Stability and diversity of ecological communities

摘要: MAY1 drew an analogy between large randomly connected cybernetic networks2,3 and ecosystems. His analysis of stability criteria for such networks seems to contradict the traditional ecological hypothesis that ecosystem diversity contributes functional stability4–7. May's analytical solution matrices in which each element by itself is stable showed that1 “too rich a web connectance or too average interaction strength leads instability. The larger number species, more pronounced effect”. As elements matrix increases, transition region instability becomes increasingly narrow1–3. Thus, complex system perched near this subject self-generating catastrophe upon only minor modification parameters. If these models are applicable real ecosystems, they obviously have immense implications resource management as well theory. I report here application conclusion system.
