Recovery of benthic algal assemblages from acidification: how long does it take, and is there a link to eutrophication?
(Journal article; Peer reviewed, 2018)Acidification has adversely affected freshwater ecosystems in many areas, and recovery from acidification is often interrupted by acidic events. We lack detailed information about how benthic algae react to short-term ... -
The recovery of European freshwater biodiversity has come to a halt
(Peer reviewed; Journal article, 2023)Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable to biodiversity loss1. Mitigation measures, including wastewater treatment and hydromorphological restoration, have ... -
Red sea urchins (Echinus esculentus) and water flow influence epiphytic macroalgae density
(Journal article; Peer reviewed, 2015)The importance of forests of the kelp Laminaria hyperborea along the Norwegian coast is related to the three dimensional structure that they create together with the associated macroalgae. Today, kelp forests have recovered ... -
Redegjørelse for miljøtilstanden i Grandefjæra ved Ørland flystasjon
(NIVA-rapport;7221, Research report, 2017)Denne undersøkelsen har hatt som mål å gi ny kunnskap om artsmangfoldet og den økologiske tilstanden i Grandefjæra samt beskrive eventuelle påvirkninger fra avrenning fra flyplassen på artsmangfoldet og vannkvaliteten i ... -
Reduced Acid Deposition Leads to a New Start for Brown Trout (Salmo trutta) in an Acidified Lake in Southern Norway
(Journal article; Peer reviewed, 2018)Acid deposition has led to acidification and loss of fish populations in thousands of lakes and streams in Norway. Since the peak in the late 1970s, acid deposition has been greatly reduced and acidified surface waters ... -
Reductive and Oxidative UV Degradation of PFAS - Status, Needs and Future Perspectives
(Peer reviewed; Journal article, 2021)Perfluoroalkyl and polyfluoroalkyl substances (PFASs) consist of a group of environmentally persistent, toxic and bio-accumulative organic compounds of industrial origin that are widely present in water and wastewater. ... -
Reetablering av laks og sjøørret i Svorka
(NIVA-rapport;6630, Research report, 2014)Det skal etableres en plan for reetablering av laks og sjøørret i Svorka, et sidevassdrag til Orkla ved Svorkmo, Orkdal kommune, Sør Trøndelag. Vassdraget har hatt historisk oppgang av laks og sjøørret, med en anadrom ... -
Reevaluating the role of organic matter sources for coastal eutrophication, oligotrophication and ecosystem health
(Journal article; Peer reviewed, 2019)Organic matter (OM) in aquatic systems is either produced internally (autochthonous OM) or delivered from the terrestrial environment (ter-OM). For eutrophication (or the reverse – oligotrophication), the amount of ... -
Regional assessment of the current extent of acidification of surface waters in Europe and North America
(NIVA-rapport;7268, Research report, 2018)The current status of surface water acidification related to air pollution in Europe and North America has been assessed using country reports, monitoring data, critical loads and exceedance data, acid sensitivity and ... -
Regrowth of kelp after removal of sea urchins (Strongylocentrotus droebachiensis)
(NIVA-rapport;7431, Research report, 2019)With few natural predators, green sea urchins (Strongylocentrotus droebachiensis) have grown in numbers, grazed down large kelp forest areas in Northern Norway into urchin barrens. NIVA deployed three underwater cages ... -
Reker i Indre Oslofjord - overvåking i perioden 2000-2014
(Journal article; Peer reviewed, 2016)Her presenteres resultatene av undersøkelser av forekomst av reker på 7 stasjoner i Indre Oslofjord og Drøbaksundet over en periode på 15 år. I alt ble det observert 15 ulike rekearter. Den mest hyppig observerte arten var ... -
Relating environmental pressures to littoral biological water quality indicators in Western Balkan lakes: Can we fill the largest gaps?
(Peer reviewed; Journal article, 2021)Along six transects in each of six lakes across the Western Balkans, we collected data for three groups of littoral biological water quality indicators: epilithic diatoms, macrophytes, and benthic invertebrates. We assessed ... -
Relative impacts of multiple human stressors in estuaries and coastal waters in the North Sea–Baltic Sea transition zone
(Peer reviewed; Journal article, 2020)The objectives of this study are 1) to map the potential cumulative impacts of multiple human activities and stressors on the ecosystems in the transition zone between the North Sea and Baltic Sea, for Danish waters 2) to ... -
Release of chitobiase as an indicator of potential molting disruption in juvenile Daphnia magna exposed to the ecdysone receptor agonist 20-hydroxyecdysone
(Journal article; Peer reviewed, 2017)During arthropod molting, the old exoskeleton is degraded and recycled by the molting fluid. Chitobiase, a major chitinolytic enzyme in the molting fluid, has been widely used as a biomarker to indicate endocrine disruption ... -
Reliability in distribution modeling — A synthesis and step-by-step guidelines for improved practice
(Peer reviewed; Journal article, 2021)Information about the distribution of a study object (e.g., species or habitat) is essential in face of increasing pressure from land or sea use, and climate change. Distribution models are instrumental for acquiring such ... -
Remote, autonomous real‑time monitoring of environmental DNA from commercial fish
