Distribution of woodland amphibians along a forest fragmentation gradient

  • 1 August 1998
Correlations between species' biological traits and their fragmentation tolerance imply that low density, population variability, and high mobility coupled with restricted habitat needs predispose woodland amphibians to local extinction caused by habitat fragmentation. Expand
Wetland Loss and Biodiversity Conservation

  • 1 February 2000
Abstract: Most species of wetland-dependent organisms live in multiple local populations sustained through occasional migration. Retention of minimum wetland densities in human-dominated landscapesExpand
Estimating the effects of road mortality on turtle populations
Road mortality is suspected to have contributed to widespread population declines in turtles in the United States, a country with exceptionally high turtle diversity. We examined the issue through aExpand
Amphibian Movements in Response to Forest Edges, Roads, and Streambeds in Southern New England
If management of landscape linkages is to be promoted as a means of conserving amphibian populations, it must be demonstrated that amphibian dispersal does not occur independently of ecosystem edgesExpand
Impacts of road deicing salt on the demography of vernal pool-breeding amphibians.
It is argued that efforts to protect local populations of A. maculatum and R. sylvatica in roadside wetlands should, in part, be aimed at reducing application of road salt near wetlands with high conductivity levels. Expand
Effects of Roads on the Structure of Freshwater Turtle Populations
High road density was associated with male-biased sex ratios in painted turtles and snapping turtles, whereas turtle morphology and abundance were not associated with road density, and disproportionate road mortality of females on nesting migrations is the most likely cause of skewed sex ratios.

Road-Crossing Structures for Amphibians and Reptiles: Informing Design through Behavioral Analysis
Through a series of behavioral choice experiments, results indicate that for particular organisms, specific variables did seem to influence patterns of choice in the design of behaviorally palatable crossing structures. Expand
Relative vulnerability of female turtles to road mortality
It is concluded that female turtles are indeed more likely to cross roadways than are males, which may explain recently reported skewed sex ratios near roadways and signify eventual population declines as females are differentially eliminated. Expand
Lion‐Human Conflict in the Gir Forest, India
Prohibiting lion baiting for tourist shows, consolidation of reserve boundaries, and implementation of a more equitable and simpler system for compensating villagers for livestock destroyed by lions could provide short-term alleviation of lion-human conflict in the region. Expand
