Pumas (Puma concolor) and black bears (Ursus americanus) are large carnivores that may influence scavenger population dynamics. We used motion-triggered video cameras deployed at deer carcasses to determine how pumas and black bears affected three aspects of carrion acquisition by scavengers: presence, total feeding time, and mean feeding-bout duration. We found that pumas were unable to limit acquisition of carrion by large carnivores but did limit aspects of carrion acquisition by both birds… 

Gifts of an enemy: scavenging dynamics in the presence of wolves (Canis lupus)

Carrion represents an important resource for carnivores. Examining competition for carrion in a risk–reward framework allows for a better understanding of how predator guilds compete for and benefit

Top carnivore decline has cascading effects on scavengers and carrion persistence

It is shown that mesopredators consume more carrion in areas where devils have declined, suggesting a relaxed landscape of fear where devils are suppressed and broad relevance to the vast areas of the world that have suffered carnivore declines.


Abstract Many avian and mammalian predators are facultative scavengers and will opportunistically forage from carcasses. A food source as large as a whale carcass could be valuable to wildlife

Are pumas subordinate carnivores, and does it matter?

Until the time that the authors understand whether competitive effects are additive with human management, or even potentially synergistic, they encourage caution among managers responsible for determining harvest limits for pumas and other subordinate, apex carnivores in areas where they are sympatric with dominant species.

Vertebrate scavenger guild composition and utilization of carrion in an East Asian temperate forest

It is found that mammals were more frequent scavengers than birds and also fed for longer durations than other scavengers, suggesting that there is a facultative scavenger guild composed mainly of mammals in the forest ecosystem and that carcass utilization by birds was restricted to only forest species.

Enemies with benefits: integrating positive and negative interactions among terrestrial carnivores.

An integrative framework and synthesized data from 256 studies of intraguild predation, scavenging, kleptoparisitism and resource availability are developed, suggesting that the ecosystem service of mesocarnivore suppression provided by large carnivores is strong and not easily replaced by humans.

Is there anybody out there? Occupancy of the carnivore guild in a temperate archipelago

Carnivores are important components of ecological communities with wide-ranging effects that vary with carnivore size, natural history, and hunting tactics. Researchers and managers should strive to



Trophic Facilitation or Limitation? Comparative Effects of Pumas and Black Bears on the Scavenger Community

It is suggested that scavengers have species-specific adaptions to exploit carrion despite large carnivores, and thatLarge carnivores influence the structure and composition of scavenger communities.

Patterns of scavenger arrival at cheetah kills in Serengeti National Park Tanzania

Scavenging by large-bodied vertebrates is observed in many ecosystems but has rarely been quantified. Here we document the timing and order of scavenger arrival at 639 cheetah kills in Serengeti

The noble cats and the big bad scavengers: effects of dominant scavengers on solitary predators

It is indicated that prey loss to dominant scavengers is a widespread phenomenon among felids worldwide, including forest habitats, and suggested that ursid scavenging, by promoting the hunting of smaller prey, may have played an important role in the evolution of the Lynx genus as well as other predators in the Holarctic.

Seasonal variation in the feeding ecology of pumas (Puma concolor) in northern California

Pumas killed black-tails deer at higher elevations in summer than in winter, spring, or autumn, and the elevations correlated significantly with seasonal elevations used by black-tailed deer, suggesting that pumas exhibited seasonal foraging behaviours and tracked prey availability in a system with migrating prey.

Table scraps: inter-trophic food provisioning by pumas

Using new GPS technology, it is discovered that pumas in Patagonia provided 232 ± 31 kg of edible meat/month/100 km2 to near-threatened Andean condors and other members of a diverse scavenger community, highlighting the keystone role large, solitary felids play in natural systems.

Comparative Patterns of Predation by Cougars and Recolonizing Wolves in Montana's Madison Range

It is concluded that shifts by prey toStructurally complex refugia were attempts by formerly naïve prey to lessen predation risk from wolves; nevertheless, shifting to more structurally complexRefugia might have made prey more vulnerable to cougars.

Wolves-coyotes-foxes: a cascade among carnivores.

It is shown that wolves suppress coyote populations, which in turn releases foxes from top-down control by coyotes, and heavy predation by abundant small predators might be more similar to the historical ecosystem before top-predator extirpation.

American black bear predation of an adult white-tailed deer

Based on the condition of the carcass, physical evidence at the site, and the similarity of this predation to reported black bear predations, it is suggested this deer was attacked and killed by a black bear.

Trophic facilitation by introduced top predators: grey wolf subsidies to scavengers in Yellowstone National Park

It is demonstrated that wolves increase the time period over which carrion is available, and change the variability in scavenge from a late winter pulse dependent primarily on abiotic environmental conditions to one that is relatively constant across the winter and primarily dependent on wolf demographics.
