Sensitivity analysis of the recovery time for a population under the impact of an environmental disturbance
Abstract Wildlife populations are often affected by natural or artificial disasters that reduce their vital rates leading to drastic fluctuations in population dynamics. We use a stage‐structured matrix model to study the recovery process of a population given an environmental disturbance. We focus...
