Scavenging by vertebrates: behavioral, ecological, and evolutionary perspectives on an important energy transfer pathway in terrestrial ecosystems

Abstract: Carrion use by terrestrial vertebrates is much more prevalent than conventional theory implies, and, rather than a curiosity of animal behavior, is a key ecological process that must be accounted for. Human aversion to rotted substances and difficulties associated with identifying scavenged material in studies of food habits have contributed to the relative lack of information concerning scavenging behavior in vertebrates. Several lines of evidence, however, suggest that carrion resources are more extensively … Show more

“…Numerous studies have been conducted in order to examine decomposition processes associated with plant-derived organic residues (Chander and Brookes,cadavers and cadaver components (e.g. skeletal muscle tissue, hair, bone) although animals regularly die in terrestrial ecosystems (DeVault et al, 2003). Of these studies, the vast majority are concerned with the activity of arthropods (e.g.…”

“…As a result, most large mammalian carnivores shift facultatively between hunting and scavenging depending on seasonal and regional variation of prey availability (Wilmers et al 2003;Wilson and Wolkovich 2011;Pereira et al 2013). A clearer perspective on carrion use by mammalian carnivores will improve our understanding of critical ecological processes, particularly those associated with energy flow and trophic interactions between individuals and species (DeVault et al 2003).…”

“…Mammalian carnivores are traditionally labeled as predators, but they do not usually pass by opportunities to consume carcasses when encountered (DeVault et al 2003;Selva et al 2005;Wilson and Wolkovich 2011). No mammals have evolved into obligate scavengers and even the most well adapted mammalian scavengers, such as hyenas, kill the majority of their food (Cooper et al 1999).…”
