Climatic forcing and individual heterogeneity in a resident mountain bird : legacy data reveal effects on reproductive strategies
Eriksen, Lasse Frost; Ringsby, Thor Harald; Pedersen, Hans Christian; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2023)Optimization of clutch size and timing of reproduction have substantial effects on lifetime reproductive success in vertebrates, and both individual quality and environmental variation may impact life history strategies. ... -
Drivers and consequences of partial migration in an alpine bird species
Arnekleiv, Øyvind Lorvik; Eldegard, Katrine; Moa, Pål Fossland; Eriksen, Lasse Frost; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2022)1. Partial migration, where a portion of the population migrates between win-ter and summer (breeding) areas and the rest remain year- round resident, is a common phenomenon across several taxonomic groups. Several hypotheses ... -
Fecal DNA metabarcoding reveals seasonal and annual variation in willow ptarmigan diet
Ingvaldsen, Elise W.; Østnes, Jan E.; Kleven, Oddmund; Davey, Marie; Fossøy, Frode; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2024)Understanding spatio-temporal variation in the diet of alpineherbivores is important to predict how a changing climate willaffect these species in the future. We examined the spatio-temporal variation in willow ptarmigan ... -
Harvest Regulations and Implementation Uncertainty in Small Game Harvest Management
Moa, Pål Fossland; Eriksen, Lasse Frost; Nilsen, Erlend Birkeland (Journal article; Peer reviewed, 2017)A main challenge in harvest management is to set policies that maximize the probability that management goals are met. While the management cycle includes multiple sources of uncertainty, only some of these has received ... -
Heuristics for the sustainable harvest of wildlife in stochastic social-ecological systems
Law, Elizabeth; Linnell, John Durrus; Van Moorter, Bram; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2021)Sustainable wildlife harvest is challenging due to the complexity of uncertain social-ecological systems, and diverse stakeholder perspectives of sustainability. In these systems, semi-complex stochastic simulation models ... -
Impacts of predator-mediated interactions along a climatic gradient on the population dynamics of an alpine bird
Bowler, Diana Elizabeth; Kvasnes, Mikkel Andreas Jørnsøn; Pedersen, Hans Christian; Sandercock, Brett; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2020)According to classic theory, species’ population dynamics and distributions are less influenced by species interactions under harsh climatic conditions compared to under more benign climatic conditions. In alpine and boreal ... -
Interspecific competition impacts the occupancy and range limits of two ptarmigan species along the elevation gradient in Norway
Mandeville, Caitlin P.; Finstad, Anders G.; Kålås, John A.; Stokke, Bård G.; Øien, Ingar J.; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 2024)Many mountain species are expected to respond to climate change through upslope shifts of their range limits, but competition may restrict or alter this response. Under traditional range-limit theory, it is expected that ... -
