College of Life Science, Northwest University, Xi an, China
Am J Primatol 70:634-41. 2008..The linear dominance relationship among OMUs in the Sichuan snub-nosed monkeys may have evolved as a result of competition for preferred food trees... - Successive aggression: another pattern of polyadic aggressive interactions in a captive group of Japanese macaquesKunio Watanabe
Primate Research Institute, Kyoto University, Inuyama, Japan
Am J Primatol 70:349-55. 2008..Successive aggression may function to establish and maintain dominance relationships among matrilineal groups through repeated confirmations... - Habitual hot-spring bathing by a group of Japanese macaques (Macaca fuscata) in their natural habitatPeng Zhang

Am J Primatol 69:1425-30. 2007..We compared hot-spring bathing with other thermoregulatory behaviors in various primate populations... - Extra-large cluster formation by Japanese macaques (Macaca fuscata) on Shodoshima Island, central Japan, and related factorsPeng Zhang
Field Research Centre, Primate Research Institute, Kyoto University, Inuyama, Aichi, Japan
Am J Primatol 69:1119-30. 2007..Inter-group comparisons suggest that the social structure of Japanese macaques might be highly plastic, and that Shodoshima monkeys have less despotic, more tolerant social relations than typically reported for this species... - Preliminary study on eye colour in Japanese macaques (Macaca fuscata) in their natural habitatPeng Zhang
Primate Research Institute, Kyoto University, Inuyama, Aichi 484 8506, Japan

Primates 47:374-82. 2006..The OMU in the study area were smaller than those in Shennongjia area. The factors influencing the size of these OMU and the entire group are discussed... 
Free-ranging macaque mothers exaggerate tool-using behavior when observed by offspringNobuo Masataka
Primate Research Institute, Kyoto University, Inuyama, Japan
PLoS ONE 4:e4768. 2009..We interpret this as evidence for the possibility that they exaggerate their action in tool-using so as to facilitate the learning of the action by their own infants...- Diet and activity budget of Rhinopithecus roxellana in the Qinling Mountains, ChinaSongtao Guo

Primates 48:268-76. 2007..R. roxellana spent more time moving in autumn, when the quality of the food might be highest, and least time moving in winter when the food quality might be lowest. Thus, this type of monkey has a passive foraging strategy... - Impact of male takeover on intra-unit sexual interactions and subsequent interbirth interval in wild Rhinopithecus roxellanaDapeng Zhao

Equipe d Ethologie des Primates, Institut Pluridisciplinaire Hubert Curier, Department Ecologie, Physiologie et Ethologie, Strasbourg, France
Am J Primatol 69:821-8. 2007..This report should contribute to a better understanding of how social features may constrain the long-term diffusion of feeding innovations in free-ranging primate groups... - First wild evidence of neonate nipple preference and maternal cradling laterality in Old World monkeys: a preliminary study from Rhinopithecus roxellanaDapeng Zhao
