Amazon-Andes Forest Diversity Shifts
Coverage from SciTechDaily, ScienceDaily, and others
Four decades of monitoring across 406 forest plots show that climate change is reshaping tree diversity unevenly across the Amazon and Andes.
Hotter, drier, and more seasonal forests—including parts of the Central Andes, Guyana Shield, and central-eastern Amazon—are more likely to lose species, while the Northern Andes and western Amazon show gains or potential refuge value. The findings point to the importance of protecting intact forests and maintaining connected elevational corridors so species can move as conditions change.
The story is slightly reframed with sharper detail on where losses and refuges are concentrated, and it now adds corridor-mapping evidence showing that connected elevational routes are being constrained by human pressure. The underlying conclusion remains the same: climate change is unevenly reducing tree diversity while intact, connected forests matter for species movement.
The story is broadly the same, but the framing has been tightened around connectivity and regional conservation planning. The newer version more explicitly links species gains and losses to elevational corridors and landscape fragmentation, while adding the long-term monitoring frame and 10-country scope.
