Stochastic intermittent perturbations to dynamical systems: rainfall and fires

In this talk, I will illustrate how plants respond to drought in drylands, and how wildfires will influence plant communities and their recovery in the Mediterranean basin. Both topics are of uttermost social and ecological relevance, given the severity of the effects climate change is predicted to have in global and Mediterranean drylands. Technically, both fires and rainfall events can be represented as pulse perturbations in dynamical systems. Rainfall is an intermittent input of water for the soil and plants. Plants are well adapted to the nonlinear input of water, which promotes survival and sustain biodiversity in drylands. Wildfires, in combination with climate change, can be shifting the recovery trajectory of Mediterranean forests to an alternative ecosystem state, namely an open shrubland, which is often an undesirable state from a human perspective.
