Diverging life cycle patterns of two Diamesa species (Diptera, Chironomidae) in High Arctic streams, Svalbard
Schütz, Stefan Andreas; Brittain, John E.; Füreder, Leopold (Journal article, 2021)The fauna of streams in the High Arctic, dominated by chironomids, is shaped by extreme environmental conditions that represent the physiological limits for benthic invertebrates. Despite their ecological importance, little ... -
Ecological condition, biodiversity and major environmental challenges in a tropical river network in the Bago District in South-central Myanmar: First insights to the unknown
Eriksen, Tor Erik; Friberg, Nikolai; Brittain, John E.; Søli, Geir; Ballot, Andreas; Årstein-Eriksen, Eirin; Blakseth, Tomas Adler; Braaten, Hans Fredrik Veiteberg (Journal article, 2021)Freshwater ecosystems in the Indo-Burma biodiversity hotspot face immediate threats through habitat loss and species extinction. Systems to monitor ecological status and trends in biodiversity are therefore crucially needed. ... -
Ecological correlates of riverine diatom and macroinvertebrate alpha and beta diversity across Arctic Fennoscandia
Brittain, John E.; Heino, Jani; Friberg, Nikolai; Aroviita, Jukka; Kahlert, Maria; Karjalainen, Satu‐Maaria; Keck, François; Lento, Jennifer; Liljaniemi, Petri; Mykrä, Heikki; Schneider, Susanne C.; Ylikörkkö, Jukka (Journal article, 2020-09)Arctic freshwaters support biota adapted to the harsh conditions at these latitudes, but the climate is changing rapidly and so are the underlying environmental filters. Currently, we have limited understanding of broad‐scale ... -
Effects of pollution-induced changes in oxygen conditions scaling up from individuals to ecosystems in a tropical river network
Eriksen, Tor Erik; Jacobsen, Dean; Demars, Benoit; Brittain, John E.; Søli, Geir; Friberg, Nikolai (Journal article, 2021)Anthropogenic inputs of nutrients and organic matter are common in tropical lowland rivers while little is known about the pollution-induced changes in oxygen availability and respiratory performance of ectotherms in these ... -
Etterundersøkelser ved små kraftverk
Frilund, Gunn E.; Simensen, Trond; Bremnes, Trond; Saltveit, Svein J.; Brittain, John E.; Ihlen, Per G. (Report, 2010)Uheldige sumvirkninger for landskapet er stort sett unngått i studieområdet, siden nøkkelelementer som fosser er skjermet. De enkelte anleggene gir også begrensede konsekvenser, men rørgatetraséer og veianlegg kan være ... -
A global perspective on the application of riverine macroinvertebrates as biological indicators in Africa, South-Central America, Mexico and Southern Asia
Eriksen, Tor E.; Brittain, John E.; Søli, Geir; Jacobsen, Dean; Goethals, Peter; Friberg, Nikolai (Journal article, 2021)The aim of this study is to generate a first global overview of pressures and methods used to assess the environmental quality of rivers and streams using macroinvertebrates. In total, 314 peer-review studies were reviewed, ... -
Hydropower-driven thermal changes, biological responses and mitigating measures in northern river systems
Heggenes, Jan; Stickler, Morten; Alfredsen, Knut; Brittain, John E.; Adeva-Bustos, Ana; Huusko, Ari (Journal article, 2019)Water temperatures control life histories and diversity of aquatic species. Hydropower regulation, particularly in high head systems, alters natural water temperature regimes, which may have profound and long-term impacts ... -
The macroinvertebrate communities of two contrasting Norwegian glacial rivers in relation to environmental variables
Brittain, John E.; Saltveit, Svein J.; Castella, Emmanuel; Bogen, Jim; Bønsnes, Truls E.; Blakar, Inggard; Bremnes, Trond; Haug, Ingrid; Velle, Gaute (Journal article, 2001)1. Macroinvertebrate communities in two Norwegian glacial rivers, one in the western fjords (Dalelva) and one in the eastern mountains (Leirungsåi), were investigated during three time periods in 1996 and 1997. 2. Channel ... -
Norsk vassdragsforvaltning ved et veiskille?
L’Abée-Lund, Jan Henning; Brittain, John E. (Journal article, 2002)Forvaltning av vannressurser har internasjonalt og nasjonalt endret karakter de senere år. Et fellestrekk er at det ikke nødvendigvis er nok vann til alle brukerinteresser, samtidig som vassdragsmiljøet har fått økt ... -
Spatial and temporal variation in Arctic freshwater chemistry—Reflecting climate‐induced landscape alterations and a changing template for biodiversity
Huser, Brian J.; Futter, Martyn N.; Bogan, Daniel; Brittain, John E.; Culp, Joseph M.; Goedkoop, Willem; Gribovskaya, Iliada; Karlsson, Jan; Lau, Danny C. P.; Rühland, Kathleen M.; Schartau, Ann Kristin; Shaftel, Rebecca; Smol, John P.; Vrede, Tobias; Lento, Jennifer (Journal article, 2020-11)Freshwater chemistry across the circumpolar region was characterised using a pan‐Arctic data set from 1,032 lake and 482 river stations. Temporal trends were estimated for Early (1970–1985), Middle (1986–2000), and Late ... -
Weirs as a Mitigation Measure in Regulated Rivers - The Norwegian Experience
