Abstract
Reciprocity allows animals to balance the costs and benefits of cooperative interactions by switching roles over time. Reciprocity can be based on two different processes: a within-dyad process based on temporal relations between cooperative events (partner control) and an across-dyad process based on preferences for the most cooperative partners (partner choice). The relative roles of the two processes remain debated. The aim of our study was to assess how the opportunity of interaction modulates grooming reciprocity in wild Geoffroy’s spider monkeys (Ateles geoffroyi), a species with low grooming rates and variable opportunities for group members to interact due to a high degree of fission-fusion dynamics. We investigated the roles of the aforementioned processes in grooming reciprocity, and the factors affecting them. Receiving grooming increased the probability of immediately returning grooming to the same partner (within-dyad temporal relations between cooperative events). In contrast, we found no evidence that spider monkeys directed most of their grooming to those individuals from which they received most grooming during the entire study period (across-dyad preferences for the most cooperative partners). The probability of returning grooming to the same partner was higher for dyads that spent less time together in the same subgroup, but was unaffected by maternal kinship. Our results suggest the opportunity to interact is a potent modulator of reciprocity. In species characterized by a high degree of fission-fusion dynamics and low grooming rates, short-term reciprocation based on partner control can be favored at the expense of a longer-term process based on partner choice.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
