Acclimation capacity of critical thermal maximum varies among populations: Consequences for estimates of vulnerability
(Peer reviewed; Journal article, 2023)Adaptive plasticity in thermal tolerance traits may buffer organisms against changing temperatures, making such responses of particular interest in the face of global climate change. Although population variation is integral ... -
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 ... -
Can seasonal fire management reduce the risk of carbon loss from wildfires in a protected Guinea savanna?
(Peer reviewed; Journal article, 2022)Fire is fundamental to the functioning of tropical savannas and routinely used as a management tool. Shifting prescribed burning from later to earlier in the growing season has the potential to reduce greenhouse gas ... -
Climate and density-dependence cause changes in adult sex ratio in a large Arctic herbivore
(Journal article; Peer reviewed, 2017)Variation in adult sex ratio (ASR) affects population demography and dynamics of large mammals. The mechanisms behind this variation are largely unclear, but may be partly related to climatic drivers and density dependence ... -
Climate fluctuations and differential survival of bridled and non-bridled Common Guillemots Uria aalge
(Journal article; Peer reviewed, 2012)Climate fluctuations and its effects on ecological processes are evident in most areas worldwide but whether such climatic effects are induced phenotypic plasticity or whether animals adapt to the new environment through ... -
Contributions from terrestrial and marine resources stabilize predator populations in a rapidly changing climate
(Peer reviewed; Journal article, 2021)Climate change has different and sometimes divergent effects on terrestrial and marine food webs, and in coastal ecosystems, these effects are tightly interlinked. Responses of opportunistic coastal predators and scavengers ... -
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 ... -
Effects of pulsed resources on the dynamics of seed consumer populations: a comparative demographic study in wild boar
(Peer reviewed; Journal article, 2021)Mast seeding is a well-known example of pulsed resources in terrestrial ecosystems. Despite the large literature available so far on the effects of mast seeding on the dynamics of seed consumer populations, it remains ... -
Fine-scale dynamics and community stability in boreal peatlands: revisiting a fen and a bog in Sweden after 50 years
(Journal article; Peer reviewed, 2014)Multi‐decadal studies of community and ecosystem dynamics are rare; however, this time frame is most relevant for assessing the impact of anthropogenic influences and climate change on ecosystems. For this reason, we ... -
How do conditions at birth influence early‐life growth rates in wild boar?
(Peer reviewed; Journal article, 2020)Weather conditions and population density individuals experience at birth influence their life-history traits and thereby population dynamics. Early-life individual growth is a key fitness-related trait; however, how it ... -
Impact of an invasive alien plant on litter decomposition along a latitudinal gradient
(Journal article; Peer reviewed, 2018)Invasive alien plant effects on ecosystem functions are often difficult to predict across environmental gradients due to the context-dependent interactions between the invader and the recipient communities. Adopting a ... -
Influence of migratory ungulate management on competitive interactions with resident species in a protected area
(Journal article; Peer reviewed, 2015)Migratory animals can represent links between protected and unprotected parts of their home ranges. Management of such species outside a conservation area can influence species interactions inside the protected zone. This ... -
Large-scale spatiotemporal variation in road mortality of moose: Is it all about population density?
(Journal article; Peer reviewed, 2011)Ungulate‐vehicle collisions (UVC) constitute a widespread and increasing problem in large parts of the world. This has generated an intensive search for mitigating measures, but often based on a weak understanding of the ... -
Later at higher latitudes: large-scale variability in seabird breeding timing and synchronicity
(Journal article; Peer reviewed, 2016-05-28)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 ... -
Moose effects on soil temperatures, tree canopies, and understory vegetation: a path analysis
(Journal article; Peer reviewed, 2018)Large vertebrate herbivores are ubiquitous and increasingly numerous in boreal forests where they are known to influence ecosystems in many ways. However, separating the direct effects of herbivores from their indirect ... -
Reindeer turning maritime: Ice-locked tundra triggers changes in dietary niche utilization
(Journal article; Peer reviewed, 2019)The rapid warming of the Arctic may not only alter species’ abundances and distributions, but likely also the trophic interactions within and between ecosystems. On the high‐arctic tundra, extreme warm spells and associated ... -
Roe deer face competing risks between predators along a gradient in abundance
(Journal article; Peer reviewed, 2013)Mortality rates and patterns are fundamental demographic traits for understanding the dynamics of populations of large herbivores in different environments. Despite the ongoing recovery of large carnivores in Europe and ... -
Sea or summit? Wild reindeer spatial responses to changing high-arctic winters
(Peer reviewed; Journal article, 2021)Because of climate change, wildlife is facing altered environments, including profound shifts in temperature and precipitation regimes. In snow-dominated ecosystems, winter warming and resulting changes in snowpack properties ... -
Subtle foodscape displacement of a native ungulate by free-ranging livestock in a forest agroecosystem
(Journal article; Peer reviewed, 2018)The prevalence of livestock grazing in wildlife area s is increasing. This transformation of ecosys- tems into agroecosystems is concerning because the intr oduction of new species may cause niche displacement of the ... -
Use, selection, and home range properties: complex patterns of individual habitat utilization
(Journal article; Peer reviewed, 2019)Individual patterns of habitat use emerge from behavioral decisions driven by interactions between landscape characteristics and individual traits. Individual traits, such as age and sex, influence the net gain of using ...
