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 ... -

Genomic consequences of intensive inbreeding in an isolated wolf population
Kardos, Marty; Åkesson, Mikael; Fountain, Toby; Flagstad, Øystein; Liberg, Olof; Olason, Pall; Sand, Håkan; Wabakken, Petter; Wikenros, Camilla; Ellegren, Hans (Journal article, 2017)Inbreeding (mating between relatives) is a major concern for conservation as it decreases the fitness of offspring and can increase the extinction risk of populations. While pedigrees have traditionally been used to measure ... -
Integrated population models poorly estimate the demographic contribution of immigration
Paquet, Matthieu; Knape, Jonas; Arlt, Debora; Forslund, Pär; Pärt, Tomas; Flagstad, Øystein; Jones, Carl; Nicoll, MAC; Norris, K; Pemberton, Josephine M.; Sand, Håkan; Svensson, Linn; Tatayah, Vikash; Wabakken, Petter; Wikenros, Camilla; Åkesson, Mikael; Low, Matthew (Peer reviewed; Journal article, 2021)1. Estimating the contribution of demographic parameters to changes in population growth is essential for understanding why populations fluctuate. Integrated population models (IPMs) offer a possibility to estimate the ... -
Let’s stay together? Intrinsic and extrinsic factors involved in pair bond dissolution in a recolonizing wolf population
Milleret, Cyril; Wabakken, Petter; Liberg, Olof; Åkesson, Mikael; Flagstad, Øystein; Andreassen, Harry Peter; Sand, Håkan (Journal article; Peer reviewed, 2016)For socially monogamous species, breeder bond dissolution has important consequences for population dynamics, but the extent to which extrinsic or intrinsic population factors causes pair dissolution remain poorly understood, ... -
Predation of endangered Arctic foxes by Golden eagles: What do we know?
Jackson, Craig Ryan; Rød-Eriksen, Lars; Mattisson, Jenny; Flagstad, Øystein; Landa, Arild; Miller, Andrea; Eide, Nina Elisabeth; Ulvund, Kristine R. (Peer reviewed; Journal article, 2023)Dedicated conservation efforts spanning the past two decades have saved the Fennoscandian Arctic fox (Vulpes lagopus) population from local extinction, and ex-tensive resources continue to be invested in the species' ... -
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. ... -
