Abstract

Abstract - Alligator snapping turtles (genus Macrochelys) are the largest freshwater turtles in North America. Despite strong interest in their conservation, we still lack a comprehensive understanding of their natural history, including behaviors associated with terrestrial activity. We reviewed the literature and solicited unpublished observations of terrestrial movements of these highly aquatic turtles. We compiled 206 observations of terrestrial activity from 9 states. The majority of observations were associated with nesting behavior. Observations expanded our knowledge regarding the spatial extent and timing of terrestrial movements and the nesting season. In addition, we compiled observations of terrestrially foraging animals, as well as males and juveniles traveling overland and crossing roads. Collectively, this information clarifies the extent of terrestrial movement by Macrochelys, behaviors that should be considered in conservation plans.

大螯虾的筑巢出现和其他陆地运动(螯虾目:螯虾科)

鳄鳄龟(Macrochelys属)是北美洲最大的淡水龟。尽管人们对它们的保护有着浓厚的兴趣，但我们对它们的自然历史，包括与陆地活动相关的行为，仍然缺乏全面的了解。我们回顾了文献，并征求了未发表的关于这些高度水生海龟陆地运动的观察结果。我们收集了来自9个州的206份陆地活动观测资料。大多数观察结果都与筑巢行为有关。观察扩大了我们对陆地活动的空间范围和时间以及筑巢季节的认识。此外，我们还收集了陆地觅食动物的观察结果，以及在陆地上旅行和穿越道路的雄性和幼年动物。总的来说，这些信息阐明了Macrochelys在陆地上移动的程度，这些行为应该在保护计划中加以考虑。

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.
