The high Arctic is considered a pristine environment compared with many other regions in the northern hemisphere. It is becoming increasingly vulnerable to invasion by invasive alien species (IAS), however, as climate change leads to rapid loss of sea ice, changes in ocean temperature and salinity, and enhanced human activities. These changes are likely to increase the incidence of arrival and ...

Arctic copepods are major grazers and vital food for planktivores in polar ecosystems but challenging to observe due to remoteness and seasonal sea ice coverage. Models offer higher spatio-temporal resolution, and individual-based models (IBMs) are useful since they incorporate individual variability which characterizes most copepod populations. Here, we present an IBM of the Arctic copepod Calanus ...

Background Widely adopted criteria suggest using either low handgrip strength or poor chair stand performance to identify probable sarcopenia. However, there are limited direct comparisons of these measures in relation to important clinical endpoints. We aimed to compare associations between these two measures of probable sarcopenia and all-cause mortality. <p><p>Methods Analyses included 7838 ...

The Arctic Ocean in general and the Barents Sea specifically, are highly affected by the human induced carbon dioxide (CO2) emissions and increasing temperatures. Atlantification, caused by an increase in warm Atlantic Water inflow, and polar amplification, caused by a higher impact of the increasing temperatures at high latitudes, have already been observed. Moreover, the Barents Sea has been ...

In March 20223, the sixth synthesis report penned by the International Panel of Climate Change (Lee et al. 2023) was released. As earlier, the assessments are dire reading and yet again witness of trends going into the wrong direction on almost all important accounts; increase in CO2 emissions, underperforming attempts at cutbacks, rising temperatures on a global scale, missed targets, unpaid ...

Summary In the last century, there has been a dramatic increase in chemical production and number and diversity of chemicals produced. Especially, organofluorine chemistry has increased its importance due to applications in pharmaceuticals, agrochemicals, refrigerant gases and in consumer products and industry with fluoropolymers and per- and polyfluoroalkyl substances (PFAS). PFAS are receiving ...

Taxonomic identification of whale bones found during archaeological excavations is problematic due to their typically fragmented state. This difficulty limits understanding of both the past spatio-temporal distributions of whale populations and of possible early whaling activities. To overcome this challenge, we performed zooarchaeology by mass spectrometry on an unprecedented 719 archaeological and ...

Climate change driven increases in permafrost thaw and terrestrial runoff are expected to facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas in the Arctic, potentially increasing Hg exposure of marine food webs. The main aim of this study was to determine the impacts of seasonal riverine inputs on land-ocean Hg transport, zooplankton diet and Hg bioaccumulation ...

Nasjonale myndigheter legger vekt på at tjenestene som utøves i helse- og omsorgstjenesten skal være kunnskapsbaserte.

This article contributes to the litera ture on political agen da-setting on social mediain the local context. Using interviews with local politicians in northern Norway, wediscuss local politicians’ use of soci al media for agenda-setting in between electionsfrom an agency perspective. We ask whether local politicians seek to promote andcontrol the definition of an issue on social media, and whether ...
