Abstract
The contents of studies of biology in high schools largely changed from the 2012 fiscal year according to the change of the course of study. The results of field studies of non-human primates had become to contribute basic or more advanced studies of biology in high schools by these changes. This paper describes how the results of field studies of non-human primates can contribute to studies of biology in high schools. Topics such as primates as keystone species and interspecific relationships among primates could be helpful for studying contents in sections as “Biodiversity of Creatures and Ecosystems” in “Basic Biology” and “Ecology and Environments” in “Advanced Biology.” Supplementary books in accordance with text books are very useful for such attempt and cooperation between teaching stuffs of high schools and universities is necessary to make such supplementary books.
