Movement and Spatial Dispersion of Sistrurus catenatus and Heterodon platirhinos: Implications for Interactions with Roads

摘要: Abstract The ability to predict the effects that new or modified roads will have on species populations of conservation interest is critically important protection efforts. We documented patterns movement and spatial dispersion two sympatric snake by radiotracking 34 Eastern Massasaugas (Sistrurus catenatus) 13 Hog-Nosed Snakes (Heterodon platirhinos) over four years. differed substantially in their movements (frequency, rate, tortuosity, distance) ensuing dispersion. Regardless species, males were more vagile than female conspecifics during mating season. primary factors hypothesized generated interspecific differences foraging mode, system, reproductive mode. By combining our understanding how these snakes used space with knowledge natural history ecology, we examined which attributes ecology might render S. catenatus H. platirhino...
