Blubber in marine mammals is a multifunctional tissue, serving critical roles in thermoregulation, energy storage, endocrine regulation, and hydrodynamics. By providing insulation against cold, acting as a dense energy reserve, secreting hormones such as leptin to regulate metabolism, and streamlining the body for efficient swimming, blubber supports survival in diverse and often extreme environments. ...

Abstract Purpose. The purpose of the study was to investigate factors predicting migration pattern in moose in Finnmark. Moose has earlier been most numerous in the central and southern part of Norway, but the moose population in Finnmark increased in the 1990’s, and has now reached a more stable state. This makes a study on how the moose behaves in a relatively new habitat of particular ...

Denne studien undersøker om og eventuelt hvordan CO₂-avgiften og den tilhørende kompensasjonsordningen påvirker fiskeflåtens miljømessige, økonomiske og institusjonelle bærekraft. Bakgrunnen for studien er at fiskerinæringen, til tross for økte klimaforpliktelser og gradvis høyere CO₂-avgift, har hatt en økning i utslipp. Samtidig har næringen vært gjenstand for en kompensasjonsordning som reduserer ...

Abstract This study aims to analyze competitive advantage of Novo Nordisk and estimate its per share intrinsic value using discounted cash flow model. In this case study, competitive advantage was accesses by porter’s five forces analysis, VRIO framework, SWOT analysis and supplemented by financial metrics analysis i.e. ROIC and revenue growth for last 10 years (2015-2024). Free cash flow to equity ...

Cetaceans serve as ecosystem engineers and sentinel species for ocean and human health. They are exposed to various anthropogenic stressors, including pollution, noise, human activities, and climate change which contribute to high levels of stress hormones such as glucocorticoids (e.g. cortisol). While stress response mechanisms are vital in the short term, prolonged exposure to stress can have ...

Long-finned pilot whales (Globicephala melas) are widely distributed and abundant throughout the North Atlantic and sightings have appeared to increase in coastal areas in northern Norway over the past decade. However, little is known about the dynamics and ecological drivers of their movements in this region. Therefore, we deployed 11 satellite-linked tags to determine areas of important habitat, ...

Light and photoperiod vary in a predictable manner throughout the daily and annual cycle that is utilized by organisms to direct processes of living. The aquaculture industry applies light to manipulate salmon development, but the effects have not yet been thoroughly investigated in early ontogeny. Here, salmon eggs and larvae were subjected to three different light regimes (continuous dark, continuous ...

Invasive alien species are major drivers of change in social-ecological systems in the world, causing changes not only in ecosystems but also affecting human systems and ecosystem services. In recent years, the Pacific pink salmon (Oncorhynchus gorbuscha) have invaded Norwegian rivers in numbers of thousands, increasing the concerns among managers regarding the impact on Norwegian ecosystems and ...

Abstract Urbanisation alters ecological conditions in ways that can affect avian reproductive strategies, yet its impacts in high-latitude environments remain underexplored. We investigated how breeding phenology and reproductive success in pied flycatchers (Ficedula hypoleuca) vary across an urban–rural gradient in Arctic Norway, using a combination of long-term data (2007–2018) from a rural site ...

Fndc5 is the precursor to irisin, a myokine that is believed to contribute to metabolism and growth regulation. Therefore, irisin could potentially have a stimulatory effect on fish growth in aquaculture. However, the expression and physiological role of irisin in fish is largely unknown. This study aimed to increase the understanding of fndc5/irisin in Rainbow trout (Oncorhynchus mykiss) by ...
