Encounter Competition between a Cougar, Puma concolor , and a Western Spotted Skunk, Spilogale gracilis

The observation of a series of encounters in which a Western Spotted Skunk temporally usurped the carcass from the Cougar is the largest reported size differential of a mammalian species engaging in successful encounter competition.



Common ravens, Corvus corax, preferentially associate with grey wolves, Canis lupus, as a foraging strategy in winter

It is shown that ravens preferentially associate with wolves in both the presence and absence of food, resulting in the discovery of carcasses and suppression of ravens' innate fear of novel food sources.

Hunting Associations between Badgers (Taxidea taxus) and Coyotes (Canis latrans)

Overall, prey vulnerability appeared to increase when both carnivores hunted in partnership, and Coyotes associating with badgers appeared to hunt Uinta ground squirrels more effectively than lone coyotes.

Interference interactions, co‐existence and conservation of mammalian carnivores

A range of empirical examples are provided that together demonstrate that interference interactions have very important implications on carnivore demography and further research into the temporal and spatial aspects of co-existence are required if diverse guilds and communities are to be conserved.

Coyote-badger associations

— Four observations made in Jackson Hole, Wyoming, indicate that coyote-badger associations are best considered as phoretic (accidental and nonobligatory) rather than a form of social symbiosis as

Effect of raven Corvus corax scavenging on the kill rates of wolf Canis lupus packs

Raven-wolf competition is highest for small packs, where ravens manage to remove up to 75% of the edible biomass and very low for large packs whereRavens hardly manage toremove any edible biomass, and when raven consumption rate varies with pack size can match the observed pattern.
