  • Title
    Male Influx, Infanticide, and Female Transfer inMacaca radiata radiata
    Type
    Report
    Description
    In bonnet macaques, males usually disperse between groups and females remain philopatric, but researchers have reported female transfer. We reporta rare case of male influx during the mating season in our bonnet macaquestudy group in the Anaimalai Hills. The density of bonnet macaques in thestudy region was unusually high. The study group had a single, crippled adultmale with a long tenure and 5 adult females. During the mating season, adult females approached and mated with outgroup males, and then several malesentered the group. The adult male left the group without any resistance. Theincoming males mated with 3 receptive females, forcibly mated with 2 lactating females, and attacked and killed 2 infants. During the influx, 2 outgroup females joined the group. The data suggest that male influxes providean opportunity for infanticide and female transfer, which can have importantfitness consequences even in species in which they rarely occur.

  • Title
    Distribution, abundance, group size and demography of dark-bellied bonnet macaque Macaca radiata radiata in Karnataka, South India
    Type
    Report
    Description
    We carried out an extensive survey on bonnet macaques in the south Indian state of Karnataka over a period of five years. We travelled 9697 km covering all districts and recorded the distribution, encounter rate and demographic features of bonnet macaque groups on roadsides and villages, temples and several different forest types, and walked1736 km in selected Protected Areas and Reserve Forests. Bonnet macaque groups were encountered ata rate of 2.11 groups/ 100 km in a road survey. Encounter rates were high in the districts of Chamarajanagar, Shimoga, Bangalore, Kolar, Kodagu and Mysore. Encounter rates were higher in wet evergreen forests than in deciduous forests. Mean group size was highest in human habitations followed by deciduous forests, roadsides and evergreen forests. The groups in highly provisioned places had the highest size compared to medium or low degree of provisioning. Age–sex ratios were observed to be the same in all habitat types. We propose that large-scale surveys of the present type provide baseline data for long-term management and conservation of a species.
