title: Data from: Jaguar-white lipped peccary dynamic interaction index and landscape structures

description: 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 addition, our results show an increased frequency of
 jaguar-peccary interactions under low white-lipped peccary densities.
 These insights enhance our understanding of the Pantanal's
 predator-prey dynamics, highlighting spatial-temporal movement patterns.
 Considering this, we can better inform conservation strategies by
 identifying zones that facilitate these interactions. Emphasizing what is
 the landscape structure and the prey density roles in this interaction
 contributes to preserving this ecosystem's delicate predator-prey
 balance. In conclusion, our findings show for the first time the movement
 interaction of these two species that are currently threatened, and
 conserving them and their natural habitats is vital for maintaining the
 Pantanal's ecological balance.
description: <strong>Jaguar and White-lipped Peccary Movement
 Dataset</strong> 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). <strong>Species Interaction
 Analysis</strong> 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).
 <strong>Environmental Variables</strong>
 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.
