1. Several studies have shown the potential of eDNA-based proxies for plant identification, but little is known about their spatial and temporal resolution. This limits its use for plant biodiversity assessments and monitoring of vegetation responses to environmental changes. Here we calibrate the temporal and spatial plant signals detected with soil eDNA surveys by comparing with a standard visual ...

In this article I will analyse the variants of the melody used for the song Petter Dass wrote around 1690 about the 5th commandment. There exist about 100 variants of this melody in different archives in Norway, but not in Sweden or Denmark. It is possible to follow the melody in oral tradition through the 19th and 18th centuries. We don’t know if the melody dates back to Petter Dass himself, ...

We celebrate Raymond J. Gagné for his contributions to taxonomy of the Mycetophilidae (Diptera), specifically for his forty-one-years-old monograph of Holarctic Trichonta Winnertz, 1864 that is still the primary source used for species identification in the genus. We briefly reflect on his monograph´s impact and demonstrate by use of recent DNA barcode data extracted from BOLD Systems (BOLD) ...

Curated by socio-cultural anthropologist Fuyubi Nakamura, the exhibition entitled A Future for Memory: Art and Life after the Great Japan Earthquake at the Museum of Anthropology at UBC in British Columbia addresses the sociocultural role of art produced in situ in the aftermath of the triple disaster which occurred in the Tōhoku region of northeast Japan in 2011. The exhibition’s curatorial project ...

Late Pliocene and Early Pleistocene epochs 3.6 to 0.8 million years ago had climates resembling those forecasted under future warming. Palaeoclimatic records show strong polar amplification with mean annual temperatures of 11–19 °C above contemporary values. The biological communities inhabiting the Arctic during this time remain poorly known because fossils are rare. Here we report an ancient ...

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 ...

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 ...
