Participatory monitoring drives biodiversity knowledge in global protected areas
Mandeville, Caitlin Marie; Nilsen, Erlend Birkeland; Herfindal, Ivar; Finstad, Anders Gravbrøt (Peer reviewed; Journal article, 2023)Protected areas are central in strategies to conserve biodiversity. Effective area-based conservation relies on biodiversity data, but the current biodiversity knowledge base is insufficient and limited by geographic and ... -
Quantifying risk of overharvest when implementation is uncertain
Eriksen, Lasse Frost; Moa, Pål Fossland; Nilsen, Erlend Birkeland (Journal article; Peer reviewed, 2017)1. Sustainable harvest management implies an ability to control harvest rates. This is challenging in systems that have limited control of resources and resource users, which is often the case in small game harvest management. ... -
Quantifying suitable late summer brood habitats for willow ptarmigan in Norway
Kvasnes, Mikkel Andreas Jørnsøn; Pedersen, Hans Christian; Nilsen, Erlend Birkeland (Journal article; Peer reviewed, 2018)Background: Habitat models provide information about which habitat management should target to avoid species extinctions or range contractions. The willow ptarmigan inhabits alpine- and arctic tundra habitats in the northern ... -
Quantifying the checks and balances of collaborative governance systems for adaptive carnivore management
Cusack, Jeremy J.; Nilsen, Erlend Birkeland; Israelsen, Markus Fjellstad; Andrén, Henrik; Grainger, Matthew; Linnell, John Durrus; Odden, John; Bunnefeld, Nils (Peer reviewed; Journal article, 2022)1. Recovering or threatened carnivore populations are often harvested to minimise their impact on human activities, such as livestock farming or game hunting. Increasingly, harvest quota decisions involve a set of scientific, ... -
Sharing data improves monitoring of trans-boundary populations: the case of wolverines in central Scandinavia
Gervasi, Vincenzo; Brøseth, Henrik; Gimenez, Olivier; Nilsen, Erlend Birkeland; Odden, John; Flagstad, Øystein; Linnell, John Durrus (Journal article; Peer reviewed, 2016)of wide-ranging species are likely to extend across multiple jurisdictions, including national and international borders. This requires that local institutions implement data sharing and a standardization of monitoring ... -
Survival and cause-specific mortality of harvested willow ptarmigan (Lagopus lagopus) in central Norway
Israelsen, Markus Fjellstad; Eriksen, Lasse Frost; Moa, Pål Fossland; Hagen, Bjørn-Roar; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2020)Survival is a key demographic component that often varies as a result of human activities such as recreational harvest. Detailed understanding of seasonal variation in mortality patterns and the role of various risk factors ... -
Survival and Migration of Rock Ptarmigan in Central Scandinavia
Nilsen, Erlend Birkeland; Moa, Pål Fossland; Brøseth, Henrik; Pedersen, Hans Christian; Hagen, Bjørn-Roar (Peer reviewed; Journal article, 2020)In a world undergoing massive declines in the distribution and abundance of many wildlife species, documenting basic ecological characteristics is often needed to be able to understand and potentially mitigate current and ... -
Temporal quota corrections based on timing of harvest in a small game species
Brøseth, Henrik; Nilsen, Erlend Birkeland; Pedersen, Hans-Christian (Peer reviewed; Journal article, 2012)Theoretical models have shown that the effect of removing a given proportion of the population can be profoundly different if the harvest takes place late in the season compared to early. We explore the effect of these ... -
The risks of learning: confounding detection anddemographic trend when using count-based indices forpopulation monitoring
Gervasi, Vincenzo; Brøseth, Henrik; Gimenez, Olivier; Nilsen, Erlend Birkeland; Linnell, John Durrus (Peer reviewed; Journal article, 2014)Theory recognizes that a treatment of the detection process is required to avoid producing biased estimates of population rate of change. Still, one of three monitoring programmes on animal or plant populations is focused ... -
The spatio-temporal distribution of wild and domestic ungulates modulates lynx kill rates in a multi-use landscape
Gervasi, Vincenzo; Nilsen, Erlend Birkeland; Odden, John; Bouyer, Yaëlle; Linnell, John Durrus (Journal article; Peer reviewed, 2014)Depredation on livestock and competition with hunters for game species are prominent among the conflicts that the return of large carnivores generates in multi-use landscapes. The relative magnitude of the conflict strongly ... -
Wildlife Camera Monitoring Revealed the Northern Goshawk as a Predator on Gyrfalcon Nestlings
Moen, Børje Cato; Kroglund, Rolf Terje; Østnes, Jan Eivind; Nilsen, Erlend Birkeland; Nygård, Torgeir (Peer reviewed; Journal article, 2023)Accipiter gentilis; Falco rusticolus; intraguild predation; nestling; nocturnal foraging; predation.
