Biological assessment of running waters in Denmark: introduction of the Danish Stream Fauna Index (DSFI)
Biological assessment of running waters is an old discipline (KOLKWITZ & MARsSON 1902), where different taxonomic groups i.e. diatoms, macrophytes, macroinvertebrates an d fish have been used forExpand

Long-term, habitat-specific response of a macroinvertebrate community to river restoration
1. In 1989 a 1.3 km channelized reach of the River Gelsa was restored to a new 1.9 km meandering course. The restored reach was subsequently (1989–95) monitored for changes in physical and biologicalExpand

Stream ecosystem properties and processes along a temperature gradient
We surveyed macrophyte community structure and measured community metabolism and nutrient uptake along a temperature gradient (9.7–17.4°C) in four Icelandic streams influenced by geothermal heating.Expand

Restoration of Skjern River and its valley—Short-term effects on river habitats, macrophytes and macroinvertebrates
Abstract The lower 19 km of the Skjern River was restored and transformed into a 26 km long meandering river. Three survey reaches and one control reach upstream of the restoration area were surveyedExpand

Variation in growth of the detritivore‐shredder Sericostoma personatum (Trichoptera)
1. We investigated the growth of the detritivore-shredder Sericostoma personatum by feeding groups of larvae on a fresh macrophyte, Potamogeton perfoliatus, conditioned sitka spruce needles, PiceaExpand

Impact of warming on CO2 emissions from streams countered by aquatic photosynthesis
Aquatic CO2 emissions are expected to increase if warming reduces photosynthesis relative to respiration. An analysis of streams across a 41 °C temperature gradient reveals that the thermal responsesExpand
