The phylogenetic structure of ecological communities under change
Darwin first noticed that closely-related species tend to be more similar, and that this brings them into more severe competition with one another. In my thesis, I use information on the phylogenetic relatedness of species to help understand the processes that structure ecological assemblages. I sta...
