Jaguar-white lipped peccary dynamic interaction index and landscape structures

Understanding how the landscape influences the distribution and behavior of predators and prey gives us insights into the spatial dynamics of their interactions and the factors that shape their populations across space and time. In this study, we analyzed the interactions between jaguars (Panthera onca) and white-lipped peccaries (Tayassu pecari) at different forest and grassland distances and under varying predator or prey densities. To investigate the influence of these variables on interactions, we considered analytical contexts “The Dynamic Interaction Index,” which represents attraction or avoidance behavior. We also calculated the proximity between predator and prey over time by assessing the distance among their locations. By analyzing GPS-movement data from three jaguars and five peccaries over 44 days, we observed that close distances were uncommon, and distances within a 3 to 5 km range were more prevalent. Most interactions occurred at greater distances from grasslands. In ad..., Jaguar and White-lipped Peccary Movement Dataset Movement data for three jaguars and five white-lipped peccaries were collected between August 17th and September 30th, 2015, in the Southern Pantanal (Morato et al., 2018; Oshima, 2019).
Species Interaction Analysis We analyzed 525 predator-prey location pairs using the Dynamic Interaction Index (DII) to classify attraction, avoidance, or random movement. Distance between entities was computed with a 5000-meter threshold using the wildlifeDI package in R (Long et al., 2022).
Environmental Variables Environmental variables (forest and grassland data) from the Mapbioma platform (2015) were analyzed with LSMetrics software. These variables were crucial for habitat selection. Predator and prey densities were estimated using kernel density in QGIS 3.10.7.

This dataset includes information on six interactions between jaguars and white-lipped peccaries in the Pantanal region during the dry season, where data were spatially and temporally overlapped to calculate the dynamic interaction index.
