SPATIALLY EXPLICIT POPULATION MODELS:
CURRENT FORMS AND FUTURE USES
Abstract. Spatially explicit population models are becoming increasingly useful
tools for population ecologists, conservation biologists, and land managers.
Models are spatially explicit when they combine a population simulator with a
landscape map that describes the spatial distribution of landscape features. With
this map, the locations of habitat patches, individuals, and other items of interest
are explicitly incorporated into the model, and the effect of changing landscape
features on population dynamics can be studied. In this paper we describe the
structure of some spatially explicit models under development and provide
examples of current and future research using these models. Spatially explicit
models are important tools for investigating scale-related questions in population
ecology, especially the response of organisms to habitat change occurring at a
variety of spatial and temporal scales. Simulation models that incorporate
real-world landscapes, as portrayed by landscape maps created with geographic
information systems, are also proving to be crucial in the development of
management strategies in response to regional land-use and other global change
processes. Spatially explicit population models will increase our ability to
accurately model complex landscapes, and therefore should improve both basic
ecological knowledge of landscape phenomena and applications of landscape
ecology to conservation and management.
