Climatic drying is already being documented in many tropical regions, but its consequences for belowground dynamics in these carbon-rich ecosystems remain unclear. The Panama Rainforest Changes with Experimental Drying (PARCHED) experiment aims to address this by investigating seasonal and experimental drying effects on four forests in Panama varying in precipitation and soil fertility. The first four years of results include intriguing changes in soil respiration, nutrient availability, and microbial communities, with notable variation in drought response among forests. We encourage cross-site, collaborative work including long-term experiments, combined-disturbance studies, and empirical-theoretical-modeling collaborations to better predict tropical forest responses to drying.
