Schematic description of the theoretical expectations for phylogenetic community assembly within and between communities, based on stochastic (dispersal-driven) and deterministic (environment-driven) processes. (a) Taxa associations are analysed using their phylogenetic structure (mean-pairwise-distance (MPD), mean-nearest-taxon-distance (MNTD) or phylogenetic distance (UniFrac)) for each date of each time-series and by comparing it to expected patterns from null-model simulations of random assembly (grey box): clustering and overdispersion (above and below the random expectation, respectively) signal communities that are composed of species phylogenetically closer or further apart than expected by chance, respectively, as a sign of deterministic processes. (b) Predicted patterns in phylogenetic community similarity depending on limitation (black line) and no limitation (grey line) in taxa dispersal among sites. (c) Predicted change in phylogenetic similarity for completely stochastic (grey) and deterministic (black) models of community assembly along an environmental gradient (e.g. lake physics and chemistry).
