      Climate change is altering the reproductive phenology of many organisms, but the factors that influence the timing of gestation in ursids are still poorly understood. Higher temperatures in spring are already causing an ...

    • High concentrations of lead (Pb) in blood and milk of free-ranging brown bears (Ursus arctos) in Scandinavia 

      Fuchs, Boris; Thiel, Alexandra; Zedrosser, Andreas; Brown, Ludovick; Hydeskov, Helle Bernstorf; Rodushkin, Ilia; Evans, Alina; Boesen, Amanda Høyer; Græsli, Anne Randi; Kindberg, Jonas; Arnemo, Jon Martin (Peer reviewed; Journal article, 2021)
      Exposure to lead (Pb) is a global health problem for both humans and wildlife. Despite a dramatic decline in human Pb exposure following restrictions of leaded gasoline and industry and thereby an overall reduction of Pb ...
