Conservation in insular parks: Simulation models of factors affecting the movement of animals across park boundaries

摘要: Abstract Many parks represent insular areas of habitat and the movement animals across park boundaries can be critical to wildlife populations. I use computer simulation models in order analyse factors affecting density patches (Buechner, 1987b; Stamps et al. , 1987; press). The results suggest that perimeter: area ratios edge permeability parks, appearance stopping patterns preferences moving animals, relative size dispersal sinks source pools all potentially influence direction magnitude boundaries. scientists interested reserve design n consider other than just potential sites, particularly ratios. simulations also suggests a strategy for solving some types conservation control problems by manipulating or pools: (1) identify which practically altered given situation, (2) evaluate those estimate their current levels, (3) focus on factor is nearest lower end its range values.
