Evaluating the role of plant functional trait variation in tropical forests we found that environmental controls and different trait components, such as phenotypic plasticity, genetic adaptation and random factors differed between neotropical tree species and plant tissues. Results suggest that leaf traits varied in association with light regime and soil nutrient content, whereas wood traits were related to topography and soil water content. We furthermore found that phenotypic plasticity increased with the range size of congeneric tree species, indicating less plasticity within range restricted endemics compared to their widespread congeners. Our findings indicate that differences in phenotypic trait plasticity affect stress tolerance and range size of tropical tree species, and therefore suggest that endemic species could be especially prone to projected climate change.
