ABSTRACT We examined the evidence supporting the hypothesis that jaguars (Panthera onca) have morphological and behavioural adaptations to facilitate reptile predation. Jaguars’ head and bite features show adaptations to durophagy (consumption of hard-integumented prey) that are very unusual within the genus Panthera. These include: thick canines, well-developed head muscles and a fatal bite directed to braincase or nape. These characteristics have been previously considered an adaptation for… 
What are jaguars eating in a half-empty forest? Insights from diet in an overhunted Caatinga reserve
It is demonstrated that jaguars are able to shift their diet to small prey when larger quarry is scarce, and subsisting in such a stressful trophic position may lead to decreased levels of recruitment and low emigration rate.
First records of Brazilian three-banded armadillo (Tolypeutes tricinctus, Mammalia, Cingulata, Chlamyphoridae) predation by jaguar (Panthera onca, Mammalia, Carnivora, Felidae)
It is argued that the jaguar Panthera onca may be the most adapted non-human predator to feed on T. tricinctus, and that the smaller body sizes of P. onca individuals in the Caatinga may increase their likelihood to feeding on smaller prey, including T.tricincts.
Mammalian Diversity and Matses Ethnomammalogy in Amazonian Peru Part 2: Xenarthra, Carnivora, Perissodactyla, Artiodactyla, and Sirenia
The principal contribution of this report consists in the natural history information compiled from the authors' Matses informants and the resulting overview of local community structure as defined by diurnal activity, locomotion, social behavior, and trophic relationships.
Large Felid Predators and “Man-Eaters”: Can We Successfully Balance Conservation of Endangered Apex Predators with the Safety and Needs of Rapidly Expanding Human Populations?
The large felid carnivores are among the most endangered, and the most challenging, species to conserve on this increasingly human-dominated planet. In modern times, large felid carnivores were
Chelonian Predation by Jaguars (Panthera onca)
A new record of freshwater turtle predation by the jaguar, Panthera onca, is presented in addition to a current review of chelonianpredation by this feline.
High moon brightness and low ambient temperatures affect sloth predation by harpy eagles
It is shown that even moderate seasonal variation in temperature can influence the relationship between a keystone tropical forest predator and a dominant prey item, and predator–prey ecology in the tropics can be modulated by subtle changes in environmental conditions.
Warped finite element models predict whole shell failure in turtle shells
The idea that warped FE models run with simplifying assumptions at least can provide useful information for comparative biomechanical studies is supported.


Prey Preferences of the Jaguar Panthera onca Reflect the Post-Pleistocene Demise of Large Prey
Jaguars have an unusual predator to prey body mass ratio, show limited effect of prey morphology as a driver of prey selection, lack evidence of optimal foraging beyond their preferred prey, and an absence of preferentially hunting on Cetartiodactyla herbivores.
Depredation by Jaguars on Caimans and Importance of Reptiles in the Diet of Jaguar
In the Mamirauá Sustainable Development Reserve in the western Brazilian Amazon, predation by jaguars on two species of caiman (Caiman crocodilus and Melanosuchus niger), which are abundant in this varzea habitat, is documented.
Comparative feeding ecology of felids in a neotropical rainforest

Analysis of scats 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.
Food habits of sympatric jaguars and pumas across a gradient of human disturbance
It is suggested that jaguar predation on cattle may be reduced by ensuring that game hunting is sustainable and potentially by augmenting forests within the human matrix with large wild ungulates.
Food habits of jaguars and pumas in Jalisco, Mexico
There was a high degree of overlap between jaguar and puma diets, but pumas had a broader food niche than jaguars, and their ability to exploit smaller prey may give them an advantage over jaguARS when faced with human-induced habitat changes.
Foraging ecology of jaguar (Panthera onca) and puma (Puma concolor) in hunted and non‐hunted sites within the Maya Biosphere Reserve, Guatemala
Jaguar and puma in both hunted and non-hunted sites obtained similar dietary contributions from large prey to their respective diets despite differences in the abundance of these prey species.
Food Habits and Livestock Depredation of Sympatric Jaguars and Pumas in the Iguaçu National Park Area, South Brazil
Degree of diet overlap between jaguar and puma in INP suggests that coexistence was likely driven by exploitative competition through some degree of food partitioning, and the importance of more actions toward increasing numbers of large ungulates to preserve the population of jaguars in InP is highlighted.
Prey preferences of the leopard (Panthera pardus)
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.
