Sampling intensity influences the estimation of functional diversity indices of fish communities

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 div...
