An evaluation of the efficiency of survey methods to monitor large mammals in Cusuco National Park, Honduras
Storm, Nina Andrea (Master thesis, 2017)Field sign surveys and camera trap surveys are frequently used in the tropics as the preferred survey technique to monitor large terrestrial mammal communities. However, these methods vary in the efficiency of detecting ... -
Behavioral responses to camera traps : a study on two large carnivores in Norway
Beddari, Benedicte Lissner (Master thesis, 2019)In ecology, camera trapping is commonly used as a non-invasive technique to collect ecological observation data and to monitor populations. The technique is used to address a variety of research questions worldwide. Despite ... -
Behavioral responses to olfactory attractants at camera traps : a study of three carnivores in a boreal ecosystem
Brøste, Ellen Nordrum (Master thesis, 2018)Camera trapping is an efficient and minimally invasive method for studying wildlife ecology and behavior. In camera trap studies, it is important to consider the detection probability to get reliable estimates of e.g. ... -
Behavioural responses of captive red fox (Vulpes vulpes) to telemetry collars
Bruholt, Sigrid (Master thesis, 2018)Telemetry is one of the most important tools of wildlife research. It provides information about dispersal, home range, survival, movement and many other ecological and biological aspects. Although many animals are fitted ... -
Determinants of domestic cat ocurrence in forests in southeastern Norway
Nyheim, Øyvind Skarsgard (Master thesis, 2022)Domestic cats can pose a significant threat to local wildlife in urban and rural areas because of their high densities and proficiency as predators. However, few attempts have been made to quantify the impact of domestic ... -
Determinants of scent-marking behavior by Asiatic cheetahs (Acinonyx jubatus venaticus) at camera traps in Iran
Enger, Kristian Bones (Master thesis, 2021)Scent marking is a common behaviour in large carnivores and serves a multiple of ecological purposes. It functions as a method of communication, either to warn off intruders, attract mates or to mark territory. In surveys ... -
Disentangling the drivers of European badger (Meles meles) activity at multiple temporal scales
Bartra Cabré, Laura (Master thesis, 2020)Animals shape their activity in response to several processes that take place at different timescales. It stands to reason that the assessment of activity at multiple temporal scales will enhance the understanding of its ... -
Effects of resource availability on Arctic fox (Vulpes lagopus) offspring sex ratios
Flølo, Linn Marie (Master thesis, 2022)The sex ratio of animals at birth has long been a topic of genetic, evolutionary, and biological interest. In polygynous species, mothers in good condition are typically expected to produce more males, while mothers in ... -
En test av olfaktoriske tiltrekningsstoffers effekt på oppdagelsessannsynlighet gjennom bruk av viltkamera
Bakken, Sigurd (Master thesis, 2018)Over store deler av verden har man opplevd en dramatisk tilbakegang av de store toppredatorene. Minsket predasjon fra toppredatorer kan lede til minsket intraguild konkurranse og en økning i tetthet av mesopredatorer. Denne ... -
Estimating and analysing the occupancy of the introduced shrew Crocidura russula in Norway
Talleraas, Simen Moflag (Master thesis, 2021)The Greater white-toothed shrew (Crocidura russula) is a shrew that was discovered in Norway in 2017. The species is of concern because it is invasive and has a history of environmental impact. It is native around the ... -
Estimating densities of red foxes using non-invasive genetic sampling and spatial capture-recapture modeling
Lindsø, Lars Kristian (Master thesis, 2020)Spatial capture-recapture modelling (SCR) is a powerful tool for estimating densities, population size and space use of elusive animals. However, SCR modeling has not been widely applied to ecologically important mesopredators ... -
Fine-scale assessment of responses to roads by red foxes
Kuskemoen, Emma (Master thesis, 2020)Anthropogenic alterations are prevalent in most landscapes today, and roads have a distinct impact on the ecosystems they intersect and on the wildlife populations inhabiting them. Understanding and quantifying wildlife ... -
Home ranges of domestic cats (Felis catus) in south-eastern Norway
Bachmann, Bettina (Master thesis, 2020)Small GPS units were used to track pet cats in south-eastern Norway from august 2019 to November 2019, in order to obtain home range size estimates. In total, 111 (51 females and 60 males) cats were tracked using their ... -
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 ... -
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 ... -
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 ... -
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 ... -
Space use and preferred places among domestic cats in Ås, south-eastern Norway
Prestmoen, Lillian (Master thesis, 2022)Cats are popular pets and are usually allowed to roam free when owners let them out of the house. The home range size of cats has been well studied, but we know very little about how cats use the space within their home ... -
Species-specific effect of forest cover on the occupancy of tropical forest mammals of Southeast Asia
Joshi, Pradeep Raj (Master thesis, 2022)Tropical forests harbour more than half of the world’s biodiversity and 63% of the world’s terrestrial mammals. Today this biodiversity is under threat due to habitat loss and degradation by human activities. This makes ... -
