Abstract Ongoing environmental change is forecast to lead lower precipitation and concomitant species losses in tropical regions. These may affect generalist that provide essential ecosystem services, such as controlling the rate at which nutrients become available for uptake by other organisms forests. Here, we use a long‐term (16 years) rainwater exclusion experiment primary Amazonian rainforest (Caxiaunã National Forest, Northern Brazil) test whether induced water stress (“drought”) affects richness of ants, their abundance (i.e., nest density), distance they detect food resources baits). The number ant colonies was reduced 50% drought‐induced plot, composition differed between control (typical moist forest) plots. Although ants nested both drought plots had shorter estimated foraging distances than habitat specialists, these detected baits not affected drought. We conclude extremely high diversity forest be able buffer detrimental effects on resource detection rates ants. Different were also functionally similar wet‐forest cannot forage under drier conditions.
