    Primates 43:41-9. 2002
    ..Considering the intrinsic rate of natural increase of lice, monkeys need to be groomed almost every day. This suggests that Japanese macaques need grooming partners and form social bonds with others for everyday grooming...
  2. ncbi request reprint Leaf-grooming by a wild chimpanzee in Mahale
    Koichiro Zamma
    Laboratory of Human Evolution Studies, Department of Zoology, Graduate School of Science, Kyoto University, Kitashirakawa Oiwake cho, Sakyo, Japan
    Primates 43:87-90. 2002
    ..I present this observation as further evidence of the "squashing ectoparasites" hypothesis for leaf-grooming...

    Goro Hanya
    Primate Research Institute, Kyoto University, Inuyama, Aichi, 484 8506, Japan
    Primates 49:116-25. 2008
    ..The present results indicate that the female social relationships of Japanese macaques are robust and do not change according to changes in the current environment...
  4. ncbi request reprint Demography, female life history, and reproductive profiles among the chimpanzees of Mahale
    Toshisada Nishida
    Department of Zoology, Graduate School of Science, Kyoto University, Sakyo, Kyoto, Japan
    Am J Primatol 59:99-121. 2003
    ..The extent of female transfer, which is a rule in chimpanzees, is influenced by the size and composition of the unit group and size of the overall local community...

    Goro Hanya
    Department of Zoology, Graduate School of Science, Kyoto University, Kyoto, Japan
    Am J Primatol 60:43-56. 2003
    ..This method is applicable to other species as long as at least one group can be followed, because it satisfies the fundamental assumptions of point census, and the detectability does not seem to be biased by troop or topography...

    Takahisa Matsusaka
    Laboratory of Human Evolution Studies, Graduate School of Science, Kyoto University, Sakyo ku, Kyoto 606 8502, Japan
    Primates 47:113-22. 2006
    ..We should note here that such behaviors that lack obvious benefits or necessity can be prevalent in a group...

    Am J Primatol 66:245-62. 2005
    ..On the other hand, in the naturally regenerated forest, fruit production and herb availability were high (probably because of the enhanced light conditions after logging), and the density of macaques was as high as in the primary forest...
