Movement And Macrohabitat Selection Of The Eastern Massasauga In A Fen Habitat, John Marshall, Jr., Jennifer Manning, Bruce Kingsbury
Bruce A Kingsbury Ph.D.
The eastern massasauga, Sistrurus c. catenatus, is a small rattlesnake threatened with extirpation throughout its range. Massasaugas occur in a variety of habitats and adequate knowledge of their natural history at local scales is essential for effective management. We used radiotelemetry to document patterns of movement and macrohabitat selection of massasaugas in a fen environment, an important, but understudied, habitat. Based on both 100% minimum convex polygons and 95% kernel density, seasonal home ranges of males were larger than those of nongravid females which, in turn, were larger than those of gravid females. Activity center estimations followed the same …
Wetland Complexes And Upland-Wetland Linkages: Landscape Effects On The Distribution Of Rare And Common Wetland Reptiles, Omar Attum, Y. Lee, J. Roe, Bruce Kingsbury
Wetland Complexes And Upland-Wetland Linkages: Landscape Effects On The Distribution Of Rare And Common Wetland Reptiles, Omar Attum, Y. Lee, J. Roe, Bruce Kingsbury
Bruce A Kingsbury Ph.D.
We used landscape ecology concepts to test the importance of upland–wetland linkages on the distribution of two common wetland species, the northern watersnake Nerodia sipedon sipedon and midland painted turtle Chrysemys picta marginata, and two rare wetland species, the copper-bellied watersnake Nerodia erythrogaster neglecta and Blanding's turtle Emydoidea blandingii. We tested if connectivity (proximity to other wetlands), connectivity quality (wetland distance to roads and forest area within 30, 125, 250, 500 and 1000 m of the wetland), and patch size (wetland size and shoreline length) affected the distribution of these four species. Our results show that both common species were …
