     With an ever-growing human population, interactions between humans and nonhuman primates in shared interfaces are common and can lead to a variety of types of conflict (e.g., stealing goods and crop raiding generating financial losses; severe physical aggressions generating health risks). Disentangling the drivers of such conflict remains critical to their mitigation. Recent studies, however, have mainly focused on general patterns of interactions neglecting inter-individual differences. To address this gap, we assessed the drivers of conflict with humans among three groups of urban dwelling long-tailed macaques in Malaysia. Individual factors such as dominance rank and sex as well as within group aggression patterns are recorded and evaluated as potential drivers of conflict. Preliminary analysis of 273 inter-species aggressive events collected during focal follows of 74 macaques indicated that primate-to-human aggression was mainly influenced by the monkeys’ sex, with males being more aggressive towards humans than females (t(3)= 3.92, p < 0.001). Male, compared to female, macaques also tended to be aggressed more frequently by humans (t(3) = 1.74, p=0.08). In contrast, neither dominance rank nor their propensity for aggression towards other monkeys significantly predicted human-macaque aggressive interactions. Ongoing research will address untangling the dynamic interplay between these aggressive encounters and assess whether human-macaque interactions are influenced by suites (rather than single) of attributes (e.g. human socioeconomic status, macaque personality).
