The accuracy and precision of age determination by dental cementum annuli in four northern cervids
(Peer reviewed; Journal article, 2020-10-23)Individual age is an important element in models of population demographics, but the limitations of the methods used for age determination are not always clear. We used known-age data from moose (Alces alces), red deer ... -
Alien plants, animals, fungi and algae in Norway: an inventory of neobiota
(Journal article; Peer reviewed, 2019-08-03)We present the results of an inventory and status assessment of alien species in Norway. The inventory covered all known multicellular neobiota, 2496 in total, 1039 of which were classified as naturalised. The latter ... -
Behavioral responses of terrestrial mammals to COVID-19 lockdowns
(Peer reviewed; Journal article, 2023-06-08)COVID-19 lockdowns in early 2020 reduced human mobility, providing an opportunity to disentangle its effects on animals from those of landscape modifications. Using GPS data, we compared movements and road avoidance of ... -
Changing contributions of stochastic and deterministic processes in community assembly over a successional gradient
(Journal article; Peer reviewed, 2017)Successional dynamics in plant community assembly may result from both deterministic and stochastic ecological processes. The relative importance of different ecological processes is expected to vary over the successional ... -
Effect of legal regulation of supplemental feeding on space use of red deer in an area with chronic wasting disease
(Peer reviewed; Journal article, 2022-12-12)Supplemental feeding of cervids during winter is a widespread management practice, but feeding may increase the risk of disease transmission. Therefore, legal regulations to limit supplemental feeding are often implemented ... -
Estimating and managing broad risk of chronic wasting disease spillover among cervid species
(Peer reviewed; Journal article, 2023-09-10)The management of infectious wildlife diseases often involves tackling pathogens that infect multiple host species. Chronic wasting disease (CWD) is a prion disease that can infect most cervid species. CWD was detected in ... -
European mushroom assemblages are darker in cold climates
(Peer reviewed; Journal article, 2019-10-10)Thermal melanism theory states that dark-colored ectotherm organisms are at an advantage at low temperature due to increased warming. This theory is generally supported for ectotherm animals, however, the function of colors ... -
Evaluating competition for forage plants between honey bees and wild bees in Denmark
(Peer reviewed; Journal article, 2021-04-28)A recurrent concern in nature conservation is the potential competition for forage plants between wild bees and managed honey bees. Specifically, that the highly sophisticated system of recruitment and large perennial ... -
Generic Ecological Impact Assessment of Alien Species (GEIAA): the third generation of assessments in Norway
(Journal article; Peer reviewed, 2019-06-25)The Generic Ecological Impact Assessment of Alien Species (GEIAA) is described. It comprises a set of criteria and an assessment procedure. The set of criteria consists of three criteria that quantify invasion potential, ... -
Genetic analysis indicates spatial-dependent patterns of sex-biased dispersal in Eurasian lynx in Finland
(Peer reviewed; Journal article, 2021-02-19)Conservation and management of large carnivores requires knowledge of female and male dispersal. Such information is crucial to evaluate the population’s status and thus management actions. This knowledge is challenging ... -
High tolerance of a high-arctic willow and graminoid to simulated ice encasement
(Journal article; Peer reviewed, 2018-12-17)Climate change-induced snow thaw and subsequent accumulation of ice on the ground is a potential, major threat to snow-dominated ecosystems. While impacts of ground-ice on arctic wildlife are well explored, the impacts on ... -
Highways associated with expansion of boreal scavengers into the alpine tundra of Fennoscandia
(Peer reviewed; Journal article, 2020-05-17)1. Habitat fragmentation may affect species distributions through, for example, altered resource availability and shifts in species interactions. Fragmentation by roads has had negative impacts on Fennoscandian alpine ... -
Incentivising open ecological data using blockchain technology
(Peer reviewed; Journal article, 2023-09-07)Research centred on understanding scientists’ attitudes towards open data in ecology and evolution point to an increased acceptance of and willingness to engage in open data practices1,2, but also identifies common threads ... -
Increased above‐ground resource allocation is a likely precursor for independent evolutionary origins of annuality in the Pooideae grass subfamily
(Peer reviewed; Journal article, 2020-05-18)Semelparous annual plants flower a single time during their 1‐yr life cycle, investing much of their energy into rapid reproduction. By contrast, iteroparous perennial plants flower multiple times over several years, and ... -
MetaComNet: A random forest- based framework for making spatial predictions of plant– pollinator interactions
(Peer reviewed; Journal article, 2021-11-12)1. Predicting plant–pollinator interaction networks over space and time will improve our understanding of how environmental change is likely to impact the functioning of ecosystems. Here we propose a framework for producing ... -
Moose in our neighborhood: Does perceived hunting risk have cascading effects on tree performance in vicinity of roads and houses?
(Peer reviewed; Journal article, 2022-04-03)Like large carnivores, hunters both kill and scare ungulates, and thus might indirectly affect plant performance through trophic cascades. In this study, we hypothesized that intensive hunting and enduring fear of humans ... -
Moth Outbreaks Reduce Decomposition in Subarctic Forest Soils
(Journal article; Peer reviewed, 2019)Tree mortality from insect infestations can significantly reduce carbon storage in forest soils. In subarctic birch forests (Betula pubescens), ecosystem C cycling is largely affected by recurrent outbreaks of defoliating ... -
Refrigeration or anti-theft? Food-caching behavior of Wolverines (Gulo gulo) in Scandinavia
(Peer reviewed; Journal article, 2020-04-15)Food-caching animals can gain nutritional advantages by buffering seasonality in food availability, especially during times of scarcity. The wolverine (Gulo gulo) is a facultative predator that occupies environments of low ... -
Restoration of transborder connectivity for Fennoscandian brown bears (Ursus arctos)
(Peer reviewed; Journal article, 2021-01-03)Knowledge about the connectivity among natural populations is essential to identify management units for effective conservation actions. Conservation-minded management has led to the recovery of large carnivore populations ... -
Right on track? Performance of satellite telemetry in terrestrial wildlife research
(Journal article; Peer reviewed, 2019-05-09)Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden ...
