Juveniles of Japanese macaques
Positional Behavior of Primates
Sorry, now constructing. Index, only.
| Background and aim of my study |
*Positional behavior is most fundamental behavior for animals. *Primates: various locomotion and posture, various morphology *Primates: slow speed of development *Development of locomotion and posture: related to cognition, control system, ecology, social structure, and so on. *But field study of positional behavior is not many. |
| Positional behavior and its development of Japanese macaques |
*Genus Macaca is most widely spread in non-human Primates. *Japanese macaques have the intermediate positional behavior between terrestrial pig-tailed macaques and arboreal long-tailed macaques. *Japanese macaque is the "quadruped". They hardly suspend. *But suspensory behavior is very important for infants to develop independent locomotion. |
| Positional behavior and its development of patas monkeys |
*Patas monkey:the fastest runner in Primates *Patas monkey has long limbs and lives in the Savanna. *Long limbs for...:Temperature regulation?,Running away?,Foraging? *Various terrestrial positional behaviours. *Unique locomotor types. *Why the speed of development is high? *How do infants and juveniles survive in the Savanna? |
| Development of positional behavior of chimpanzees |
*Are there any characteristics of the development of locomotion differing from cercopithecoids? *Origin of bipedal walking of human |
| Inter-specific comparison | *Relation among development of locomotion,morphology, cognition, and control system. |
| Development of positional behavior, ecological and social factors |
*Relation to mother's care *Relation to environment |
