Variations in inter-specific and sex-related niche partitioning in pelagic boobies during their annual cycle
(Peer reviewed; Journal article, 2024)Animals that co-occur in a region (sympatry) may share the same environment (syntopy), and niche differentiation is expected among closely related species competing for resources. The masked booby (Sula dactylatra) and ... -
Using scale-derived estimates of body size in analyses of Atlantic salmon life-history variation: a cautionary note
(Peer reviewed; Journal article, 2024)Measurements of individual body length at different life stages are critical in understanding fish ecology and evolution. Such data can be obtained via back-calculation from measurements of fish scales or by using the size ... -
Using qPCR to Identify Potential Effects of Thermal Conditions during Embryogenesis on Mitochondrial DNA Copy Number in Juvenile Brown Trout Salmo trutta
(Peer reviewed; Journal article, 2024)Changes in the number, structure, and function of mitochondria during the early life stages of animals can play an important role for an organism’s metabolic rate, growth, and health. Previous studies have shown that ... -
Additions to the knowledge of Encyrtidae (Hymenoptera: Chalcidoidea) from Norway, with descriptions of two new species
(Peer reviewed; Journal article, 2024)Two genera of Encyrtidae (Hymenoptera: Chalcidoidea) are for the first time recorded from Norway: Dusmetia Mercet, 1921 and Prionomastix Mayr, 1876. Six new species records for the country are presented, including two newly ... -
Behaviour of anadromous brown trout (Salmo trutta) in a hydropower regulated freshwater system
(Peer reviewed; Journal article, 2023)Many Norwegian rivers and lakes are regulated for hydropower, which afects freshwater ecosystems and anadromous fish species, such as sea trout (Salmo trutta). Lakes are an important feature of many anadromous river systems. ... -
Increased nationwide use of green spaces in Norway during the COVID-19 pandemic
(Peer reviewed; Journal article, 2023)In recent years, there has been growing concern about the decline in human green space use and nature-based recreation in Western countries. While some evidence suggests that the COVID-19 pandemic led to increased recreational ... -
The role of seasonal migration in spatial population synchrony
(Peer reviewed; Journal article, 2023)Spatially synchronized population dynamics are common in nature, and understanding their causes is key for predicting species persistence. A main driver of synchrony between populations of the same species is shared ... -
Selection of a diversionary field and other habitats by large grazing birds in a landscape managed for agriculture and wetland biodiversity
(Peer reviewed; Journal article, 2024)1. Several populations of cranes, geese, and swans are thriving and increasing in modern agricultural landscapes. Abundant populations are causing conservation conflicts, as they may affect agricultural production and ... -
Frameworks for regulating local natural resource use in northern Sweden and northern Norway – A legislative review
(Peer reviewed; Journal article, 2023)Northern Europe is often seen as having a specific relation to nature. In this manuscript, the policy and regulatory frameworks in Norway and Sweden are compared when it comes to the scope for local use that is provided ... -
Integration of a Frost Mortality Scheme Into the Demographic Vegetation Model FATES
(Peer reviewed; Journal article, 2023)Frost is damaging to plants when air temperature drops below their tolerance threshold. The set of mechanisms used by cold-tolerant plants to withstand freezing is called “hardening” and typically take place in autumn to ... -
High pathogenicity avian influenza (H5N1) in Northern Gannets (Morus bassanus): Global spread, clinical signs and demographic consequences
(Peer reviewed; Journal article, 2023)During 2021 and 2022 High Pathogenicity Avian Influenza (HPAI) killed thousands of wild birds across Europe and North America, suggesting a change in infection dynamics and a shift to new hosts, including seabirds. Northern ... -
Blue mussels in western Norway have vanished where in reach of crawling predators
(Peer reviewed; Journal article, 2023)Blue mussels (Mytilus spp.) are declining around the world. In western Norway, they have widely disappeared from rocky shores but still thrive on floating structures. Other refugia are cracks in rocks, exposed sites, and ... -
Wealth of nomads – an exploratory analysis of livestock inequality in the Saami reindeer husbandry
(Peer reviewed; Journal article, 2023)The evolution of political complexity is a perennial issue in humanities and social sciences. While social inequality is pervasive in contemporary human societies, there is a view that livestock, as the primary source of ... -
Recreational anglers in Norway report widespread dislike of invasive pink salmon
(Peer reviewed; Journal article, 2023)Pink salmon have returned to Norwegian rivers at high abundance in recent odd-numbered years (2017, 2019, 2021, 2023), presenting potential threats to native biodiversity and ecosystem services, including major sport fishing ... -
Review on erosion phenomenon, maintenance, and financial calculation of lifetime as an asset for Pelton turbines
(Peer reviewed; Journal article, 2023)Prevention of greenhouse emissionsis the top priority for all countries, which urges them to switch to renewable energy as much as possible. Hydropower is one of the renewables that have high flexibility and at the same ... -
Mapping density, diversity and species-richness of the Amazon tree flora
(Peer reviewed; Journal article, 2023)Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and ... -
Multi-colony tracking of two pelagic seabirds with contrasting flight capability illustrates how windscapes shape migratory movements at an ocean-basin scale
(Peer reviewed; Journal article, 2023)Migration is a common trait among many animals allowing the exploitation of spatiotemporally variable resources. It often implies high energetic costs to cover large distances, for example between breeding and wintering ... -
The cost of research: Lasting effects of capture, surgery and muscle biopsy on brown bear (Ursus arctos) movement and physiology
(Peer reviewed; Journal article, 2023)Animal models are a key component of translational medicine, helping transfer scientific findings into practical applications for human health. A fundamental principle of research ethics involves weighing the benefits of ... -
Wild Mountain reindeer Rangifer tarandus tarandus winter foraging: snow-free areas a key resource for feeding
(Peer reviewed; Journal article, 2023)In a landscape with patchily distributed forage resources, an animal’s distribution may reflect the distribution of the resources if the population is forage-limited in time or space. This may be particularly explicit in ... -
