A Double-Blinded, Randomized Comparison of Medetomidine-Tiletamine-Zolazepamand Dexmedetomidine-Tiletamine-Zolazepam Anesthesia in Free-Ranging Brown Bears (Ursus Arctos)
(Journal article; Peer reviewed, 2017)We compared anesthetic features, blood parameters, and physiological responses to either medetomidine-tiletamine-zolazepam or dexmedetomidine-tiletamine-zolazepam using a double-blinded, randomized experimental design ... -
Agent-based models predict patterns and identify constraints of large carnivore recolonizations, a case study of wolves in Scandinavia
(Peer reviewed; Journal article, 2020)Large carnivores are recolonizing areas of their historical range in Europe. This process has strong implications for conservation and management related to human-wildlife conflicts. Analyses and modelling of the observed ... -
Arterial oxygenation and acid–base status before and during oxygen supplementation in captive European bison (Bison bonasus) immobilized with etorphine-acepromazine-xylazine
(Peer reviewed; Journal article, 2023)Chemical immobilization of captive European bison (Bison bonasus) is often required for veterinary care, transportation, or husbandry practices playing an important role in conservation breeding and reintroduction of the ... -
Assessing Evolutionary Significant Units (ESU) of the Endangered Freshwater Pearl Mussel (Margaritifera margaritifera) in Southeast Norway on the Basis of Genetic Analysis
(Peer reviewed; Journal article, 2020)A total of 312 specimens of freshwater pearl mussel (Margaritifera margaritifera) were sampled from 11 populations, located in four different river systems in Southeast Norway, and analyzed for 11 simple sequence repeat ... -
Assessment and Spatial Planning for Peatland Conservation and Restoration: Europe’s Trans-Border Neman River Basin as a Case Study
(Peer reviewed; Journal article, 2021)Peatlands are the “kidneys” of river basins. However, intensification of agriculture and forestry in Europe has resulted in the degradation of peatlands and their biodiversity (i.e., species, habitats and processes in ... -
Beaver foraging patterns in a human-dominated landscape: Effects on woody vegetation and mammals
(Peer reviewed; Journal article, 2023)Beavers can change habitat composition by cutting down trees, digging, and damming activities, thereby affecting species richness and abundance. Although there is large body of literature regarding the effects of beaver ... -
Behavioral modifications by a large-northern herbivore to mitigate warming conditions
(Peer reviewed; Journal article, 2020)Background: Temperatures in arctic-boreal regions are increasing rapidly and pose significant challenges to moose (Alces alces), a heat-sensitive large-bodied mammal. Moose act as ecosystem engineers, by regulating forest ... -
A brain and a head for a different habitat: Size variation in four morphs of Arctic charr (Salvelinus alpinus (L.)) in a deep oligotrophic lake
(Peer reviewed; Journal article, 2020)Adaptive radiation is the diversification of species to different ecological niches and has repeatedly occurred in different salmonid fish of postglacial lakes. In Lake Tinnsjøen, one of the largest and deepest lakes in ... -
Camera trapping reveals habitat overlap between snow leopards and common leopards in Gaurishankar Conservation Area, Nepal
(Peer reviewed, 2023)We provide camera trap records of the presence of two large predators: the snow leopard Panthera uncia and common leopard Panthera pardus from the same habitats in Lapchi Valley of Gaurishankar Conservation Area. Camera ... -
Chewing lice Trichodectes pinguis pinguis in Scandinavian brown bears ( Ursus arctos )
(Journal article; Peer reviewed, 2016)In April 2014 and 2015, we noted localized alopecia (neck, forelimbs, and chest) and hyperpigmentation on two adult brown bears (Ursus arctos) captured in central-south Sweden for ecological studies under the Scandinavian ... -
A common statement on anthropogenic hybridization of the European wildcat (Felis silvestris)
(Peer reviewed; Journal article, 2023)Preserving natural genetic diversity and ecological function of wild species is a central goal in conservation biology. As such, anthropogenic hybridization is considered a threat to wild populations, as it can lead to ... -
Determinants of nonindustrial private forest owners' willingness to harvest timber in Norway
(Peer reviewed; Journal article, 2020)In Norway, 84% of the productive forest is privately owned, and these forests dominate the supply of timber to industries. However, during last 80 years, annual forest growth has seen a substantial upsurge while annual ... -
Economic Gain vs. Ecological Pain—Environmental Sustainability in Economies Based on Renewable Biological Resources
(Peer reviewed; Journal article, 2020)There are two main international strategies concerning how to ensure a sustainable environment: one is to develop a globally bio-based economy, or bioeconomy, to meet the increased demand of goods and products to maintain ... -
Effects of cattle grazing on young spruce trees in boreal production forest
(Peer reviewed; Journal article, 2024)The compatibility of forest livestock grazing with timber production is disputed, as livestock can damage young trees through browsing and trampling. At the same time, livestock grazing might reduce the growth of competing ... -
Effects of heterogeneity on the ecological diversity and redundancy of forest fauna
(Peer reviewed; Journal article, 2023)Heterogeneity in forests might promote biodiversity not only through an increase in niche volume but also through other processes, such as an increase in resources and their spatial distribution. However, negative relationships ... -
Effects of large carnivores, hunter harvest, and weather on the mortality of moose calves in a partially migratory population
(Peer reviewed; Journal article, 2023)Survival of juvenile ungulates represents an important demographic parameter that influences population dynamics within ecosystems. In many ecological systems, the mortality of juvenile ungulates is influenced by various ... -
Examining leopard attacks: spatio-temporal clustering of human injuries and deaths in Western Himalayas, India
(Peer reviewed; Journal article, 2023)Shared spaces in Africa and Asia accommodate both humans and big cats. This engenders rare but distinctive cases of human fatalities by lions, tigers, and leopards. Among big cats, leopards have the widest range and occur ... -
First photographic evidence of the Binturong Arctictis binturong (Raffles, 1821) from Nepal
(Peer reviewed; Journal article, 2022)This is the first photographic confirmation of the occurrence of Binturong Arctictis binturong from Nepal. Although based on anecdotal reports, the species was believed to occur in the eastern Himalaya of Nepal but its ... -
Genetic diversity, gene flow, and landscape resistance in a pond-breeding amphibian in agricultural and natural forested landscapes in Norway
(Peer reviewed; Journal article, 2023)Genetic diversity is a key part of biodiversity, threatened by human activities that lead to loss of gene flow and reduction of effective population sizes. Gene flow is a result of both landscape connectivity and demographic ... -
