Rådyrets (Capreolus capreolus) økologi i urbane områder, Moss og Råde kommune, Viken fylkeskommune
Hagen, Emely Maria Hegna (Master thesis, 2023)Økende befolkning og urbanisering fører til habitat tap-, og fragmentering. Dette kan ramme hjortevilt som blir tvunget til å finne nye hjemmeområder. Økt mattilgang og lav predasjonsrate gjør urbane områder attraktive. ... -
Scent-sniffing dogs can discriminate between native Eurasian and invasive North American beavers
Rosell, Frank; Cross, Hannah; Johnsen, Christin Beate; Sundell, Janne; Zedrosser, Andreas (Peer reviewed; Journal article, 2019)The invasion of a species can cause population reduction or extinction of a similar native species due to replacement competition. There is a potential risk that the native Eurasian beaver (Castor fiber) may eventually be ... -
Seasonal and annual variation in the diet of brown bears Ursus arctos in the boreal forest of southcentral Sweden
Stenset, Nina Emilie; Lutnæs, Paul Antoni Nilsen; Bjarnadóttir, Valgerður; Dahle, Bjørn Steinar; Fossum, Kristin Høivik; Jigsved, Patrick; Johansen, Thomas; Neumann, Wiebke; Opseth, Ole; Rønning, Oddmund; Steyaert, Sam; Zedrosser, Andreas; Brunberg, Sven; Swenson, Jon (Journal article; Peer reviewed, 2016)Understanding a species' feeding ecology is essential for successful management and conservation, because food abundance can influence body mass, survival, reproductive success, movements, and habitat use. We describe ... -
Seasonal and diel movement patterns of brown bears in a population in southeastern Europe
Bogdanović, Neda; Hertel, Anne G.; Zedrosser, Andreas; Paunović, Milan; Plećaš, Milan; Ćirović, Duško (Peer reviewed; Journal article, 2021)Most animals concentrate their movement into certain hours of the day depending on drivers such as photoperiod, ambient temperature, inter- or intraspecific competition, and predation risk. The main activity periods of ... -
Sex discrimination via anal gland secretion in a territorial monogamous mammal
Cross, Hannah; Zedrosser, Andreas; Nevin, Owen; Rosell, Frank (Journal article; Peer reviewed, 2014-07-12)Monogamy in mammals is relatively unusual, only occurring in 3-5% and to an even lesser degree in rodents. Monogamy exists in two forms, facultative which evolved due to female dispersion and obligate when male care is ... -
Social environment shapes female settlement decisions in a solitary carnivore
Hansen, Jennifer Eve; Hertel, Anne Gabriela; Frank, Shane C.; Kindberg, Jonas; Zedrosser, Andreas (Peer reviewed; Journal article, 2021)How and where a female selects an area to settle and breed is of central importance in dispersal and population ecology as it governs range expansion and gene flow. Social structure and organization have been shown to ... -
Socio-ecological features other than sex affect habitat selection in the socially obligate monogamous Eurasian beaver
Steyaert, Sam; Zedrosser, Andreas; Rosell, Frank (Journal article; Peer reviewed, 2015-08-11)Habitat selection is a context-dependent mechanism, in which both the internal state as well as external factors affect the behavior and decisions of an individual. This is well known for polygamous mammals, which are ... -
Sociodemographic factors modulate the spatial response of brown bears to vacancies created by hunting
Frank, Shane C.; Leclerc, Martin; Pelletier, Fanie; Rosell, Frank; Swenson, Jon; Bischof, Richard; Kindberg, Jonas; Eiken, Hans Geir; Hagen, Snorre; Zedrosser, Andreas (Journal article; Peer reviewed, 2017)1. There is a growing recognition of the importance of indirect effects from hunting on wildlife populations, e.g. social and behavioural changes due to harvest, which occur after the initial offtake. Nonetheless, little ... -
Temporal effects of hunting on foraging behavior of an apex predator: Do bears forego foraging when risk is high?
Hertel, Anne Gabriela; Zedrosser, Andreas; Mysterud, Atle; Støen, Ole-Gunnar; Steyaert, Sam; Swenson, Jon (Journal article; Peer reviewed, 2016)Avoiding predators most often entails a food cost. For the Scandinavian brown bear (Ursus arctos), the hunting season coincides with the period of hyperphagia. Hunting mortality risk is not uniformly distributed throughout ... -
The relative importance of direct and indirect effects of hunting mortality on the population dynamics of brown bears
Gosselin, Jacinthe; Zedrosser, Andreas; Swenson, Jon; Pelletier, Fanie (Journal article; Peer reviewed, 2014)There is increasing evidence of indirect effects of hunting on populations. In species with sexually selected infanticide (SSI), hunting may decrease juvenile survival by increasing male turnover. We aimed to evaluate the ... -
Toxic elements in arctic and sub-arctic brown bears: Blood concentrations of As, Cd, Hg and Pb in relation to diet, age, and human footprint
Fuchs, Boris; Joly, Kyle; Hilderbrand, Grant V.; Evans, Alina; Rodushkin, Ilia; Mangipane, Lindsey S.; Mangipane, Buck A.; Gustine, David D.; Zedrosser, Andreas; Brown, Ludovick; Arnemo, Jon Martin (Peer reviewed; Journal article, 2023)Contamination with arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb) is a global concern impairing resilience of organisms and ecosystems. Proximity to emission sources increases exposure risk but remoteness does not ... -
Use of marking trees by roe deer
Myhre, Jo-Tellef (Master thesis, 2023)Scent marking and chemical communication play an important role in the behavioural ecology of many species. Scent marking is a form of olfactory communication used by an animal that deposits its odor in specific places to ... -
Viltets bruk av viltpassasjer for kryssing av E18 i Larvik kommune med hovedfokus på hjortedyr
Steen, Sondre Tobias; Omlid, Hilde Mari (Master thesis, 2022)Fragmentering av viltets leveområder er et stadig økende problem. Det er utført få storskala undersøkelser i Norge om bruk av viltpassasjer for kryssing av veier, og kartlegging er et gunstig tiltak for å få kunnskap om ... -
Walking on the Dark Side: Anthropogenic Factors Limit Suitable Habitat for Gray Wolf (Canis lupus) in a Large Natural Area Covering Belarus and Ukraine
Kudrenko, Svitlana; Fenchuk, Viktar; Vollering, Julien Martin Marie; Zedrosser, Andreas; Selva, Nuria; Ostapowicz, Katarzyna Anna; Beasley, James C.; Heurich, Marco Dietmar (Peer reviewed; Journal article, 2023)Due to successful conservation initiatives and legislations, the grey wolf (Canis lupus) is re-colonising its historic range in Europe. However, wolves have never been extirpated across large areas in Eastern Europe but ... -
