Several recent studies have shown that amphibian populations may exhibit high genetic subdivision in areas with recent fragmentation and urban development. Less is known about the potential for genetic differentiation in continuous habitats. We studied genetic differentiation of red-backed salamanders (Plethodon cinereus) across a 2-km transect through(More)
Roads can fragment animal populations by reducing gene flow, which can lead to drift and the loss of genetic diversity. One of the principle signatures of reduced gene flow is increased genetic differentiation in isolated populations, and evidence that roads contribute to such differentiation has been reported for several species. We used microsatellites to(More)
Most studies of animal behaviour are based on direct observations of behaviour in a natural or laboratory context. While the potential for observation biases has often been discussed, there have been few quantitative analyses of the kinds of biases that may affect behavioural data. We used multiple observers of aggression and foraging behaviour in(More)
