Lake settlements, particularly crannogs, pose several contradictions—visible yet inaccessible, widespread yet geographically restricted, persistent yet vulnerable. To further our understanding, we developed the integrated use of palaeolimnological (scanning XRF, pollen, spores, diatoms, chironomids, Cladocera, microcharcoal, biogenic silica, SEM-EDS, stable-isotopes) and biomolecular (faecal stanols, ...

Assessing the diet of wild animals reveals valuable information about their ecology and trophic relationships that may help elucidate dynamic interactions in ecosystems and forecast responses to environmental changes. Advances in molecular biology provide valuable research tools in this field. However, comparative empirical research is still required to highlight strengths and potential biases of ...

Hvilken betydning har arealinngrep for reindriftas økologiske og kulturelle bærekraft? Konsekvensene av arealinngrep handler ikke kun om tap av beiteland og produksjon i reindriftsflokken, men også om endringer i samspillet mellom rein og mennesker, beite, og det samiske reindriftssamfunnet. Tap av beiter har betydning for den kulturelle bærekraften ved at færre familiemedlemmer kan delta i driften ...

Ice-free areas are expanding worldwide due to dramatic glacier shrinkage and are undergoing rapid colonization by multiple lifeforms, thus representing key environments to study ecosystem development. It has been proposed that the colonization dynamics of deglaciated terrains is different between surface and deep soils but that the heterogeneity between communities inhabiting surface and deep soils ...

In archaeological hunter-gatherer research, animals are primarily seen as food. Alternatively, they are proposed to serve as symbols and devices for social structuring of human societies. A growing body of literature in humanities and social sciences now looks into the role of animals as social and sentient co-beings. It is becoming increasingly clear that the roles of animals as other-than-food ...

Although microRNAs (miRNAs) contribute to all hallmarks of cancer, miRNA dysregulation in metastasis remains poorly understood. The aim of this work was to reliably identify miRNAs associated with metastatic progression of colorectal cancer (CRC) using novel and previously published nextgeneration sequencing (NGS) datasets generated from 268 samples of primary (pCRC) and metastatic CRC (mCRC; ...

Climate change is expected to cause major shifts in boreal forests which are in vast areas of Siberia dominated by two species of the deciduous needle tree larch (Larix). The species differ markedly in their ecosystem functions, thus shifts in their respective ranges are of global relevance. However, drivers of species distribution are not well understood, in part because paleoecological data ...

The ability to track variation in climate is important for species to persist in a given environment. Lack of responses to both long-term changes and inter-annual variation in climate parameters can result in reduced fitness and population decline. Furthermore, migration strategy can influence the ability to track climatic variation due to the potential to use reliable environmental cues. Here, ...

What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across 16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete DNA and trait databases. We show that postglacial arrival time varies within and between plant growth forms. Further, arrival times were mainly predicted by adaptation to temperature, ...

Markus Fjellström has presented a substantial doctoral work in scientific archaeology, comprising six articles and an 80-page synthesis. The papers were published between 2015 and 2021. For the first time on such a large and systematic scale, these papers and thesis bring together specialists in Sámi and scientific/laborative archaeology to address the early history of the Sámi. The papers are ...
