    • Litter loss triggers estrus in a nonsocial seasonal breeder 

      Steyaert, Sam; Swenson, Jon; Zedrosser, Andreas (Journal article; Peer reviewed, 2014)
      Sexually selected infanticide (SSI) is often presumed to be rare among seasonal breeders, because it would require a near immediate return to estrus after the loss of an entire litter during the mating season. We evaluated ...

      Background In mammals, the hibernating state is characterized by biochemical adjustments, which include metabolic rate depression and a shift in the primary fuel oxidized from carbohydrates to lipids. A number of studies ...

    • Movement and habitat selection of a large carnivore in response to human infrastructure differs by life stage

      Large protected areas are often considered to be as important as population size in reducing extinction risk for large carnivores. However, the effectiveness of protected areas for large carnivore survival has rarely been ...

    • Phylogeography, genetic diversity, and connectivity of brown bear populations in Central Asia 

      Tumendemberel, Odbayar; Zedrosser, Andreas; Proctor, Michael F.; Reynolds, Harry V.; Adams, Jennifer R.; Sullivan, Jack M.; Jacobs, Sarah J.; Khorloojav, Tumennasan; Tserenbataa, Tuya; Batmunkh, Mijiddorj; Swenson, Jon; Waits, Lisette P. (Peer reviewed; Journal article, 2019)
      Knowledge of genetic diversity and population structure is critical for conservation and management planning at the population level within a species’ range. Many brown bear populations in Central Asia are small and ...

    • Proteolysis inhibition by hibernating bear serum leads to increased protein content in human muscle cells 

      Chanon, Stéphanie; Chazarin, Blandine; Toubhans, Benoit; Durand, Christine; Chery, Isabelle; Robert, Maud; Vieille-Marchiset, Aurélie; Swenson, Jon; Zedrosser, Andreas; Evans, Alina; Brunberg, Sven; Arnemo, Jon Martin; Gauquelin-Koch, Guillemette; Storey, Kenneth B.; Simon, Chantal; Blanc, Stéphane; Bertile, Fabrice; Lefai, Etienne (Journal article; Peer reviewed, 2018)
      Muscle atrophy is one of the main characteristics of human ageing and physical inactivity, with resulting adverse health outcomes. To date, there are still no efficient therapeutic strategies for its prevention and/or ...

    • Scent-sniffing dogs can discriminate between native Eurasian and invasive North American beavers 

      Rosell, Frank; Cross, Hannah; Johnsen, Christin Beate; Sundell, Janne; Zedrosser, Andreas (Peer reviewed; Journal article, 2019)
      The invasion of a species can cause population reduction or extinction of a similar native species due to replacement competition. There is a potential risk that the native Eurasian beaver (Castor fiber) may eventually be ...
