Table 4.
Deviance explained by variables themselves for generalized dissimilarity between Bray–Curtis distance and geographical, genetic and environmental distances. Values given as NA for variable importance result from such variables being dropped because they explained negligible deviance of in the model. Predictor importance is assessed as the percentage change in deviance explained in models with and without the variable randomized.
