Research overview: grouping as anti-predator defense against felids
OverviewA survey of how prey use group living to reduce predation by cats, through the many-eyes effect, dilution, confusion and collective defense. Larger herds detect stalking felids sooner and dilute indiv…
Research overview: hunting success and group size in lions
OverviewA survey of how cooperative group hunting affects capture success in lions, one of the few social felids. Evidence shows that hunting success often increases with group size for large or difficult pre…
Research overview: intraguild predation between felids and canids
OverviewA survey of the lethal interactions between cats and dogs that share prey and space, a major structuring force in carnivore communities. Lions and hyenas kill wild dogs and cheetahs; pumas and coyotes…
Research overview: kleptoparasitism among African large carnivores
OverviewA survey of the pervasive theft of kills within the African large-carnivore guild, where lions, spotted hyenas, leopards, cheetahs and wild dogs constantly contest carcasses. The direction and outcome…
Research overview: kleptoparasitism rates on cheetah kills
OverviewAn overview of how often cheetahs lose their kills to lions, hyenas and other competitors, and the consequences for cheetah foraging. Because cheetahs are exhausted after high-speed pursuits and canno…
Research overview: lion functional response to migratory wildebeest
OverviewAn overview of how resident lions respond to the dramatic seasonal pulses of migratory wildebeest and zebra that pass through their territories. Because lions are territorial and cannot follow the mig…
Research overview: lion predation impact on buffalo populations
OverviewA survey of the predator-prey relationship between lions and African buffalo, a preferred large prey whose size and defensive behavior make it both rewarding and dangerous to hunt. Lions, especially m…
Research overview: lunar and nocturnal effects on felid hunting
OverviewA survey of how darkness and the lunar cycle influence the hunting success and behavior of largely nocturnal cats. Many felids hunt more successfully on dark nights when reduced visibility favors the…
Research overview: mesopredator release following apex felid decline
OverviewAn overview of how the loss of large cats such as lions, tigers and pumas can unleash smaller predators with cascading consequences for biodiversity. When apex felids decline, the intermediate carnivo…
Research overview: metabolic constraints and kill frequency in felids
OverviewA survey of how a cat's metabolic needs and prey size determine how often it must kill. Larger felids require more total energy but extract it from larger carcasses, so kill frequency scales with the…
Research overview: nonconsumptive (risk) effects of felids on prey
OverviewA survey of how cats influence prey populations through fear and disturbance rather than direct killing. Risk effects include reduced foraging, heightened vigilance, altered habitat use, physiological…
Research overview: ontogenetic diet shifts in growing felids
OverviewAn overview of how the prey a cat takes changes as it grows, learns to hunt and gains the size and strength to subdue larger prey. Young felids first depend on prey provided by their mother, then prac…
Research overview: optimal prey size and energetics in big cats
OverviewAn overview of how energetic costs and benefits shape the prey sizes big cats prefer to hunt. Optimal foraging predicts that predators target prey large enough to yield a high energy return per kill y…
Research overview: predation on neonate ungulates by cats
OverviewA survey of how felids exploit the seasonal pulse of newborn ungulates, a period of high vulnerability that can dominate annual recruitment losses. During calving and fawning seasons, abundant, hidden…
Research overview: predator odor and prey foraging suppression
OverviewAn overview of how the scent of felid predators alone can suppress prey foraging, movement and reproduction, demonstrating nonconsumptive effects without any direct attack. Prey detect chemical cues o…
Research overview: predicting carnivore density from prey biomass
OverviewA survey of the strong, general relationship between the abundance of prey and the density of the carnivores that depend on them, a cornerstone of predator ecology. Across species and systems, predato…
Research overview: prey density thresholds for felid persistence
OverviewA survey of the minimum prey abundance large cats need to maintain viable populations and why prey depletion is a leading cause of felid decline. Because predator density scales with prey biomass, the…
Research overview: prey escape tactics and felid capture success
OverviewA survey of the anti-predator escape behaviors prey use once detected or attacked by cats and how they determine the outcome of a hunt. Prey employ rapid acceleration, unpredictable zig-zagging, stott…
Research overview: prey vigilance and anti-predator behavior toward cats
OverviewAn overview of the behavioral defenses ungulates and other prey deploy against felid predators, from vigilance scanning to alarm signaling and habitat avoidance. Because cats are stealthy ambush hunte…
Research overview: prey-handling time and consumption rates in big cats
OverviewA survey of how big cats process and consume their kills, and why handling time matters for kill-rate estimation and competition. Larger carcasses take longer to consume and force predators to remain…
Research overview: prey-selectivity indices in felid diet studies
OverviewA methodological survey of the indices used to measure whether felids prefer or avoid prey relative to availability, including the Jacobs index, Ivlev's electivity and related measures central to the…
Research overview: prey-size range and predator body-mass scaling
OverviewAn overview of how the range of prey sizes a felid exploits scales with its own body mass, producing the nested prey-size structure of carnivore communities. Larger cats not only take larger average p…
Research overview: scavenging contributions to felid diets
OverviewAn overview of how much carrion features in the diets of cats traditionally viewed as pure hunters. While felids are generally more reliant on fresh kills than canids or hyaenids, many will scavenge o…
Research overview: seasonal variation in felid prey selection
OverviewAn overview of how the prey cats select shifts through the year with prey vulnerability, migration, birth pulses and weather. Many felids exploit seasonal ungulate calving and fawning peaks, when abun…
Research overview: selection for vulnerable prey classes by felids
OverviewAn overview of the long-debated tendency of cats to kill the young, old, sick and injured disproportionately, and what it implies for predation impact. If predators chiefly remove individuals with low…
Research overview: sexual differences in prey selection in lions
OverviewA survey of how male and female lions differ in the prey they hunt and the habitats in which they hunt, driven by pronounced sexual size dimorphism. Larger, more powerful males are better able to tack…
Research overview: solitary versus cooperative hunting success in felids
OverviewAn overview comparing the hunting effectiveness of solitary felids with the cooperative hunting of lions, addressing why most cats hunt alone. Solitary ambush hunting suits stalking predators that tar…
Research overview: spatial avoidance of lions by cheetahs
OverviewAn overview of how cheetahs reduce the risk of intraguild predation and kleptoparasitism by avoiding lions across space and time. As a subordinate cursorial predator, the cheetah suffers heavy cub mor…
Research overview: stable isotope analysis of felid diets
OverviewA survey of how stable isotope ratios of carbon, nitrogen and other elements in tissues reconstruct the diets and trophic positions of cats. Because isotopic signatures of prey are passed to predators…
Research overview: stalking distance and hunting-habitat selection
OverviewAn overview of how ambush felids select hunting habitat to minimize the distance over which they must close on prey undetected. Because capture success drops sharply with the length of the final rush,…
