Increasing intensities of Anisakis simplex (Rudolphi, 1809 det. Krabbe, 1878) larvae with weight and sea age in returning adult Atlantic salmon, Salmo salar L., of coastal waters of Norway
(Peer reviewed; Journal article, 2021)Ninety wild Atlantic salmon, Salmo salar L., (1.5–10.3 kg) were caught in the Namsen Fjord near the mouth of River Namsen, mid-Norway, and examined for the presence and distribution of Anisakis simplex (Rudolphi, 1809 det. ... -
Increasing uptake of ecosystem service assessments: best practice check-lists for practitioners in Europe
(Peer reviewed; Journal article, 2024)Aiming at understanding the role of plural values in decision-making, the IPBES Values Assessment defined nature valuation broadly as including biophysical, economic and socio-cultural assessments, including ecosystem ... -
Increasing water temperatures exacerbate the potential for density dependence in juvenile steelhead
(Journal article; Peer reviewed, 2017)We study the potential effects of predicted climate change on the energetic demands of juvenile steelhead (Oncorhynchus mykiss) and their consequences for local population size and structure in Idaho, USA. Projected increases ... -
Index Measuring Land Use Intensity—A Gradient‐Based Approach
(Journal article, 2023)To monitor the changes in the landscape, and to relate these to ecological processes, we need robust and reproducible methods for quantifying the changes in landscape patterns. The main aim of this study is to present, ... -

Indikatorer for økologisk tilstand i våtmark, semi-naturlig mark og naturlig åpne områder under skoggrensa
(NINA Rapport;2336, Research report, 2023)Nybø, S., Kolstad, A.L., Sandvik, H., Bakkestuen, V., Evju, M., Framstad, E., Grainger, M., Jepsen, J.U., Nater, C.R., Speed, J.D.M., Töpper, J.P., Venter, Z., Åström, J., Åström, S.C.H., Bargmann, T., Silvennoinen, H.M. ... -
Individual migration strategy fidelity but no habitat specialization in two congeneric seabirds
(Peer reviewed; Journal article, 2020)Abstract Aim: In migratory species, individuals often use fixed and individual-specific migration strategies, which we term individual migration strategy fidelity (IMSF). Our goal was to test if guillemots have flexible ... -
Individual Movement - Sequence Analysis Method (IM-SAM): characterizing spatio-temporal patterns of animal habitat use across landscapes
(Peer reviewed; Journal article, 2019)We present methodological advances to a recently developed framework to study sequential habitat use by animals using a visually-explicit and tree-based Sequence Analysis Method (SAM), derived from molecular biology and ... -

Individual phenotypic plasticityexplains seasonal variation in sperm morphology in a passerine bird
(Peer reviewed; Journal article, 2018)Background: Spermatozoa display impressive variation in size and form among and within animal species. In birds, comparative evidence suggests that post-copulatory sexual selection resulting from extra-pair copulations is ... -
Individual recognition of Atlantic Salmon using iris biometry
(Peer reviewed; Journal article, 2020)Traditional tagging methods for fishes can have issues relating to both animal welfare and economic costs. Biometric data such as iris patterns can be captured via digital cameras, which allows for non-invasive tagging and ... -
Individual shark profiling: An innovative and environmentally
(Peer reviewed; Journal article, 2018)Most shark-induced human fatalities are followed by widespread and unselective culling campaigns that have limited effectiveness and may have high ecological costs for threatened species. The blanket culling strategy ... -
Individual-Level Memory is Sufficient to Create Spatial Segregation Among Neighboring Colonies of Central Place Foragers
(Peer reviewed; Journal article, 2021)Marine Spatial Planning (MSP) is a relatively new approach to ocean management and has been widely implemented worldwide. Ideally, MSP should be established as a public process that analyzes and distributes human activities ... -
Industry-specific impacts of global drivers in the European Arctic
(Peer reviewed; Journal article, 2024)Natural resource-based industries in the European Arctic operate in an increasingly competitive and globalized Arctic. Knowledge of key drivers and their industrial impacts provide industries, companies, communities, and ... -
Infection by the cestodes Triaenophorus crassus and Diphyllobothrium spp. in a polymorphic whitefish population
(Peer reviewed; Journal article, 2021)The whitefish (Coregonus lavaretus s.l.) stock in Lake Femunden, Norway, includes three morphs: deepwater spawning (D-), river spawning (R-) and shallow water spawning (S-) whitefish. Infections by Diphyllobothrium spp. ... -
Influence of gear switching on recapture of Atlantic salmon (Salmo salar) in catch-and- release fisheries
(Journal article; Peer reviewed, 2016)Anglers that release Atlantic salmon (Salmo salar) in recreational fisheries do so with the intention that the fish will survive and contribute to succeeding generations. In some instances, salmon that are released may be ... -
Influences of migration phenology on survival are size-dependent in juvenile Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2017)Long-distance migratory species can reduce mortality risks by synchronizing the migration event and create confusion by swamping predators with high densities. To reduce confusion, predators are known to primarily select ... -
