| Abstract |
|
The home ranges and habitat selection of Blanding’s turtles (Emydoidea blandingii) were examined at an area known as the Weaver Dunes, located in Wabasha County, Minnesota as part of an ecological survey of the species. 38 individual Blanding’s turtles (23 females, 12 males, 3 juveniles) were radio monitored from April 15 th, 1999 to April 1 st , 2000 in an effort to better understand particular characteristics of the species’ spatial behavior at this specific locale. Of these 38 radio marked turtles, home range and habitat selection analyses were performed on 24 individuals (16 females, 8 males) with the most complete telemetry records in ArcView GIS. Home ranges were calculated using the Minimum Convex Polygon (MCP), Bivariate Normal Density Kernel (BNK), and Poly-Buff (PB) methods. Home range sizes did not vary significantly between sexes, regardless of method, but were significantly different between separate study-site subsections. There was also a significant difference between the home ranges calculated with the Poly-Buff versus those calculated with the other two home range methods. The Neu habitat selection model was used to statistically analyze preference/avoidance of particular land cover types for the entire radio sampled population, males, females, and inhabitants of 2 of the 3 study-site subsections, resulting in turtles selecting for Emergent, Submergent, Woody Terrestrial, and Submergent-Rooted Floating Aquatic habitats.
