Biotic and human vulnerability to projected changes in ocean biogeochemistry over the 21st century
(Journal article; Peer reviewed, 2013)Ongoing greenhouse gas emissions can modify climate processes and induce shifts in ocean temperature, pH, oxygen concentration, and productivity, which in turn could alter biological and social systems. Here, we provide a ... -
From Green to Red: Horizontal Gene Transfer of the Phycoerythrin Gene Cluster between Planktothrix Strains
(Journal article; Peer reviewed, 2013)Horizontal gene transfer is common in cyanobacteria, and transfer of large gene clusters may lead to acquisition of new functions and conceivably niche adaption. In the present study, we demonstrate that horizontal gene ... -
Transgenic (cyp19a1b-GFP) zebrafish embryos as a tool for assessing combined effects of oestrogenic chemicals
(Journal article; Peer reviewed, 2013)Endocrine disrupting chemicals and especially oestrogen receptor (ER) agonists have been extensively studied over the years due to their potential effects on sexual development and reproduction in vertebrates, notably fish. ... -
Top-down versus bottom-up project appraisal processes, and external review. Evidence from Norway and China
(Peer reviewed; Journal article, 2013)Project appraisal plays an important role in choosing the right project and is crucial for the success of public investment projects. Different factors may affect the choice of appraisal process in different countries. By ... -
EDA-EMERGE: an FP7 initial training network to equip the next generation of young scientists with the skills to address the complexity of environmental contamination with emerging pollutants
(Journal article; Peer reviewed, 2013)The initial training network consortium novel tools in effect-directed analysis to support the identification and monitoring of emerging toxicants on a European scale (EDA-EMERGE) was formed in response to the seventh EU ... -
Biofilmdannelse i VAVs ledningsnett med nye Oset vannbehandlingsanlegg
(Journal article; Peer reviewed, 2013)Det ble i 2012 gjennomført kvalitative og kvantitative målinger av biofilmdannelse i råvann, filtrert vann, rentvann og nettvann i Osets forsyningsområde i Oslo. Målet med biofilmmålingene var å undersøke/dokumentere ... -
Pelagic community production and carbon-nutrient stoichiometry under variable ocean acidification in an Arctic fjord
(Journal article; Peer reviewed, 2013)Net community production (NCP) and carbon to nutrient uptake ratios were studied during a large-scale mesocosm experiment on ocean acidification in Kongsfjorden, western Svalbard, during June–July 2010. Nutrient depleted ... -
Ecological status assessment of European lakes: a comparison of metrics for phytoplankton, macrophytes, benthic invertebrates and fish
(Journal article; Peer reviewed, 2013)Data on phytoplankton, macrophytes, benthic invertebrates and fish from more than 2000 lakes in 22 European countries were used to develop and test metrics for assessing the ecological status of European lakes as required ... -
Lack of sea urchin settlement may explain kelp forest recovery in overgrazed areas in Norway
(Journal article; Peer reviewed, 2013)In this study, we investigated whether failure of sea urchin recruitment can explain an ongoing phase shift from overgrazed, barren grounds to kelp forests along the coast of mid- Norway. Settlement of sea urchins on ... -
“Candidatus Similichlamydia laticola”, a novel Chlamydia-like agent of epitheliocystis in sevenconsecutive cohorts of farmed Australian Barramundi, lates calcarifer (Bloch)
(Journal article; Peer reviewed, 2013)Six consecutively hatched cohorts and one cohort of pre-hatch eggs of farmed barramundi (Lates calcarifer) from south Australia were examined for Chlamydia-like organisms associated with epitheliocystis. To identify and ... -
A water level drawdown index for aquatic macrophytes in Nordic lakes
(Journal article; Peer reviewed, 2013)Many northern lakes are regulated to enhance hydropower production and flood protection. This bears hydromorphological pressures which are important factors causing lowered ecological status. Water level fluctuation triggers ... -
The distribution of the Mussel Mytilus species along the Norwegian coast
(Journal article; Peer reviewed, 2013)Mussels (Mytilus spp.) are used frequently in biological effects studies and biomonitoring programs either as transplanted groups or native populations. However, as a result of the similarities in the external morphology ... -
Implications of elevated CO2 on pelagic carbon fluxes in an Arctic mesocosm study - an elemental mass balance approach
(Journal article; Peer reviewed, 2013)Recent studies on the impacts of ocean acidification on pelagic communities have identified changes in carbon to nutrient dynamics with related shifts in elemental stoichiometry. In principle, mesocosm experiments provide ... -
Pesticide risk assessment and management in a globally changing world—report from a European interdisciplinary workshop

Nuisance growth of Juncus bulbosus: the roles of genetics and environmental drivers tested in a large-scale survey
(Journal article; Peer reviewed, 2013)1. Invasive species can transform aquatic ecosystems, and the nuisance growth of the freshwater macrophyte Juncus bulbosus has become a problem in many lakes and rivers in northern Europe. It affects biodiversity strongly ... -
Sjøørret i Trondheimsfjorden; en utdøende ressurs. Hva betyr bekker for sjøørreten?
(Journal article; Peer reviewed, 2013)Sjøørretbestanden i Trondheimsfjorden har trolig aldri vært lavere, og årsaken knyttes først og fremst opp mot faktorer i saltvann. Samtidig synliggjøres betydelige tap av areal, arealkvalitet og vannkvalitet i sjøørretbekkene ... -
Influence of flood risk characteristics on flood insurance demand: a comparison between Germany and the Netherlands
(Journal article; Peer reviewed, 2013)The existence of sufficient demand for insurance coverage against infrequent losses is important for the adequate function of insurance markets for natural disaster risks. This study investigates how characteristics of ... -
What is the impact of kelp forest density and/or area on fisheries?
(Journal article; Peer reviewed, 2013)Kelp forests are highly productive ecosystem engineers of rocky cold-water marine coastlines, providing shelter, habitat and food for a variety of associated organisms. Several factors have been related with an observed ... -
Seasonal and scale-dependent variability in nutrient- and allelopathy-mediated macrophyte-phytoplankton interactions
(Journal article; Peer reviewed, 2013)macrophyte–phytoplankton interactions were investigated using a dual laboratory and field approach during a growing season, with responses quantified as changes in biomass. Short-term, close-range interactions in laboratory ... -
Climate warming feedback from mountain birch forest expansion: Reduced albedo dominates carbon uptake
