The social complexity hypothesis for communicative posits that animal societies with more complex systems require communication systems. We tested the on three macaque species vary in their degree of tolerance and complexity. coded facial behavior >3000 interactions across contexts (aggressive, submissive, affiliative) 389 animals, using Facial Action Coding System macaques (MaqFACS). quantified measures uncertainty: entropy, specificity, prediction error. found relative entropy was higher...
Abstract Understanding facial signals in humans and other species is crucial for understanding the evolution, complexity, function of face as a communication tool. The Facial Action Coding System (FACS) enables researchers to measure movements accurately, but we currently lack tools reliably analyse data efficiently communicate results. Network analysis can provide way use information encoded FACS datasets: by treating individual AUs (the smallest units movements) nodes network their...
There is a vast and ever-accumulating amount of behavioural data on individually recognised animals, an incredible resource to shed light the ecological evolutionary drivers variation in animal behaviour. Yet, full potential such lies comparative research across taxa with distinct life histories ecologies. Substantial challenges impede systematic comparisons, one which lack persistent, accessible standardised databases. Big-team approaches building databases offer solution facilitating...
Investigating causes and consequences of variation in hormonal expression is a key focus behavioral ecology. Many studies have explored patterns secretion the androgen testosterone male vertebrates, using challenge hypothesis (Wingfield, Hegner, Dufty, & Ball, 1990; The American Naturalist, 136(6), 829–846) as theoretical framework. Rather than classic association with sexual behavior, this predicts that high levels are associated male–male reproductive competition but also inhibit...
Abstract Nonhuman primates (NHPs) are widely studied across many scientific disciplines using a variety of techniques in diverse environments. Due to the wide scope NHP research, substantial overlap research topics and questions can occur, whose resulting evidence is synthesized by literature reviews. Identifying all relevant on particular topic involving NHPs be difficult time consuming. By adopting objective search development from systematic reviews, we developed filters detect...

Abstract Mammals living in stable social groups often mitigate the costs of group through formation bonds and cooperative relationships. The neuropeptide hormone oxytocin (OT) has been proposed to promote both bonding cooperation although only a limited number studies have investigated this under natural conditions. Our aim was assess role OT male Barbary macaques ( Macaca sylvanus ). First we tested for an effect affiliation - grooming triadic male-infant-male interactions with bond...
Abstract Neuroendocrine research on the formation of social bonds has primarily focused role nonapeptides. However, steroid hormones often act simultaneously to either inhibit or facilitate bonding. Testosterone is proposed mediate a trade-off between male mating effort and nurturing behavior; therefore, low levels are predicted during periods infant care In species where bonding support regulates hypothalamic-pituitary-adrenal axis activity, we also expect glucocorticoid be periods. We...

The development of methods to quantify hormones from non-invasively collected samples such as urine or feces has facilitated endocrinology research on wild-living animals. To ensure that hormone measurements are biologically meaningful, method validations highly recommended for each new species sample matrix. Our aim was validate three commonly used enzyme immunoassays (EIA), one analysis cortisol and two testosterone, assess adrenocortical gonadal activity, respectively, the male Barbary...
