Alpha male replacements and delayed dispersal in crested macaques ( Macaca nigra )
In species with a high male reproductive skew, competition between males for the top dominant position is high and escalated fights are common between competitors. As a consequence, challenges incur potentially high costs. Selection should favor males who time an alpha male challenge to maximize chances of a successful outcome minimizing costs. Despite the importance of alpha male replacements for individual males, we know little about the timing…
Feeding behavior and aggression in wild Siberut macaques ( Macaca siberu ) living under low predation risk
Investigating which factors influence feeding competition is crucial for our understanding of the diversity of social relationships. Socio-ecological models differ in their predictions whether predation risk directly influences feeding competition and which factors exactly predict contest competition. We investigated feeding competition in Siberut macaques (Macaca siberu), a species endemic to Siberut Island (West Sumatra, Indonesia). Siberut mac…
Modeling Primate Abundance in Complex Landscapes
Density Estimation of the Endangered Udzungwa Red Colobus (Procolobus gordonorum) and Other Arboreal Primates in the Udzungwa Mountains Using Systematic Distance Sampling
Extra‐pair paternity confirmed in wild white‐handed gibbons
Knowledge of the genetic mating system of animal species is essential for our understanding of the evolution of social systems and individual reproductive strategies. In recent years, genetic methods have uncovered an unexpected diversity of paternal genetic contributions across diverse animal social mating systems, but particularly in pair-living species. In most pair-living birds, for example, genetic and behavioral observations have confirmed …
Social Tolerance in Wild Female Crested Macaques ( Macaca nigra) in Tangkoko‐Batuangus Nature Reserve, Sulawesi, Indonesia
In primates, females typically drive the evolution of the social system and present a wide diversity of social structures. To understand this diversity, it is necessary to document the consistency and/or flexibility of female social structures across and within species, contexts, and environments. Macaques ( Macaca sp.) are an ideal taxon for such comparative study, showing both consistency and variation in their social relations. Their social st…
Female ovarian cycle phase affects the timing of male sexual activity in free‐ranging Barbary macaques ( Macaca sylvanus ) of Gibraltar
Although all macaques have a multimale multifemale mating system, the degree of promiscuity shown by the Barbary macaque is considered to be extreme in terms of both mating frequency and number of mating partners. How mating activity is distributed throughout the female menstrual cycle and whether or not copulations are concentrated around the fertile phase as in other members of the genus is, however, not known. To examine this, we collected dat…
Acoustic Niches of Siberut Primates
Female sexual swelling size, timing of ovulation, and male behavior in wild West African chimpanzees
Hormonal correlates of reproductive seasonality in wild female Hanuman langurs (Presbytis entellus)
To date, it is not known whether the seasonal occurrence of sexual behavior and mating in free-ranging Hanuman langurs at Ramnagar, Nepal, is correlated with seasonal changes in female ovarian function, and, if so, which factor(s) triggers the onset of the reproductive period. Using noninvasive fecal hormone analysis in combination with behavioral observations, this study was carried out to: 1) investigate and characterize seasonal patterns of ov…
