Angie,
You could apply customized contrasts. Check this:

I'd also appreciate comments on the approach that I used in the
above-mentioned link!
Cheers,
Kay

Dear Kay,
I ran your code and found no significant interactions. You just got
unlucky with rnorm(), as can happen. Try it again.
Cheers,

hello all,
in https://stat.ethz.ch/pipermail/r-sig-ecology/2010-April/001221.html
jari oksanen describes how to use custom contrasts with adonis.
i'm curious whether there's also a way to yield the according
significance tests - else i don't see much purpose in customizing your
gavin,
sorry - of course it should be permute.strata=F, permuting within
individual sites!
but despite of this the code should work, doesn't it?
thanks,
kay

hi eduard,
i faced similar problems recently and came to the below solution.
i only try to address the pseudoreplication with an appropiate
permutation scheme.
when it comes to testing the interactions, things may get more complicated.
the code is in no way approven of, but at least it maybe
hello all,
i want to know whether pooled invaded quadrats (n=6) show decreased
diversity compared to pooled uninvaded quadrats (n=6) - or in other
words, whether species are lacking from invaded quadrats.
to yield confidence limits i bootstrapped pooled absence/presence
species data from
