175 years of adaptation: North Scandinavian Sámi reindeer herding between government policies and winter climate variability (1835–2010)
(Journal article; Peer reviewed, 2016)Unmanaged wild reindeer populations tend to follow cyclical behaviour, and domesticatedreindeer populations often show cyclical behaviour, too. In this contribution, we intendto use the long-term development of two areas ... -
3D modelling of non-uniform and turbulent flow in vertical slot fishways
(Journal article; Peer reviewed, 2017)Global stocks of freshwater fish have been on the decline for decades, driven in part by the obstruction of their migration routes by anthropogenic barriers. To mitigate such impacts, fishways have been developed to ... -
A catch-22 conflict: Access to semi-domestic reindeer modulatesEurasian lynx depredation on domestic sheep
(Journal article; Peer reviewed, 2014)Conserving large carnivores in multi-use landscape is a global challenge. In northern Norway the presence of Eurasian lynx (Lynx lynx) conflicts greatly with the current ways of keeping free-grazing, unguarded livestock ... -
A Century of Conservation: The Ongoing Recovery of Svalbard Reindeer
(Peer reviewed; Journal article, 2019)Several caribou and reindeer (Rangifer tarandus) populations have experienced recent population declines, often attributed to anthropogenic stressors such as harvesting, landscape fragmentation, and climate change. Svalbard ... -
A continent-wide search for Antarctic petrel breeding sites with satellite remote sensing
(Peer reviewed; Journal article, 2018)The Antarctic petrel (Thalassoica antarctica) has been identified as a key species for monitoring the status and health of the Southern Ocean and Antarctic ecosystems. Breeding colonies of the Antarctic petrel are often ... -
A stage-structured Bayesian hierarchical model for salmon lice populations at individual salmon farms – Estimated from multiple farm data sets
(Journal article; Peer reviewed, 2017)Salmon farming has become a prosperous international industry over the last decades. Along with growth in the production farmed salmon, however, an increasing threat by pathogens has emerged. Of special concern is the ... -
Accelerating advances in landscape connectivity modelling with the ConScape library
(Peer reviewed; Journal article, 2022)Increasingly precise spatial data (e.g. high-resolution imagery from remote sensing) allow for improved representations of the landscape network for assessing the combined effects of habitat loss and connectivity declines ... -
Activity patterns of wintering Great Skuas Stercorarius skua
(Peer reviewed; Journal article, 2014)Capsule Great Skuas Stercorarius skua wintering in different areas spent different amounts of time in flight (foraging or searching for food) and so may be experiencing different feeding conditions. Aims To compare the ... -
Aerospace mapping of the status and position of northern forest limit
(Peer reviewed; Journal article, 2012)We study changes in the position of the northern forest limit and state of vegetation in the taiga-tundra ecotone through aerial and satellite imagery in the context of climate variability and of the projected advance of ... -
Aggregations of foraging black guillemots (Cepphus grylle) at a sea-ice edge in front of a tidewater glacier
(Peer reviewed; Journal article, 2022)Seabirds in cold biomes sometimes aggregate near glacier fronts and at sea-ice edges to forage. In this note, we report on large aggregations of black guillemots (Cepphus grylle) at the edge of sea ice in front of the ... -
Airborne laser scanning reveals uniform responses of forest structure to moose (Alces alces) across the boreal forest biome
(Peer reviewed; Journal article, 2023)1. The moose Alces alces is the largest herbivore in the boreal forest biome, where it can have dramatic impacts on ecosystem structure and dynamics. Despite the importance of the boreal forest biome in global carbon ... -
All carnivores are not equal in the rural people's view. Should we develop conservation plans for functional guilds or individual species in the face of conflicts?
(Peer reviewed; Journal article, 2019) -
Alpine bullhead (Cottus poecilopus Heckel): a potential refuge for Gyrodactylus salaris Malmberg, 1957 (Monogenea)
(Peer reviewed; Journal article, 2019)The notifiable freshwater pathogen Gyrodactylus salaris Malmberg, 1957 tends to be a generalist in contrast to other monogeneans. Whilst it causes most damage to its primary host, the Atlantic salmon (Salmo salar Linnaeus), ... -
Annual and diel activity cycles of a northern population of the large migratory cyprinid fish asp (Leuciscus aspius)
(Peer reviewed; Journal article, 2022)Little is known about the exact movement parameters of migratory cyprinids listed as conservation priorities. A northern population of predatory asp, listed on the Bern Convention Appendix III, was studied in a near ... -
Arctic avian predators synchronise their spring migration with the northern progression of snowmelt
(Journal article, 2020) -
Arctic greening from warming promotes declines in caribou populations
(Journal article; Peer reviewed, 2017)Themigratory tundra caribou herds in North America follow decadal population cycles, and browsing from abundant caribou could be expected to counteract the current climate-driven expansion of shrubs in the circumpolar ... -
Assessing climatic and spatial variables influencing zooplankton richness for space-for-time predictions
(Peer reviewed; Journal article, 2023)1. The macroecological drivers of freshwater diversity are accredited geographical, spatial and climatic variables, but also to productivity, ecosystem age and landscape history. Locally diversity is also influenced ... -
Assessing the effectiveness of the Ramsar Convention in preserving wintering waterbirds in the Mediterranean
(Journal article, 2020)lthough biological conservation is based on international agreements, its effectiveness depends on how countries implement such recommendations as effective conservation tools. The Ramsar Convention is the oldest international ... -
Assessing the effects of climate on host-parasite interactions: a comparative study of European birds and their parasites
(Journal article; Peer reviewed, 2013)Background: Climate change potentially has important effects on distribution, abundance, transmission and virulence of parasites in wild populations of animals. Methodology/Principal Finding: Here we analyzed paired ... -
