Stable isotope marking of otoliths duringvaccination: a novel method for mass-marking fish
(Peer reviewed; Journal article, 2014)Tagging or marking of fishes enables the collection of population-based information for ecological research, yet few techniques enable 100% mark detection success. We tested a new mass-marking technique: otolith marking ... -
The risks of learning: confounding detection anddemographic trend when using count-based indices forpopulation monitoring
(Peer reviewed; Journal article, 2014)Theory recognizes that a treatment of the detection process is required to avoid producing biased estimates of population rate of change. Still, one of three monitoring programmes on animal or plant populations is focused ... -
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 ... -
Effects of salmon lice infection on the behaviour of sea trout in the marine phase
(Peer reviewed, 2014)Salmon lice Lepeophtheirus salmonis Krøyer may affect survival and growth of anadromous salmonids through physiological stress and/or behavioural changes. Using acoustic telemetry tracking, we investigated the behaviour ... -
Estimating lichen volume and reindeer winter pasture quality from Landsat imagery
(Peer reviewed; Journal article, 2014)Reindeer and caribou are keystone species in the circumpolar region, and rely on lichens as their main winter forage to survive in some of the most extreme environments on Earth. Lichen mats, however, can be heavily ... -
Effect of mesh size on baited trap catch composition for noble crayfish (Astacus Astacus)
(Peer reviewed; Journal article, 2014)Minimum size is a common management regulation in noble crayfish (Astacus astacus) fisheries. The most used catching method baited traps, catch crayfish down to 50 mm total length (TL). In Norway the minimum size is 95 mm ... -
Numerical responses of saproxylic beetles to rapid increases in dead wood availability following geometrid moth outbreaks in sub-arctic mountain birch forest
(Peer reviewed; Journal article, 2014)Saproxylic insects play an important part in decomposing dead wood in healthy forest ecosystems, but little is known about their role in the aftermath of large-scale forest mortality caused by pest insect outbreaks. We ... -
Feather Corticosterone Levels on Wintering GroundsHave No Carry-Over Effects on Breeding among ThreePopulations of Great Skuas (Stercorarius skua)
(Peer reviewed; Journal article, 2014)Environmental conditions encountered by migratory seabirds in their wintering areas can shape their fitness. However, the underlying physiological mechanisms remain largely unknown as birds are relatively inaccessible ... -
Determinants of grassland primary productionin seasonally-dry silvopastoral systems in Central America
(Peer reviewed; Journal article, 2014)Grassland primary productivity is the function that underpins the majority of the fodder production in cattle-rearing silvopastoral farms. Hence, understanding the factors that determine grassland productivity is ... -
Linking embryonic temperature with adultreproductive investment in Atlantic salmonSalmo salar
(Peer reviewed; Journal article, 2014)The expression of fitness-related traits, such as egg and gonad size, often varies among habitats and exhibits clinal variation along climatic and latitudinal gradients. However, the mechanisms allowing such variations ... -
Resurrection and redescription of Varestrongylus alces (Nematoda; Protostrongylidae), a lungworm of the Eurasian moose (Alces alces), with report on associated pathology
(Peer reviewed; Journal article, 2014)Varestrongylus alces, a lungworm in Eurasian moose from Europe has been considered a junior synonym of Varestrongylus capreoli, in European roe deer, due to a poorly detailed morphological description and the absence of ... -
Confronting and coping with uncertainty in biodiversity research and praxis
(Peer reviewed; Journal article, 2014)This paper summarises discussions in a workshop entitled “exploring uncertainties in biodiversity science, policy and management”. It draws together experiences gained by scientists and scholars when encountering and coping ... -
Embryogenesis and Larval Biology of the Cold-WaterCoral Lophelia pertusa
(Peer reviewed; Journal article, 2014)Cold-water coral reefs form spectacular and highly diverse ecosystems in the deep sea but little is known about reproduction, and virtually nothing about the larval biology in these corals. This study is based on data ... -
An overview of existing raptor contaminant monitoring activitiesin Europe
(Peer reviewed; Journal article, 2014)Biomonitoring using raptors as sentinels can provide early warning of the potential impacts of contaminants on humans and the environment and also a means of tracking the success of associated mitigation measures. ... -
Effects of free-range and confined housing on joint health in a herd of fattening pigs
(Peer reviewed; Journal article, 2014)Background: Free-range housing, in which pigs have access to both indoor and outdoor areas, is mandatory in organic pig production in Europe, but little is known about the effects of this housing on joint health in pigs. ... -
Ecosystem Services and Opportunity Costs Shift SpatialPriorities for Conserving Forest Biodiversity
(Peer reviewed; Journal article, 2014)Inclusion of spatially explicit information on ecosystem services in conservation planning is a fairly new practice. This study analyses how the incorporation of ecosystem services as conservation features can affect ... -
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 ... -
Large scale modelling of salmon lice (Lepeophtheirus salmonis)infection pressure based on lice monitoring data from Norwegian salmonid farms
(Peer reviewed; Journal article, 2014)Infection by parasitic sea lice is a substantial problem in industrial scale salmon farming. To controlthe problem, Norwegian salmonid farms are not permitted to exceed a threshold level of infection ontheir fish, and farms ... -
Environmental variation as a driver of predator-prey interactions
(Peer reviewed; Journal article, 2014)Animals often face the trade-off of optimizing foraging while limiting predation. In variable and seasonal environments the availability of resources changes spatially and temporally, forcing animals to adapt their spatial ... -
Linking public participation in scientific research to the indicators and needs of international environmental agreements
