Automated fluvial hydromorphology mapping from airborne remote sensing
(Peer reviewed; Journal article, 2023)Mapping fluvial hydromorphology is an important part of defining river habitat. Mappingvia field sampling or hydraulic modelingis however time consuming, and mappinghydromorphology directly from remote sensing data may ... -
Backcrossing of a capercaillie × black grouse hybrid male in the wild revealed with molecular marker
(Journal article, 2020)The black grouse Lyrurus tetrix and the capercaillie Tetrao urogallus are known to produce hybrids in wild populations. In general, these hybrids are regarded as infertile; however, conclusive evidence that F1-hybrids are ... -
Behaviour and habitat use of first-time migrant Arctic charr: novel insights from a subarctic marine area
(Peer reviewed; Journal article, 2023)Anadromous Arctic charr Salvelinus alpinus is a cold-adapted salmonid that is vul nerable to climate warming and anthropogenic activities including salmon farming, hydropower regulation, and pollution, which poses a ... -
Benthic macroinvertebrates in lake ecological assessment: A review of methods, intercalibration and practical recommendations
(Peer reviewed; Journal article, 2016)Legislation in Europe has been adopted to determine and improve the ecological integrity of inland and coastal waters. Assessment is based on four biotic groups, including benthic macroinvertebrate communities. For lakes, ... -
BioTIME: A database of biodiversity time series for the Anthropocene

Boat disturbance effects on moulting common eiders Somateria mollissima
(Peer reviewed; Journal article, 2020)Ship and boat traffic are increasing sources of disturbance to marine wildlife. During moult, sea ducks are flightless and rely on productive and shallow feeding areas. However, this period coincides with the peak of the ... -
Breeding populations of Marbled Godwits and Willets have high annual survival and strong site fidelity to managed wetlands
(Peer reviewed; Journal article, 2023)The Prairie Pothole Region of central Canada supports a diverse community of breeding waterbirds, but many species have declining populations and the demographic mechanisms driving the declines remain unknown. We conducted ... -
Breeding stage, not sex, affects foraging characteristics in masked boobies at Rapa Nui
(Peer reviewed; Journal article, 2020)Sexual segregation in foraging occurs in some species and populations of boobies (Sulidae), but it is not a general pattern. Sexual segregation in foraging may occur to avoid competition for food, and this competition may ... -
Breeding timed to maximize reproductive success for a migratory songbird: The importance of phenological asynchrony
(Peer reviewed; Journal article, 2016)Phenological advances and trophic mismatches are frequently reported ecological consequences of climate warming. Trophic mismatches occur when phenological responses to environmental conditions differ among trophic levels ... -
Bycatch in local fishery disrupts natural reestablishment of Eurasian otter in western Norway
(Peer reviewed; Journal article, 2020)Lack of proper estimates of nonreported bycatch has made it difficult to evaluate the actual impact of bycatch in many local fisheries. For the Eurasian otter (Lutra lutra), there are no published estimates on the extent ... -
Can cultural ecosystem services contribute to satisfying basic human needs? A case study from the Lofoten archipelago, northern Norway
(Peer reviewed; Journal article, 2020)There is gradual recognition that cultural ecosystem services are critical building blocks for human well-being. Cultural and provisioning services are often intertwined, difficult to separate, and play salient roles in ... -
Can Energy Depletion of Wild Atlantic Salmon Kelts Negotiating Hydropower Facilities Lead to Reduced Survival?
(Peer reviewed; Journal article, 2020)Repeat spawners constitute an important component of Atlantic salmon populations, but survival of post-spawning individuals (kelts) are often compromised by anthropogenic structures such as hydropower plants (HPPs). Potential ... -
Can habitat selection predict abundance?
(Journal article, 2015). Habitats have substantial influence on the distribut ion and abundance of animals. Ani- mals’ selective mo vement yields their habitat use. Animals generally are more abundant in habitats that are selected most strongly. 2. ... -
Can large unmanaged trees replace ancient pollarded trees as habitats for lichenized fungi, non-lichenized fungi and bryophytes?
(Journal article; Peer reviewed, 2017)Management of ancient trees constitutes a major dilemma in the conservation of associated biodiversity. While traditional methods are often advocated, such practices may incur considerable costs and their effects have ... -
The challenges and opportunities of coexisting with wild ungulates in the human-dominated landscapes of Europe's Anthropocene
(Peer reviewed; Journal article, 2020)The cumulative impact of human activities has driven many species into severe declines across the globe. However, the recent focus on conservation optimism has begun to highlight case studies that go against this trend. ... -
Challenges and science-based implications for modern management and conservation of European ungulate populations
(Journal article; Peer reviewed, 2017)Wildlife management systems face growing challenges to cope with increasingly complex interactions between wildlife populations, the environment and human activities. In this position statement, we address the most important ... -
Challenges for transboundary management of a European
(Peer reviewed; Journal article, 2018)Pan-European legislation stimulates international cooperation to overarching challenges of large carnivore management across jurisdictions. We present an analysis for current transboundary brown bear (Ursus arctos) ... -
Circumpolar dynamics of a marine top-predator track ocean warming rates.
(Journal article; Peer reviewed, 2017)Global warming is a nonlinear process, and temperature may increase in a stepwise manner. Periods of abrupt warming can trigger persistent changes in the state of ecosystems, also called regime shifts. The responses of ... -
Classifying grass-dominated habitats from remotely sensed data: The influence of spectral resolution, acquisition time and the vegetation classification system on accuracy and thematic resolution
(Peer reviewed; Journal article, 2020)Detailed maps of vegetation facilitate spatial conservation planning. Such information can be difficult to map from remotely sensed data with the detail (thematic resolution) required for ecological applications. For ... -
Climate and density-dependence cause changes in adult sex ratio in a large Arctic herbivore
(Journal article; Peer reviewed, 2017)Peeters, B., V. Veiberg, A. Ø. Pedersen, A. Stien, R. J. Irvine, R. Aanes, B.-E. Sæther, O. Strand, and B. B. Hansen. 2017. Climate and density dependence cause changes in adult sex ratio in a large Arctic herbivore. ...
