摘要: We develop methods for quantifying habitat connectivity at multiple scales and assigning conservation priority to patches based on their contribution connectivity. By representing the mosaic as a mathematical "graph," we show that percolation theory can be used quantify from empirical landscape data. Our results indicate of landscapes is highly scale dependent, exhibiting marked transition characteristic distance varying significantly organisms with different dispersal behavior. More importantly, sensitivity importance pattern also peaking associated transition. In addition, analysis allows us identify critical "stepping stone" that, when removed landscape, cause large changes in
