Early warning signals of extinction in a deteriorating environment
Host: Ilkka Hanski
Abstract: Recent studies have shown that tipping points in banking system failures, earth and atmospheric climate shifts, and physiological processes are all anticipated by characteristic statistical phenomena. Many (but not all) such “signatures of tipping points” are the result of critical slowing down that coincides with a bifurcation in the mathematical description of the system. Although not previously studied in this respect, standard models of population dynamics exhibit the relevant class of bifurcations and therefore should exhibit these phenomena prior to the crossing of a macroscopic tipping point. In this work, we show some of the conditions under which such early warning signals may be observed and present experimental work documenting the phenomena in a model system.
