Abstract The European Union's Biodiversity Strategy 2030, reinforced by the new Nature
Restoration Law, targets restoring a minimum of 25,000 km of 'free-flowing rivers' by 2030 …

Fragmentation affects river ecosystems worldwide by dampening the movement and
dispersal of aquatic organisms and material (such as sediment, water, nutrients) across the …

Freshwater catchments can experience nutrient deficits that result in reduced primary and
secondary productivity. The most commonly limiting nutrients are nitrogen and phosphorus …

Measuring river response to dam removal affords a rare, important opportunity to study
fluvial response to sediment pulses on a large field scale. We present a before–after/control …

A river is an ecosystem where fish fauna represents an important structural element. To re-
establish connectivity, it is imperative to allow movement between functional habitats. Due to …

Fish passage research is important to mitigate the adverse effects of fragmented river
habitats caused by waterway structures. The scale at which this research is undertaken …

Sediment eroded from the headwaters of a large basin strongly influences channels and
ecosystems far downstream, but the connection is often difficult to trace. Disturbance …

Die Gesamtartenliste der sich im Süßwasser reproduzierenden Fische und Neunaugen
Deutschlands umfasst 111 etablierte Arten. Eine Rote-Liste-Kategorie wird für die 90 …

Ecological theory postulates that the size and isolation of habitat patches impact the
colonization/extinction dynamics that determine community species richness and population …

Barrier removal is increasingly being seen as the optimal solution to restore lotic habitat and
fish communities, however, evidence of its efficacy is often limited to single sites or …
