Walruses on the Dnieper: new evidence for the intercontinental trade of Greenlandic ivory in the Middle Ages
(Peer reviewed; Journal article, 2022)Mediaeval walrus hunting in Iceland and Greenland—driven by Western European demand for ivory and walrus hide ropes—has been identified as an important pre-modern example of ecological globalization. By contrast, the main ... -
Water chemistry, zooplankton and benthos in small lakes within the distribution area of the rare European pool frog Pelophylax lessonae (Camerano) in Norway
(Journal article; Peer reviewed, 2020)In June 2018, water chemistry, benthos and zooplankton were investigated in 7 small lakes/ ponds within the key area of the European pool frog Pelophylax lessonae (Camerano) in Norway. The geographic distribution of the ... -
The Well and Rituals in Everyday Life – Three Iron Age Wells Excavated in Trøndelag, Norway
(Peer reviewed; Journal article, 2024)In the summer of 2018, three wells were excavated in Brekstad, Ørland, Norway. The wells, all dated to the late first century BC/early first century AD, were refilled with large quantities of wooden objects, animal bones, ... -
What are the effects of herbivore diversity on tundra ecosystems? A systematic review protocol
(Peer reviewed; Journal article, 2022)Background Changes in the diversity of herbivore communities can strongly influence the functioning of northern ecosystems. Different herbivores have different impacts on ecosystems because of differences in their diets, ... -
What are the impacts of reindeer/caribou (Rangifer tarandus L.) on arctic and alpine vegetation? A systematic review
(Peer reviewed; Journal article, 2015)Background:The reindeer (or caribou,Rangifer tarandusL.) has a natural range extending over much of Eurasia’s and North America’s arctic, alpine and boreal zones, yet its impact on vegetation is still unclear. This lack ... -
What could the ‘sea ice machine’ do to its people? On the lateglacial Doggerland, marine foraging, and the colonisation of Scandinavian seascapes
(Journal article; Peer reviewed, 2019)‘Climate’ is rarely experienced directly – contrary to day-to-day ‘weather’ and ‘seasons’ that manifest in landscapes (‘weather-worlds’). This paper elaborates the role of sea ice and sea ice hunting outside the lateglacial ... -
What evidence exists for temporal variability in Arctic terrestrial and freshwater biodiversity throughout the Holocene? A systematic map protocol
(Peer reviewed; Journal article, 2022)Background The Arctic tundra is subject to the greatest climate change-induced temperature rises of any biome. Both terrestrial and freshwater biota are responding to recent climate warming through variability in their ... -
What is the influence of a reduction of planktivorous and benthivorous fish on water quality in temperate eutrophic lakes? A systematic review
(Peer reviewed; Journal article, 2015)Background:In recent decades, many attempts have been made to restore eutrophic lakes through biomanipulation.Reducing the populations of planktivorous and benthivorous fish (either directly or through stocking of piscivorous ... -
What we see is what we get - Seeing Sandhalsan with new "eyes"
(Chapter, 2018)The rock art at Sandhalsan, in Åfjord municipality, has been known since 1931 and has been an important subject for researchers through the years since discovery. Different methods for documentation, different light, ... -
When birds of a feather flock together: Severe genomic erosion and the implications for genetic rescue in an endangered island passerine
(Journal article; Peer reviewed, 2024)The Seychelles magpie-robin's (SMR) five island populations exhibit some of the lowest recorded levels of genetic diversity among endangered birds, and high levels of inbreeding. These populations collapsed during the 20th ... -
When DNA barcoding and morphology mesh: Ceratopogonidae diversity in Finnmark, Norway
(Journal article; Peer reviewed, 2014)DNA barcoding in Ceratopogonidae has been restricted to interpreting the medically and veterinary important members of Culicoides Latreille. Here the technique is utilised, together with morphological study, to interpret ... -
When soft waters becomes softer; drivers of critically low levels of Ca in Norwegian lakes
(Journal article; Peer reviewed, 2017)In this study, we analyzed long-term trends in calcium (Ca) concentrations for 70 Norwegian lakes spanning a broad geographical range and for a wide range of ambient drivers. A striking decline in Ca concentrations was ... -
When standard DNA barcodes do not work for species identifcation: intermixed mitochondrial haplotypes in the Jaera albifrons complex(Crustacea: Isopoda)
(Journal article; Peer reviewed, 2024)Here, we characterise the standard “Folmer region” of the mitochondrial cytochrome c oxidase subunit 1 (CO1) marker and a fragment of nuclear 28S marker in four species of the Jaera albifrons complex. Jaera albifrons (Leach, ... -
Where Styles Meet - What Does it Mean?
(Chapter, 2017)My PhD project focuses on the concept of style in rock art. As in other parts of the world, style has primarily been used as a dating method in Norwegian rock art research. In combination with shoreline dating researchers ... -
Whole-genome sequencing of African dogs provides insights into adaptations against tropical parasites
(Journal article; Peer reviewed, 2017)Natural selection in domestic dogs is of great interest in evolutionary biology since dogs have migrated to every inhabited continent of the world alongside humans, and adapted to diverse environments. Here, we explored ... -
Why do we find dead bumblebees under linden trees?
(Peer reviewed; Journal article, 2022)1. Linden trees (Tilia spp.) have for a long time been associated with bumblebee (Bombus spp.) mortality in Europe and North America. Several explanations have been suggested for this phenomenon. This study aimed to explore ... -
Why don't all species overexploit?
(Peer reviewed; Journal article, 2021)Overexploitation of natural resources is often viewed as a problem characteristic of only the human species. However, any species could evolve a capacity to overexploit its essential resources through natural selection and ...
