The role of dispersal in river network metacommunities: Patterns, processes, and pathways
A conceptual model is developed that predicts that the explanatory power of the river network peaks in mesic systems for obligate aquatic dispersers, and proposes directions of future avenues of research, including the use of manipulative field and laboratory experiments that test metacommunity theory in river networks.
Seasonality and predictability shape temporal species diversity.
This framework provides tools for examining trends at a variety of temporal scales, seasonal and beyond, and predicted that temporal beta diversity should be maximized in highly predictable and highly seasonal climates, and that low degrees of seasonality, predictability, or both would lower diversity in characteristic ways.
Dispersal distance and the pool of taxa, but not barriers, determine the colonisation of restored river reaches by benthic invertebrates
Overall, taxon pool occupancy rate was the most important driver of colonisation likelihood, followed by distance to nearest source, with the first kilometre particularly important.

Contrasting metacommunity structure and beta diversity in an aquatic‐floodplain system
Assessment of metacommunity structure and beta diversity patterns of instream benthic invertebrates, riparian carabid beetles and riparian spiders at fifteen sites in a river-floodplain system suggests varying levels of mass effects and species sorting shape river-Floodplain metacomunities, depending on habitat connectivity and dispersal ability.
Ecological values of Hamilton urban streams (North Island, New Zealand): constraints and opportunities for restoration
Investigating habitat quality, ecological function, and fish and macroinvertebrate community composition of gully streams in Hamilton City, New Zealand, and compared these with a selection of periurban sites surrounded by rural land suggests that riparian enhancement may have beneficial ecological outcomes in some urban streams.
Global patterns and drivers of ecosystem functioning in rivers and riparian zones
It is found that Earth’s biomes have distinct carbon processing signatures, and slow processing is evident across latitudes, whereas rapid rates are restricted to lower latitudes.
Prepare river ecosystems for an uncertain future
As the climate warms, we can’t restore waterways to pristine condition, but models can predict potential changes, argue Jonathan D. Tonkin, N. LeRoy Poff and colleagues. As the climate warms, we…
