• Trophic cascades in a multicausal world: Isle Royale and Yellowstone (2014, background): “Grizzly bears have also benefitted from increased opportunities to scavenge carcasses produced by wolves (Wilmers et al. 2003a,b) and, perhaps, from increased berry production that was an indirect effect of reduced elk herbivory (Ripple et al. 2013).”
• Predation or scavenging? Prey body condition influences decision‐making in a facultative predator, the wolverine (2016, background): “Furthermore, the role of anthropogenic food resources in shaping predator–prey interactions should not be underestimated (Wilmers et al. 2003b, Rodewald et al. 2011).”
• Predicting the influence of wolf‐provided carrion on scavenger community dynamics under climate change scenarios (2006, methodology): “Winter carrion is crucial to the survival and productivity of many of these scavenger species (Newton et al., 1982; Swenson et al., 1986; Blanchard, 1987; Dhindsa & Boag, 1990; Crabtree & Sheldon, 1999; Wilmers et al., 2003a).”
• Trophic cascades in Yellowstone: The first 15 years after wolf reintroduction (2012, background): “…scavengers such as ravens (Corvus corax), bald eagles (Haliaeetus leucocephalus), and black-billed magpies (Pica hudsonia) due to subsidies from wolf-killed carcasses (Wilmers et al., 2003), and on smaller carnivores due to the killing of coyotes by wolves (Smith et al., 2003; Ripple et al., 2011).”
• Intrapopulation variation in gray wolf isotope (δ15N and δ13C) profiles: implications for the ecology of individuals (2005, background): “Wolf kills are also important sources of food for associated avian and mammalian scavengers (Wilmers et al. 2003).”
• Ecologically justified charisma: preservation of top predators delivers biodiversity conservation (2006, background): “Eighthly, top predators may indirectly provide essential resources for other species, such as carrion for scavengers (Wilmers et al. 2003).”
• Habitat heterogeneity and mammalian predator–prey interactions (2012, background): “Snow depth or dense undergrowth, for instance, may reduce the chances of finding a carcass by affecting the movement rates and distances travelled (Huggard 1993, Wilmers et al. 2003).”
