Describing, explaining and predicting community assembly: a convincing trait-based case study

摘要

Direct gradient analysis describes community change along abiotic gradients. Baastrup-Spohr etal., in this issue of the Journal of Vegetation Science, go beyond description when exploring community assembly by trait selection. Using a system with a single overriding hydrological gradient, combined with functional traits related to these selective pressures, they also explain and predict community assembly through trait-based filtering.
