Acute effects of gas supersaturation on Atlantic salmon smolt in two Norwegian rivers
Stenberg, Sondre Kvalsvik; Velle, Gaute; Pulg, Ulrich; Skoglund, Helge (Journal article; Peer reviewed, 2020)Total dissolved gas (TDG) supersaturation downstream of hydropower plants may cause gas bubble disease (GBD) and harmful effects in fish. Little is known about tolerance levels of TDG supersaturation on Atlantic salmon ... -
Behavioural response of brown trout (Salmo trutta) to total dissolved gas supersaturation in a regulated river
Lennox, Robert J.; Thiemer, Kirstine; Vollset, Knut Wiik; Pulg, Ulrich; Stranzl, Sebastian; Nilsen, Cecilie Iden; Haugen, Thrond Oddvar; Velle, Gaute (Journal article; Peer reviewed, 2022)Total dissolved gas supersaturation from dams and power stations is a chronic freshwater pollutant that is toxic to animals with aquatic respiration. Laboratory ecotoxicology experiments have revealed capacity for captive ... -

The survey addresses themes such as learning in practice, transferable skills, motivation, laboratory and field learning, ... -
Biology students at work: using blogs to investigate personal epistemologies
Hole, Torstein Nielsen; Velle, Gaute; Riese, Hanne; Raaheim, Arild; Simonelli, Anne-Laure (Peer reviewed; Journal article, 2018-12-24)This paper reports an investigation of biology students’ discussion of knowing in work placements, as accounted in blogs. Twenty-two blogs, containing 78 individual entries, written in conjunction with a work placement ... -
Effects of nuisance submerged vegetation on the fauna in Norwegian rivers
Velle, Gaute; Skoglund, Helge; Barlaup, Bjørn Torgeir (Journal article; Peer reviewed, 2021)The abundance of aquatic vegetation is increasing in rivers and lakes worldwide. The aim of this study was to find how the macrophyte Juncus bulbosus Linnaeus affects salmonids and benthic macroinvertebrates in Norwegian ... -
Effects of within-lake variability of fossil assemblages on quantitative chironomid-inferred temperature reconstruction
Heiri, Oliver; Birks, Harry John Betteley; Brooks, Stephen J.; Velle, Gaute; Willassen, Endre (Peer reviewed; Journal article, 2003)We studied the effects of within-lake variation of subfossil chironomid assemblages on chironomid-inferred temperatures in five lakes in southern Norway. In each lake six replicate surface-sediment samples in the deepest ... -

To inform policy, ... -
Impacts of predation by Eurasian otters on Atlantic salmon in two Norwegian rivers
Sortland, Lene; Lennox, Robert; Velle, Gaute; Vollset, Knut; Kambestad, Marius (Journal article; Peer reviewed, 2023)1. The return of the Eurasian otter (Lutra lutra) to western Norway has sparked human–predator conflicts because otters prey on vulnerable Atlantic salmon (Salmo salar) populations. Although predation may not be the ultimate ... -
Late Quaternary chironomid community structure shaped by rate and magnitude of climate change
Mayfield, Roseanna J.; Langdon, Peter G.; Doncaster, C. Patrick; Dearing, John A.; Wang, Rong; Velle, Gaute; Davies, Kimberley L.; Brooks, Stephen J. (Journal article; Peer reviewed, 2021)Much is known about how climate change impacts ecosystem richness and turnover, but we have less understanding of its influence on ecosystem structures. Here, we use ecological metrics (beta diversity, compositional disorder ... -
Long-term responses of benthic invertebrates to rotenone treatment
Kjærstad, Gaute; Arnekleiv, Jo Vegar; Velle, Gaute; Finstad, Anders Gravbrøt (Journal article; Peer reviewed, 2021)Biological invasions are regarded as one of the largest threats to native biodiversity. The eradication of alien invasive fish or parasites by culling of hosts is a controversial conservation strategy, particularly when ... -
