Reproductive ecology of the endangered Beal's-eyed turtle, .

The Beal's-eyed turtle () is endemic to southeastern China and endangered due to poaching and habitat loss. Knowledge of ecology is lacking and this study provides baseline information of its reproduction in a natural environment. We studied the reproductive ecology of using X-ray, spool-and-line tracking, and direct observation.

Melanin deposition ruled out as cause of color changes in the red-eared sliders (Trachemys scripta elegans).

Animal coloration primarily depends on the presence of pigments and the mixing ratio of eumelanin and pheomelanin. The color of red-eared slider's carapace varies with age, from an olive green to a yellow green, and then to a yellow brown in juveniles, generally. The purpose of the present study was to investigate whether this color change is related to the difference in melanin expression.
