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 ...
Direct and Indirect Effect via Endophytism of Entomopathogenic Fungi on the Fitness of Myzus persicae and Its Ability to Spread PLRV on Tobacco
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-21)
Aphids are major crop pests that are feeding on plant sap and transmitting plant viruses, thus inducing high yield losses worldwide. As chemical pesticides are decreasingly used in plant protection, fungi that cause disease to insects (entomopathogenic fungi) are one of the promising alternatives. They are commonly applied by spraying plants to protect them against herbivores. When applied, some ...
Global Seafood Demand Growth Differences across Regions, Income Levels, and Time
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-01)
We used an index approach to calculate demand growth for seafood in 107 countries from 1984 to 2013. We used the results to calculate aggregate demand growth by income level, regionally, and globally. While seafood production has more than doubled since the mid-1980s, we showed that global demand for seafood has been higher than the global seafood supply. Demand growth for seafood varies across time, ...
