Spatial organization and food habits of jaguars (Panthera onca) in a floodplain forest
For most carnivore populations, territoriality is the regulating social system ultimately determined by food abundance and/or strife. However, in some food-based territorial felid species such as the jaguar (Panthera onca), the influence of food availability on territoriality remains unclear and may be lessened because of a tendency for individuals to occur at high densities across the landscape. We examined spatial organization and use of food in a population of jaguars in the southern region of the Pantanal, Brazil (2003‐04). We predicted that if territoriality plays an important role in determining jaguar population dynamics, exclusive use of territories should be observed and thereby influence prey selection patterns. We determined that home range sizes were comparable between sexes and overlapped little at the core area level. Line transect surveys revealed that large mammals comprised the bulk of available wild prey for jaguars, and scat analysis indicated that jaguars relied mostly on large mammalian prey. The most common wild species killed by jaguars were capybara (Hydrochaeris hydrochaeris) and caiman (Caiman yacare). We estimated that the wild prey base was adequate to support the jaguar population. Larger wild prey species were considerably more likely to die from predation than from other causes, and predation was more likely to occur in jaguar core areas than in areas of home range overlap. Modest cattle depredation rates had little demographic importance to the local jaguar population. We conclude that spacing patterns in the local jaguar population were likely based on exclusion through territoriality rather than food limitation. https://www.semanticscholar.org/paper/Spatial-organization-and-food-habits-of-jaguars-in-Azevedo-Murray/09b2c7e5fd22dabed4bce99624ba5bc1b2bac823

Jaguar (Panthera onca) food habits in Atlantic rain forest of southeastern Brazil
Abstract: Between January and December 1996, the food habits of a relict population of jaguars were studied in 220 km(2) Linhares Forest Preserve, which comprises much of the remaining old-growth Atlantic Forest of Espirito Santo, Brazil. Fecal analysis indicated opportunistic feeding on 24 prey species (N = 101 scats). Mammals represented 87 percent of the total items, followed by reptiles (9.8%) and birds (2.8%). Considering prey weight, 23.4 percent of the items weighed 1-3 kg, 40.5 percent were 3-10 kg, and 27.7 percent weighed more than 10 kg. Analysis of relative prey frequency and biomass indicated that the diet was concentrated in two prey types: long-nosed armadillo and white-lipped peccary. Literature data suggest that forest jaguars rely on the same mammal prey over their entire geographic range.
Jaguar (Panthera onca) feeding ecology: distribution of predator and prey through time and space
Jaguars Panthera onca inhabiting tropical or subtropical evergreen moist forest have often been classified as opportunistic predators because they consume prey relative to its availability. However, these studies failed to address simultaneously the distribution of predator and prey through time and space, which may lead to an incomplete or erroneous understanding of jaguar foraging strategies. In this study, we reconstructed jaguar diet from scat, and used camera traps to investigate jaguar prey availability and the distribution of jaguar and its prey through space and time. We focused our examination of predator-prey temporal and spatial relations on forest infrastructure comprising man-made paths, small mammal trails, tapir Tapirus bairdi trail and trail-less, forested areas as they represent distinct habitats for prey selection. Overall, we observed high overlap between the prey used and available, suggestive of opportunistic foraging. However, jaguars exhibited selective tendencies in discriminating between larger prey. Jaguars used collared peccary Tayassu tajacu greater than its availability, while preying upon the equally abundant and similarly distributed white-lipped peccary Tayassu pecari and tapir less than predicted based upon availability. Armadillo Dasypus novemcinctus and paca Agouti paca, 56.6% of total consumption, were consumed relative to availability but exhibited low spatial overlap with jaguar. Armadillo and paca used trail-less, forested areas and small mammal trails not used by jaguar and were photographed more frequently at greater distances from man-made paths, major thoroughfares for jaguars. This study suggests that although forest jaguars use prey relative to its abundance, jaguars may rely on foraging strategies other than chance encounters for exploiting prey.

A crazy scene which we will probably never see again !! A freshly killed Tapir killed by a Jaguar. We were doing a Safari drive in Kaa Iya National Park when we saw a large amount of blood , upon further inspection we found this young Tapir which had recently been killed by a Jaguar. We waited for over 11 hours however as it was very windy the Jaguar knew we were in the area, so we left. A few hours later we returned to find the Tapir gone and the next day found the carcass a further 100 metres in the shrub. We have placed a camera trap in the area so will post images in the coming week once we retrieve the footage. Kaa Iya National Park never ceases to suprise.  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author Amazing photos of a large male Jaguar (Panthera onca) returning to feed on a Lowland Tapir (Tapirus terrestris) that it had recently killed... These images were captured by our friends from Proyecto Yaguareté in Argentina... Researchers have named this jaguar "Aratirí" (or Lightning) because of its abilities as a fast and powerful hunter... Tapirs typically weigh around 500 lbs., more than double the weight of an average-sized jaguar!  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author Photograph: Edsel Moraes Jr. A rare image of a jaguar carrying the body of an adult giant anteater it has killed.

Some research shows that jaguars in the cerrado may more frequently hunt giant anteaters than those in other ecosystems.  *This image is copyright of its original author

3 adult black caiman killed by jaguars with both being of unknown sex.
 *This image is copyright of its original author Between October 2001 and April 2004 we equipped and monitored 10 jaguars (5 adult males, 1 subadult male, and 4 adult females) with GPS collars. The subadult male as still with his mother and another subadult sibling; we therefore assigned those kills to his mother (adult female 5) and considered the kill rate to be that of a family group. Radiocollared jaguars were monitored for a total of 76 radiomonths. Continuous monitoring of individual cats varied from 1.5 to 24 months (Table 1); we were able to monitor 3–5 jaguars simultaneously during a single period. They hunted prey of good size and quite strong as wilds boars, caimans and anteaters.  *This image is copyright of its original author
