Abstract

Abstract - We investigated nesting behavior and terrestrial activity in a captive population of Macrochelys temminckii (Alligator Snapping Turtle) housed outdoors in semi-natural environmental conditions in Oklahoma. The nesting season lasted from 12 May to 15 June 2012, and turtles were most active between the hours 2300–0300. Nesting duration averaged 182.5 min. Over 50% of nest construction time was spent excavating the cavity, whereas covering the eggs accounted for ∼28% of the total duration. Individual females averaged 25 non-nesting emergences before successfully depositing eggs. Terrestrial activity was positively correlated with increasing average nighttime temperature. We found thermal profiles generated by temperature data loggers affixed to females useful for studying terrestrial activity during nesting.

圈养鳄鳄龟种群的筑巢行为和生态

摘要/ Abstract摘要:本文研究了俄克拉何马州半自然环境下圈养的巨鳄鳄龟(Macrochelys temminckii)的筑巢行为和陆地活动。筑巢季节为2012年5月12日至6月15日，海龟在2300-0300时最活跃。筑巢时间平均为182.5分钟。超过50%的筑巢时间花在挖掘洞上，而覆盖鸡蛋则占总时间的28%。在成功产卵之前，每只雌性平均有25次不筑巢的出现。陆地活动与夜间平均气温升高呈正相关。我们发现附着在雌性身上的温度数据记录仪产生的温度曲线对研究筑巢期间的陆地活动很有用。

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.
