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 ... -
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 ... -
Ocean acidification ameliorates harmful effects of warming in primary consumer
(Journal article; Peer reviewed, 2018)Climate change-induced warming and ocean acidification are considered two imminent threats to marine biodiversity and current ecosystem structures. Here, we have for the first time examined an animal's response to a complete ... -
On estimation and identifiability issues of sex-linked inheritance with a case study of pigmentation in Swiss barn owl (Tyto alba)
(Journal article; Peer reviewed, 2014)Genetic evaluation using animal models or pedigree-based models generally assume only autosomal inheritance. Bayesian animal models provide a flexible framework for genetic evaluation, and we show how the model readily can ... -
Phylogeography of the prehensile tailed skink Corucia zebrata on the Solomon Archipelago
(Journal article; Peer reviewed, 2012)The biogeography of islands is often strongly influenced by prior geological events. Corucia zebrata (Squamata: Scincidae) is endemic to the geologically complex Solomon Archipelago in Northern Melanesia. We examined the ... -
Quantitative and qualitative consequences of reduced pollen loads in a mixed-mating plant
(Journal article; Peer reviewed, 2019)Greater pollination intensity can enhance maternal plant fitness by increasing seed set and seed quality as a result of more intense pollen competition or enhanced genetic sampling. We tested experimentally these effects ... -

Rainfall seasonality predicts the germination behaviour of a tropical dry-forest vine
(Journal article; Peer reviewed, 2019)Seed dormancy is considered to be an adaptive strategy in seasonal and/or unpredictable environments because it prevents germination during climatically favorable periods that are too short for seedling establishment. ... -

Reduced sexual size dimorphism in a pipefish population where males do not prefer larger females
(Journal article; Peer reviewed, 2019)Within a species' distribution, populations are often exposed to diverse environ‐ments and may thus experience different sources of both natural and sexual selec‐tion. These differences are likely to impact the balance ... -
Repeatable individual variation in migration timing in two anadromous salmonids and ecological consequences
(Journal article; Peer reviewed, 2020)Consistent individual differences in behavior have been demonstrated for many animals, but there are few studies of consequences of such repeated behavior in the wild. We tested consistency in migration timing to and from ... -
The role of seasonality in shaping the interactions of honeybees with other taxa
(Peer reviewed; Journal article, 2023)The Eltonian niche of a species is defined as its set of interactions with other taxa. How this set varies with biotic, abiotic and human influences is a core question of modern ecology. In seasonal environments, the ... -
Scavenger community structure along an environmental gradient from boreal forest to alpine tundra in Scandinavia
(Journal article; Peer reviewed, 2020)Scavengers can have strong impacts on food webs, and awareness of their role in ecosystems has increased during the last decades. In our study, we used baited camera traps to quantify the structure of the winter scavenger ...
