Abstract

Understanding how landscape structure influences predator-prey dynamics is critical for conservation. This study analyzed jaguar-peccary interactions, revealing uncommon close distances and prevalent 3-5 km ranges, especially away from grasslands. Low peccary densities increased interactions. Findings inform conservation strategies, highlighting landscape structure and prey density roles in maintaining Pantanal's balance.
