摘要：
We study diffusive logistic growth with immigration for a habitat surrounded by a hostile environment. The focus of our interest is the effect of immigration on the critical habitat length required for survival of the population. As expected, we find that this is reduced when immigration occurs. We also briefly consider the much simpler case where both immigration and emigration take place in an isolated habitat. (c) 2005 Elsevier Ltd. All rights reserved.
