The cold-adapted polar cod Boreogadus saida, a key species in Arctic ecosystems, is vulnerable to global warming and ice retreat. In this study, 1257 individuals sampled in 17 locations within the latitudinal range of 75–81°N from Svalbard to East Siberian Sea were genotyped with a dedicated suite of 116 single-nucleotide polymorphic loci (SNP). The overall pattern of isolation by distance (IBD) ...

Rapid climate warming is altering Arctic and alpine tundra ecosystem structure and function, including shifts in plant phenology. While the advancement of green up and flowering are well-documented, it remains unclear whether all phenophases, particularly those later in the season, will shift in unison or respond divergently to warming. Here, we present the largest synthesis to our knowledge of ...

The purposes of this study were: 1) to investigate the anaerobic energy contribution during a simulated cross-country (XC) skiing mass-start competition while roller-ski skating on a treadmill; 2) to investigate the relationship between the recovery of the anaerobic energy reserves and performance; and 3) to compare the gross efficiency (GE) method and maximal accumulated oxygen deficit (MAOD) to ...

The aim of this study was to evaluate the potential of diatom (microalgae) biomass as a lice-reducing ingredient in salmon feed. The original hypothesis was based on the fact that polyunsaturated aldehydes (PUAs), e.g. 2-trans, 4-trans decadenial (A3) produced by diatoms can function as grazing deterrents and harm copepod development. Salmon lice (Lepeophtheirus salmonis) is a copepod, and we intended ...

Terrestrial laser scanning (TLS) provides a means of rapid and highly accurate survey of archaeological excavations and structures at landscape scales, and is particularly valuable for documenting tidal environments. Here, the authors use TLS to record tidal fixed fishing structures and a tide mill within the Léguer Estuary at Le Yaudet, in north-west France. As part of a comprehensive resource-exploitation ...

Objective - The aim of this integrative review was to identify facilitators and barriers to patients’ well-being when being cared for in an ICU setting, from the perspective of the patients.<p> <p>Background - To become critically ill and hospitalised in an ICU is a stressful, chaotic event due to the life-threatening condition itself, as well as therapeutic treatments and the environment. A ...

The Fram Strait is the only deep gateway between the Arctic Ocean and the Nordic Seas and thus is a key area to study past changes in ocean circulation and the marine carbon cycle. Here, we study deep ocean temperature, δ18O, carbonate chemistry (i.e., carbonate ion concentration [CO32−]), and nutrient content in the Fram Strait during the late glacial (35,000–19,000 years BP) and the Holocene based ...

The goal of this article is to propose Game World Design and Analysis for Socio-Ecological Systems (GAS), a framework for the design and analysis of game worlds through socio-ecological systems lenses. Game World Design and Analysis for Socio-Ecological Systems invites designers to a structured reflection of their choices regarding game world correspondence with a real or fictional reference system ...

Denne masteroppgaven er en kvalitativ undersøkelse om foresattes erfaringer med alternativ og supplerende kommunikasjon (ASK). Jeg har gjennomført fem intervju av foresatte til barn med autisme som bruker ASK. Jeg ønsket å framskaffe kunnskap om hvordan foresatte erfarte bruk og opplæring av ASK. Barn med autisme kan ha vansker med språk og kommunikasjon, og ASK kan spille en viktig rolle i å støtte ...

Environmental stressors related to climate change and other anthropogenic activities are impacting Arctic marine ecosystems at exceptional rates. Within this context, predicting future scenarios of deep-sea ecosystems and their consequences linked with the fate of coastal areas is a growing need and challenge. We used an existing food-web model developed to represent the outer basin of the Malangen ...
