| Abstract |
|
The painted turtle (Chrysemys picta) is commonly found throughout a variety of habitats, but availability of food and presence of basking sites may affect the habitat preferences and thus the population density. During the nesting season, female painted turtles must also choose habitats that provide them with suitable nesting sites within close proximity. Nesting preferences were investigated through a road survey of nesting painted turtles, and habitat preferences were tested by trapping turtles at three different habitat types (lakes, creeks, and beaver ponds). I found that, although turtles were not choosing aquatic habitat types preferentially. Their nesting sites along roads were located significantly farther from wetland habitats than by chance alone. Results for the trapping data showed no significant differences in relative abundance, size, or gender across habitat types. My results suggest that turtles on the UNDERC property are not preferentially choosing among possible aquatic habitats based on either their suitability for habitation or their distance from a potential nesting site.
