Dear all,

I'm interested in analyze alpha and beta diversity components in an
hierarchical way using adipart function. However, my design isn't nested. I
collected spiders on five plant species (5 different "architecture"),
plants on different patches , patches on 12 different sites. I sampled 100
individual plants within each locality, 20 individuals from each of the
five plant species. In addition, I sampled 20 patches within each locality.
So, my table is similar with this one:

   plant architecture patch site  1 1 1 1  2 1 1 1  3 1 1 1  4 1 2 1  5 2 2
1  6 2 3 1  7 2 3 1  8 2 4 1  9 3 4 1  10 3 5 1  11 3 6 1  12 3 6 1  ... ...
... 2  ... ... ... 2  ... ... ... 2

I've run the adipart function and the following warning message appear:


Warning message:
In adipart.formula(species ~ ., hierar, index = "richness", nsimul = 1000) :
  levels are not perfectly nested

Is there any problem with Additive Diversity Partitioning method when the
design isn't nested?

Thank you all in advance,
Thiago.
