TL;DR: It is concluded that regression of similarity against distance unites several ecological phenomena such as dispersal propensity and environmental structuring, and provides an effective approach for gauging the spatial turnover across sites.

TL;DR: A better understanding of the relative roles of species sorting, mass effects and dispersal limitation in affecting aquatic metacommunities requires the following: characterising dispersal rates more directly or adopting better proxies than have been used previously; considering the nature of aquatic networks; and combining correlative and experimental approaches.

TL;DR: The results clearly indicate a dominant role of deterministic processes on bacterial assemblages and highlight that bacteria show strong habitat associations that have likely emerged through evolutionary adaptation.

TL;DR: The results suggest that patterns between macro- and microorganisms are not fundamentally different, but the level of environmental control varies according to dispersal ability.

TL;DR: Examination of species traits, spatial extent, latitude and ecosystem type on the nestedness and turnover components of beta diversity provides evidence that species turnover, being consistently the larger component of total beta diversity, and nestedness are related to the latitude of the study area and intrinsic organismal features.
