摘要: Functional diversity has emerged as a key component of biodiversity in recent two decades, which has been extensively used to assess the health of aquatic ecosystems and predict the responses of fish communities to disturbances. However, sampling intensity may affect the estimation of functional diversity indices and thus lower the validity of functional diversity indices in monitoring long-term changes in ecosystem status. In this study, we used a simulation study to investigate the effect of sampling intensity on the estimation of functional …
