We examine the composition and levels of organic contaminants (PAHs, PCB, HCB) in four sediment cores collected from the Barents Sea. We assess the influence of temporal variations in contaminant supplies and post-depositional reworking on contaminant distribution. Anthropogenic levels of ∑ 12PAH reached 95 ng g⁻¹, higher inventories dominated by BKF were observed at southern stations, ...

Since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to organohalogen compounds (OHCs) in Arctic biota, there has been a considerable number of new Arctic effect studies. Here, we provide an update on the state of the knowledge of OHC, and also include mercury, exposure and/or associated effects in key Arctic marine and terrestrial ...

The Dividalen (Sami: Dieváidvuovdi) valley in Troms county, North Norway, is well known for its old-growth pine forest, a biodiversity hotspot for dead wood-inhabiting fungi and lichens. The majority of the valley is protected within the Upper Dividalen Landscape Conservation Area and National Park. A general conception is that until the mid-nineteenth century when agriculture and forestry entered ...

Extra-pair mating is a common alternative reproductive strategy among socially monogamous bird species, but empirical data on the genetic mating systems of most species are still lacking. Here we present the first parentage study in the Grey-headed Chickadee (<i>Poecile cinctus</i>), a socially monogamous passerine breeding at low densities in the boreal region of the Palaearctic and Nearctic. In a ...

In the last years, the Dataverse project has successfully built an engaged community from universities and organizations from 6 continents, with currently 46 productions sites around the world that host data across all disciplines. This active and growing community has since 2018 created a Consortium to provide scalable support and services to its member Dataverse repositories. This session ...

The number of digital repositories containing publications and datasets on the Arctic region are increasing enormously. Users want relevant information according to their query with minimum interval of time. Scholars are compelled to search the individual repositories to get their desired documents. Open Arctic Research Index (Open ARI), a planned service at UiT - The Arctic University of Norway, ...

Biobanks have evolved, and their governance procedures have undergone important transformations. Our paper examines this issue by focusing on the perspective of the professionals working in management or scientific roles in research-based biobanks, who have an important impact on shaping these transformations. In particular, it highlights that recent advances in molecular medicine and genomic research ...

Slik Plan S har vært presentert så langt kommer den både for raskt og for sent. Trolig er en vei til å redusere gapet å vente med å innføre en del av de strengere tekniske kravene til senere, og innføre dem trinnvis, skriver Jan Erik Frantsvåg.

Persons with Parkinson’s disease have general timing deficits and have difficulties in rhythm discrimination tasks. The basal ganglia, a crucial part of Parkinson’s disease pathology, is believed to play an important role in rhythm and beat processing, with a possible modulation of basal ganglia activity by level of rhythmic complexity. As dysfunction in basal ganglia impacts function in other brain ...

Using fMRI, Hugdahl et al. (2015) reported the existence of a general-domain cortical network during active task-processing which was non-specific to the cognitive task being processed. They labelled this network the extrinsic mode network (EMN). The EMN would be predicted to be negatively, or anti-correlated with the classic default mode network (DMN), typically observed during periods of rest, ...
