DistLM-forward analysis; Akaike Information Criterion (AIC) = 229.85; R² = 0.5477; RSS = 37829; 3 variables. SS (trace) = portion of sum of squares related to the analysed predictor variable, %Var = percentage of variance in species data explained by respective variable in the row, %Cum = cumulative percentage of variance explained, df = degrees of freedom.
