Lost in Translation? Multiple Discursive Strategies and the Interpretation of Sustainability in the Norwegian Salmon Farming Industry
(Journal article; Peer reviewed, 2020-04-04)The term ‘sustainability’ is vague and open to interpretation. In this paper we analyze how firms use the term in an effort to make the concept their own, and how it becomes a premise for further decisions, by applying a ... -
Lukket merdsystem - AquaDomen: Effekt på smittedynamikk
(Master thesis, 2012-06-04)Oppdrettsnæringen har blitt kritisert for å ha en negativ innvirkning på omliggende miljø, der smitteoverføring av ulike agens til ville laksepopulasjoner er et stort problem. Det er også reist bekymring ved den genetiske ... -
Lumpfish Cyclopterus lumpus reproduction: Pituitary gene expression, physiological and morphological changes accompanying gonadal maturation
(Journal article; Peer reviewed, 2022)Lumpfish is the most important cleanerfish species in Atlantic salmon farming. Detailed information on the gonadal maturation process is a prerequisite for year-round production of juvenile lumpfish. In the present study ... -
Læreboka si rolle i evolusjonsundervisninga
(Master thesis, 2021-05-31)Evolusjonsteorien er den store samlande ideen i biologivitskapen, og det er derfor viktig at befolkninga generelt har kunnskap om han. Skulen er den staden der det er størst potensiale for at opplysning om denne sentrale ... -
Læring hos biologistudenter: En kvantitativ pilotstudie av læringsmønstre blant førsteårsstudenter i biologi
(Master thesis, 2019-06-21)For studenter er det viktig å ha gode strategier for å lære, ikke bare i studiehverdagen men også for senere deltakelse i arbeidslivet. Innsikt i studenters bruk av læringsstrategier kan danne et grunnlag for utvikling av ... -
Macro and Microstructural Characteristics of North Atlantic Deep-Sea Sponges as Bioinspired Models for Tissue Engineering Scaffolding
(Journal article; Peer reviewed, 2021)Sponges occur ubiquitously in the marine realm and in some deep-sea areas they dominate the benthic communities forming complex biogenic habitats – sponge grounds, aggregations, gardens and reefs. However, deep-sea sponges ... -
Macroecological context predicts species' responses to climate warming
(Journal article; Peer reviewed, 2021)Context-dependencies in species' responses to the same climate change frustrate attempts to generalize and make predictions based on experimental and observational approaches in biodiversity science. Here, we propose ... -
Macromolecular sheets direct the morphology and orientation of plate-like biogenic guanine crystals
(Journal article; Peer reviewed, 2023)Animals precisely control the morphology and assembly of guanine crystals to produce diverse optical phenomena in coloration and vision. However, little is known about how organisms regulate crystallization to produce ... -
Macrozooplankton as feed source for farmed fish - growth, product quality and safety
(Doctoral thesis, 2006-12-14) -
Making predictions in a changing world: The benefits of individual-based ecology
(Peer reviewed; Journal article, 2015-12-17)Ecologists urgently need a better ability to predict how environmental change affects biodiversity. We examine individual-based ecology (IBE), a research paradigm that promises better a predictive ability by using ... -
Making the best of lousy circumstances: The impact of salmon louse Lepeophtheirus salmonis on depth preference of sea trout Salmo trutta
(Journal article; Peer reviewed, 2020)ABSTRACT: Sea trout are known for seeking out sources of freshwater to rid themselves of salmon lice. However, the effect of natural haloclines in fjords on parasite dynamics is not well understood. We tagged 48 naturally ... -
Male mate choice and selectivity in relation to female body size, in the seed beetle Callosobruchus maculatus
(Master thesis, 2019-06-21)Selectivity in mate choice and mating behaviour is a central element of sexual selection, and an important component of evolution in a number of species across the animal kingdom. Mate choice relates to how individuals ... -
Male mate choice and selectivity in relation to female mating status in the seed beetle Callosobruchus maculatus
(Master thesis, 2021-06-01)Sexual selection plays a role in evolution and often follows the pattern where males are fighting to mate, while females are choosy due to their higher gamete investment. Males can also be selective if they have high costs ... -
Male reproductive biology of European hake Merluccius merluccius
(Doctoral thesis, 2010-05-14)The reproductive biology of European hake (Merluccius merluccius) has been studied extensively in the field, but mainly focusing on fecundity regulation in females and its implications for the fishery. The European hake ... -
Mammalian herbivores restrict the altitudinal range limits of alpine plants.
(Journal article; Peer reviewed, 2021)Although rarely experimentally tested, biotic interactions have long been hypothesised to limit low-elevation range boundaries of species. We tested the effects of herbivory on three alpine-restricted plant species by ... -
Management-driven evolution in a domesticated ecosystem
(Peer reviewed; Journal article, 2014-02-12)Millennia of human land-use have resulted in the widespread occurrence of what have been coined ‘domesticated ecosystems’. The anthropogenic imprints on diversity, composition, structure and functioning of such systems are ... -
Managing biodiversity: Impacts of Legal Protection in Mountain Forests of the Himalayas
(Peer reviewed; Journal article, 2018-08-04)Legal protection has been used as means of conserving forests and associated biodiversity in many regions of the world since the eighteenth century. However, most forests in the global south, even those within protected ... -
Mangrove forest extent and status along the Eritrean Red Sea coast
(Master thesis, 2015-10-08)A mangrove forest species and spatial extent study has been conducted in Eritrea to see if there has been mangrove forest area change over the last two decades, and to describe mangrove cover status. GIS, field work data ... -
Mapping benthic ecological diversity and interactions with bottom-contact fishing on the Flemish Cap (northwest Atlantic)
(Journal article; Peer reviewed, 2020)The ecological diversity of benthic invertebrates from bottom trawl surveys was mapped for the Flemish Cap, a plateau of ~200 km radius in the northwest Atlantic. Species density (SpD), the exponential Shannon diversity ... -
Mapping key neuropeptides involved in the melanocortin system in Atlantic salmon (Salmo salar) brain
(Journal article; Peer reviewed, 2023)The melanocortin system is a key regulator of appetite and food intake in vertebrates. This system includes the neuropeptides neuropeptide y (NPY), agouti-related peptide (AGRP), cocaine- and amphetamine-regulated transcript ...
