Bakgrunn: Stadig flere personer med utviklingshemning oppnår høg alder. Endring i adaptiv atferd kan være et tidlig tegn på aldersrelaterte lideleser som Alzheimers sykdom. Studien belyser om screeningsinstrumentet ABDQ kan benyttes av omsorgspersoner for å avdekke endring i adaptiv atferd.<p> <p>Materiale og metode: Undersøkelsen omfatter 87 personer med utviklingshemning som tidligere har ...

Atlantic salmon post-spawners from a population in northern Norway were tagged with data storage tags (N = 773), and the depth use and diving behaviour of recaptured individuals within the coastal zone were examined, both on their outward migration to sea (N = 44) and their return to the natal river after overwintering at sea (N = 34). In addition, the stomach contents of 909 returning adults caught ...

Innebygde finansfunksjoner kan utføre avanserte beregninger i et regneark. Ved å kopiere formler i stedet for å lage dem manuelt, kan en løsning dessuten utvikles raskt. I artikkelen spør vi om det er mindre faglig krevende å løse oppgaver i et regneark enn på papir (ruteark). Vi forsøker å svare på spørsmålet ved å analysere en finansoppgave med Blooms reviderte taksonomi (BRT) for det kognitive ...

Climate change-driven increases in air and sea temperatures are rapidly thawing the Arctic cryosphere with potential for remobilization and accumulation of legacy persistent organic pollutants (POPs) in adjacent coastal food webs. Here, we present concentrations of selected POPs in zooplankton (spatially and seasonally), as well as zoobenthos and sculpin (spatially) from Isfjorden, Svalbard. ...

This paper explores the impact of health communication using smartphones and the outcome of healthier purchases when young Thai consumers shop for groceries. A conjoint experiment was arranged whereby participants (n ¼ 214) purchased grocery using information conveyed via quick response (QR) codes. Results show that a healthy food label, and a good consumer rating on the food’s health, evoked ...

Discrete deterministic age-structured, stage-structured and difference delay equation population models are analysed and compared with respect to stability and nonstationary behaviour. All three models show that species with iteroparous life histories tend to be more stable than species with semelparous life histories which allow us to conclude that this must be a fairly general ecological ...

Interactions involving parasites often account for large proportions of links within aquatic food webs, yet few studies integrate parasites into their food web analyses. This analysis compares three sets of highly resolved food webs that differ in taxa composition, space, and time for a subarctic lake system. Key topological food web metrics, including connectance, linkage density, and mean generality ...

Birds are endothermic homeotherms that regulate internal metabolic heat production to keep a stable body core temperature. Lung ventilation, which is required to obtain oxygen for metabolism, is potentially a large source for heat and water loss. In a polar habitat with low year-round temperatures and scarcity of food in the winter, conservation of heat and water is crucial for survival of the ...

Knowing the metabolic rate of marine mammals is often important as baseline knowledge of their biology and physiology, e.g., to allow ecosystem assessments and estimation of their resource needs and use, and prey requirements. However, our current knowledge of energetics of large cetaceans is limited compared to many smaller cetaceans. Determining the energy expenditure of large free-ranging whales ...

Citizen science is increasingly used to include in ecological monitoring over the past three decades. Web-based applications or smart phones enable citizens to record observations or experiences at larger temporal and spatial scale and provide opportunities for a larger number of citizens to participate in mapping observations. Citizen science can also be used to record, or map observed and experienced ...
