Characterizing direction and magnitude of community change in response to a continuous predictor?

Pedro Lima Pequeno 
Hi Brian,

a simple approach would be to summarize species composition using some
ordination method (e.g. PCoA) and then use it as a response variable
in a linear model where the predictors would be the environmental
gradient and region. Therefore, you could explicitly test for an
interaction between gradient and region, i.e. whether the response of
species composition to the gradient changes across regions. The
resulting slopes could be a measure of direction and magnitude of
change.

Cheers,

Pedro
