Plant functional identity contributes more to productivity and stability than functional diversity in wetlands

The functional trait diversity of plant communities regulates biodiversity effects on ecosystem function and stability. However, the role of functional trait diversity in driving ecosystem productivity and stability in natural wetlands remains unclear. Using vegetation data from 1139 sites across U.S. wetlands, we elucidate the role of functional diversity and functional identity of plant size traits and resource economics traits in driving satellite-derived productivity and temporal stability at continental scales.
