Fredrik Dalerum

  • Research interests

    I am a terrestrial ecologist that focus my research efforts on predation processes, the biology and conservation of mammalian carnivores, and on functional aspects of biodiversity. I use a combination of empirical and theoretical methods to approach these topics. I am also interested questions related to sustainability.
