Ausilio, Giorgia; Sand, Håkan; Månsson, Johan; Mathisen, Karen Marie; Wikenros, Camilla (Peer reviewed; Journal article, 2021)In recent years, large predators have made a comeback across large parts of Europe.

Environmental and anthropogenic features mediate risk from human hunters and wolves for moose
Ausilio, Giorgia; Wikenros, Camilla; Sand, Håkan; Wabakken, Petter; Eriksen, Ane; Zimmermann, Barbara (Peer reviewed; Journal article, 2022)Landscape characteristics, seasonal changes in the environment, and daylight conditions influence space use and detection of prey and predators, resulting in spatiotemporal patterns of predation risk for the prey.

Wikenros, Camilla; Sand, Håkan; Månsson, Johan; Maartmann, Erling; Eriksen, Ane; Wabakken, Petter; Zimmermann, Barbara (Peer reviewed; Journal article, 2020)Predation from large carnivores and human harvest are the two main mortality factors afecting the dynamics of many ungulate populations. We examined long-term moose (Alces alces) harvest data from two countries that share ... -
Individual variation in predatory behavior, scavenging and seasonal prey availability as potential drivers of coexistence between wolves and bears
