SummaryDiet and habitat use of jaguar, puma, and ocelot, and populations of their mammalian prey, were studied in an undisturbed rainforest in southeastern Peru. Analysis of scats (feces) showed terrestrial mammals to be the chief prey of all three felids, but reptiles and birds were also numerically important in the diets of ocelot and jaguar. Prey diversity is high and the cats evidently take any readily captured vertebrate. For major terrestrial mammal prey of felids, density, biomass, prey… Expand

Food Habits of Ocelots and Potential for Competition With Bobcats In Southern Texas
TLDR
The data suggest that bobcats also preyed more heavily on the largest rodents and less on the medium-sized rodents than ocelots did, and studies of the dietary differences when both or only one of the felid species is present in an area would allow the likelihood of negative impacts of competition to be fully evaluated.

Jaguar (Panthera onca) feeding ecology: distribution of predator and prey through time and space
TLDR
Although forest jaguars use prey relative to its abundance, jaguar may rely on foraging strategies other than chance encounters for exploiting prey, suggesting of opportunistic foraging. Expand
Relative abundance of mammalian species in a central Panamanian rainforest.
Abstract Mammals are understudied in the Neotropics with very little baseline distribution and abundance data available for many species. We quantified relative abundance of mammal species in centralExpand
Food Habits of an Endangered Carnivore, Cryptoprocta ferox, in the Dry Deciduous Forests of Western Madagascar
TLDR
The diet of fossas in a dry deciduous forest of western Madagascar is described, with a higher proportion of Tenrec in the former, and fewer lemurs in the latter, suggesting that they were living close to the maximum population density possible on the available prey. Expand
Ocelot (Leopardus pardalis) Food Habits in a Tropical Deciduous Forest of Jalisco, Mexico
TLDR
Evidence of subadult white-tailed deer was found in scats indicating that ocelots can either capture prey bigger than themselves or are using deer as carrion. Expand
Prey Abundance and Leopard Diet in a Plantation and Rainforest Landscape, Anamalai Hills, Western Ghats
TLDR
Diet of large carnivores (with a focus on leopards) is examined using scat analysis with DNA-based identification of predator species, and relative abundance of prey species in different land uses through transect surveys are estimated. Expand
Diets of three sympatric Neotropical small cats: Food niche overlap and interspecies differences in prey consumption
TLDR
The opportunistic feeding behavior and the abundance of their primary prey (cricetid rodents) seem to allow these small cats to be resilient despite severe anthropogenic disturbance in the study area, and guidelines for future studies are suggested in order to understand the dynamics of mammalian carnivores demography. Expand
Prey preferences of the leopard (Panthera pardus)
TLDR
This model will allow us to predict the diet of leopards in areas where dietary information is lacking, also providing information to assist wildlife managers and conservation bodies on predator carrying capacity and predator– prey interactions. Expand
Densities, habitat-use, and mesopredator release of the ocelot in Belize
To manage and protect an intact neotropical carnivore guild it is necessary to understand the relative importance of habitat selection and of intraguild competition to the ecology of individualExpand
Biogeographic variation of food habits and body size of the America puma
TLDR
The puma has the most extensive range of any terrestrial mammal in the Western Hemisphere, covering over 100° latitude, and food habits of different puma subspecies vary with latitude. Expand

Mammals and their biomass on a Brazilian ranch
TLDR
An analysis of food habits revealed several trends in resource use: terrestrial mixed browsers and grazers - tapir and deer - contributed most to the biomass; primary grazers were absent, except for the semi-aquatic capybara; and arboreal folivores were rare, comprising only howler monkey and porcupine, with 3% of the total biomass. Expand
On the Ecological Separation between Tigers and Leopards
TLDR
Coexistence in Chitawan is facilitated by a large prey biomass, a larger proportion of the ungulate biomass in the small size classes, and by the dense vegetation structure, and some consequences of predator size and the role of interspecific dominance are discussed. Expand
Observations on the Behavior of Rain Forest Peccaries in Perú: Why do White‐lipped Peccaries Form Herds?
TLDR
The ecology and behavior of Tayassu tajacu and T. pecari were studied for a total period of 16 months in the years 1975–1978 in the Manu National Park in southeastern Peru to suggest that individuals of this species were relatively sedentary. Expand
COMMUNITY STRUCTURE IN SYMPATRIC CARNIVORA
TLDR
It is demonstrated that weasel differ in their degree of specialization on mouse-sized food, larger weasels taking a greater size variety, which is possibly a coexistence-stabilizing force. Expand
Life History Patterns and the Comparative Social Ecology of Carnivores
TLDR
This work will primarily review field studies focusing on the variation in behavior, body size, and life histories and emphasize data collected on identified individuals that have been observed directly (sometimes supplemented by radio-tracking) over long periods of time. Expand

TLDR
Comparative studies of activity patterns, microhabitat preferences, foraging behaviour and diet indicate surprisingly broad overlap among small nocturnal carnivores along the niche dimensions investigated. Expand
