Kvantitative data ble samlet ... -
Loss of pelagic fish and zooplankton density associated with subglacial upwelling in high Arctic estuaries may be mitigated by benthic habitat expansion following tidewater glacier retreat
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-23)Glacier fronts are hotspots of pelagic productivity due to upwelling of nutrient-rich water. As tidewater glaciers retreat into land, this subglacial circulation will disappear and sedimentation from terrestrial runoff will increase, leading to a decrease in pelagic productivity with a decline in the abundance of fish and zooplankton. We used Billefjorden, a high Arctic fjord with a glacier recently ... -
Bycatch of northern fulmar (Fulmarus glacialis) in Norwegian longline fisheries: Assessing spatiotemporal variations in scale and risk to improve management
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-09)Seabirds are vulnerable to bycatch in longline fisheries but for most species the impacts are largely unknown. To address this knowledge gap, studies can estimate bycatch directly using observations or calculate the theoretical risk of bycatch using overlap indexes. Here we quantify the scale and risk of bycatch of northern fulmar (Fulmarus glacialis) in the Norwegian offshore longline fishery using ... -

Herunder er det studier som peker på at invalidering har negativ effekt for emosjonell ... -
Ghost fishing by self-baited lost, abandoned or discarded pots in snow crab (Chionoecetes opilio) fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-14)Unintended continuous capture or so-called “ghost fishing”, by abandoned, lost, or otherwise discarded fishing gear produces negative environmental impact on marine life and nature conservation. The risk of ghost fishing in pots could be high due to potential self-baiting resulting from mortality of ghost fished catch. Self-baiting may increase ghost fishing by further attracting marine organisms, ... -
Beyond Green Promises: How Concrete Information Sparks Pride and Drives Sustainable Fashion
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-05)This study examines the relationship between trust and pride and their collective influence on sustainable consumption within the fashion industry. We hypothesized that concrete marketing communications would enhance consumer trust, which in turn would directly, and indirectly via increased pride, encourage sustainable consumption intentions. Through an experimental design involving 199 participants, ... -

Taking the beat of the Arctic: are lemming population cycles changing due to winter climate?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-14)Reports of fading vole and lemming population cycles and persisting low populations in some parts of the Arctic have raised concerns about the spread of these fundamental changes to tundra food web dynamics. By compiling 24 unique time series of lemming population fluctuations across the circumpolar region, we show that virtually all populations displayed alternating periods of cyclic/non-cyclic ... -
The rural development trilemma
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-30)Rural public policies are important and contested in many countries. Politicians and administrations often have high ambitions for both spatial policies (e.g. maintaining demography, local work, businesses etc.) technological development (modernisation, increased productivity etc.), while production tend to be limited by markets (as in the case of agricultural productions) or resources (as in e.g. ... -
Redescription of Proteocephalus fallax La Rue, 1911 (Cestoda) and a list of proteocephalid tapeworms of whitefish (Coregonus spp.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-22)Tapeworms of the genus Proteocephalus Weinland, 1858 (Cestoda: Proteocephalidae) are common and widespread intestinal parasites of whitefish (Coregonus spp., Salmonidae: Coregoninae). Previous taxonomic studies, based solely on morphology and inconsistently fixed specimens, concluded that all salmoniform fish, including whitefish, are parasitised by a single euryxenous and highly polymorphic ... -
