and contrast change within forested areas in conservation reserves, multiple-use public forests and private forests in the shorter term (decades).

Forest associated species at risk from isolation and the loss of genetic variation, and conservation efforts for those species

Submitted 06.05.08
Criterion: 
Keywords: 

Species with low genetic variation are widely held to be less able to withstand unexpected threats and so face a higher risk of extinction. In practice, it is diffi cult to demonstrate the level of genetic variation that has been lost in a species. However, it is possible to identify whether certain threatened species are becoming endangered ...
