Stage structure alters how complexity affects stability of ecological networks
V. H. W. Rudolf, Kevin D. Lafferty
2011, Ecology Letters (14) 75-79
Resolving how complexity affects stability of natural communities is of key importance for predicting the consequences of biodiversity loss. Central to previous stability analysis has been the assumption that the resources of a consumer are substitutable. However, during their development, most species change diets; for instance, adults often use different...
