Abstract
Recent work on the dynamics of species living in fragmented landscapes has produced much information on patterns of habitat patch occupancy in a wide range of organisms. Building on an elementary Markov chain m odel of patch occupancy, a family of incidence-function models can be constructed for particular kinds of metapopulations. These models can be parameterized with field data on patch occupancy, and the models ca n be used to make quantitative predictions about specific metapopulati ons. This approach provides a potentially powerful tool for the manage ment of reserve networks and species living in fragmented landscapes.
