Dear Wout,

I was just strugling with a bifactorial adonis myself too :) I have the
original Marti Anderson article (I asked the author, and I can send it to
you), which is really nice and clear. She uses Bray-curtis in the three
examples.

Anderson, M. J. 2001. A new method for non-parametric multivariate analysis
of variance. Austral Ecol 26:32-46.

In the primer course, they recommend Bray-Curtis for ecological/community
data (if I remember). You can find the literature in Clarck articles (which
I can send also). For well behaved data (as abiotic variables) they use to
recommend Euclidean dist.

How are you implementing your design in ADONIS?
I actually also had a doubt about the ADONIS. How do we estimate the %
explained by each factor separatly?

Hope this helps,

Cheers,
Marta
