Diverse phylogenetic neighborhoods enhance community resistance to drought in experimental assemblages

Abstract Although the role played by phylogeny in the assembly of plant communities remains as a priority to complete the theory of species coexistence, experimental evidence is lacking. It is still unclear to what extent phylogenetic diversity is a driver or a consequence of species assembly proces...
