Modeling spatial distribution of amphibian populations: a GIS approach based on habitat matrix permeability

  title={Modeling spatial distribution of amphibian populations: a GIS approach based on habitat matrix permeability},
  author={N. Ray and Anthony Lehmann and Pierre Joly},
  journal={Biodiversity & Conservation},
Predictions of occurrence of two amphibian species, the common toad and the alpine newt, were made using information on land use surrounding breeding ponds. A geographical information system (GIS) was used to compile a landuse map, from which permeability estimates (friction) were derived. Potential migration zones based on friction and maximum migration distance were then modeled. Contacts between several migration zones suggest the potential for migration between ponds by adult individuals… CONTINUE READING
