeastern portion of North America, roughly bounded from North Carolina south to Florida, west to Texas, north to Oklahoma, and east back to North Carolina. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion.
