What is Predation risk and the interspecific association of two Brazilian Atlantic forest primates in Cabruca agroforest about?

## Abstract Forming interspecific associations is one of many strategies adopted by primates in order to avoid predation. In addition to improved predator detection and avoidance, benefits of interspecific associations relate to improved foraging efficiency. In this study we tested these two hypotheses explaining associations between the endangered golden‐headed lion tamarin, __Leontopithecus chrysomelas__ and the sympatric Wied's marmoset, __Callithrix kuhlii__. We estimated predation risk by recording the number of encounters between lion tamarins and potential predators in __cabruca__ agroforest (shaded cacao plantation) and in mosaic forest (a mix of __cabruca__, primary and secondary forest). To evaluate if the association between the two species was related to foraging benefits we recorded the number of associations between the two species when the lion tamarins were eating and when they were not eating. To test if the association occurred to improve predator detection and avoidance, we evaluated if associations between the species were more frequent in areas with higher predation risk and during the part of the day when predation risk is higher. We also compared the number o
