Abstract:

A discrete mathematical model was developed to study the population dynamics after a time-varying environmental disaster (R4.x261.000:0008). A 5-stage-structure matrix includes parameters for stage-specific survival and transition rates, as well as annual fecundity. This model can be used to examine the sensitivity and elasticity of the model, as well as demographic and environmental stochasticity, and many others.

Purpose:

This model was developed to eventually utilize passive acoustic detections of marine mammals to study population dynamics in the northern Gulf of Mexico.

Theme Keywords:

Stochasticity, population demographics, recovery probability
