Interspecific killing has been documented in many different pairs of carnivores and is more likely when the larger Interference competition is an important process working to shape species is 2–5.4 times the mass of the victim species, or when the mammalian carnivore communities (Palomares and Caro 1999; larger species is a hypercarnivore (Donadio and Buskirk 2006; de Donadio and Buskirk 2006). Dominance in these interactions is Oliveria and Pereira 2014). Carnivores may reduce the likelihood often asymmetric based on body size (Palomares and Caro 1999; de of these types of encounters through the partitioning of habitat or Oliviera and Pereira 2014), and the threat of intraguild strife from temporal activity.
