Multiyear Drought Strengthens Positive and Negative Functional Diversity Effects on Tree Growth Response Open
Mixed‐species forests are proposed to enhance tree resistance and resilience to drought. However, growing evidence shows that tree species richness does not consistently improve tree growth responses to drought. The underlying mechanisms r…

Dynamics and environmental drivers of methane and nitrous oxide fluxes at the soil and ecosystem levels in a wet tropical forest Open
Tropical forests are critical for maintaining the global carbon balance and mitigating climate change, yet their exchange of greenhouse gases with the atmosphere remains understudied, particularly for methane (CH4) and nitrous oxide (N2O).…

Large range sizes link fast life histories with high species richness across wet tropical tree floras Open
Understanding how the traits of lineages are related to diversification is key for elucidating the origin of variation in species richness. Here, we test whether traits are related to species richness among lineages of trees from all major…

Thermal acclimation dampens the warming-induced increase in ecosystem respiration Open
Global warming increases ecosystem respiration (ER), creating a positive carbon-climate feedback. Thermal acclimation, the direct responses of biological communities to reduce the effects of temperature changes on respiration rates, is a c…

Multi-year drought strengthens positive and negative functional diversity effects on tree growth response Open
Mixed-species forests are proposed as strategy to increase the resistance and resilience of forests to drought stress. However, evidence suggest that increasing tree species richness does not consistently enhance tree growth responses to d…

Tree drought–mortality risk depends more on intrinsic species resistance than on stand species diversity Open
Increasing tree diversity is considered a key management option to adapt forests to climate change. However, the effect of species diversity on a forest's ability to cope with extreme drought remains elusive. In this study, we assessed dro…

Inferred drought‐induced plant allocation shifts and their impact on drought legacy at a tropical forest site Open
While droughts predominantly induce immediate reductions in plant carbon uptake, they can also exert long‐lasting effects on carbon fluxes through associated changes in leaf area, soil carbon, etc. Among other mechanisms, shifts in carbon …
