The manner in which patches are delineated in spatially realistic metapopulation models will influence the size, connectivity, and extinction and recolonization dynamics of those patches. Most ...

AbstractThe adverse influence of habitat degradation on the survival of populations may sometimes be amplified by rapid evolution over ecological timescales. This phenomenon of “evolutionary suicide” ...

Sutirth Dey and Amitabh Joshi of Jawaharlal Nehru Centre for Advanced Scientific Research, Bangalore, India used laboratory metapopulations of fruitflies in the first experimental test of whether a ...

Heterogeneity is ubiquitous in real-world host populations, yet most theories assume homogeneity. Using a metapopulation model, we examine how host heterogeneities, such as uneven movement patterns ...

The need to protect crop genetic resources has sparked a growing interest in the genetic diversity maintained in traditional farming systems worldwide. Although traditional seed management has been ...

Cheetahs have vanished from 90% of their historical range in Africa. A metapopulation project in South Africa has almost doubled the population of cheetahs in this project in less than nine years. The ...

Forbes contributors publish independent expert analyses and insights. GrrlScientist writes about evolution, ecology, behavior and health. Genetic analysis of more than 90 butterfly museum specimens ...

JACKSON – In 1993, Chris Servheen affixed his signature to a plan for the recovery of grizzly bears – a plan that called for rebuilding the bears’ numbers in six geographically distinct populations.

There’s a bright side to everything, perhaps even mass die-offs of animals. If one population of a species goes rapidly and completely extinct – maybe thanks to a forest fire or hurricane – it may ...
