Using Grizzly Bears to Assess Harvest-Ecosystem Tradeoffs in Salmon Fisheries
(Peer reviewed; Journal article, 2012-04-10)Implementation of ecosystem-based fisheries management (EBFM) requires a clear conceptual and quantitative framework for assessing how different harvest options can modify benefits to ecosystem and human beneficiaries. We ... -
Using Merged Pre-Fishery Abundance as a Parameter Evaluating the Status of Atlantic Salmon and Anadromous Brown Trout Populations: A Norwegian Case Study
(Journal article; Peer reviewed, 2022-09-28)Methods used to monitor variation in population sizes in both Atlantic salmon and anadromous brown trout (sea trout) have been widely used in Norway the last 20 years. However, a national management regime, based on ... -
Using Red List species in designating protection status to forest areas: a case study on the problem of spatio-temporal dynamics
(Journal article; Peer reviewed, 2020)Red-listed species are often used as target species in selection of sites for conservation. However, limitations to their use have been pointed out, and here we address the problem of expected high spatio-temporal dynamics ... -
Using species attributes to characterize late-glacial and early-Holocene environments at Kråkenes, western Norway
(Peer reviewed; Journal article, 2019-08-16)Aim: We aim to use species attributes such as distributions and indicator values to reconstruct past biomes, environment, and temperatures from detailed plant‐macrofossil data covering the late glacial to the early Holocene ... -
Utilisation of fish or crab silage protein for cobia (Rachycentron canadum) – effects on digestion, amino acid distribution, growth, fillet composition and storage quality
(Doctoral thesis, 2009-04-17)The present study was carried out to test the ability to utilise fish silage to feed cobia (Rachycentron canadum) in aquaculture in Vietnam. All four experiments of the present study were carried out over 13 months from ... -
Utilization of dietary minerals in Atlantic salmon fed blue mussel silage
(Master thesis, 2021-11-22) -
Utilization of kelp-derived carbon sources by kelp surface-associated bacteria
(Peer reviewed; Journal article, 2011-01)The surfaces of kelp are covered with bacteria that may utilize kelp-produced carbon and thereby contribute significantly to the carbon flux in kelp forest ecosystems. There is scant knowledge about the identity of these ... -
Utilizing multi-objective decision support tools for protected area selection
(Journal article; Peer reviewed, 2023)Establishing and maintaining protected areas (PAs) is a key action in delivering post-2020 biodiversity targets. PAs often need to meet multiple objectives, ranging from biodiversity protection to ecosystem service provision ... -
Utvikling og testing av RNA-probe mot nsP2 (Salmonid alfavirus subtype 2) for bruk på celler og vev
(Master thesis, 2009-06-15)Salmonid alfavirus (SAV) er et virus i familien Togaviridae og forårsaker sykdomsproblemer ved oppdrett av laks (Salmo salar L) og regnbueørret (Oncorhynchus mykiss, Walbaum) i Europa. Det er per i dag kjent at det forekommer ... -
Vaksinering av berggylt (Labrus bergylta) mot Aeromonas salmonicida A-lagstype V og VI
(Master thesis, 2016-06-09)Oppdrettet berggylt brukt som rensefisk for laks ble vaksinert med en divalent vaksine mot Aeromonas salmonicida A-lagstype V og VI. En uvaksinert negativ kontrollgruppe med samme opprinnelse ble fordelt på andre merder i ... -
Validating timing of salmon smolt runs obtained by telemetry studies
(Journal article; Peer reviewed, 2021)Telemetry tags are increasingly used in management to monitor the migration timing of Atlantic salmon smolts (Salmo salar L.). It has been postulated that (1) effects from tagging and handling may alter migration behaviour, ... -
Validation of a species-specific eDNA-based test system for detecting non-indigenous American lobster Homarus americanus
(Master thesis, 2021-11-22) -
The value of size. Bioeconomic consequences of size-dependent pricing and fishing-induced evolution
(Doctoral thesis, 2011-09-02)The influence of fishing on the dynamics of fish stocks is a core element in fisheries management. One of the most notable characteristics in this context is the sizestructure of a fish stock, composed by the individual ... -

Variability in transport of fish eggs and larvae. IV. Interannual variability in larval stage duration of immigrating plaice in the Dutch Wadden Sea
(Peer reviewed; Journal article, 2009-09-18)Larval immigration of plaice Pleuronectes platessa L. into the western Wadden Sea in spring was followed biweekly from 1993 to 2002. For each year (1993 excluded), 150 settling individuals were selected and used for ... -
Variable Number of Tandem Repeats (VNTR) analysis of Flavobacterium psychrophilum from salmonids in Chile and Norway
(Peer reviewed; Journal article, 2015-07-14)Background Flavobacterium psychrophilum causes serious fish diseases such RTFS and BCWD, affecting the aquaculture industry worldwide. Commercial vaccines are not available and control of the disease depends on the use of ... -
Variation in leaf functional traits through the early development of coastal heathland plants
(Master thesis, 2018-12)Seedling recruitment provides a mechanism for re-establishment after fire and is thus key in the life cycle of managed heathland plant species. However, the seedling phase is a vulnerable stage of the plant’s life cycle, ... -
Vegetasjonsendringer i myr og lynghei på Runde i perioden 1928 til 2010
(Master thesis, 2011-06-16)Effektivisering og reformer i landbruket etter andre verdenskrig har ført til at den tradisjonelle bruken av mange kulturlandskap har blitt sterkt redusert. Runde, en øy på kysten av Møre og Romsdal, er et godt eksempel ... -
Vegetation- memory effects and their association with vegetation resilience in global drylands
(Journal article, 2022)Vegetation memory describes the effect of antecedent environmental and ecological conditions on the present ecosystem state and has been proposed as an important proxy for vegetation resilience. In particular, strong ... -
