Table 1. Definitions of 22 behavioral variables.

Variable Description
prop time spent active Proportion of scan samples out of all scan samples not spent resting or self-grooming (at one minute interval)
prop time spent outside group Proportion of scan samples in which animal was not in the center or periphery of the group; scans were taken twice per focal protocol: after 30 minutes and after 60 minutes
rate self-grooming Hourly rate of self-grooming bouts (bouts were considered distinct if separated by > 2 seconds)
rate self-scratching Hourly rate of self-scratching bouts (bouts were considered distinct if separated by > 2 seconds)
rate yawning Hourly rate of yawns
rate status display Hourly rate of loud call vocalization, a signal indicating dominance status [39]
prop time spent grooming Proportion of scan samples out of all scan samples spent grooming other individuals (at one minute interval)
diversity grooming partners Diversity index of adult females grooming was received from and given to; assessed from scan samples at one minute intervals
diversity grooming given Diversity index of adult females grooming was given to; assessed from scan samples at one minute interval
number of female neighbors Absolute number of adult female neighbors within five body lengths; assessed at scans every five minutes
diversity female neighbors (close) Diversity index of adult females in close proximity (within one body length or in body contact); assessed during scans every five minutes
diversity female neighbors (far) Diversity index of adult females in proximity (within five body lengths, but further than one body length); assessed during scans every five minutes
diversity male neighbors (close) Diversity index of adult males in close proximity (within one body length or in body contact); assessed during scans every five minutes
diversity male neighbors (far) Diversity index of adult males in proximity (within five body lengths, but further than one body length); assessed during scans every five minutes
rate approaching males Hourly rate of approaching adult males within a range of five body lengths
rate approaching females Hourly rate of approaching adult females within a range of five body lengths
rate affiliation towards males Hourly rate of affiliative behavior (lip smack, mount, genital touch, friendly touch, play) directed at adult males
rate affiliation towards non-males Hourly rate of affiliative behavior (lip smack, mount, genital touch, friendly touch, play) directed at individuals other than adult males
rate threats towards males Hourly rate of threats directed at adult males
rate threats towards non-males Hourly rate of threats directed at individuals other than adult males
rate aggression towards males Hourly rate of overt aggression (bite, chase, hit) given to adult males
rate aggression towards non-males Hourly rate of overt aggression (bite, chase, hit) given to individuals other than adult males
