August 10, 2015 - Tropical forests in the Andes Mountains are changing in the face of climate change. A new study published in PNAS reveals the number of highland tree species is decreasing as a result of lowland tree species moving upslope along South America’s longest mountain chain in response to rising temperatures and changing rainfall patterns. Instead of shifting to different locations, the highland trees are retracting, or dying back. The results suggest tropical tree species in the Andes are at risk of extinction with ongoing warming. "The effects of climate change are everywhere – you can’t escape it," said Kenneth J. Feeley, a researcher in FIU’s Department of Biological Sciences and International Center for Tropical Botany (ICTB). "Some people hold the notion that the Amazon is an isolated and pristine ecosystem, immune to disturbances. We need to change our mindset and open our eyes to the fact that even in the middle of the Amazon or the remote Andes Mountains, species are at risk. Tropical forests, and the thousands of rare or endemic species they support, are highly sensitive to changes in climate and that they are perhaps some of the most threatened ecosystems of all. Climate change is pervasive and dangerous."
