Ecosystem Stability and the Distribution of Community Matrix Eigenvalues.

摘要

A definition or measure of ecological stability is introduced which is advantageous in that it may be empirically accessible and in that it relates to practical concerns in situations of environmental stress. It is shown how this measure can be analyzed,for an arbitrary system described by a community matrix,by model-independent mathematical methods. The relationship between the stability of any such system and both the distribution of community matrix eigenvalues and the pattern of pathway linkages is discussed. (ERA citation 03:005166)
