The Black-legged Kittiwake Rissa tridactyla population is declining throughout its North Atlantic range. In Norway, the species is classified as Endangered on the Norwegian Red List. Studies of diet are one important requirement for effective management of any species. Because it is easier to sample, chick diet has often been considered a proxy for adult diet in many seabird studies, but the ...

Et større boplassområde ble funnet i forbindelse med Statens vegvesens ”Reguleringsplan Rv. 17 Tverlandshalvøya” i Bodø kommune, Nordland fylke. Funnene ligger midt i traseen for den nye riksvegen og utgravningene ble konsentrert om to hovedområder: Eidet og Flata. På begge plassene er det boreale gjenstandsfunn i harde bergarter. Det ble også funnet et par gjenstander i slipt skifer. Det ...

The main goals of this sub-project were to evaluate whether interviewing fishers could be an appropriate method to reveal quantities of the bycatches in the Norwegian trawl fisheries, and to describe the knowledge about and the fishermen's attitudes to the bycatch problem. In total 11 crew members on trawlers from a fishing company in Lofoten were interviewed. The data from the interviews showed ...

The global temperature is increasing, and this is affecting the vegetation phenology in many parts of the world. The most prominent changes occur at northern latitudes such as our study area, which is Svalbard, located between 76300N and 80500N. A cloud-free time series of MODIS-NDVI data was processed. The dataset was interpolated to daily data during the 2000–2020 period with a 231.65 m pixel ...

I 2012-2013 ble et chertbrudd fra steinalderen undersøkt utenfor Alta i Finnmark. Undersøkelsen omfattet 1000 m2 av steinbruddet, og 3500 m2 av bosetingsområdene som lå like ved. I tillegg til utgravning ble det gjort eksperimenter med utvinning av chert i bruddet. Resultatene viser at bruddet ble brukt allerede 8400 f.Kr., og at fyrsetting var den viktigste metoden for å bryte chert fra berget. ...

The indigenous religion of the Sámi population came under strong pressure through the Pietist mission effort, which occurred during the first decades of the 18th century in Denmark-Norway. This study focuses on the complex religious situation in the areas of the Northern Norwegian counties of Nordland and Troms. The study uses a spatial approach to map the positions of the different institutions ...

Global warming is a nonlinear process, and temperature may increase in a stepwise manner. Periods of abrupt warming can trigger persistent changes in the state of ecosystems, also called regime shifts. The responses of organisms to abrupt warming and associated regime shifts can be unlike responses to periods of slow or moderate change. Understanding of nonlinearity in the biological responses to ...

Climate fluctuations and its effects on ecological processes are evident in most areas worldwide but whether such climatic effects are induced phenotypic plasticity or whether animals adapt to the new environment through micro‐evolutionary processes is poorly known. In this study we have analyzed long‐term data (22 years) on the relationship between climatic fluctuations and the adult survival of ...

While there are extensive macro‐ and microfossil records of a range of plants and animals from the Quaternary, earthworms and their close relatives amongst annelids are not preserved as fossils and therefore the knowledge of their past distributions is limited. This lack of fossils means that clitellate worms (Annelida) are currently underused in palaeoecological research, even though they can provide ...
