Abstract
Abstract - Understanding population demographics of Macrochelys temminckii (Alligator Snapping Turtle) requires long-term studies. Most previous studies do not provide demographic population data. We conducted a mark–recapture study of M. temminckii inhabiting Buffalo Bayou in Harris County, TX, from October 2016 through August 2021. We captured 110 unique individuals during 465 trap nights and recorded 45 recaptures. We generated 8 biological metrics. Capture per unit effort varied from 0.267 to 0.547 turtles per trap-night, the population estimate was 173 turtles (95% CI:138–250), the sex ratio was 1.00 M:1.28 F, and density and biomass estimates were 4.43 turtles/river km and 89.9 kg/km, respectively. Given that anthropogenic risks to this urban population may increase, continued monitoring and research is warranted.
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.
