WebCalculating community weighted means (CWM) is a useful way to calculate community trait values weighted by abundance of species in that community. Once CWMs are calculated for a datatset, you can run further analysis (ANOVAs, multivariate stats, etc.) to investigate trait patterns for entire communities rather than just individual species.
