摘要: The relationships between life history characteristics and broad-scale patterns of species abundance were investigated with a model that simulates the dispersal populations through heterogeneous landscapes. Movement was simulated on randomly generated landscapes forested digitized from aerial photographs. Simulation results indicated population abundances will change suddenly near critical threshold in habitat connectivity as predicted percolation theory. existence thresholds is important for many management conservation issues, but these suggest data are required at spatial scales specific to population.
