Modeling salmon lice effects on sea trout population dynamics using an individual-based approach
(Peer reviewed; Journal article, 2021)Salmon lice Lepeophtheirus salmonis infestation of sea trout Salmo trutta results in both additional marine mortality and behavioral changes which may contribute to sea trout population decline. For effective management ... -
Modelled drift patterns of fish larvae link coastal morphology to seabird colony distribution
(Journal article; Peer reviewed, 2016-05-13)Colonial breeding is an evolutionary puzzle, as the benefits of breeding in high densities are still not fully explained. Although the dynamics of existing colonies are increasingly understood, few studies have addressed ... -
Modellering av heildekkande utbreiingskart for arter: Bakgrunn, konsept og arbeidsflyt
(NTNU Gjærevollsenteret;1/2024, Research report, 2024)Ei heilskapleg kartlegging av naturverdiar er avgjerande for ei kunnskapsbasert forvalting av natur. Avvegingar mellom naturverdiar og andre samfunnsinteresser kan ikkje gjerast verken på internasjonalt, nasjonalt, regionalt ... -
Modellering av tap av tamrein til rovvilt - en risikomodell
(NINA rapport;819, Research report, 2012)I januar 2011 fikk NINA i oppdrag av Direktoratet for naturforvaltning (DN) å vurdere om tilgjengelige forskningsdata kunne brukes til modellering av risikobasert erstatning for tap av tamrein til rovvilt. Oppdraget ble ... -
Modelling activity of terrestrial insects in different temperature and water availability scenarios
(Master thesis, 2022)Klimaendringer er forventet å endre de ytre omgivelsene til levende organismer. For terrestriske ektoterme dyr vil den kombinerte effekten av høyere temperaturer og endrede nedbørsmøster kunne utgjøre en fundamental ... -
Modelling allometry: Statistical and biological considerations – A reply to Packard
(Journal article; Peer reviewed, 2018)Allometry studies describe how phenotypic traits increase relative to the increase of the size of the organism. Given that the increase in size of an organism is attributable to growth, a multiplicative process, allometric ... -
Modelling the cultivation and bioremediation potential of the kelp Saccharina latissima in close proximity to an exposed salmon farm in Norway
(Journal article; Peer reviewed, 2013)A 3-dimensional hydrodynamic−ecological model system (SINMOD) was used to estimate the full-scale cultivation potential of the brown alga Saccharina latissima in integrated multi-trophic aquaculture (IMTA) with Atlantic ... -
Modelling the dynamics of growth, development and lipid storage in the marine copepod Calanus finmarchicus
(Journal article; Peer reviewed, 2017)Mechanistic models are essential tools for interpreting and predicting the consequences of a changing environment and stressors such as pollution on the life histories of marine organisms. Here, we apply the simple and ... -
Modelling the maintenance of egg polymorphism in avian brood parasites and their hosts
(Journal article, 2012)In avian brood parasitism, egg phenotype plays a key role for both host and parasite reproduction. Several parrotbill species of the genus Paradoxornis are parasitized by the common cuckoo Cuculus canorus, and clear ... -
Modelling thermal preference and fitness consequences in scenarios of decreasing temperature predictability
(Master thesis, 2019)Klimaendringane er venta å auke snittemperaturen, men også variasjon og føreseielegheit i temperatur. Nøyaktige predikasjonar av framtidig førekomst og foredling av artar må difor ta omsyn også til desse faktorane. Fordi ... -
Modelling time to population extinction when individual reproduction is autocorrelated
(Peer reviewed; Journal article, 2017)In nature, individual reproductive success is seldom independent from year to year, due to factors such as reproductive costs and individual heterogeneity. However, population projection models that incorporate temporal ... -
Modulating macrophage phenotypes as a therapeutic strategy in neurodegenerative diseases
(Master thesis, 2018)Macrophages are sentinel cells and are responsible for maintaining homeostasis in tissues and balancing the expression of proinflammatory versus anti-inflammatory factors. In the central nervous system (CNS), the balance ... -
Modulation of membrane lipid composition and homeostasis in salmon hepatocytes exposed to hypoxia and perfluorooctane sulfonamide, given singly or in combination
(Journal article; Peer reviewed, 2014)The relative importance of environmental hypoxia due to global climate change on organismal ability to adapt to chemical insult and/or mechanisms of these responses is not well understood. Therefore, we have studied the ... -
Modulation of neuro-dopamine homeostasis in juvenile female Atlantic cod (Gadus morhua) exposed to polycyclic aromatic hydrocarbons and perfluoroalkyl substances
(Journal article; Peer reviewed, 2019)The dopaminergic effect of PAH and PFAS mixtures, prepared according to environmentally relevant concentrations, has been studied in juvenile female Atlantic cod (Gadus morhua). Benzo[a]pyrene, dibenzothiophene, fluorene, ... -
Modulation of the endocrine system in juvenile Salmon (Salmon salar) by the organophosphates TCEP and TBEP
(Master thesis, 2015)Inappropriate management of pesticides usage may result to environmental pollution with far reaching effects on the reproduction and survival potential of aquatic animals, particularly fish. For example, the use of pesticides ... -
Modulatory effects of extract of Heinsia crinita against fructose/streptozotocin-induced oxidative stress in diabetic rat models
(Peer reviewed; Journal article, 2023)Oxidative stress plays a crucial role in the development of type 2 diabetes and the associated microvascular and cardiovascular complications. In the study, we have investigated the effects of Heinsia crinita (H. crinita) ... -
Molecular adaptations to phosphorus deprivation and comparison with nitrogen deprivation responses in the diatom Phaeodactylum tricornutum
(Journal article; Peer reviewed, 2018)Phosphorus, an essential element for all living organisms, is a limiting nutrient in many regions of the ocean due to its fast recycling. Changes in phosphate (Pi) availability in aquatic systems affect diatom growth and ... -
Molecular and biochemical effect-directed analysis of polluted sediment from the Lagos lagoon (Nigeria) using Atlantic salmon (Salmo salar) as a model
(Master thesis, 2016)As a result of human interventions, such as agricultural, industrial, and mining activities and urbanization, there have been release of vast range of synthetic and natural environmental pollutants, such as persistent ... -
