Experimental icing affects growth, mortality, and flowering in a high Arctic dwarf shrub
(Peer reviewed; Journal article, 2016)Effects of climate change are predicted to be greatest at high latitudes, with more pronounced warming in winter than summer. Extreme mid-winter warm spells and heavy rain-on-snow events are already increasing in frequency ... -
Genetic variability and structure of the water vole Arvicola amphibius across four metapopulations in northern Norway
(Journal article; Peer reviewed, 2013)Water vole Arvicola amphibius populations have recently experienced severe decline in several European countries as a consequence of both reduction in suitable habitat and the establishment of the alien predator American ... -
Grouping groupers in the Mediterranean: Ecological baselines revealed by ancient proteins
(Peer reviewed; Journal article, 2023)Marine historical ecology provides a means to establish baselines to inform current fisheries management. Groupers (Epinephelidae) are key species for fisheries in the Mediterranean, which have been heavily overfished. ... -
Habitat quality is more important than matrix quality for bird communities in protected areas
(Journal article; Peer reviewed, 2018)Protected areas are meant to preserve native local communities within their boundaries, but they are not independent from their surroundings. Impoverished habitat quality in the matrix might influence the species composition ... -
Higher host plant specialization of root-associated endophytes than mycorrhizal fungi along an arctic elevational gradient
(Peer reviewed; Journal article, 2020)How community-level specialization differs among groups of organisms, and changes along environmental gradients, is fundamental to understanding the mechanisms influencing ecological communities. In this paper, we investigate ... -
Identifying and correcting spatial bias in opportunistic citizen science data for wild ungulates in Norway
(Journal article; Peer reviewed, 2021)Many publications make use of opportunistic data, such as citizen science observation data, to infer large-scale properties of species’ distributions. However, the few publications that use opportunistic citizen science ... -
IIb-RAD-sequencing coupled with random forest classification indicates regional population structuring and sex-specific differentiation in salmon lice (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2022)The aquaculture industry has been dealing with salmon lice problems forming serious threats to salmonid farming. Several treatment approaches have been used to control the parasite. Treatment effectiveness must be optimized, ... -
Inclusion of juvenile stages improves diversity assessment and adds to our understanding of mite ecology – A case study from mires in Norway
(Peer reviewed; Journal article, 2022)Arachnid orders, Mesostigmata, Trombidiformes, and Sarcoptiformes, commonly known as ‘mites’, are abundant in mires, both as adults and as juveniles. However, due to the challenges of identification, the juvenile forms are ... -
Infection by a helminth parasite is associated with changes in DNA methylation in the house sparrow
(Peer reviewed; Journal article, 2022)Parasites can exert strong selective pressures on their hosts and influence the evolution of host immunity. While several studies have examined the genetic basis for parasite resistance, the role of epigenetics in the ... -
Is my study system good enough? A case study for identifying maternal effects
(Journal article; Peer reviewed, 2016)In this paper, we demonstrate how simulation studies can be used to answer questions about identifiability and consequences of omitting effects from a model. The methodology is presented through a case study where ... -
Is there plasticity in developmental instability? The effect of daily thermal fluctuations in an ectotherm
(Journal article; Peer reviewed, 2017)Diversified bet‐hedging (DBH) by production of within‐genotype phenotypic variance may evolve to maximize fitness in stochastic environments. Bet‐hedging is generally associated with parental effects, but phenotypic variation ... -
Lack of sex-specific movement patterns in an alien species at its invasion front - consequences for invasion speed
(Journal article; Peer reviewed, 2016)Efficient targeting of actions to reduce the spread of invasive alien species relies on understanding the spatial, temporal, and individual variation of movement, in particular related to dispersal. Such patterns may differ ... -
Limited decadal growth of mountain birch saplings has minor impact on surrounding tundra vegetation
(Peer reviewed; Journal article, 2022)Temperatures over the Arctic region are increasing at three times the rate of the global average. Consequently, Arctic vegetation is changing and trees are encroaching into the tundra. In this study, we examine the ... -
Many lifetime growth trajectories for a single mammal
(Peer reviewed; Journal article, 2021)Despite their importance in shaping life history tactics and population dynamics, individual growth trajectories have only been rarely explored in the wild because their analysis requires multiple measurements of individuals ... -
Maternal dopamine exposure provides offspring starvation resistance in Daphnia
(Peer reviewed; Journal article, 2022)The neurotransmitter dopamine has been shown to play an important role in modulating behavioral, morphological, and life history responses to food abundance. However, costs of expressing high dopamine levels remain poorly ... -
Mind the wind: microclimate effects on incubation effort of an arctic seabird
(Journal article; Peer reviewed, 2016-02-21)The energetic costs of reproduction in birds strongly depend on the climate experienced during incubation. Climate change and increasing frequency of extreme weather events may severely affect these costs, especially for ... -
Mitochondrial DNA inference between European populations of Tanymastix stagnalis and their glacial survival in Scandinavia
(Journal article; Peer reviewed, 2013)The early observation from 1914 of Tanymastix stagnalis in Norway was not repeated recently, showing a rare and restricted distribution of this species. All four sampled localities were concentrated in the same area of the ... -
Modular chromosome rearrangements reveal parallel and nonparallel adaptation in a marine fish
(Journal article; Peer reviewed, 2019)Genomic architecture and standing variation can play a key role in ecological adaptation and contribute to the predictability of evolution. In Atlantic cod (Gadus morhua), four large chromosomal rearrangements have been ... -
Moose in our neighborhood: Does perceived hunting risk have cascading effects on tree performance in vicinity of roads and houses?
(Peer reviewed; Journal article, 2022)Like large carnivores, hunters both kill and scare ungulates, and thus might indirectly affect plant performance through trophic cascades. In this study, we hypothesized that intensive hunting and enduring fear of humans ... -
No evidence of handling‐induced mortality in Serengeti's African wild dog population
(Journal article; Peer reviewed, 2018)The disappearance of an endangered African wild dog population from Serengeti National Park (SNP) led to international debate centered around one question: were researchers to blame? The “Burrows' hypothesis” postulated ...
