Sætersjøen i Nord-Odal: En undersøkelse av vannkvalitet med resipientvurdering i 2008
(NIVA-rapport;5691-2008, Research report, 2008)På grunnlag av undersøkelser i 2008 kan Sætersjøen karakteriseres som en grunn, markert humuspåvirket, kalkfattig og næringsfattig innsjø med lave konsentrasjoner av næringsstoffer og små algemengder. Vannkvaliteten kan ... -
Risiko for forurensing av råvannet til Oppegård vannverk ved akuttutslipp til Gjersjøen
(NIVA-rapport;5932, Research report, 2010)Rapporten beskriver mulige farer for forurensing av råvannet til Oppegård vannverk i Akershus ved akutt utslipp til Gjersjøen. Det er lagt vekt på å studere virkninger av utslipp som følge av uhell på vei i forbindelse ... -
In Inland China, Rice, Rather than Fish, Is the Major Pathway for Methylmercury Exposure
(Journal article; Peer reviewed, 2010)Background: Fish consumption is considered the primary pathway of methylmercury (MeHg) exposure for most people in the world. However, in the inland regions of China, most of the residents eat little fish, but they live ... -
Polychaetes from Jan Mayen (Annelida, Polychaeta)
(Journal article; Peer reviewed, 2010)A thorough literature review has been undertaken to establish the first complete account of polychaetes recorded from the area around the volcanic island of Jan Mayen. The annotated checklist lists 121 species-level taxa, ... -
Seasonal variation in marine C:N:P stoichiometry: can the composition of seston explain stable Redfield ratios?
(Journal article; Peer reviewed, 2011)Seston is suspended particulate organic matter, comprising a mixture of autotrophic, heterotrophic and detrital material. Despite variable proportions of these components, marine seston often exhibits relatively small ... -
Påvirkes laksesmolt av aluminium i brakkvann?Telemetriundersøkelser i Storelva i Holt, Aust-Agder,2007
(NIVA-rapport;6245, Research report, 2011)Storelva har vært fullkalket siden 1996. Kalkingen har ikke gitt den forventede økningen i fangst av laks. Vassdraget avviker således fra erfaringene man har fra andre kalka elver på Sørlandet. Flere hypoteser er ... -
Påvirkes laksesmolt av aluminium i brakkvann?Telemtriundersøkelser Storelva i Holt, Aust-Agder,2008
(NIVA-rapport;6246, Research report, 2011)Fangsten av laks i Storelva i Holt er lavere enn forventet. Flere hypoteser er forkastet. De senere årene har fokus vært på: vil aluminium i brakkvann kunne hemme smoltens utvandring fra elv til hav? I 2007 og 2008 ... -
Accumulation of polychlorinated biphenyls from contaminated sediment by Atlantic cod (Gadus morhua): Direct accumulation from resuspended sediment and dietary accumulation via the polychaete Nereis virens
(Journal article; Peer reviewed, 2012)Bioaccumulation of sediment‐associated polychlorinated biphenyls (PCBs) was examined in Atlantic cod (Gadus morhua) through direct diffusion from the sediment (via the water phase) and through the food chain (dietary ... -
Impact of an icy winter on the Pacific oyster (Crassostrea gigas Thunberg, 1793) populations in Scandinavia
(Journal article; Peer reviewed, 2012)The Pacific oyster (Crassostrea gigas) is an invasive species that has dispersed into Scandinavia during the last few decades. The objective of this study was to evaluate the effects of extreme winter conditions on the ... -

Gene Flow, Recombination, and Selection in Cyanobacteria: Population Structure of Geographically Related Planktothrix Freshwater Strains
(Journal article; Peer reviewed, 2013)Several Planktothrix strains, each producing a distinct oligopeptide profile, have been shown to coexist within Lake Steinsfjorden (Norway). Using nonribosomal peptide synthetase (NRPS) genes as markers, it has been shown ... -
Interactions between pH and nutrients on benthic algae in streams and consequences for ecological status assessment and species richness patterns
(Journal article; Peer reviewed, 2013)Eutrophication and acidification are among the major stressors on freshwater ecosystems in northern Europe and North America, but possible consequences of interactions between pH and nutrients on ecological status assessment ... -
