Dear list,
We are working with a dataset of bird community composition across four
regions, each of which contain three land use treatments. We are
interesting in understanding if the community dissimilarity within regions
and between regions differs according to land use treatment. I
Dear Andy,
For testing the null hypothesis of no land use effect, what you suggest does
not take into account the nested structure of your design (with land use
nested in location).
In ?adonis:
If the experimental design has nestedness, then use strata to test
hypotheses. For instance, imagine
Dear Etienne,
Thanks for your response, and yes I see clearly now the nested structure.
However, I think this is not getting at our question. I believe this method
would address the question of how different are communities given different
land use treatments (and given that fact that treatments
