Jaguars (Panthera onca) and pumas (Puma concolor) coexist throughout the Neotropics. Using camera trapping in four Brazilian biomes, we compare the daily activity patterns of the jaguar and puma, and their relationships with their main prey species. We used a kernel density method to quantify daily activity patterns and to investigate overlap between these predators and their main prey. Both cats showed intensive nocturnal and crepuscular activity (0.69 and 0.14 kernel density, respectively… 

Jaguar interactions with pumas and prey at the northern edge of jaguars’ range

It was found that both predators were more likely to co-occur together than to be found independently, and so the hypothesis that jaguars were the dominant species in this unique ecosystem was rejected.

Temporal and spatial segregation of top predators (Felidae) in a Mexican tropical Biosphere Reserve

Jaguars, Panthera onca (Linnaeus, 1758), and pumas, Puma concolor (Linnaeus, 1771) are the largest felids in the neotropics. Both can overlap in niche axes (time, space and prey), and are therefore

Puma activity patterns and temporal overlap with prey in a human‐modified landscape at Southeastern Brazil

The results suggested that males engaged in mostly nocturnal behavior while females were active both at night and day hours, suggesting that prey availability might influence puma activity or that pumas opportunistically prey upon species with similar activity pattern.

The activity of jaguars and pumas overlapped extensively and followed those of some of their potential prey, suggesting a potential for competition.

Exotic Prey Facilitate Coexistence between Pumas and Culpeo Foxes in the Andes of Central Chile

High spatial overlap and positive associations between detection of the carnivores lending little support for spatial segregation are found, and relatively low dietary overlap is found indicating niche segregation likely occurs along the dietary axis.

Spatiotemporal patterns of wolf, mesocarnivores and prey in a Mediterranean area

In a prey-rich community including an apex predator, three wild ungulates and several mesomammals, a substantial temporal overlap between wolves and wild boar, porcupines and mesocarnivores is detected and a negative temporal association between the predator and its main prey is detected.

Ecosystems in the northern Andes face unprecedented habitat loss. Pumas are the top predators in the region and exert key ecological functions, such as population control and resource facilitation.

Mesocarnivore activity patterns in the semiarid Caatinga: limited by the harsh environment or affected by interspecific interactions?

Nighttime-only activity comparisons showed that activity of oncillas differed from that of both larger mesocarnivores and jaguar activity, suggesting temporal segregation, and future studies in arid regions should consider climatic factors when estimating activity patterns.

Temporal niche overlap among mesocarnivores in a Caatinga dry forest

Mesocarnivores did not exhibit a significant synchrony of their activity with any of the preys evaluated, with the exception of jaguarundi, which significantly overlapped its distribution of activity with some preys.
