Ecological Risk Assessment Based on Stochastic Age-Structured Models of Population Growth

Source

A method is developed to evaluate the risk of a population crossing a preassigned critical level in a given period of time. The method is based on the stochastic age-structured model of population dynamics. The two-step process is suggested. The first step constructs the “effective” one-dimensional model with the autocorrelated noise term reflecting the underlying multidimensional process. The second step solves the first passage time problem in a one-dimensional context.
