Understanding patterns of colonisation is important for explaining both the distribution of single species and anticipating how ecosystems may respond to global warming. Insular flora may be especially vulnerable because oceans represent severe dispersal barriers. Here we analyse two lake sediment cores from Iceland for ancient sedimentary DNA to infer patterns of colonisation and Holocene vegetation ...

<p>Background - The serotonin receptor 2A (HTR2A) has been described as an important facilitation mediator of spinal nociceptive processing leading to central sensitization (CS) in animal models of chronic pain. However, whether HTR2A single nucleotide variants (SNVs) modulate neuropathic pain states in patients has not been investigated so far. The aim of this study was to elucidate the potential ...

Detailed paleoecological evidence from Arctic Alaska’s past megafauna can help reconstruct paleoenvironmental conditions and can illustrate ecological adaptation to varying environments. We examined a rare, largely articulated and almost complete skeleton of a steppe bison (<i>Bison priscus</i>) recently unearthed in Northern Alaska. We used a multi-proxy paleoecological approach to reconstruct the ...

Based on phylogenetic analyses of the ITS, nuclear large subunit rRNA, mitochondrial small subunit rRNA, and MCM7 genes, species previously treated as <i>Pannaria hispidula</i> and <i>P. isabellina</i> are shown to represent two new Pannariaceae genera, <i>Hispidopannaria</i> and <i>Phormospsora</i>. Each genus forms monophyletic clades, both in multilocus phylogeny and in single gene phylogenies. ...

Sykepleiere må i større grad bidra til å øke kvaliteten på beslutninger som angår pasientens helse. Samvalg skal være det normale i helsetjenesten, og sykepleiere bør derfor få muligheten til å tilegne seg ny kunnskap og utvikle nye ferdigheter. Både i grunnog videreutdanninger samt i spesialist- og primærhelsetjenesten må vi legge vekt på å utvikle sykepleiernes samvalgskompetanse.

This chapter addresses the physical mechanisms behind SAR imaging of oil spills in the open ocean and proceeds with a discussion on the emerging SAR information retrieval techniques for detecting and characterizing these slicks. Section 9.1 covers oil spill information items possibly derived from SAR and limitations of existing methods. Challenges and trade-offs faced by operational service providers ...

<i>Background</i> - Previous studies have reported that organizational structures and cultures in primary health care are obstacles to district nurses doing successful work in health promotion practice (HPP). Because organizational structures are not easily changed, Jean Watson’s Attending Nurse Caring Model (ANCM) was introduced and piloted at a primary health care center in Sweden, aiming to ...

<p>Purpose - The main aim was to evaluate the measurement properties of the Family Needs Questionnaire-Revised (FNQ-R) in family members of individuals living with severe traumatic brain injury (TBI). <p>Methods - A total of 309 family members of individuals with severe TBI from Colombia, Denmark, Mexico, Norway and Spain participated. Rasch analysis of the FNQ-R and its 6 subscales was ...

This article investigates, using a sociology of profession approach, why veterinarians and aqua medicine biologists share jurisdiction in fish health in Norway. I use a five-actor framework to highlight key events in the development of the Norwegian model for inter-professional and cross-sectoral collaboration in fish health. Veterinarians were initially the only profession involved in fish health. ...

<i>Senecio pseudoarnica</i> was first reported from Norway in 2006, based on a surprise find at the outer-coast island of Sandøya in Tromsø, Troms. Originally interpreted as a case of long-distance dispersal from North America, it soon turned out that species had received human help in crossing the Atlantic. Seeds had been imported from Alaska to Balsfjord, Troms, by a garden enthusiast, who had ...
