Article Synopsis
- * An analysis of tree-ring data from 3,343 populations and 438 species shows tropical trees grow about twice as fast but live shorter lives than trees in temperate and boreal regions.
- * The study finds that as temperatures rise and aridity increases in tropical lowlands, tree longevity decreases, suggesting higher tree mortality and changes in forest composition in regions like the Amazon and western Africa due to climate conditions.
Widely distributed tree species usually face different growth conditions across gradients of climate variables. Hymenaea courbaril inhabits most of Neotropical lowlands, where its growth is limited by low precipitation under seasonal precipitation regimes. However, it is still unclear what are the drivers of growth variability at its distribution limits, where populations are most vulnerable to climate change.
