Climate change drives widespread amphibian extinctions

...ctious diseases are a real and immediate threat to biodiversity and a growing challenge for humankind. The decline of amphibians in apparently pristine, protected habitats in Costa Rica and elsewhere has perplexed conservation biologists since 1990, when the problem was first recognized. At least 110 species of ...

Insect predation sheds light on food web recovery after the dinosaur extinction

The recovery of biodiversity after the end-Cretaceous mass extinction was much more chaotic than previously thought, according to paleontologists. New fossil evidence shows that at certain times and places, plant and insect diversity were severely out of balance, not linked as t...
