Annual variation in breeding success in boreal forest grouse: Four decades of monitoring reveals bottom-up drivers to be more important than predation
(Peer reviewed; Journal article, 2022-10-09)Knowledge of the temporal variation in reproductive success and its key driving factors is crucial in predicting animal population persistence. Few studies have examined the effects of a range of explanatory factors operating ... -
Are local plants the best for ecosystem restoration? It depends on how you analyze the data
(Journal article; Peer reviewed, 2017-11-06)One of the key questions in ecosystem restoration is the choice of the seed material for restoring plant communities. The most common strategy is to use local seed sources, based on the argument that many plants are locally ... -
Contrasting patterns of density-dependent selection at different life stages can create more than one fast–slow axis of life-history variation
(Peer reviewed; Journal article, 2020-03-01)There has been much recent research interest in the existence of a major axis of life‐history variation along a fast–slow continuum within almost all major taxonomic groups. Eco‐evolutionary models of density‐dependent ... -
Coprophagy in moose: A first observation
(Peer reviewed; Journal article, 2023-01-06)Coprophagy, the eating of feces, has been documented in a wide range of species but appears to be rare or difficult to detect in deer (Cervidae). Here, we report the first observation of coprophagy in moose Alces alces, ... -
A curated DNA barcode reference library for parasitoids of northern European cyclically outbreaking geometrid moths
(Peer reviewed; Journal article, 2022-11-18)Large areas of forests are annually damaged or destroyed by outbreaking insect pests. Understanding the factors that trigger and terminate such population eruptions has become crucially important, as plants, plant-feeding ... -
Enhancing pollination is more effective than increased conventional agriculture inputs for improving watermelon yields
(Peer reviewed; Journal article, 2020-04-23)Agricultural practices to improve yields in small‐scale farms in Africa usually focus on improving growing conditions for the crops by applying fertilizers, irrigation, and/or pesticides. This may, however, have limited ... -
Gap formation and dynamics after long-term steady state in an old-growth Picea abies stand in Norway: Above- and belowground interactions
(Journal article; Peer reviewed, 2018-11-30)Stand dynamics and the gap initiation prior to gap formation are not well- understood because of its long- term nature and the scarcity of late- successional stands. Reconstruction of such disturbance is normally based on ... -
Genetic changes caused by restocking and hydroelectric dams in demographically bottlenecked brown trout in a transnational subarctic riverine system
(Journal article; Peer reviewed, 2019-04-29)Habitat discontinuity, anthropogenic disturbance, and overharvesting have led to population fragmentation and decline worldwide. Preservation of remaining natural genetic diversity is crucial to avoid continued genetic ... -
Genetic differentiation of Rubus chamaemorus populations in the Czech Republic and Norway after the last glacial period
(Journal article; Peer reviewed, 2018-05-02)The population structure of cloudberry (Rubus chamaemorus L.), collected from Krkonose Mountains (the Czech Republic), continental Norway and Spitsbergen, was examined using microsatellite analyses (SSR). Among 184 ... -
Genetic evidence of female kin clusters in a continuous population of a solitary carnivore, the Eurasian lynx
(Journal article; Peer reviewed, 2018)Large terrestrial carnivores can sometimes display strong family bonds affecting the spatial distribution of related individuals. We studied the spatial genetic relatedness and family structure of female Eurasian lynx, ... -
Genetic substructure and admixture as important factors in linkage disequilibrium-based estimation of effective number of breeders in recovering wildlife populations
(Journal article; Peer reviewed, 2017)The number of effective breeders (Nb) and effective population size (Ne) are population parameters reflective of evolutionary potential, susceptibility to stochasticity, and viability. We have estimated these parameters ... -
Heat stress responses and population genetics of the kelp Laminaria digitata (Phaeophyceae) across latitudes reveal differentiation among North Atlantic populations
(Peer reviewed; Journal article, 2020-08-17)To understand the thermal plasticity of a coastal foundation species across its latitudinal distribution, we assess physiological responses to high temperature stress in the kelp Laminaria digitata in combination with ... -
Loss of species and genetic diversity during colonization: Insights from acanthocephalan parasites in northern European seals
(Peer reviewed; Journal article, 2023-10-19)Studies on host–parasite systems that have experienced distributional shifts, range fragmentation, and population declines in the past can provide information regarding how parasite community richness and genetic diversity ... -
Low genetic variation of invasive Fallopia spp. in their northernmost European distribution range
(Journal article; Peer reviewed, 2017)Knowledge about the reproduction strategies of invasive species is fundamental for effective control. The invasive Fallopia taxa (Japanese knotweed s.l.) reproduce mainly clonally in Europe, and preventing spread of ... -
The lunar nodal phase cycle and winter atmospheric pressure as possible determinants of moth abundance: Analyses of a 30-year time series from South Norway
(Peer reviewed; Journal article, 2022-10-27)According to the plant stress hypothesis, population peaks of herbivores such as moths are caused by plant stress factors that force plants to reallocate stored defensive proteins to transportable and easily digestive ... -
Macronutrient balancing in free-ranging populations of moose
(Peer reviewed; Journal article, 2021-07-15)At northern latitudes, large spatial and temporal variation in the nutritional composition of available foods poses challenges to wild herbivores trying to satisfy their nutrient requirements. Studies conducted in mostly ... -
Moose in our neighborhood: Does perceived hunting risk have cascading effects on tree performance in vicinity of roads and houses?
(Peer reviewed; Journal article, 2022-04-03)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 ... -
Moose selecting for specific nutritional composition of birch places limits on food acceptability
(Journal article; Peer reviewed, 2017-12-20)Despite decades of intense research, it remains largely unsolved which nutritional factors underpin food selection by large herbivores in the wild. We measured nutritional composition of birch foliage (Betula pubescens) ... -
Museum specimens of a landlocked pinniped reveal recent loss of genetic diversity and unexpected population connections
(Peer reviewed; Journal article, 2023-01-18)The Saimaa ringed seal (Pusa hispida saimensis) is endemic to Lake Saimaa in Finland. The subspecies is thought to have originated when parts of the ringed seal population of the Baltic region were trapped in lakes emerging ... -
Plot size matters: Toward comparable species richness estimates across plot-based inventories
(Peer reviewed; Journal article, 2022-06-12)To understand the state and trends in biodiversity beyond the scope of monitoring programs, biodiversity indicators must be comparable across inventories. Species richness (SR) is one of the most widely used biodiversity ...
