Forty years of tree data show global change altering Amazon and Andean forest diversity

Global change is causing significant shifts in tree diversity across Amazon and Andean forests, with some areas declining and others increasing. Forty years of tree-tracking data reveal that hotter, drier regions are losing species, while some intact, dynamic forests are gaining them, influenced by temperature and rainfall patterns. The Northern Andes may serve as a refuge for species displaced by climate change, highlighting the need for targeted conservation efforts in these vital tropical ecosystems.
