A study by CREAF and the Smithsonian Institute for Tropical Research shows that when the populations of large and mid-sized vertebrate animal are reduced, a phenomenon known as “defaunation,” this has negative repercussions for the rest of the ecosystem. This is a clear sign about the vulnerability of ecosystems to global biodiversity loss.
Scientists consider it key to understand why droughts kill so many trees and the influence of local forest histories on tree mortality. They also warn that we know very little about the joined effects of different disturbances on each ecosystem, and highlight the necessity to plan research projects covering more time and space.
