Hello,
I was wondering whether somebody could point me in the right direction with
this problem. I would like to statistically compare the functional
diversity of two communities while at the same time account for the fact
that within each community species are not independent data points. A
univariate equivalent would be for example computing variance in body
mass in each of two assemblages and testing which one is higher but, again,
accounting for phylogenetic relatedness. ("A phylogenetically-controlled
Levene test?")
So far I have been unable to locate information on this. Being very much a
non-expert it occurs to me that one could try weighing each species by its
evolutionary distinctiveness within the community or something along these
lines before computing functional diversity. However I have not found any
references to such an approach.
I would be very grateful for any leads or, instead, indications that it is
not necessary to control for phylogenetic relatedness in this kind of
analyses.
Thanks in advance
Kaspar
