Species intraspecific variation drives tropical forest drought resistance

Nature · first seen 12.08.2026

A new study finds that substantial intraspecific variation and species turnover drive coordinated shifts in drought resistance across drier tropical forests, demonstrating that distinct populations of the same tropical tree species vary significantly in their ability to withstand drought.
