Bet-hedging across generations can affect the evolution of variance-sensitive strategies within generations
(Journal article; Peer reviewed, 2019)In order to understand how organisms cope with ongoing changes in environmental variability, it is necessary to consider multiple adaptations to environmental uncertainty on different time scales. Conservative bet-hedging ... -
Bevaringsbiologi - Fjellrev i NINA 2005
(NINA rapport;102, Research report, 2005)Fjellrev Alopex lagopus er en av de mest utrydningstruede pattedyr i Norge og det er stort be-hov for kunnskap både om direkte og underliggende årsaker til fjellrevens tilbakegang så vel som mulige tiltak. ”Overvåkningsp ... -
Bevaringsbiologi. Fjellrev i NINA 2006
(NINA rapport;, Research report, 2006)Fjellreven Alopex lagopus er kritisk truet i Fennoskandia. Det er iverksatt overvåking, ulike be-varingstiltak samt forskning for å forklare den vedvarende tilbakegangen i Norge, Sverige og Finland. Denne rapporten oppsummerer ... -
“Beyond being analysts of doom”: scientists on the frontlines of climate action
(Journal article; Peer reviewed, 2023) -
Bio-optical diversity on cold water coral habitats
(Master thesis, 2017)This study aimed to elucidate the bio-optical diversity of cold water coral habitats and to further improve the accuracy and efficiency of seafloor mapping with the use of an Underwater Hyperspectral Imager (UHI). Comparison ... -
Bio-optics and Ecology in Emiliania huxleyi Blooms: Field and Remote Sensing Studies in Norwegian Waters
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:337, Doctoral thesis, 2012) -
Bioaccumulation of arsenic, cadmium, mercury, lead and selenium in the benthic and pelagic food chain of Lake Baikal
(Master thesis, 2011)Increased anthropogenic release of potentially toxic trace elements such as arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb) and selenium (Se) into freshwater ecosystems over the past century has caused much concern. ... -
Bioaccumulation of chemical elements in grey seals (Halichoerus grypus) from the Baltic Sea
(Master thesis, 2011)Concentrations of Ag, As, B, Ba, Bi, Ca, Cd, Ce, Co, Cs, Cu, Dy, Er, Fe, Ga, Ge, Hg, Ho, K, La, Li, Lu, Mg, Mn, Mo, Na, Nd, Ni, P, Pb, Pr, Rb, S, Sb, Se, Si, Sm, Sn, Sr, Tb, Th, Tl, V, W, Y, Yb and Zn in the livers of grey ... -
Bioaccumulation of Fluorotelomer Sulfonates and Perfluoroalkyl Acids in Marine Organisms Living in Aqueous Film-Forming Foam Impacted Waters
(Journal article; Peer reviewed, 2019)The use of aqueous film-forming foams (AFFFs) has resulted in hot spots polluted with poly- and perfluorinated alkyl substances (PFASs). The phase out of long-chained perfluoroalkyl acids (PFAAs) from AFFFs resulted in the ... -
Bioaccumulation potential of bisphenols and benzophenone UV filters: A multiresidue approach in raptor tissues
(Peer reviewed; Journal article, 2020)Environmental exposure to bisphenols and benzophenone UV filters has received considerable attention due to the ubiquitous occurrence of these contaminants in the environment and their potential adverse health effects. The ... -
Bioavailability of Macro and Micronutrients Across Global Topsoils: Main Drivers and Global Change Impacts
(Peer reviewed; Journal article, 2023)Understanding the chemical composition of our planet's crust was one of the biggest questions of the 20th century. More than 100 years later, we are still far from understanding the global patterns in the bioavailability ... -
Biochemical changes in superchilled storage of salmon (Salmo salar) fillets
(Journal article; Peer reviewed, 2018)Biochemical changes of Atlantic salmon (Salmo salar) fillets during superchilled storage were evaluated. Due to the significant differences in ice crystal sizes observed, the biochemical changes were evaluated both at the ... -
Biochemical composition of Hediste diversicolor (OF Müller, 1776) (Annelida: Nereidae) reared on different types of aquaculture sludge
(Peer reviewed; Journal article, 2023)Introduction: Sustainable growth of the salmon aquaculture industry is highly dependent on the availability of new feed resources as well as improved management and utilization of waste streams from production. Polychaetes ... -
Biochemical composition of Hediste diversicolor cultivated on aquaculture sludge and utilization as a potential fish feed resource
(Master thesis, 2021)Kultiveringen av atlantisk laks (Salmo salmar) er helt avhengig av marine ressurser av høy kvalitet som fiskemel og fiskeolje. Begrensinger på tilgangen til disse ressursene tvinger industrien til å utnytte alternative ... -
Biochemical composition of Rhodomonas baltica as a function of the dilution rate during steady rate of growth
(Master thesis, 2013)The algae Rhodomonas baltica, Karsten was cultured in Guillard f-medium with the phosphate concentration reduced to 5 µmol/L. The cultures were diluted at seven different dilution rates corresponding approximately to growth ... -
Biodegradation of oil spill dispersant surfactants in cold seawater
(Journal article; Peer reviewed, 2018)While biodegradation of chemically dispersed oil has been well documented, only a few studies have focused on the degradation of the dispersant compounds themselves. The objective of this study was to determine the ... -
Biodegradation-mediated alterations in acute toxicity of water-accommodated fraction and single crude oil components in cold seawater
(Journal article; Peer reviewed, 2018)Hydrocarbon biodegradation may be slower in cold Arctic than in temperate seawater, and this will affect the toxicity time window of the hydrocarbons. In this study, the acute toxicities of water-soluble phases of ... -
Biodiversity dynamics in urban areas under changing land-uses
(Doctoral theses at NTNU;2021:107, Doctoral thesis, 2021)Ecology goes to town Urbanisation is increasing worldwide, but as urban expansion inevitably happens at the cost of other ecosystems, understanding how this will affect biodiversity is crucial. Especially if we wish to ...
