Dear Zhifeng,
You have already sent me three personal emails about this, and I've already
responded that you should try with calc.FRic = FALSE. What is likely
happening is that R struggles to compute the multidimensional convex hull
volume with your data -- this is explained in ?dbFD. Why don't
Dear Kay,
I ran your code and found no significant interactions. You just got
unlucky with rnorm(), as can happen. Try it again.
Cheers,
Etienne

Dear Ivan,
In such situations, it's probably best to contact the corresponding author
first.

Dear Mario,
For the Gower dissimilarity you may want to check
Library(FD)
?gowdis
which allows weights to be assigned to traits/variables (sometimes useful),
and implements Podani's 1999 approach for ordinal traits/variables.

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 Erika,
You may want to consider this approach:

context. Ecology 90:363-368.
