Study confirms amphibians' ability to predict changes in biodiversity
Date:10/28/2008

traveling through a tropical or temperature region also influences how quickly the types of animals change. Given a mountain of a certain size, the researchers found, the amphibian and bird communities change more quickly if one is climbing a mountain in the tropics than in a temperate region.

"There are more species in the tropics and the species are generally more specially adapted to particular environmental conditions," said Jetz. "This suggests that tropical species may be more severely impacted by a given temperature increase as a result of climate change."

For the study, he and Buckley produced a series of global maps of environmental turnover and the associated changes in amphibian and bird communities that reveal that the identities of birds and amphibians change particularly quickly in mountainous regions such as the Andes and Himalayas.

"Understanding how environmental changes over space influence biodiversity patterns provides important background for forecasting how biodiversity will respond to environmental changes over time such as ongoing temperature increases," said Buckley.
