Short summary

The different contributions of g_s, g_m, and V_cmax 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 g_s, g_m, and V_cmax for the adaptation of plants to the harsh karst environment.
