Conical pots with a plastic entrance cone on the top are a type of fishing gear used to harvest snow crabs (Chionoecetes opilio) in Arctic regions. In this study, we assessed the effect of pot entrance diameter on the catch efficiency of snow crabs. We used catch data collected during sea trials of pots with different entrance cone diameters, and we conducted laboratory experiments where morphological ...

<i>Purpose</i> – The purpose is to understand how attitudes, norms (injunctive and descriptive), and perceived behavioral control (PBC) (capacity and autonomy) influence intention to publish Open Access (OA), and how personal innovativeness in information technology (PIIT) affects attitude and PBC.<p> <p><i>Design/methodology/approach</i> – This study employs an integrated and extended theory of ...

Key messages <ul> <li>Climate change affects communities and livelihoods in fisheries and aquaculture, and efforts to adapt to and mitigate climate change must therefore be humancentred.</li> <li>Climate adaptation strategies must emphasize the need for poverty eradication and food security, in accordance with the Paris Agreement, the United Nations 2030 Agenda for Sustainable Development and ...

It is indisputable that achieving sustainability in the minerals industry requires a holistic approach to innovation that utilizes the breadth of knowledge found outside the industry. While providing a myriad of opportunities, this open approach to innovation would also be challenging in that companies need to have sufficient absorptive capacity, i.e. the ability to ‘recognize’, ‘assimilate’ and ...

Recent Arctic studies contradict a long-held paradigm of winter quiescence by documenting activity at many trophic levels in the marine food web even during the darkest months of winter. Previous studies have failed to identify which species are performing patterns of vertical migrations during polar night in Kongsfjorden (Svalbard). In the present study, acoustic data supplemented by zooplankton ...

This thesis investigates how the unemployment rate affect the sickness-absence in Troms county. For doing so, we set up a model that investigates the causal relationship between labor market tightness and workers absence behavior and the cyclical selecting of employees with bad health during different states of the business cycle. We take advantage of over 230,000 recorded sickness-absences and ...

Feeding studies give an indication about the role and position of species within ecosystems and provide crucial knowledge for management. Traditional methods are based on morphological identification of prey. DNA metabarcoding is a promising tool that allow for identification of specific prey items, also when highly digested. A total of 63 stomachs from three skate species caught in the Barents Sea ...

Brød er en viktig del av det norske kostholdet, og vi spiser i gjennomsnitt 60 kilo brød per person hvert år. Men vi kaster også mye brød, nesten 20 kilo hver person. Dette er jo verken bra for pengeboka eller miljøet, så hvordan kan vi redusere brødsvinnet?

Formålet med denne studien er å undersøke hvilke demografiske faktorer som virker inn på unge konsumenters matkunnskap, og hvordan matkunnskapen påvirker matvalg. Det teoretiske rammeverket er basert på teorien til Vidgen og Gallegos (2014) som er en konseptualisering av matkunnskap, og deler begrepet inn i fire domener; kunnskap om planlegging og handling, valg, tilberedning og konsum. Dette sees ...

Researchers and wildlife managers strive for low bias and high precision (i.e. high accuracy) when estimating animal population sizes. Distance sampling is currently one of the most widely used monitoring methods. However, it relies on strict sampling designs and modeling assumptions that can be difficult to meet in the field. Here, we use data from two sub-populations of non-migratory wild Svalbard ...
