Genetic data are often used to assess 'population connectivity'because it is difficult to
measure dispersal directly at large spatial scales. Genetic connectivity, however, depends …

H abitat fragmentation-the reduction of continuous habitat into several smaller spatially
isolated remnants-is a significant threat to the maintenance of biodiversity in many terrestrial …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Extinction is rarely random across ecological and geological time scales. Traits that make
some species more extinction-prone include individual traits, such as body size, and …

Genetic studies have typically inferred the effects of human impact by documenting patterns
of genetic differentiation and levels of genetic diversity among potentially isolated …

Theoretical models pertaining to feedbacks between ecological and evolutionary processes
are prevalent in multiple biological fields. An integrative overview is currently lacking, due to …

From the snub-nosed monkeys of China to the mountain gorillas of central Africa, our closest
nonhuman relatives are in critical danger worldwide. A recent report, for example, warns that …

Genetic variability is the clay of evolution, providing the base material on which adaptation
and speciation depend. It is often assumed that most interspecific differences in variability …

The traditional view that species are held together through gene flow has been challenged
by observations that migration is too restricted among populations of many species to …

Kerr and Dickie propose the development of a new ecological theory, one that can lead to a
more effective remedy for the drastic effects of heavy fishing on natural communities of …
