Rewilding complex ecosystems

Pleistocene rewilding, frankenstein ecosystems, and an alternative conservation agenda.

ecological processes lost in the Americas in the late Pleis-tocene, a little over 10,000 years ago, by rewilding, that is, by translocating a suite of large African and Asian vertebrates to the American continent. There is a strong evidence that the megafauna in the Americas at that time was driven to extinction by humans (Martin & Klein 1984), which caused the loss of many ecological interacti...

Detecting causality in complex ecosystems.

Identifying causal networks is important for effective policy and management recommendations on climate, epidemiology, financial regulation, and much else. We introduce a method, based on nonlinear state space reconstruction, that can distinguish causality from correlation. It extends to nonseparable weakly connected dynamic systems (cases not covered by the current Granger causality paradigm)....

Essays and Perspectives - Rewilding South American Landscapes Rewilding ecological communities and rewiring ecological networks

Rewilding encompasses management actions such as reintroductions and translocations with the purpose of restoring ecological processes and ecosystem functions that were lost when species were locally extirpated. The success of a species introduction is conditioned by multiple factors, in particular, ecological interactions. To predict the fate of the introduced population and the community-leve...
