Hvordan potensielle konkurrenter og predatorer påvirker fjellrevens (Vulpes lagopus) atferd ved to ulike matplasser : eksperimentelle kadavre og eksklusive fôrautomater
Baksaas, Emilie Lian; Synnøve, Myklebust (Master thesis, 2021)Konkurranse er en velkjent økologisk mekanisme som oppstår når flere individer eller arter utnytter en begrenset ressurs. I den alpine tundraen er ressurstilgangen særlig lav, og den truede fjellreven (Vulpes lagopus) er ... -
Integrating data from different survey types for population monitoring of an endangered species: the case of the Eld’s deer
Bowler, Diana Elizabeth; Nilsen, Erlend Birkeland; Bischof, Richard; O'Hara, Robert B.; Yu, Thin Thin; Oo, Tun; Aung, Myint; Linnell, John Durrus (Journal article; Peer reviewed, 2019)Despite its value for conservation decision-making, we lack information on population abundances for most species. Because establishing large-scale monitoring schemes is rarely feasible, statistical methods that combine ... -
Kan deltakelse i borgerforskningsprosjekter øke elevers interesse for naturfag på skolen?
Stigsrud, Ole-Andreas (Master thesis, 2021)Kattesporet er et forskningsprosjekt som bruker barnefamilier som borgerforskere, for å studere huskatters atferd utendørs. Barnefamiliene dokumenterte kattens atferd og bevegelsesmønster med GPS og viltkamera over en ... -
Landscape-scale determinants and dynamics of large carnivore density
Moqanaki, Ehsan Mohammadi (PhD Thesis;2023:36, Doctoral thesis, 2023)1. Wildlife populations live in increasingly human-altered landscapes. Either because of their intrinsic values or due to instrumental values to humans, wildlife populations are monitored to inform about their current ... -
Large carnivore responses to human activity and infrastructure at multiple scales in Scandinavia
Thorsen, Neri Horntvedt (PhD Thesis;2021:94, Doctoral thesis, 2021) -
Leveraging non-invasive monitoring of carnivores using hierarchical models
Tourani, Mahdieh (PhD thesis;2020:59, Doctoral thesis, 2020)The development of non-invasive approaches for monitoring wildlife populations made it feasible to obtain ecological parameters across landscapes and populations, rather than a few locations or individuals. The two most ... -
Linking high frequency GPS data with multiscale habitat selection : a study of an adaptable carnivore in a fragmented landscape
Toverud, Finn Sigurd Klaveness (Master thesis, 2019)BACKGROUND: The expansion of human activity has had a significant impact on wildlife. Some of these effects are challenging to observe, especially in the case of illusive and nocturnal carnivores. GPS technology offers ... -
Linking noninvasive genetic sampling and traditional monitoring to aid management of a trans-border carnivore population
Bischof, Richard; Swenson, Jon (Journal article; Peer reviewed, 2012) -
Noninvasive genetic sampling reveals intrasex territoriality in wolverines
Bischof, Richard; Gregersen, Espen Rise; Brøseth, Henrik; Ellegren, Hans; Flagstad, Øystein (Journal article; Peer reviewed, 2016) -
Personality differences among domestic cats (Felis catus) in Norway and how they affect home range size
Kisen, Astrid (Master thesis, 2021)Research on animal personalities has greatly increased in the last few decades, revealing it as an influential contribution to survival and space utilisation. Domestic cats pose a risk to wildlife through disease transmission ... -
Population closure and the bias-precision trade-off in spatial capture–recapture
Dupont, Pierre; Milleret, Cyril Pierre; Gimenez, Olivier; Bischof, Richard (Journal article; Peer reviewed, 2019) -
Regulated hunting re-shapes the life history of brown bears
Bischof, Richard; Bonenfant, Christophe; Rivrud, Inger Maren; Zedrosser, Andreas; Friebe, Andrea; Coulson, Tim; Mysterud, Atle; Swenson, Jon (Journal article; Peer reviewed, 2018)Management of large carnivores is among the most controversial topics in natural resource administration. Regulated hunting is a centrepiece of many carnivore management programmes and, although a number of hunting effects ... -
RovQuant : estimating density, abundance and population dynamics of bears, wolverines and wolves in Scandinavia
Bischof, Richard; Milleret, Cyril; Dupont, Pierre; Chipperfield, Joseph; Brøseth, Henrik; Kindberg, Jonas (MINA fagrapport;63, Report, 2019)Background Reliable estimates of population status are a pre-requisite for informed wildlife management. However, abundance estimates can be challenging to obtain, especially for species that are highly mobile, rare and ... -
Saving large carnivores, but losing the apex predator?
Ordiz Fernandez, Andres Avelino; Bischof, Richard; Swenson, Jon (Journal article; Peer reviewed, 2013)Large terrestrial carnivores, e.g. wolves or bears, often play a key ecological role from their position at the apex of trophic systems. Changes to their populations reverberate through ecological communities; consequently ... -
Silver spoon effects are constrained under extreme adult environmental conditions
Pigeon, Gabriel; Loe, Leif Egil; Bischof, Richard; Bonenfant, Christophe; Forchhammer, Mads C.; Irvine, R. Justin; Ropstad, Erik; Stien, Audun; Veiberg, Vebjørn; Albon, Steve (Peer reviewed; Journal article, 2019)Early-life environmental conditions may generate cohort differences in individual fitness, subsequently affecting population growth rates. Three, nonmutually exclusive hypotheses predict the nature of these fitness ... -
Smartphone app reveals that lynx avoid human recreationists on local scale, but not home range scale
Thorsen, Neri Horntvedt; Bischof, Richard; Mattisson, Jenny; Hofmeester, Tim R.; Linnell, John Durrus; Odden, John (Peer reviewed; Journal article, 2022)The global incrOutdoor recreation is increasing and afects habitat use and selection by wildlife. These efects are challenging to study, especially for elusive species with large spatial requirements, as it is hard to ... -
