Increased functional diversity warns of ecological transition in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-07)
As temperatures rise, motile species start to redistribute to more suitable areas, potentially affecting the persistence of several resident species and altering biodiversity and ecosystem functions. In the Barents Sea, a hotspot for global warming, marine fish from boreal regions have been increasingly found in the more exclusive Arctic region. Here, we show that this shift in species distribution ...
Building adaptive capacity in a changing arctic by use of technology
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12)
Rapid Arctic warming, manifested as thawing permafrost, loss of coastal sea ice, sea level rise, and climate-related extreme
events, is particularly challenging for Indigenous people relying on wild food to sustain their livelihood and culture. The adoption of
new technologies could provide specific capabilities to confront vulnerabilities associated with fishing and hunting activities, but it
could ...
‘I will learn from it for as long as I live’ – religious reading and functional literacy skills
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-02)
Max Weber claims in his well-known book, The Protestant Ethic and the Spirit of Capitalism, that the emergence of capitalism had its roots in the Protestant work ethic. Becker and Woessmann’s seminal 2009 paper finds that the more likely relationship between Protestantism and economic prosperity runs via literacy. They claim that Protestants unintendedly acquired literacy skills that functioned as ...
Shark discards in selective and mixed-species pelagic longline fisheries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-31)
The conservation status of several pelagic shark species is considered vulnerable with declining populations, yet data on shark fishing mortality remain limited for large ocean regions. Pelagic sharks are increasingly retained by mixed-species fisheries, or are discarded and not reported by selective fisheries for tunas (<i>Thunnus</i> spp.) or swordfish (<i>Xiphias gladius</i>). We estimated the ...
Adaptive niche-based sampling to improve ability to find rare and elusive species: Simulations and field tests
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-27)
<ol>
<li>Sampling efficiency is crucial to overcome the data crisis in biodiversity and to understand what drives the distribution of rare species.</li
<li>Adaptive niche‐based sampling (ANBS) is an iterative sampling strategy that relies on the predictions of species distribution models (SDMs). By predicting highly suitable areas to guide prospection, ANBS could improve the efficiency of sampling ...
Growth and behaviour of blue mussels, a re-emerging polar resident, follow a strong annual rhythm shaped by the extreme high Arctic light regime: Mussels' growth and behavior in Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-14)
Polar regions are currently warming at a rate above the global average. One issue of concern is the consequences on biodiversity in relation to the Northward latitudinal shift in distribution of temperate species. In the present study, lasting almost two years, we examined two phenological traits, i.e. the shell growth and behavioural rhythm of a recently re-established species in the high Arctic, ...
Fatty Acid Composition of the Lipids from Atlantic Salmon—Comparison of Two Extraction Methods without Halogenated Solvents
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-01)
The scope of this paper was to apply two recently developed methods for lipid extraction: the methyl tert-butyl ether (MTBE) method and the BUME method. These two methods do not include halogenated solvents, which makes them less hazardous to the environment, less toxic, and needed in less volume compared to the standard methods for lipid extraction. Fatty acid composition of the lipids from Atlantic ...
Stability of lipids during wet storage of the marine diatom Porosira glacialis under semi-preserved conditions at 4 and 20 °C
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-17)
Cultivation of diatoms may help alleviate the pressure on wild fish stocks for marine nutrient availability in aquaculture feed and for human consumption. However, the lipids in microalgae biomass are easily deteriorated, both trough lipolysis and degradation of polyunsaturated fatty acids (PUFA). Proper storage conditions are therefore necessary to maintain the lipid quality. Additionally, the ...
Changes in Sea-Ice Protist Diversity With Declining Sea Ice in the Arctic Ocean From the 1980s to 2010s
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-06)
The large declines in Arctic sea-ice age and extent over the last decades could have altered the diversity of sea-ice associated unicellular eukaryotes (referred to as sea-ice protists). A time series from the Russian ice-drift stations from the 1980s to the 2010s revealed changes in community composition and diversity of sea-ice protists from the Central Arctic Ocean. However, these observations ...
Power Imbalance and the Dark Side of the Captive Agri-food Supplier–Buyer Relationship
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-19)
This paper highlights the dark side of power imbalance regarding its consequences in agri-food supplier–buyer relationships. We report on findings from two studies. The first study is based on a sample of 105 key informants, while study 2 is based on a sample of 444 key informants, all from the cocoa agri-food supply market of Ghana. While the first study focuses on the antecedents of power imbalance ...
