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 ... -
Anthropogenic effects on spatiotemporal activity patterns and interactions in a predator-prey assemblage
Thorsen, Neri Horntvedt (Master thesis, 2016-08-31)Evidence is accumulating that human presence and anthropogenic features in the environment impact the spatiotemporal activity patterns of both predators and prey. This is liable to affect predator-prey interactions, one ... -
Assessing snow leopard (Uncia uncia) by sign surveys and camera trapping in Northern Pakistan

Behavioral buffering of extreme weather events in a high-Arctic herbivore
Loe, Leif Egil; Hansen, Brage Bremset; Stien, Audun; Albon, Steve D.; Bischof, Richard; Carlsson, Anja M.; Irvine, Justin; Meland, Morten; Rivrud, Inger Maren; Ropstad, Erik; Veiberg, Vebjørn; Mysterud, Atle (Journal article; Peer reviewed, 2016)As global warming advances, there is a growing concern about the impact of extreme weather events on ecosystems. In the Arctic, more frequent unseasonal warm spells and rain-on- snow events in winter cause changes in ... -
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 ... -
Being the underdog: An elusive small carnivore uses space with prey and time without enemies
Bischof, Richard; Ali, H; Kabir, M.; Hameed, Shaista; Nawaz, Muhammad Ali (Journal article; Peer reviewed, 2014) -
Berry production drives bottom – up effects on body mass and reproductive success in an omnivore
Hertel, Anne Gabriela; Bischof, Richard; Langval, Ola; Mysterud, Atle; Kindberg, Jonas; Swenson, Jon; Zedrosser, Andreas (Journal article; Peer reviewed, 2017)Obligate herbivores dominate studies of the eff ects of climate change on mammals, however there is limited empirical evidence for how changes in the abundance or quality of plant food aff ect mammalian omnivores. Omnivores ... -
Border Security Fencing and Wildlife: The Endof the Transboundary Paradigm in Eurasia?
Linnell, John Durrus; Trouwborst, Arie; Boitani, Luigi; Kaczensky, Petra; Huber, Djuro; Reljic, Slaven; Kusak, Josip; Majic, Aleksandra; Skrbinsek, Tomaz; Potočnik, Hubert; Hayward, Matt W.; Milner-Gulland, E.J.; Buuveibaatar, Bayarbaatar; Olson, Kirk A.; Badamjav, Lkhagvasuren; Bischof, Richard; Zuther, Steffen; Breitenmoser, Urs (Journal article; Peer reviewed, 2016)The ongoing refugee crisis in Europe has seen many countries rush to construct border security fencing to divert or control the flow of people. This follows a trend of border fence construction across Eurasia during the ... -
Caught in the mesh: roads and their network-scale impediment to animal movement
Bischof, Richard; Steyaert, Sam; Kindberg, Jonas (Journal article; Peer reviewed, 2017)Roads have a pervasive multi-faceted influence on ecosystems, including pronounced impacts on wildlife movements. In recognition of the scale-transcending impacts of transportation infrastructure, ecologists have been ... -
