<i>Allocetraria madreporiformis</i> is a small, finger-like, fruticose lichen with isolated occurrences in the inner fiord section of the long, straight fiord Wijdefjorden in Svalbard. Several new localities are added and mapped here, and we show that the species is confined to exclusive high-arctic steppe habitats on finetextured, moderately alkaline soil, exposed to wind erosion and aeolian transport ...

Suomen Historiallinen Seura, Oulun Historiaseura ja Saamelaisarkisto järjestivät 21. syyskuuta 2017 Suomi 100-seminaarin Inarin Sajoksessa. Tilaisuuteen kutsuttiin kolme saamentutkijaa esitelmöimään saamelaisten historiasta itsenäisessä Suomessa. Artikkelimme käsittelee sitä, millaisia narratiiveja saamelaisten historiasta tilaisuudessa artikuloitiin ja millaisia vastanarratiiveja Suomen historiaan ...

The Vestertana Group on the Digermul Peninsula, Finnmark, northern Norway, presents one of the few, potentially continuous Ediacaran– Cambrian sections in Scandinavia. Trace fossils provide the main age constraint, with the boundary traditionally placed at the base of the Breidvika Formation. Here, we provide trace-fossil evidence to show that this boundary is at least as low as the third cycle of ...

Examination of Paradulichia-material collected from the Barents Sea during the Mareano cruises indicated that there are clear morphological differences between Paradulichia typica Boeck, 1871 from the Hardangerfjord, W. Norway and Paradulichia spinifera Gurjanova, 1946 from the Arctic. Based on our material and the original descriptions, these differences are the acute ventral parts of the body ...

De arkeologiske undersøkelsene fant sted i slutten av mai og varte i to dager. Det ble sjaktet maskinelt for å få fram profiler av dyrkningslagene. To arkeologer og en gravemaskinfører åpnet sjaktene. Paleobotaniker var én dag i felt og stod for prøveuttakning. I profilen identifiseres tre dyrkingslager. Et ble datert til førromersk jernalder, 400–150 f.Kr., et til vikingtida / tidlig middelalder ...

Biosecurity measures are commonly used to prevent the introduction of non-native species to natural environments globally, yet the efficacy of practices is rarely tested under operational conditions. A voluntary biosecurity measure was trialled in the Norwegian high Arctic following concern that non-native species might be transferred to the region on the footwear of travellers. Passengers aboard ...

I 2017 undersøkte Tromsø Museum en boplass fra eldre steinalder, ett árran fra middelalder og skyteskjul antatt å være samiske, men som viste seg å være av moderne karakter. Boplassen fra steinalder besto av ulike funnkonsentrasjoner og kunne dateres til perioden 8500-8200 f. Kr. Gjenstandsmaterialet var innholdsrikt med kjerner, tangespisser, eneggete spisser, mikrolitter og veldokumentert ...

Environmental DNA (eDNA) analysis is a rapid, non-invasive, cost-efficient biodiversity monitoring tool with enormous potential to inform aquatic conservation and management. Development is ongoing, with strong commercial interest, and new uses are continually being discovered. General applications of eDNA and guidelines for best practice in freshwater systems have been established, but ...

Scratch circles - bedding plane parallel sedimentary structures formed by the passive rotation of a tethered organism into the surrounding sediment - are relatively rare in the geological record. Here new occurrences of scratch circles are described from the Ediacaran-Cambrian Stáhpogieddi Formation, Digermulen Peninsula, Arctic Norway, and from the Ediacaran Nudaus and Urusis formations, Nama Group, ...

DNA barcoding is emerging as a useful tool not only for species identification but also for studying evolutionary and ecological processes. Although plant DNA barcodes do not always provide species-level resolution, the generation of large DNA barcode data sets can provide insights into the mechanisms underlying the generation of species diversity. Here, we study evolutionary processes in taxonomically ...
