摘要

摘要-短吻鳄鳄龟(Macrochelys temminckii)是一种受保护的物种，由于过去的商业捕捞用于消费。路易斯安那州北部最初在20世纪80年代进行了调查，但调查数据没有汇编和公布。近40年后，我们重新调查了该地区，以验证历史数据，并提供鳄鳄鳄龟分布的当前数据。从20世纪80年代开始，我们提供了从路易斯安那州17个教区收集的300只鳄龟的人口统计数据。从2018年到2020年，我们从19个诱捕点捕获并测量了62只鳄鳄龟。我们建议继续在路易斯安那州进行调查和监测工作，以跟踪商业收获后的种群数量。

Status and Distribution of Alligator Snapping Turtles (Macrochelys temminckii) in Northern Louisiana

Abstract - The Alligator Snapping Turtle (Macrochelys temminckii) is a species of conservation concern across its range due to past commercial harvest for consumption. Northern Louisiana was originally surveyed in the 1980s, but the survey data were not compiled and published. After almost 40 years, we resurveyed the region to validate the historic data as well as provide current data on the distribution of Alligator Snapping Turtles. From the 1980s, we provide demographic data for 300 Alligator Snapping Turtles collected from 17 Louisiana parishes. From 2018–2020, we captured and measured 62 Alligator Snapping Turtles from 19 trapping sites. We recommend continued surveying and monitoring efforts in Louisiana to track populations during the post-commercial–harvest period.

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.
