Abstract

Abstract Human (managerial) actions affect the survival probabilities of the keystone species of an ecological–economic system. In turn, the well-being of these keystone species translates into the well-being or the resilience of the underlying ecological–economic system. What are the theoretical connections between human actions, keystone species survival, and the resilience of ecological–economic systems? In this note, we construct a simple stochastic model to draw out the links between this trinity.
