Microbiome network theory predicts that highly connected hubs act as keystones, but this has never been empirically tested in nature.

ABSTRACT As beavers ( Castor spp.) are reintroduced to streams in the northern hemisphere and nature‐based process‐based river restoration emphasizes human‐built analogues for beaver dams, it is reasonable ask how dams ponds compare different types of small constructed by humans diverse purposes. We use published research as a basis comparing effects four human dams—beaver dam analogues, earthen embankments perpendicular flow that used create stock ponds, check mill dams. these with respect water balance three‐dimensional hydrologic connectivity, sediment, particulate organic matter carbon, nutrients, habitat, biota. These assessments inform us ranking from generally most beneficial providing ecosystem services (beaver meadows multiple dams) least (mill dams), recognizing may not be at some sites infrastructure property within corridor, where they impede upstream migration invasive species or provide lentic habitat corridor. This comparison among highlights need on cumulative along corridor across catchment, well identifying gaps our understanding specific including carbon nutrient dynamics.
