How Do Any Species Persist? Lessons for Conservation Biology

How Do Any Species Persist? Lessons for Conservation Biology Abstract: Recent reformulation of the birth‐and‐death process model to include the effects of environmental variation on stochastic demography presents a pessimistic view of the prospects for persistence of small populations. The models indicate that modest increases in population size, or in the mean (positive) growth rate of the population, do not dramatically increase the mean persistence time. The key to long‐term persistence seems to lie in reducing the variance in the population growth rate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Conservation Biology Wiley

Abstract

Abstract: Recent reformulation of the birth‐and‐death process model to include the effects of environmental variation on stochastic demography presents a pessimistic view of the prospects for persistence of small populations. The models indicate that modest increases in population size, or in the mean (positive) growth rate of the population, do not dramatically increase the mean persistence time. The key to long‐term persistence seems to lie in reducing the variance in the population growth rate.
