Dear folks,
I tried to calculate NRI/NTI for large community matrix (species
larger than 20,000, for instance) using Picante. My current PC memory
size (12 Gb) can not hold this kind of analyses. Does someone know how
to do with this issue? Thanks.

Dear all,
I am trying to compare environmental vs phylogenetic effects over one trait
that has evolved in a single branch. For that, I have 10 closely species
that have been collected over 7 localities. The number of localities in
which each species has been collected varies from 1 to 3. So some
Hi,
Scott's suggestion is a good one. Another option would be to split your
community matrix into pieces and analyze each separately. This may or may not
be feasible depending on the null model you are using.
I am in the process of rewriting most phylogenetic alpha/beta diversity methods
in
I've been trying to create a distance matrix from a dataset of
morphological characters, where the matrix contain some characters as
?. Is it possible to get a specifically euclidean matrix from that?
When I try to make the distance matrix, I get a what looks to me like
a distance matrix,, but it
