摘要: The average frequencies of communicative behavior, social and encounters (inter-individual proximity within three meters) per hour for a monkey were obtained in their natural habitat by tracing several adult males females Japanese troop living the Koshima islet. spatial distribution patterns density members expanse at any moment investigated femals. Frequency distributions monkeys found five 10 meters compared with Poisson distribution. interactions distinctly low, except between mothers offspring. was very low. Both aggressive behavior inter-individual (within low when foraging food. An avoiding mechanism among plays an important role maintaining structure these monkeys. This works two ways: each individual does not approach others too closely; is all times.
