Activity patterns of predator and prey : a simultaneous study of GPS-collared wolves and moose
(Journal article; Peer reviewed, 2011)We studied the simultaneous activity patterns of a breeding wolf, Canis lupus, pair and five adult moose, Alces alces, cows from April to November 2004 in a wolf territory in southeastern Norway. All study animals were GPS ... -
Behavioral responses of wolves to roads: scale-dependent ambivalence
(Journal article; Peer reviewed, 2014)Throughout their recent recovery in several industrialized countries, large carnivores have had to cope with a changed landscape dominated by human infrastructure. Population growth depends on the ability of individuals ... -
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 ... -
Evaluation of Medetomidine-Ketamine and atipamezole for reversible anesthesia of free-ranging gray wolves (Canis lupus)
(Journal article; Peer reviewed, 2013)Twenty-eight anesthetic events were carried out on 24 free-ranging Scandinavian gray wolves (Canis lupus) by darting from a helicopter with 5 mg medetomidine and 250 mg ketamine during winter in 2002 and 2003. Mean6SD ... -
Genetic signature of immigrants and their effect on genetic diversity in the recently established Scandinavian wolf population
(Peer reviewed; Journal article, 2021)Transboundary connectivity is a key component when conserving and managing animal species that require large areas to maintain viable population sizes. Wolves Canis lupus recolonized the Scandinavian Peninsula in the early ... -
Let’s stay together? Intrinsic and extrinsic factors involved in pair bond dissolution in a recolonizing wolf population
(Journal article; Peer reviewed, 2016)For socially monogamous species, breeder bond dissolution has important consequences for population dynamics, but the extent to which extrinsic or intrinsic population factors causes pair dissolution remain poorly understood, ... -
Mammal responses to predator scents across multiple study areas
(Peer reviewed; Journal article, 2022)Antipredator behaviors allow prey to mitigate the impacts of their predators. We investigated antipredator responses of two herbivore species, roe deer and European hare, and one mesopredator, red fox, toward predation ... -
Of wolves and bears: Seasonal drivers of interference and exploitation competition between apex predators
(Peer reviewed; Journal article, 2021)Competition between apex predators can alter the strength of top-down forcing, yet we know little about the behavioral mechanisms that drive competition in multipredator ecosystems. Interactions between predators can be ... -
Of wolves and bears: Seasonal drivers of interference and exploitation competition between apex predators
(Peer reviewed; Journal article, 2022)Competition between apex predators can alter the strength of top-down forcing, yet we know little about the behavioral mechanisms that drive competition in multipredator ecosystems. Interactions between predators can be ... -
Poaching-related disappearance rate of wolves in Sweden was positively related to population size and negatively to legal culling
(Peer reviewed; Journal article, 2020-03-14)Poaching is an important limiting factor for many large carnivore populations worldwide and the effect that legal culling has on poaching rate on wolf (Canis lupus) is debated. We used data linked to population monitoring ... -
Predator-dependent functional response in wolves: from food limitation to surplus killing
(Journal article; Peer reviewed, 2014)The functional response of a predator describes the change in per capita kill rate to changes in prey density. This response can be influenced by predator densities, giving a predator-dependent functional response. In ... -
Quiet islands in a world of fear: Wolves seek core zones of protected areas to escape human disturbance
(Peer reviewed; Journal article, 2022)The Anthropocene continuously escalates the challenges and threats faced by large carnivores in human-dominated landscapes. Given their unique conservation and management requirements, detailed insights into their behaviour ... -
Scavenging patterns of an inbred wolf population in a landscape with a pulse of human-provided carrion
(Peer reviewed; Journal article, 2023)Scavenging is an important part of food acquisition for many carnivore species that switch between scavenging and predation. In landscapes with anthropogenic impact, humans provide food that scavenging species can utilize. ... -
Spatial and temporal cohesion of parents and offspring in a social large carnivore
(Peer reviewed; Journal article, 2023)Social organization in animals is a fundamental factor driving population dynamics and individual spatial distribution. Affiliation among kin is common in social groups, but kinship is no safeguard against intraspecific ... -
A Standardized Method for Experimental Human Approach Trials on Wild Wolves
(Peer reviewed; Journal article, 2022)As wolves recolonize areas of Europe ranging from moderate to high anthropogenic impact, fear of wolves is a recurring source of conflict. Shared tools for evaluating wolf responses to humans, and comparing such responses ... -
Wolf habitat selection when sympatric or allopatric with brown bears in Scandinavia
(Peer reviewed; Journal article, 2020)Habitat selection of animals depends on factors such as food availability, landscape features, and intraand interspecific interactions. Individuals can show several behavioral responses to reduce competition for habitat, ... -
Wolf monitoring in Scandinavia: evaluating counts of packs and reproduction events
(Peer reviewed; Journal article, 2022)Large carnivores are elusive and use large areas, which causes monitoring to be challenging and costly. Moreover, management to reduce conflicts and simultaneously ensure long‐term population viability require precise ... -
Wolf Responses to Experimental Human Approaches Using High-Resolution Positioning Data
(Peer reviewed; Journal article, 2022)Humans pose a major mortality risk to wolves. Hence, similar to how prey respond to predators, wolves can be expected to show anti-predator responses to humans. When exposed to a threat, animals may show a fight, flight, ... -
Wolves, people, and brown bears influence the expansion of the recolonizing wolf population in Scandinavia
(Journal article; Peer reviewed, 2015)Interspecific competition can influence the distribution and abundance of species and the structure of ecological communities and entire ecosystems. Interactions between apex predators can have cascading effects through ...
