Age at first reproduction in wolves: Different patterns of density dependence for females and males
Wikenros, Camilla; Gicquel, Morgane; Zimmermann, Barbara; Flagstad, Øystein; Åkesson, Mikael (Peer reviewed; Journal article, 2021)Age at first reproduction constitutes a key life-history trait in animals and is evolutionarily shaped by fitness benefits and costs of delayed versus early reproduction. The understanding of how intrinsic and extrinsic ... -

Først ... -
Poaching-related disappearance rate of wolves in Sweden was positively related to population size and negatively to legal culling
Liberg, Olof; Suutarinen, Johanna; Åkesson, Mikael; Andrén, Henrik; Wabakken, Petter; Wikenros, Camilla; Sand, Håkan (Peer reviewed; Journal article, 2020-03-14)Poaching is an important limiting factor for many large carnivore populations worldwide and the effect that legal culling has on poaching rate on wolf (Canis lupus) is debated. We used data linked to population monitoring ... -
Scavenging patterns of an inbred wolf population in a landscape with a pulse of human-provided carrion
Wikenros, Camilla; Di Bernardi, Cecilia; Zimmermann, Barbara; Åkesson, Mikael; Demski, Maike; Flagstad, Øystein; Mattisson, Jenny; Tallian, Aimee Grace; Wabakken, Petter; Sand, Håkan (Peer reviewed; Journal article, 2023)Scavenging is an important part of food acquisition for many carnivore species that switch between scavenging and predation. In landscapes with anthropogenic impact, humans provide food that scavenging species can utilize. ... -
