Behavioral buffering of extreme weather events in a high-Arctic herbivore
(Journal article; Peer reviewed, 2016)As global warming advances, there is a growing concern about the impact of extreme weather events on ecosystems. In the Arctic, more frequent unseasonal warm spells and rain-on- snow events in winter cause changes in ... -
Climate and density-dependence cause changes in adult sex ratio in a large Arctic herbivore
(Journal article; Peer reviewed, 2017)Peeters, B., V. Veiberg, A. Ø. Pedersen, A. Stien, R. J. Irvine, R. Aanes, B.-E. Sæther, O. Strand, and B. B. Hansen. 2017. Climate and density dependence cause changes in adult sex ratio in a large Arctic herbivore. ... -
Climate change induced molting mismatch? Mountain hare abundance reduced by duration of snowcover and predator abundance
(Journal article; Peer reviewed, 2017)In northern latitudes, species that have adapted to snow cover by molting and changing pelage color will be particularly vulnerable to climate change, as predation levels may increase due to a mismatch with background ... -
Combined effects of long-term feeding, population density and vegetation green-up on reindeer demography
(Peer reviewed; Journal article, 2013)Abstract. Large herbivores living in seasonal environments are generally food-limited through density dependence and climatic factors. This may result in starvation and increased mortality in winter and reduced fecundity ... -
Differential barrier and corridor effects of power lines,roads and rivers on moose (Alces alces) movements
(Journal article; Peer reviewed, 2015)uilding new power lines is required to satisfy increasing demands for the transmission of electricity, and at the same time the road network is expanding. To provide guidelines for the routing of new power lines and ... -
Environmental variation as a driver of predator-prey interactions
(Peer reviewed; Journal article, 2014)Animals often face the trade-off of optimizing foraging while limiting predation. In variable and seasonal environments the availability of resources changes spatially and temporally, forcing animals to adapt their spatial ... -
Estimating and managing broad risk of chronic wasting disease spillover among cervid species
(Peer reviewed; Journal article, 2023)The management of infectious wildlife diseases often involves tackling pathogens that infect multiple host species. Chronic wasting disease (CWD) is a prion disease that can infect most cervid species. CWD was detected in ... -
Large carnivore conservation and traditional pastoralism: A case study on bear–reindeer predation mitigation measures
(Peer reviewed; Journal article, 2023)While wildlife and cultural preservation goals can be either complimentary orcounteractive, the goals of large carnivore conservation and traditional pastoralist lifestyles are often at odds. Livestock depredation can ... -
Later at higher latitudes: large-scale variability in seabird breeding timing and synchronicity
(Peer reviewed; Journal article, 2016)In seasonal environments, organisms are expected to optimally schedule reproduction within an annual range of environmental conditions. Latitudinal gradients generate a range of seasonality to which we can expect adaptations ... -
Multiple stressors: modeling the effect of pollution, climate, and predation on viability of a sub-arctic marine bird
(Journal article; Peer reviewed, 2018)Negative effects of long-transported pollutants, such as many persistent organic pollutants (POPs), on seabirds and other top predators have been documented for decades. Yet, the concentrations, and hence, the negative ... -
Occupancy-based monitoring of ungulate prey species in Thailand indicates population stability, but limited recovery
(Peer reviewed; Journal article, 2020)Longitudinal studies of wildlife are urgently needed in South-East Asia to understand population responses to the high poaching pressure that characterizes this region. We monitored population trends and habitat use of ... -
Performance of hunting statistics as spatiotemporal density indices of moose (Alces alces) in Norway
(Peer reviewed; Journal article, 2014)Wildlife managers are often asking for reliable information of population density across larger spatial scales. In this study, we examined the spatiotemporal relationships between moose density as estimated by cohort ... -
Predation or scavenging? Prey body condition influencesdecision-making in a facultative predator, the wolverine
(Journal article; Peer reviewed, 2016)The interaction between predators and their prey is a key factor driving population dynamics and shaping wildlife communities. Most predators will scavenge in addition to killing their own prey, which alters predation ... -
Shifting seasonality of annual growth through ontogeny for red deer at northern latitudes
(Peer reviewed; Journal article, 2023)Large mammals at northern latitudes show annual cycles of body mass gain insummer and body mass loss in winter. The amplitude and seasonal timing of these cycles may vary through ontogeny depending on trade-offs toward ... -
Thermal conditions during embryogenesis influence metabolic rates of juvenile brown trout Salmo trutta
(Peer reviewed; Journal article, 2021)The projected climate change and increase in thermal conditions in northern latitudes over the next 60 yr has the potential to alter the metabolic scope and potential fitness of aquatic ectotherms. Here, we experimentally ... -
Variability in nomadism: environmental gradients modulate the movement behaviors of dryland ungulates
(Journal article; Peer reviewed, 2019)Studying nomadic animal movement across species and ecosystems is essential for better understanding variability in nomadism. In arid environments, unpredictable changes in water and forage resources are known drivers of ...
