Ecological strategies reflect the mechanisms used for species to sustain a population. Predicting plant growth in ecological communities is crucial, especially with climate change impacting ecosystem functioning. By employing large dataset subtropical Brazilian Atlantic Forest (BAF), we evaluated whether species' relative rates (RGR) are explained by their strategies. Principal component analyses summarised relationships among functional traits (leaf, wood and stature traits) inform about of 121 tree species. We tested three principal components as predictors RGR all collectively, canopy understory separately. Species exhibiting larger small structured leaves have faster growth. Tall trees, softer grew faster, whereas taller stature, denser wood, more nutrient‐rich had higher RGR. Therefore, that combine smaller leaf area key determinants grow from BAF, conferring greater advantage converting local resources into stem These findings highlight importance understanding coordination between trait‐based growth, which essential functioning changing environments.

ABSTRACT Forest composition is changing, yet the consequences for terrestrial carbon cycling are unclear. In eastern United States, water‐demanding “mesophytic” tree species replacing “xerophytic” oaks ( Quercus spp.) and hickories Carya spp.), raising concerns that forest productivity will become increasingly sensitive to more frequent severe drought conditions predicted region. However, we have a limited understanding of extent which mortality risk xerophytes versus mesophytes coordinated with their growth sensitivity during drought. Here, evaluated dynamics 20 abundant States following in summer 2012. We synthesized data from ~4500 inventory plots used an approach quantified relative responses between co‐located trees minimize impacts environmental heterogeneity. found were just as likely perish co‐occurring but terms diminished growth. These findings suggest xerophytic decline lead reduced uptake management efforts conserve oak‐hickory stands be decisive sustain mitigation potential these forests. also growth‐mortality relationships differed functional groups. Among xerophytes, survival decoupled. mesophytes, there was high degree coordination, where experienced greater reductions. Therefore, water deficits most vulnerable drought‐driven die‐off events moving forward.
