Performance of hunting statistics as spatiotemporal density indices of moose (Alces alces) in Norway
(Peer reviewed; Journal article, 2014)Wildlife managers are often asking for reliable information of population density across larger spatial scales. In this study, we examined the spatiotemporal relationships between moose density as estimated by cohort ... -
A natural antipredation experiment: predator control and reduced sea ice increases colony size in a long-lived duck
(Peer reviewed; Journal article, 2013)Anthropogenic impact on the environment and wildlife are multifaceted and far-reaching. On a smaller scale, controlling for predators has been increasing the yield from local natural prey resources. Globally, human-induced ... -
Using short-term monitoring data to achieve goals in a large-scale restoration
(Peer reviewed, 2013)To evaluate the outcome of restoration projects, an overall goal, reformulated to specific subgoals or targets, must be explicit and translated into scientifically measurable ecological attributes. Monitoring ecological ... -
AS WE SEE IT Reared fish, farmed escapees and wild fish stocks-a triangle of pathogen transmission of concern to Mediterranean aquaculture management
(Peer reviewed; Journal article, 2013)Although aquaculture in the Mediterranean is a relatively young industry, finfish dis eases have been reported to cause considerable problems and mortalities among the farmed stocks. In general, the farming activity and ... -
Development and testing of attachment methods for pop-up satellite archival transmitters in European eel
(Peer reviewed, 2013)Background: Four methods for attaching pop-up satellite transmitters to European eel were tested in the laboratory by recording long-term tag retention, growth and survival; short-term behavioral responses; and physical ... -
Body condition and feather molt of a migratory shorebird during the non-breeding season
(Peer reviewed; Journal article, 2018)Migratory shorebirds have some of the highest fat loads among birds, especially species which migrate long distances. The upland sandpiper Bartramia longicauda makes long distance migrations twice a year, but variation ... -
Global assessment of marine plastic exposure risk for oceanic birds
(Peer reviewed; Journal article, 2023)Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters ... -
An assessment of silvopastoral systems condition and their capacity to generate ecosystem services in the Colombian Amazon
(Peer reviewed; Journal article, 2023)Livestock production in the Colombian Amazonia is typically dual-purpose (meat and milk) based on silvopastoral systems. We aimed to assess how the ecological condition of these systems correspond to the ecosystem services ... -
Ice-dependent winter survival of juvenile Atlantic salmon
(Peer reviewed; Journal article, 2013)Changes in snow and ice conditions are some of the most distinctive impactsof global warming in cold temperate and Arctic regions, altering the environ-ment during a critical period for survival for most animals. Laboratories ... -
Sea duck predation in mussel farms: the best nets for excluding common eiders safely and efficiently
(Peer reviewed; Journal article, 2013)Shellfish aquaculture is a growing food-producing sector. The blue mussel Mytilus edulis is the primary farmed shellfish and is also a main prey for various species of sea ducks. With their large density of high-quality ... -
Using natural marks to estimate free-ranging dog Canis familiaris abundance in a MARK-RESIGHT framework in suburban Mumbai, India
(Peer reviewed; Journal article, 2012)Free-ranging dogs (Canis familiaris) are a major conservation issue in the tropics and adopt many ecological roles, alternatively functioning as predators, prey, or competitors of wildlife in diverse environments. Dogs are ... -
Whose Hydropower? From Conflictual Management into an Era of Reconciling Environmental Concerns; A Retake of Hydropower Governance towards Win-Win Solutions?
(Peer reviewed; Journal article, 2017)Hydropower has been core in the nation-building process of several countries. This includes Sweden in which it currently supplies around 50% of the electricity and particularly Norway where almost all electricity is generated ... -
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. ... -
Large carnivore conservation and traditional pastoralism: A case study on bear–reindeer predation mitigation measures
(Peer reviewed; Journal article, 2023)While wildlife and cultural preservation goals can be either complimentary orcounteractive, the goals of large carnivore conservation and traditional pastoralist lifestyles are often at odds. Livestock depredation can ... -
Evolution of complex symbiotic relationships in a morphologically derived family of lichen-forming fungi
(Peer reviewed; Journal article, 2015)We studied the evolutionary history of the Parmeliaceae (Lecanoromycetes, Ascomycota),one of the largest families of lichen-forming fungi with complex and variable morphologies,also including several lichenicolous fungi. ... -
The King of the Forest: Local Knowledge About European Brown Bears (Ursus arctos) and Implications for Their Conservation in Contemporary Western Macedonia
(Peer reviewed; Journal article, 2011)From a conservation point of view, Macedonia’s brown bear (Ursus arctos) population appears to be a key link in the distribution of one of Europe’s largest brown bear populations, the Dinaric-Pindos population. The lack ... -
Variation in albedo and other vegetation characteristics in non-forested northern ecosystems: the role of lichens and mosses
(Peer reviewed; Journal article, 2023)Vegetation has a profound impact on climate through complex interactions and feedback loops, where especially regulation of albedo, the ratio of reflected to incoming solar radiation, is important at high latitudes. How ... -
Female sociality and kin discrimination in brood parasitism: Unrelated females fight over egg laying
(Peer reviewed; Journal article, 2015)In conspecific brood parasitism, some females (“parasites”) lay eggs in nests of other females of the same species (“hosts”). This reproductive tactic is particularly common in waterfowl, in which studies suggest that ... -
Maternal Androgens Increase Sibling Aggression, Dominance, and Competitive Ability in the Siblicidal Black-Legged Kittiwake (Rissa tridactyla)
