Conservation's rare successes

摘要

Fifty-two species of vertebrates move a category closer to extinction every year, according to an analysis of more than 25,000 mammals, birds and amphibians published on 26 October (M. Hoffman et al. Science Am 10.1126/ science. 1194442; 2010), as the parties to the Convention on Biological Diversity meet in Nagoya, Japan. But falling biodiversity has been slowed by conservation efforts, such as those that repopulated parts of North America with the still-endangered black-footed ferret (Mustela nigripes, pictured).
