摘要:
The few descriptive accounts of populations of the common snapping turtle, Chelydra s. serpentina, uniformly indicate a low density and an equal sex ratio. Capture-recapture data for a 0.81 ha pond revealed estimates of densities an order of magnitude greater than previous accounts. Differential use of space by different sized turtles was indicated. Adult ♂ ♂ were larger and more abundant than adult ♀ ♀. The differences between our results and other accounts indicate that a "typical" description of snapping turtle population parameters does not adequately express the variation which may exist between populations. This variation may, in fact, be confounding in studies of variables involved in population dynamics.
