The importance of the gastrointestinal microbiota (GM) in health and disease is widely recognized. Although less is known in fish than in mammals, advances in molecular techniques, such as 16S rRNA sequencing, have facilitated characterization of fish GM, comprising resident autochthonous and transient allochthonous bacteria. The microbial diversity and composition are strongly influenced by diet. ...

Textural, mineralogical and mineral compositional observations in a suite of Neoproterozoic aillikite and calcite kimberlite dykes from southern West Greenland point to consistent variations in melt major element compositions amongst these silica-undersaturated magma types. The aillikites have notably higher bulk SiO₂/CO₂, H₂O/CO₂ and K₂O compared ...

A newly discovered ca. 1.5 Ga old carbonatite dyke in central West Greenland is characterized by very high contents of rare earth elements (REE), Sr and Ba (up to 12.4 wt% total REE, 14.6 wt% SrO and 12.4 wt% BaO). The dyke occurrence is named ‘Attu carbonatite’ after the nearby village Attu. The carbonatite is primarily composed of carbonate minerals such as Sr-rich calcite (CaCO₃) and ...

Mental health problems are leading cause of disability in Western societies, with a rising proportion due to mental health problems among young people. Employment is beneficial for health and well-being and is a human right for all. Employment is a key goal for individuals with severe mental health problems, and the vocational rehabilitation approach, Individual Placement and Support (IPS), has ...

Northern Norway experienced an intensely snow rich winter in 1997 when settled snow heights reached a record 240 cm at the weather station in Tromsø on April 29th. Numerous avalanches, settlement evacuations, and two fatalities in a destroyed house in the settlement of Breivikeidet left the public exhausted at the end of the winter. The chaotic response to avalanche events during the season demonstrated ...

The Barents Sea is one of the main pathways for warm and saline Atlantic Water (AW) entering the Arctic Ocean. It is an important region where water mass transformation and dense-water production contribute to the Atlantic meridional overturning circulation. Here, we present data from three cruises and nine glider missions conducted between 2019 and 2022 in the northwestern Barents Sea, and compare ...

The continental lithospheric mantle (CLM) beneath the southern margin of the Congo craton has remained elusive, mainly because of the thick Phanerozoic sedimentary cover concealing possible kimberlite and lamproite diatremes. In this study, we explore this lithospheric mantle section using major and trace element compositions of mantle-derived clinopyroxene and garnet xenocrysts from kimberlites of ...

Mitonuclear discordance between species is readily documented in marine fishes. Such discordance may either be the result of past natural phenomena or the result of recent introgression from previously seperated species after shifts in their spatial distributions. Using ancient DNA spanning five millennia, we here investigate the long-term presence of Pacific bluefin tuna (Thunnus orientalis) and ...

Temaet til boken er det norske fellesskapet og hvorvidt det er robust eller resilient. I introduksjonen skriver Aakvaag og Bæck at robusthet kan defineres som evnen til å overleve og hente seg inn igjen etter utfordringer, kriser, press og andre former for sjokk. Hagen skriver i sitt kapittel at den norske modellen består eller faller sammen om forholdet mellom del og helhet og/eller individuell og ...

Utviklinga av folkesongen i Noreg dei siste seksti til sytti åra har vore formidabel. Mellom anna i Noreg og i Sverige er det påvist ei vokal bølge innan folkesong i tiåra før siste hundreårsskiftet (Gjertsen, 1996, s. 2; Åkesson, 2007). Ein kan omtale denne utviklinga i folkesongen som ei endring frå kvardagssong og allemannseige til nærast ein elitekultur (Espeland, 2002). Der visebølga på 1960- ...
