We consider stochastic growth models to represent population subject to catastrophes. We analyze whether dispersion is a good strategy to increase a population viability. We find out that the answer depends on the effect of a catastrophic event, the spatial constraints of the environment and the probability that each individual exposed to the catastrophe survives when a disaster strikes.
Fábio Machado is Professor at the Statistics Department, University of São Paulo, Brazil. His research interests lie in theoretical and applied aspects of probability and stochastic processes, in particular those that can be seen from interacting particle systems, random walks and percolation point of view.
