Although most studies of factors contributing to successful establishment and spread of non-
native species have focused on species traits and characteristics (both biotic and abiotic) …

Populations that experience severe stress may avoid extinction through adaptation by
natural selection. This process is called evolutionary rescue and has been studied under …

Stochastic factors affecting the demography of a single population are analyzed to
determine the relative risks of extinction from demographic stochasticity, environmental …

We reviewed empirical data and hypotheses derived from demographic, optimal foraging,
life-history, community, and biogeographic theory for predicting the sensitivity of species to …

This document introduces the viable salmonid population (VSP) concept, identifies VSP
attributes, and provides guidance for determining the conservation status of populations and …

Understanding population responses to novel environments is a central concern of both
evolutionary biology and ecology (Maynard Smith 1989; Bradshaw 1991; Hoffman and …

Because of the ubiquity of genetic variation for quantitative traits, virtually all populations
have some capacity to respond evolutionarily to selective challenges. However, natural …

Extinction risk in natural populations depends on stochastic factors that affect individuals,
and is estimated by incorporating such factors into stochastic models,,,,,,,,. Stochasticity can …

Stochasticity is a core component of ecology, as it underlies key processes that structure and
create variability in nature. Despite its fundamental importance in ecological systems, the …

Although it is widely acknowledged that the gradual accumulation of mildly deleterious
mutations is an important source of extinction for asexual populations, it is generally …
