Abstract
The patchy distribution of habitats in landscapes determines how populations are organized in local breeding groups and how frequently individuals move between these groups. This landscape structure and these life-history traits determine the population structure and the conservation problems faced by endangered species. In fragmented landscapes, isolated populations in small patches face a number of problems ranging from loss of genetic diversity to edge effects. Habitat heterogeneity occurs at multiple spatial scales and influences different aspects of population dynamics.
