Description Our aim was to test how dispersal ability affects metacommunity structure and associated species distributions by sampling different species groups in the same plots. Our findings provide strong support for the hypothesis that both environmental and spatial variables structure metacommunities of organisms with very different dispersal abilities, including microscopic diatoms. In addition, we show for the first time that the strengths of these effects and their scale dependence may be predicted using important trait differences between organisms, for example differences in propagule size.
