Barn og natur : en spørreundersøkelse om kunnskap og holdning til naturen blant norske femteklassinger
Lillebo, Hans Martin; Gundersen, Hege; Nilsen, Erlend Birkeland (Oppdragsrapport, Research report, 2008)Norsk: Det er en tendens til at nærhet til naturen gir positive utslag for barna fra landet i forhold til naturopplevelse (litt høyere score enn barna fra byen). Den samme tendensen er ikke gjeldende i forhold til bruken ... -
Coexistence of large mammals and humans is possible in Europe’s anthropogenic landscapes
Cretois, Benjamin; Linnell, John Durrus; Van Moorter, Bram; Kaczensky, Petra; Nilsen, Erlend Birkeland; Parada, Jorge Sicacha; Rød, Jan Ketil (Peer reviewed; Journal article, 2021)A critical question in the conservation of large mammals in the Anthropocene is to know the extent to which they can tolerate human disturbance. Surprisingly, little quantitative data is available about large-scale effects ... -
Contrasting responses of two passerine bird species to moose browsing
Mathisen, Karen Marie; Pedersen, Simen; Nilsen, Erlend Birkeland; Skarpe, Christina (Journal article; Peer reviewed, 2012)Large herbivores may modify the ecosystem in a way that affects habitat quality and resource availability for other fauna. The increase in wild ungulate abundance in many areas may therefore lead to ecosystem changes, affecting ... -
Demographic side effects of selective hunting in ungulates and carnivores
Milner, Jos M.; Nilsen, Erlend Birkeland; Andreassen, Harry Peter (Peer reviewed; Journal article, 2007)Selective harvesting regimes are often implemented because age and sex classes contribute differently to population dynamics and hunters show preferences associated with body size and trophy value. We reviewed the ... -
Dødspeilesenderprosjektet 2006 : en undersøkelse av tapsomfang og tapsårsaker hos lam på utmarksbeite i Flekkefjord, Lund østre og Falkemannen beitelag
Sørby, Julie Gaukerud; Clemensen, Stein Gunnar; Nilsen, Erlend Birkeland (Oppdragsrapport, Research report, 2008-08-08)Norsk: I beitesesongen 2006 ble det gjennomført et dødspeilesenderprosjekt på grensen mellom Rogaland og Vest-Agder. Kommunene som var involvert i prosjektet var Lund (Rogaland), Flekkefjord (Vest-Agder) og Sirdal ... -
Harvesting a red-listed species: determinant factors for willow ptarmigan harvest rates, bag sizes, and hunting efforts in Norway
Breisjøberget, Jo Inge; Odden, Morten; Storaas, Torstein; Nilsen, Erlend Birkeland; Kvasnes, Mikkel Andreas Jørnsøn (Peer reviewed; Journal article, 2018) -
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 ... -
Human impact on the spatiotemporal dynamics of red fox in the boreal forests of SE Norway

Hunting moose or keeping sheep? - Producing meat in areas with carnivores
Milner, Jos M.; Nilsen, Erlend Birkeland; Wabakken, Petter; Storaas, Torstein (Journal article; Peer reviewed, 2005)Moose hunting is of considerable economic and social importance in much of Scandinavia. In some parts, such as south-east Norway, it is economically more important than sheep farming. We examine trends in moose harvesting ... -
Large-scale climate variability and rodent abundance modulates recruitment rates in Willow Ptarmigan (Lagopus lagopus)
Kvasnes, Mikkel Andreas Jørnsøn; Pedersen, Hans Christian; Storaas, Torstein; Nilsen, Erlend Birkeland (Journal article; Peer reviewed, 2014)Recruitment of juveniles is important for the size of the next year’s breeding population in many bird species. Climate variability and predation may affect recruitment rates, and when these factors are spatially correlated, ... -
Quantifying risk of overharvest when implementation is uncertain
Eriksen, Lasse Frost; Moa, Pål Fossland; Nilsen, Erlend Birkeland (Peer reviewed; Journal article, 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. ... -
