Some social species exhibit high levels of fission–fusion dynamics (FFD) that improve foraging efficiency. In this study, we shed light on the way that FFD allows animal groups to cope with fluctuations in fruit availability. We explore the relative contribution of fruit availability and social factors like sex in determining association and proximity patterns in spider monkeys. We tested the influence of fruit availability and social factors on the association and proximity patterns using three‐year data from a group of spider monkeys in the Yucatan Peninsula of Mexico. We identified subgroup members and estimated their Interindividual distances through instantaneous scan sampling. We evaluated fruit availability by monitoring the phenology ofthe 10 most important food tree species for spider monkeys in the study site. Social network analyses allowed us to evaluate association and proximity patterns in subgroups. We showed that association patterns vary between seasons, respond to changes in fruit availability, and are influenced by the sex of individuals, likely reflecting biological and behavioral differences between sexes and the interplay between ecological and social factors. In contrast, proximity patterns were minimally affected by changes in fruit availability, suggesting that social factors are more important than food availability in determining cohesion within subgroups.

Resumen en inglés

Fission-fusion dynamics (FFD) encompass a behavioral strategy present in many animal species that reduces the costs and increases the benefits of group living. In this case study, we investigated how group characteristics (size and composition) and fission rates in spider monkeys varied in space and time with rainfall, fruit availability, and fruit variability in two sites, each presenting different characteristics regarding the distribution and size of food patches and rainfall. Habitat characteristics strongly influenced FFD in spider monkeys, particularly subgroup size and fission rate. Subgroup size varied with fruit availability and its variability, while fission rates varied with rainfall and fruit variability. However, both subgroup size and fission rate varied in opposite ways, depending upon habitat type. Subgroups tended to present stable mixed-sex composition regardless of fruit availability. We conclude that for spider monkeys, FFD are part of a flexible behavioral strategy to cope with a locally fluctuating environment and with different environments within the geographic range of the species.
