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 ...

Stomach content analyses are a valuable tool in human forensic science to interpret perimortem events. While the identifcation of food components of plant and animal origin has traditionally been conducted by macro- and microscopical approaches in case of incomplete digestion, molecular methods provide the potential to increase sensitivity and taxonomic resolution. In particular, DNA metabarcoding ...

Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, ...

There is an increasing recognition that there is a class of problems that society must solve urgently in the twenty-first century if humanity is to survive into the twentysecond century—the so-called ‘Grand Challenges’. Science policymakers have been active in recognising these challenges and the attendant need to develop new multidisciplinary ways of working. But embracing multidisciplinarity ...

The topic of this article is Väinö Tanner’s views on Sami policies, which are searched from numerous contexts, including his personal career and Nordic Sami policies. Also the discur-sive resources, which he re-produced, are charted. Of the contemporaneous Sami policies, he ad-vocated the Swedish variant, which suited better his agendas in his scholarly production on the Skolt Sami. The origin of ...
