The existence of critical thresholds is important for many management and conservation issues, but these thresholds suggest that data are required at spatial scales that are specific to the dispersal characteristics of the simulated population.

Book 1991 threats to the sustainability of ecosystems. The effects these changes may have on the environment have lead governments and sCientists to make predictions as to how soon changes might occur, where, and with what impact for large and small regions of the Earth. Along with this concern for change in

Climatic Constraints and Issues of Scale Controlling Regional Biomes,biomes, as well as spatial changes in the boundaries of biomes. The boundaries, or ecotones, between biomes have been suggested as potentially sensitive areas to climatic change and therefore useful for monitoring change. Regional gradients of vegetation habitat size and variability are explored for

Simulation of the Scale-Dependent Effects of Landscape Boundaries on Species Persistence and Disper dispersal of populations through heterogeneous landscapes. Movement was simulated on randomly generated landscapes and on forested landscapes digitized from aerial photographs. Simulation results indicated that population abundances will change suddenly near the critical threshold in habitat connec
