Do birds respond to spiral markers on overhead wires of a high-voltage power line? Insights from a dedicated avian radar
(Peer reviewed; Journal article, 2020)Growing human population demands the expansion of the energy transmission grid. Power lines represent a major death hazard for many species, especially birds. Addressing such a human-wildlife conflict requires detailed ... -
Do conservation measures in forest work? A comparison of three area-based conservation tools for wood-living species in boreal forests
(Peer reviewed; Journal article, 2014)Loss of natural forests and decline in forest biodiversity has led to several policy initiatives in recent years. Despite this, the importance of smaller set-asides vs forest reserves for conservation measures is poorly ... -
Do DOM quality and origin affect the uptake and accumulation of lipid-soluble contaminants in coastal filter feeders? An experimental simulation of teflubenzuron exposure to blue mussels
(Peer reviewed; Journal article, 2023)The increased export of terrestrial dissolved organic matter (terrDOM) to coastal marine ecosystems may affect local filter feeders and the local food web via the altered uptake of organic material and associated contaminants. ... -
Do foraging ecology and contaminants interactively predict parenting hormone levels in common eider?
(Peer reviewed; Journal article, 2023)Global climate change is causing abiotic shifts such as higher air and ocean temperatures, and disappearing sea ice in Arctic ecosystems. These changes influence Arctic-breeding seabird foraging ecology by altering prey ... -
Do ingredient and nutrient intake reveal individual dietary specialization in an omnivorous carnivore, the brown bear?
(Peer reviewed; Journal article, 2024)Generalist populations often harbor individual dietary specialists. Whether using a narrower set of resources than the population (= specialization) affects specialists' nutrient intake remains underexplored. We evaluated ... -
‘Do you care about the river?’ A critical discourse analysis and lessons for management of social conflict over Atlantic salmon (Salmo salar) conservation in the case of voluntary stocking in Wales
(Peer reviewed; Journal article, 2019)1. Stakeholders with shared interests in fish conservation often disagree about which specific conservation measures are appropriate, leading to conflicts with sometimes long‐lasting and disruptive social and political ... -
Documenting lemming population change in the Arctic: Can we detect trends?
(Journal article; Peer reviewed, 2019)Lemmings are a key component of tundra food webs and changes in their dynamics can affect the whole ecosystem. We present a comprehensive overview of lemming monitoring and research activities, and assess recent trends ... -
Does Catch-and-Release Angling Alter the Behavior and Fate of Adult Atlantic Salmon During Upriver Migration?
(Journal article; Peer reviewed, 2015)To reproduce, Atlantic Salmon Salmo salar return to freshwater rivers and migrate upriver to spawning areas. This migration is the basis for recreational fisheries, which for conservation reasons are increasingly characterized ... -
Does defoliation frequency and severity influence plant productivity? The role of grazing management and soil nutrients
(Peer reviewed; Journal article, 2020)Rangeland management approaches, including rotational grazing, rely on assumptions about plant growth responses to the intensity, or severity (sward height) plus frequency, of defoliation. We tested these assumptions at ... -
Does lack of evolvability constrain adaptation? If so, on what time scales?
(Chapter, 2023)The relevance of genetic constraints for evolutionary change beyond microevolutionary timescales is debated. The high evolvability of natural populations predicts rapid adaptation, but evolvability is often found to correlate ... -
Does long-term grazing cause cascading impacts on the soil microbiome in mountain birch forests?
(Peer reviewed; Journal article, 2024)In subarctic mountain birch forests, reindeer grazing and moth outbreaks act as important biotic drivers of ecosystem functioning. We investigated how a long-term contrast in reindeer grazing regimes and short-term ... -
Don't mind if I do: Arctic humpback whales respond to winter foraging opportunities before migration
(Peer reviewed; Journal article, 2023)Migration patterns are fundamentally linked to the spatio-temporal distributions of prey. How migrating animals canrespond to changes in their prey’s distribution and abundance remains largely unclear. During the ... -
“Don’t confuse me with facts”—how right wing populism affects trust in agencies advocating anthropogenic climate change as a reality
(Peer reviewed; Journal article, 2021)Everyday public denial of anthropogenically caused climate change (ACC) has complex antecedents and exists on both individual and institutional levels. Earlier research has linked ACC denial to opposition to formal science ... -
Down a hole: missing GPS positions reveal birth dates of an underground denning species, the red fox
(Others, 2021)Global positioning system (GPS) technology is increasingly used to study animal behavior. However, some animals exhibit behaviors that may result in the failure to acquire a GPS position, such as for species with underground ... -
