Abstract

This book provides an overview of the importance of research on relict species and presents conclusions and findings on the conservation of these species. There are relict species and populations from nearly all plant and animal groups and they contribute substantially to biodiversity across the globe. Current diversity patterns are influenced by both historic and recent ecological conditions. Relict species are of particular importance, as they usually suffer more severely from human activities than do non-relict populations; the situation is also potentially critical, as many relict species and populations have the potential to colonize large areas when the climate changes. The more than 27 contributions in this book highlight the history and status of today’s relict species and populations and apply molecular genetics, morphometry, modelling and conservation biology to describe the past and present situations and to predict future trends of relict species’ distribution.

Abstract

This volume presents explicit approximations of the quasi-stationary distribution and of the expected time to extinction from the state one and from quasi-stationarity for the stochastic logistic SIS model. The approximations are derived separately in three different parameter regions, and then combined into a uniform approximation across all three regions. Subsequently, the results are used to derive thresholds as functions of the population size N.
