Low spatial habitat overlap of herbivores in the High Arctic tundra
(Journal article; Peer reviewed, 2024)Herbivores play a crucial role in shaping tundra ecosystems through their effects on vegetation, nutrient cycling, and soil abiotic factors. Understanding their habitat use, co-occurrence, and overlap is therefore essential ... -
Changes in the functional diversity of modern bird species over the last million years
(Journal article; Peer reviewed, 2023)Despite evidence of declining biosphere integrity, we currently lack understanding of how the functional diversity associated with changes in abundance among ecological communities has varied over time and before widespread ... -
Purging and accumulation of genetic load in conservation
(Journal article; Peer reviewed, 2023)Our ability to assess the threat posed by the genetic load to small and declining populations has been greatly improved by advances in genome sequencing and computational approaches. Yet, considerable confusion remains ... -
Effects of cattle grazing on young spruce trees in boreal production forest

Large-scale integrative taxonomy of Swedish grass flies (Diptera, Chloropidae) reveals hitherto unknown complexity of a dark taxon
(Peer reviewed; Journal article, 2024)The study of biodiversity is fundamental to preserving life on Earth but a challenging endeavour due to the taxonomic neglect associated with hyperdiverse lineages. To overcome this problem, we have implemented for the ... -
Immune gene expression and epigenetic potential affect the consumption of risky food by female house sparrows
(Peer reviewed; Journal article, 2024)When organisms move into new areas, they are likely to encounter novel food resources. Even if they are nutritious, these foods can also be risky, as they might be contaminated by parasites. The behavioural immune system ... -
Does urbanisation lead to parallel demographic shifts across the world in a cosmopolitan plant?
(Peer reviewed; Journal article, 2024)Urbanisation is occurring globally, leading to dramatic environmental changes that are altering the ecology and evolution of species. In particular, the expansion of human infrastructure and the loss and fragmentation of ... -
Risks to Norwegian plant health posed by import of plants with soil or other growing media from Europe
(Research report, 2024)Background: The Norwegian Environment Agency (Miljødirektoratet) and the Norwegian Food Safety Authority (Mattilsynet) tasked the Norwegian Scientific Committee for Food and Environment (Vitenskapskomiteen for mat og miljø, ... -
Long-term stability in the circumpolar foraging range of a Southern Ocean predator between the eras of whaling and rapid climate change
(Peer reviewed; Journal article, 2023)Assessing environmental changes in Southern Ocean ecosystems is difficult due to its remoteness and data sparsity. Monitoring marine predators that respond rapidly to environmental variation may enable us to track anthropogenic ... -
Kunnskapsgrunnlag for vurdering av vannkraft i vernede vassdrag – Verdalsvassdraget som pilot
(SINTEF Energi. Rapport, Research report, 2024)NTE har bedt SINTEF Energi og NTNU Vitenskapsmuseet om å gjøre en uavhengig vurdering av hvilket kunnskapsgrunnlag som bør ligge til grunn dersom vernede vassdrag skal vurderes for vannkraftutbygging. Verdalsvassdraget ble ... -

Tracking aquatic animals for fisheries management in European waters
(Journal article; Peer reviewed, 2024)Acoustic telemetry (AT) has emerged as a valuable tool for monitoring aquatic animals in both European inland and marine waters over the past two decades. The European Tracking Network (ETN) initiative has played a pivotal ... -
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, ... -
Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge
(Journal article; Peer reviewed, 2024)Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not ... -

Interspecific competition impacts the occupancy and range limits of two ptarmigan species along the elevation gradient in Norway
(Peer reviewed; Journal article, 2024)Many mountain species are expected to respond to climate change through upslope shifts of their range limits, but competition may restrict or alter this response. Under traditional range-limit theory, it is expected that ... -
Actuarial senescence progresses similarly across sites and species in four boreal orchids
(Peer reviewed; Journal article, 2024)1. Whole-plant senescence, defined as a decrease in individual fitness as an organism grows older, has often been assumed to not occur in plants; however, it has now been detected in a range of plant taxa. Still, reported ... -
Ancestry testing of "Old Tom," a killer whale central to mutualistic interactions with human whalers
(Peer reviewed; Journal article, 2023)Cooperative hunting between humans and killer whales (Orcinus orca) targeting baleen whales was reported in Eden, New South Wales, Australia, for almost a century. By 1928, whaling operations had ceased, and local killer ... -
Species delimitation and phylogenetic relationships of the Prionospio complex (Annelida, Spionidae) in the Northeast Atlantic
(Peer reviewed; Journal article, 2024)The Prionospio complex comprises the most diverse and complex group within the polychaete family Spionidae. The phylogenetic relationships within the group are still poorly understood, and the generic breakdown is unstable. ...
