Carrion odor and cattle grazing [PDF]

open access: yesCommunicative & Integrative Biology, 2013
Recently, it has been proposed on theoretical grounds that carrion odor from flowers may not only attract pollinators, but also repel mammalian herbivores. Two grazing experiments involving 16 to 26 cattle heads per year, one for eight years (1982-1989) and the other for seven (1994-2000), in a region with no large carnivores that could influence ...

Vertebrate scavenging dynamics differ between carnivore and herbivore carcasses in the northern boreal forest

open access: yesEcosphere, 2021
Vertebrate scavenging can impact food web dynamics, but our understanding of this process stems predominantly from monitoring herbivore carrion and extrapolating results across carcass types.
