Implication

Comparative dietary study reveals high trophic overlap in sympatric jaguars and pumas, suggesting prey availability and habitat disturbance influence niche differentiation.

Key Points

Determine and compare the food habits and extent of dietary overlap between sympatric jaguars and pumas in developed and undeveloped regions of the Paraguayan Chaco.
Analyzed 280 carnivore scats using biochemical methods to identify species origin, attributing 106 samples to jaguars and 95 to pumas.
Quantified diet by item count and estimated prey biomass across three mammalian size categories (<1 kg, 1–15 kg, and >15 kg) as well as birds, reptiles, and insects across developed and undeveloped habitats.
Overall dietary overlap between jaguars and pumas was 65%, with both species sharing six of seven primary prey categories.
Mammals >15 kg comprised 27% of prey items but 53% of consumed biomass, while mammals <1 kg accounted for 43% of items and 15% of biomass.
No significant dietary differences occurred in the developed area, whereas in the undeveloped area, both cats consumed more small mammals and jaguars consumed more large prey than pumas.
