The effects of egg incubation temperature and parental cross on the swimming activity of juvenile brown trout Salmo trutta
(Peer reviewed; Journal article, 2023)temperature had carry-over effects on swimming activity of juvenile brown trout, Salmo trutta. Eggs from different crosses involving anadromous and lacustrine-adfluvial parents were incubated under two temperature regimes, ... -
Effects of episodic exposure to high-pH water on survival of Atlantic salmon eggs and juveniles: Results from laboratory and field Studies
(Peer reviewed; Journal article, 2022)Although effects of acidification on salmonidfish are well studied and documented, effects of episodic high pHhave rarely received attention. In the present study, we investigated effects of high‐pH events on Atlantic ... -
Effects of extrinsic and intrinsic factorson parturition and reproductive outputin wolverines
(Peer reviewed; Journal article, 2024)One of the selective advantages of delayed implantation in carnivores is the flexibility to decouple the time between mating and parturition, allowing both to occur when conditions are most favorable. Terrestrial carnivores ... -
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. ... -
Effects of human-induced disturbances and weather on herbivore movement
(Journal article, 2019)Human-caused habitat disturbances and climate change are leading threats to biodiversity. Studying the impacts of human activities on wildlife from a behavioral perspective is a relevant starting point to understand the ... -
Effects of Landscape Characteristics on Annual Survival of Lesser Prairie-Chickens
(Journal article; Peer reviewed, 2018)Agriculture and development have caused landscape change throughout the southwestern Great Plains in the range of the lesser prairie-chicken (Tympanuchus pallidicinctus). Landscape alteration within the lesser prairie-chicken ... -
Effects of leg flags on nest survival of four species of Arctic-breeding shorebirds
(Journal article; Peer reviewed, 2018)Marking wild birds is an integral part of many field studies. However, if marks affect the vital rates or behavior of marked individuals, any conclusions reached by a study might be biased relative to the general population. ... -
Effects of livestock on occurrence of the Vulnerable red panda Ailurus fulgens in Rara National Park, Nepal
(Journal article; Peer reviewed, 2014)The Vulnerable red panda Ailurus fulgens is endemic to the Himalayas. Anthropogenic activities, including deforestation, have degraded the species’ habitat but the effects of livestock have not been examined. We assessed ... -
Effects of mountain biking versus hiking on trails under different environmental conditions
(Peer reviewed; Journal article, 2020)Recreational use of nature areas is increasing worldwide. All trail-based activities have a certain degradation effect on vegetation and soil, and conflicts between conservation values and recreation may occur. Controversy ... -
Effects of patch-burn grazing on breeding density and territory size of Dickcissels
(Journal article; Peer reviewed, 2019)Ongoing habitat loss and intensification of management of remaining grasslands have led to large population declines of grassland songbirds in North America. As an alternative to intensive and homogeneous use of rangelands, ... -
Effects of resource availability and interspecific interactions on Arctic and red foxes' winter use of ungulate carrion in the Fennoscandian low-Arctic tundra
(Peer reviewed; Journal article, 2024)In the Arctic tundra, predators face recurrent periods of food scarcity and often turnto ungulate carcasses as an alternative food source. As important and localized re-source patches, carrion promotes co-occurrence of ... -
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 ... -
Effects of salmon lice Lepeophtheirus salmonis on wild sea trout Salmo trutta—a literature review
(Peer reviewed; Journal article, 2015)Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, ... -
Effects of satellite transmitters on survival in Snowy Owls Bubo scandiacus
(Journal article; Peer reviewed, 2017)The use of tracking devices to monitor birds is extensive, but the effects of such instruments on equipped individuals are still insufficiently taken into account. Here we evaluate potential effects of backpack-mounted ... -
Effects of temperature and precipitation on breeding migrations of amphibian species in southeastern Norway
(Journal article; Peer reviewed, 2016)To reveal the effects of climate, a generalized linear mixedmodelwas used to explore the variation in onset of spawning migration for the two newt species T. cristatus and L. vulgaris in southernNorway.Amphibians are highly ... -
Effects of water level regulation in alpine hydropower reservoirs: an ecosystem perspective with a special emphasis on fish
(Journal article; Peer reviewed, 2017)Sustainable development of hydropower demands a holistic view of potential impacts of water level regulation (WLR) on reservoir ecosystems. Most environmental studies of hydropower have focused on rivers, whereas environmental ... -
Efficiency of a fishway on brown Trout (Salmo trutta) spawning populations
(Journal article, 2019) -
Efficient sampling for ecosystem service supply assessment at a landscape scale
(Journal article; Peer reviewed, 2019)Decision makers and stakeholders need high-quality data to manage ecosystem services (ES) efficiently. Landscape-level data on ES that are of sufficient quality to identify spatial tradeoffs, co-occurrence and hotspots ... -
Egg incubation temperature affects the timing of the Atlantic salmon Salmo salar homing migration
(Journal article; Peer reviewed, 2018)Here, we show that adult Atlantic salmon Salmo salar returned about 2 weeks later from the feeding areas in the North Atlantic Ocean to the Norwegian coast, through a phenotypically plastic mechanism, when they developed ... -
Egg incubation temperature influences the population-specific outmigration rate of juvenile brown trout Salmo trutta
(Peer reviewed; Journal article, 2022)The present experiment tested if temperature during embryogenesis and parental heritage affected the migratory behaviour of young brown trout Salmo trutta. Two parental forms were used, a freshwater resident form and an ...
