Publisher Summary This chapter reviews studies that have analyzed the effects of local
weather and large-scale climate phenomenon on fluctuations in the size of bird populations …

Harvest policies use control rules and associated policy parameters to dictate how fishing
mortality or catch and yield levels are determined, and are necessary for rational …

Anthropogenic factors constitute the primary deterministic causes of species declines,
endangerment and extinction: land development, overexploitation, species translocations …

This book offers a concise but comprehensive introduction to desert ecology and adopts a
strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis …

General definitions of demographic and environmental variances as well as demographic
covariance are given from first principles. The sum of the environmental variance and the …

We consider a tri-trophic stochastic food-chain model with harvesting. We first establish
critical values between persistence in mean and extinction for each species. The results …

Diffusion models of stochastic population dynamics, including both demographic and
environmental stochasticity, can be transformed to a scale with isotropic noise. On this scale …

Commercially important species often are overexploited, and many endangered mammals
and birds are threatened by hunting and international trade. To sustain biological resources …

Population cycling is a widespread phenomenon, observed across a multitude of taxa in
both laboratory and natural conditions. Historically, the theory associated with population …

We obtain the optimal harvesting plan to maximize the expected discounted number of
individuals harvested over an infinite future horizon, under the most common (Verhulst …
