I performed CCA with the presence/absence (0/1) species data to detect main explanatory factors of the species composition. However, to analyze further the change in species composition along a particular axis, I want to do some analyses (for e.g. want to see how the environmental parameters are interacting to explain the temporal variation along that particular axis) using the species and site scores of that axis. However, I am ‘not quite sure’ if I can use these weighted average (WA) scores as surrogates of compositional change (frequencies / abundances).
Any suggestion would be of great help!
Thanking you
