“…Dentro de la primera categoría, 33 investigaciones se enfocaron en describir los hábitos de alimentación del jaguar, de los cuales, 26 estudios evaluaron el consumo de las presas del jaguar en diferentes escenarios, siete determinaron los hábitos de depredación del jaguar sobre algunas especies acuáticas. (58)(59)(60)(61)(62)(63)(64) Los 12 estudios restantes que evaluaron las fuentes naturales de alimentación analizaron la variabilidad y disponibilidad de la base de presas del jaguar, cuyo término refiere la riqueza y la abundancia de las presas consumidas con más frecuencia por este felino. (65)(66)(67)(68)(69)(70)(71)(72)(73)(74)(75)(76) Por último, de las 12 publicaciones que se enfocaron en la depredación del ganado por parte del jaguar, siete estudios describieron y analizaron las características de los ataques, (77)(78)(79)(80)(81)(82)(83) mientras que los cinco restantes evaluaron los factores de riesgo de los ataques.…”

“…Más aún, los estudios que analizaron la depredación sobre especies acuáticas demuestran que los jaguares también consumen huevos de tortugas y tortugas adultas, así como huevos y ejemplares de crocodilios (Cocodrilia),(63,64) sin que esto represente una amenaza para dichas poblaciones. Además, los resultados sugieren que los jaguares suelen compartir presas con otros jaguares durante la temporada baja de anidación de la tortuga (58,59). En conjunto, los resultados de la presente revisión de alcance demuestran que los jaguares pueden presentar patrones diversos de consumo de presas, los cuales no solo dependen del tamaño de las mismas, sino que también varían…”

A scoping review was conducted to map, summarize, and understand the extent of evidence on jaguar (Panthera onca) food resource use and its interaction with humans. A total of 105 studies were identified in electronic databases: 57 analyzed jaguar food resource use, and 48 described jaguar interactions with humans. The studies were published in 51 journals, mainly in English, from 1993–2021 in 14/19 countries where jaguars live. The evidence demonstrated the variability and prey consumption of the jaguar; there are contrasting results regarding the diversity of prey consumed. The frequency of livestock predation was found to be related to the abundance and availability of natural prey and the distance of ranches from the jaguar habitat. The interaction of the jaguar with humans presented an interesting and contrasting picture, since the perception of the jaguar varied depending on the sociocultural context and the study site. The results showed a negative effect of human activities on the distribution and density of the feline, and there was evidence of poaching and attacks on humans, although the information was insufficient to determine the causes in depth. More research and dissemination are needed on these issues at the local level in the regions where the jaguar lives, as these are the areas where decisions and actions are needed to conserve the jaguar in coexistence with communities and livestock.

“…Indeed, peccaries have been documented as key prey items at sites across the jaguar range from Mexico to southern Brazil (e.g. Mexico [ 43 – 46 ], Costa Rica [ 47 , 48 ], Peru [ 49 ], Paraguay [ 50 ], Brazil [ 9 , 31 , 51 , 52 ]). Coatis, which comprised the majority of the non-armadillo small prey, were consumed by almost one-half (41%) of the sampled jaguars, and have been noted as common prey items in jaguar diet at sites in Mexico, Guatemala and Brazil [ 3 , 28 , 30 – 32 ].…”

Dietary similarity among jaguars (Panthera onca) in a high-density population

Prey remains found in carnivore scats provide generalised dietary profiles of sampled populations. The profile may be biased if individual diets differ and some individuals are over- or under-represented in the sample. Quantifying individual contributions allows us to recognise these potential biases and better interpret generalised profiles. Knowing the dietary differences or similarity between individuals can help us to understand selection pressures and identify drivers of distribution and abundance. Using the results of individual faecal genotyping, we re-interpreted our previously-published generalised dietary profile of an elusive, neotropical felid, the jaguar (Panthera onca; Foster et al. (2010)). We quantified individual sample sizes, assessed whether the generalised profile was influenced by the inclusion of scats originating from the same individual and prey carcass (pseudo-replication), and quantified the distribution of prey species among individuals. From an original sample of 322 jaguar scats from a high-density jaguar population in Belize, we identified 206 prey items (individual prey animals) in 176 independent scats representing 32 jaguars (26 males, 3 females, 3 unknown sex). The influence of pseudo-replication in the original dietary profile was minimal. The majority of scats (94%) came from male jaguars. Eight males accounted for two-thirds of the prey items, while 24 jaguars each contributed <5% of the prey items. With few exceptions, the jaguars followed the same broad diet, a 2:1:1 ratio of nine-banded armadillos (Dasypus noveminctus), other vertebrates ≤10kg, and ungulates, primarily peccaries (Tayassu pecari and Pecari tajacu). We noted prey switching between wild and domestic ungulates for individuals spanning protected forests and farmland. This first scat-based study exploring individual variation in jaguar diet highlights the importance of armadillos and peccaries for male jaguars in Belize, the need for research on their roles in supporting high-density jaguar populations, and the need for more data on female diet from across the jaguar range.
