(Peer reviewed; Journal article, 2020)
      The organization of ecological assemblages has important implications for ecosystem functioning, but little is known about how scavenger communities organize at the global scale. Here, we test four hypotheses on the factors ...
    • Of wolves and bears: Seasonal drivers of interference and exploitation competition between apex predators
