Prediction and Mitigation of Tipping Points in Living Systems

Many natural systems can undergo sudden, large and often irreversible changes under the influence of small stochastic perturbations. Such qualitative sudden changes in the structure and function of a system are known as regime shift or critical transition. Critical transitions occur as a consequence of gradual changes in a system or an environmental parameters and unprecedented changes in environmental conditions project high importance on rate of change of theses parameters. The key objective is to study regime shift in various bi-stable biological systems. Well known examples of regime shifts in complex systems include: collapse of ecosystems (ecology), crash of markets in global finance (finance), systemic failures such as epileptic seizures (biology), and Arctic sea ice melting (climate). Each of these shifts has the potential to invoke serious and harmful consequences for environment as well as human well-being. Therefore, understanding the mechanisms of regime shifts and predicting them using early warning signals (EWS) are important issues due to the potential application in management and prevention of catastrophes in complex nonlinear systems.
