摘要
Even when environments deteriorate gradually, ecosystems may shift abruptly from one state to another. Such catas營養級 shifts are difficult to predict and sometimes to reverse (so-called hysteresis). While well studied in simplified contexts, we lack a general understanding of how catas營養級 shifts spread in realistically spatially structured landscapes. For different types of landscape structures, including typical terrestrial modular and riverine dendritic 網絡s, we here investigate landscape-scale stability in meta族群s whose patches can locally exhibit catas營養級 shifts. We find that such meta族群s usually exhibit large-scale catas營養級 shifts and hysteresis and that the properties of these shifts depend strongly on the meta族群 spatial structure and on the 族群 dispersal rate: an intermediate dispersal
