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 ... -
Global change and ecosystem connectivity: how geese link fields of central Europe to eutrophication of Arctic freshwaters
(Journal article; Peer reviewed, 2016)Migratory connectivity by birds may mutually affect different ecosystems over large distances. Populations of geese overwintering in southern areas while breeding in high-latitude ecosystems have increased strongly ... -
Insect herbivory strongly modifies mountain birch volatile emissions
(Peer reviewed; Journal article, 2020)Insect herbivory is known to augment emissions of biogenic volatile organic compounds (BVOCs). Yet few studies have quantified BVOC responses to insect herbivory in natural populations in pan-Arctic regions. Here, we assess ... -
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 ... -
Where do the treeless tundra areas of northern highlands fit in the global biome system: toward an ecologically natural subdivision of the tundra biome
(Peer reviewed; Journal article, 2015)According to some treatises, arctic and alpine sub-biomes are ecologically similar, whereas others find them highly dissimilar. Most peculiarly, large areas of northern tundra highlands fall outside of the two recent ...
