摘要: The golden snub-nosed monkey (Rhinopithecus roxellana) has marked seasonal changes in facial color and reproductive activity. Quantitative measurement of color is the premise of studying color change, and it is also the first technical problem that must be solved to reveal the mechanism of color change. In this study, a digital camera was used to capture facial portraits and a standard color card was used to calibrate the photo colors. Then, the facial colors were digitized using Image J software. The reliability of photo digital measurement in the study of golden snub-nosed monkeys’facial colors was verified by measuring the facial colors with B/Y value. The results show that the digital photo measurement method can significantly distinguish the difference in individual facial color between birth season and mating season. This proves that the facial color is related to the season to some extent, and digital photography is a reliable method to evaluate the facial color change of golden snub-nosed monkeys.
