Freshwater biodiversity is under great threat across the globe as evidenced by more severe
declines relative to other types of ecosystems. Some of the main stressors responsible for …

Floodplains perform diverse functions, including attenuation of fluxes of water, solutes, and
particulate material. Critical details of floodplain storage including magnitude, duration, and …

The natural wood regime forms the third leg of a tripod of physical processes that supports
river science and management, along with the natural flow and sediment regimes. The wood …

Legacies are persistent changes in natural systems resulting from human activities.
Legacies that affect river ecosystems can result from human alterations outside of the river …

Atlantic salmon Salmo salar L. and brown trout Salmo trutta fario L. are species of high socio‐
economic and ecological value. Declining populations make them target species of fisheries …

Rivers are the great shapers of terrestrial landscapes. Very few points on Earth above sea
level do not lie within a drainage basin. Even points distant from the nearest channel are …

Inorganic sediment is not the only solid‐fraction component of river flows; flows may also
carry significant amounts of large organic material (ie large wood), but the characteristics of …

An investigation into the causes of species decline should include examination of habitats
important for multiple life stages. Integrating habitat impacts across life stages with life-cycle …

Trees fall naturally into rivers generating flow heterogeneity, inducing geomorphological
features, and creating habitats for biota. Wood is increasingly used in restoration projects …

Extensive habitat destruction and pollution have caused dramatic declines in aquatic
biodiversity at local to global scales. In rivers, the reintroduction of large woody debris is a …
