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 ...
RNA profiling identifies novel, photoperiodhistory dependent markers associated with enhanced saltwater performance in juvenile Atlantic salmon
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-08)
Atlantic salmon migrate to sea following completion of a developmental process known as smolting, which establishes a seawater (SW) tolerant phenotype. Smolting is stimulated by exposure to long photoperiod or continuous light (LL) following a period of exposure to short photoperiod (SP), and this leads to major changes in gill ion exchange and osmoregulatory function. Here, we performed an RNAseq ...
Warming and CO2 enhance arctic heterotrophic microbial activity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-20)
Ocean acidification and warming are two main consequences of climate change that can directly affect biological and ecosystem processes in marine habitats. The Arctic Ocean is the region of the world experiencing climate change at the steepest rate compared with other latitudes. Since marine planktonic microorganisms play a key role in the biogeochemical cycles in the ocean it is crucial to ...
Understanding and managing the interactions of impacts from nature-based recreation and climate change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-04)
Disturbance to ecosystems in parks and protected areas from nature-based tourism and recreation is increasing in scale and severity, as are the impacts of climate change—but there is limited research examining the degree to which these anthropogenic disturbances interact. In this perspective paper, we draw on the available literature to expose complex recreation and climate interactions that may ...
Sustainable Business Models: A Systematic Review of Approaches and Challenges in Manufacturing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-12)
Objective: there is an ongoing need for businesses to strive to maintain ideals within environmental, economic, and social values — commonly known as the triple bottom line. Manufacturing as a sector has advanced drastically and the literature on sustainable business models in this sector has emerged. The purpose of this paper is to analyze sustainable business models in manufacturing and the ...
Widespread soil bacterium that oxidizes atmospheric methane
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-08)
Increasing atmospheric methane concentrations contribute significantly to global warming. The only known biological sink for atmospheric methane is oxidation by methane oxidizing bacteria (MOB). Due to the lack of pure cultures, the physiology and metabolic potential of MOB that oxidize atmospheric methane remains a mystery. Here, we report on isolation and characterization of a MOB that can grow ...
Reconciling ecological and engineering design principles for building microbiomes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-28)
Simplified microbial communities, or “benchtop microbiomes,” enable us to manage the profound complexity of microbial ecosystems. Widespread activities aiming to design and control communities result in novel resources for testing ecological theories and also for realizing new biotechnologies. There is much to be gained by reconciling engineering design principles with ecological processes that shape ...
Life above water: small-scale fisheries as a human experience
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-09)
“Life under water” is UN Sustainable Development Goal No. 14, under which small-scale fisheries fall. Yet, most of what is
happening in small-scale fisheries, and certainly those things that are interesting to social scientists, are taking place above
water—on the water and by the water. Small-scale fishers make their living off the fish that swims in the ocean, but they do so
with the lives they ...
Spatial and temporal distributions in the Norwegian cod fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-25)
Fisheries are characterized by variations in space and time. This study investigates the characteristics of seasonality in cod trawl fisheries in two distinct areas: the coast along the northern Norway and the high sea area of the Barents Sea. Catch per unit effort (CPUE) is used to proxy variation in stock abundance. A CPUE function has been estimated in the frequency‐domain framework, to detect ...
