Influence of provisioning on primate behavior and primate studies.

After World War II, primate studies began on Japanese macaques and artificial provisioning facilitated short-distance observation. During these early stages of primate field research, this method allowed for individual recognition and long-term studies whereby individual and social behaviors could be described in detail and, ultimately, social structure. Owing primarily to provisioning, monkeys and apes were able to innovate some cultural behaviors. However, provisioning influences the behavior of animals. Artificially fed primate populations in Japan grew rapidly and social relationships among individuals changed. After the 1980s, scientific reports tended to not mention the incidence of provisioning in descriptions of the environment. Such omissions could inadvertently lead to misleading interpretations of the data. Therefore, authors must describe the provisioning situation as an important element of the environment. Even in the early stages of the primate studies, it should have been noted that provisioning was an experimental method and was partly an artificial living condition applied to wild populations of animals, which could have both positive and negative outcomes. In this paper I defined the terms wild, provisioning, free-ranging and habituation in appropriate words. [ABSTRACT FROM AUTHOR]
