Loss of forest intactness increases extinction risk in birds

Fragmentation within intact forests has a higher impact on vertebrate biodiversity than equivalent losses in already degraded landscapes, but the relationship between forest 'intactness' and extinction risk has not been quantified.

Scientists predict extinction risk for hard-to-track species

Species are going extinct all over the world: Scientists believe that Earth is losing between 200 and 2,000 species every year. That number is squishy, partly because there are so many species for which they lack good data—particularly ...

The environment determines Caribbean hummingbirds' vulnerability

Hummingbird specialization and vulnerability are often predicted based on physical traits. Scientists have now found that this is not the case for hummingbirds on the Caribbean islands. Instead, the bird's environment is ...
