Arctic avian predators synchronise their spring migration with the northern progression of snowmelt
(Journal article, 2020) -
Black-legged kittiwakes as messengers of Atlantification in the Arctic
(Journal article; Peer reviewed, 2018)Climate warming is rapidly altering marine ecosystems towards a more temperate state on the European side of the Arctic. However, this “Atlantification” has rarely been confirmed, as long-term datasets on Arctic marine ... -
Cardiac adaptation in hibernating, free-ranging Scandinavian Brown Bears (Ursus arctos
(Journal article; Peer reviewed, 2020)During six months of annual hibernation, the brown bear undergoes unique physiological changes to adapt to decreased metabolic rate. We compared cardiac structural and functional measures of hibernating and active bears ... -
Circadian rhythmicity persists through the Polar night and midnight sun in Svalbard reindeer
(Journal article; Peer reviewed, 2018)Studies of locomotor activity in Svalbard reindeer reported the temporary absence of diel rhythms under Arctic photic conditions. However, using Lomb-Scargle periodogram analyses with high statistical power we found diel ... -
Computer vision enables short- and long-term analysis of Lophelia pertusa polyp behaviour and colour from an underwater observatory
(Peer reviewed; Journal article, 2019)An array of sensors, including an HD camera mounted on a Fixed Underwater Observatory (FUO) were used to monitor a cold-water coral (Lophelia pertusa) reef in the Lofoten-Vesterålen area from April to November 2015. ... -
Contrasting structural complexity diferentiate hunting strategy in an ambush apex predator
(Peer reviewed; Journal article, 2021)Structural complexity is known to influence prey behaviour, mortality and population structure, but the effects on predators have received less attention. We tested whether contrasting structural complexity in two newly ... -
Defining animal welfare standards in hunting: body mass determines thresholds for incapacitation time and flight distance
(Journal article; Peer reviewed, 2018) -
Estimating mortality of small passerine birds colliding with wind turbines
(Peer reviewed; Journal article, 2023)As demand for renewable energy is rising, wind power development is rapidly growing worldwide. In its wake, conficts arise over land use changes converting pristine nature into industrial power plants and its associated ... -
Eurasian lynx fitness shows little variation across Scandinavian human-dominated landscapes
(Peer reviewed; Journal article, 2019)Despite extensive research on the ecology and behavioural adaptations of large carnivores in humandominated landscapes, information about the fitness consequences of sharing landscapes is still limited. We assessed the ... -
European catfsh (Silurus glanis) as a freshwater apex predator drives ecosystem via its diet adaptability
(Journal article; Peer reviewed, 2017)Apex predators play a key role in ecosystem stability across environments but their numbers in general are decreasing. By contrast, European catfish (Silurus glanis), the European freshwater apex predator, is on the increase. ... -
Fine-scale behavioural differences distinguish resource use by ecomorphs in a closed ecosystem
(Journal article, 2016)Temporal differences in habitat use and foraging specialisms between ecomorphs represent aspects of behavioural phenotype that are poorly understood with regard to the origin and maintenance of ecological diversity. We ... -
Genetic and demographic history define a conservation strategy for earth’s most endangered pinniped, the Mediterranean monk seal Monachus monachus
(Peer reviewed; Journal article, 2021)The Mediterranean monk seal (Monachus monachus) is a flagship species for marine conservation, but important aspects of its life history remain unknown. Concerns over imminent extinction motivated a nuclear DNA study of ... -
Hidden treasure of the Gobi: understanding how water limits range use of khulan in the Mongolian Gobi
(Peer reviewed; Journal article, 2020)Most large herbivores in arid landscapes need to drink which constrains their movements and makes them vulnerable to disturbance. Asiatic wild ass or khulan (Equus hemionus) were widespread and abundant throughout the arid ... -
High prevalence of vaterite in sagittal otoliths causes hearing impairment in farmed fish
(Peer reviewed; Journal article, 2016) -
Host specificity drives genetic structure in a freshwater mussel
(Journal article, 2019)Parasites often depend on their hosts for long distance transport, and genetic population structure can be strongly affected by host specificity and dispersal. Freshwater pearl mussel (Margaritifera margaritifera) populations ... -
Human behaviour can trigger large carnivore attacks in developed countries
(Peer reviewed; Journal article, 2016)The media and scientific literature are increasingly reporting an escalation of large carnivore attacks on humans in North America and Europe. Although rare compared to human fatalities by other wildlife, the media often ... -
Integrating data from different survey types for population monitoring of an endangered species: the case of the Eld’s deer
(Peer reviewed; Journal article, 2019)Despite its value for conservation decision-making, we lack information on population abundances for most species. Because establishing large-scale monitoring schemes is rarely feasible, statistical methods that combine ... -
Land‑based foraging by polar bears reveals sexual conflict outside mating season
(Peer reviewed; Journal article, 2024)According to sexual selection theory, the sexes are faced with opposing evolutionary goals. Male fitness benefits from access to females, whereas female fitness is constrained by food resources and safety for themselves ... -
Longest terrestrial migrations and movements around the world
(Peer reviewed; Journal article, 2019)Long-distance terrestrial migrations are imperiled globally. We determined both round-trip migration distances (straight-line measurements between migratory end points) and total annual movement (sum of the distances ... -
Mapping roadless areas in regionswith contrasting human footprint
(Peer reviewed; Journal article, 2024)In an increasingly human- and road-dominated world, the preservation of functional ecosystems has become highly relevant. While the negative ecological impacts of roads on ecosystems are numerous and well documented, ...
