Predation of Atlantic salmon across ontogenetic stages and impacts on populations
(Peer reviewed; Journal article, 2023)Managers and stakeholders increasingly ask whether predation is a driving force behind the poor status of many species, and whether predator control is likely to be a successful management action to intervene. We review ... -
Predation on livestock as an indicator of drastic prey decline? The indirect effects of an African swine fever epidemic on predator–prey relations in Poland
(Peer reviewed; Journal article, 2021)ABSTRACT The gray wolf (Canis lupus) is one of the most conflictual mammals in Europe. Wild boar (Sus scrofa) are an essential part of gray wolf diet in central Europe, but after the emergence of African swine fever (ASF) ... -
Predation or scavenging? Prey body condition influences decision-making in a facultative predator, the wolverine. Photo gallery
(Journal article; Peer reviewed, 2017)What determines whether a predator scavenges or kills its own prey? Using data on wolverines ( Gulo gulo ) in Scandinavia, we studied variation in diet and feeding strategies along a gradient of environmental productivity, ... -
Predation or scavenging? Prey body condition influencesdecision-making in a facultative predator, the wolverine
(Journal article; Peer reviewed, 2016)The interaction between predators and their prey is a key factor driving population dynamics and shaping wildlife communities. Most predators will scavenge in addition to killing their own prey, which alters predation ... -
Predation research with electronic tagging
(Peer reviewed; Journal article, 2022)Predation is a fundamental aspect of ecology that drives ecosystem structure and function. A better understanding of predation can be facilitated by using electronic tags that log or transmit positions of predator or prey ... -
Predation, parasitism, and drought counteract the benefits of patch-burn grazing for the reproductive success of grassland songbirds
(Journal article, 2022)Intensification of livestock production has reduced heterogeneity in vegetative structure in managed grasslands, which has been linked to widespread declines in grassland songbird populations throughout North America. ... -

Predators, stewards, or sportsmen – how do Norwegian hunters perceive their role in carnivore management?
(Peer reviewed; Journal article, 2013)Hunting is increasingly seen as a management strategy in regulating large carnivore populations and reducing conflicts with human interests. A central theme in the carnivore debate is the role of the hunter in simulating ... -
Predefinitive Plumage in the Golden Eagle (Aquila chrysaetos): A Signal of Aggression or Submission?

Predicting Foraging Habitat of European Shags - A Multi-Year and Multi-Colony Tracking Approach to Identify Important Areas for Marine Conservation
(Peer reviewed; Journal article, 2022)Human activity in the coastal zone is increasing worldwide, putting a number of seabird species under pressure. Norway is no exception to this development, and with > 35% of the NE Atlantic population of the currently ... -
Predicting kill sites of an apex predator from GPS data in different multi-prey systems
(Peer reviewed; Journal article, 2022)Kill rates are a central parameter to assess the impact of predation on prey species. An accurate estimation of kill rates requires a correct identification of kill sites, often achieved by field-checking GPS location ... -
Predicting the foraging patterns of wintering Auks using a sea surface temperature model for the Barents Sea
(Peer reviewed; Journal article, 2022)1. The conservation of seabirds is increasingly important for their role as indicator species of ocean ecosystems, which are predicted to experience increasing levels of exploitation this century. Safeguarding these ... -
Predicting the spatial expansion of an animal population with presence-only data
(Peer reviewed; Journal article, 2023)Predictive models can improve the efficiency of wildlife management by guiding actions at the local, landscape and regional scales. In recent decades, a vast range of modelling techniques have been developed to predict ... -
Prediction of biodiversity hotspots in the Anthropocene: The case of veteran oaks
(Journal article; Peer reviewed, 2017)Over the past centuries, humans have transformed large parts of the biosphere, and there is a growing need to understand and predict the distribution of biodiversity hotspots influenced by the presence of humans. Our basic ... -
Predictors of invertebrate biomass and rate of advancement of invertebrate phenology across eight sites in the North American Arctic
(Peer reviewed; Journal article, 2021)Average annual temperatures in the Arctic increased by 2–3 °C during the second half of the twentieth century. Because shorebirds initiate northward migration to Arctic nesting sites based on cues at distant wintering ... -
Presence of 6PPD-quinone in runoff water samples from Norway using a new LC–MS/MS method
(Peer reviewed; Journal article, 2023)The chemical 6PPD-quinone is highly toxic to some fish species of the Oncorhynchus and Salvelinus genera and is the oxidation product of the common car tire additive 6PPD. We present a new sample preparation method that ... -
Prevailing weather conditions and dietcomposition affect chick growth and survival in the black-legged kittiwake
(Journal article; Peer reviewed, 2018)To identify priorities for management of seabirds during the breeding season, it is important to understand the ecological mechanisms driving chick growth and survival. In this study, we examined the effects of diet and ... -
Prey predictability and preparation versus recovery breathing strategies in European shags Gulosus aristotelis (L.) diving in different habitats
(Peer reviewed; Journal article, 2023)A recent study on the diving behaviour of European shags (Gulosus aristotelis (L.)) foraging in kelp forests off rocky coasts of Norway suggests surface durations are related only to the duration of the preceding dive, and ... -
Prokelisia marginata (Van Duzee, 1897) (Hemiptera, Delphacidae) recorded for the first time in Northern Europe
(Journal article, 2019)The Nearctic planthopper Prokelisia marginata (Van Duzee, 1897) (Hemiptera, Delphacidae) is native to the eastern coast of North America on its foodplant, the cordgrass Spartina alterniflora (Poaceae). Both the hostplant ... -
Prospects for the future of pink salmon in three oceans: From the native Pacific to the novel Arctic and Atlantic
(Peer reviewed; Journal article, 2023)While populations of other migratory salmonids suffer in the Anthropocene, pink salmon (Oncorhynchus gorbusca Salmonidae) are thriving, and their distribution is expanding both within their natural range and in the Atlantic ...
