Short summary
The different contributions of gs, gm, and Vcmax to A indicated that plants utilized diverse trade-offs between CO2 supply and demand to maintain relatively high A. The iWUE was relatively low, but ranged widely, indicating that plants used a "profligate/opportunistic" water use strategy to maintain their survival, growth, and the structure of the community. These findings highlight the importance of covariation of gs, gm, and Vcmax for the adaptation of plants to the harsh karst environment.
