[Objectives] The Common Palm Civet Paradoxurus hermaphroditus has been recently listed as a Class-Ⅱ National Key Protected Wildlife in China, assessed as an “Endangered (EN)” species by China’s Red List of Biodiversity. Currently, there is still a lack of research on its field ecology in China. The objectives of this study are to improve the understanding of the grouping pattern and daily activity rhythms of the Common Palm Civets, and investigate the effects of elevation, human disturbances and seasons on their activities in Jianfengling, Hainan, China. [Methods] From November 2020 to October 2022, the camera trapping method was used to study the activity pattern of the Common Palm Civet in Jianfengling, and 150 infrared cameras were deployed in areas of high level of animal activity, with cameras spaced at intervals of 500 m or more. Infrared camera data were collected every 4 months. Kernel density estimation was used to plot daily activity rhythms of the species in dry and rainy seasons, and seasonal differences in activity rhythms were analyzed by comparing the overlapping degree of daily activity curves of Common Palm Civets in the dry and rainy seasons. Their activity intensity was expressed as the ratio of the number of valid detections per camera site to the total number of valid detections. The Mann-Whitney U test was used to analyze inter-regional and seasonal differences in elevations at the activity sites of Common Palm Civets, and the effects of human disturbance on their activity intensity as well as its seasonal difference. Generalized linear model was used to analyze the effects of elevation and human disturbances on their activity. [Results] A total of 637 independent valid photos of the Common Palm Civets were obtained, 376 in the dry season and 261 in the rainy season. The results showed that Common Palm Civets in Jianfengling were predominantly solitary (98.90%), and occasionally in small groups of 2﹣4 ind. Their activities were significantly affected by elevation and human interferences, being correlated positively with elevation and negatively with interference intensities (Fig. 3). The elevations of their activity sites did not differ significantly between the dry and wet seasons, but there were clear seasonal differences in the effects of human disturbance on their activities. Their activity intensities were significantly greater in the dry seasons than in the rainy seasons in areas with low human disturbances (P < 0.05), but no obvious difference between the dry and rainy seasons in areas with high human disturbances was found. Their activity intensities in the dry season were less in the high interference area than that in the low interference area (P < 0.05), but in the rainy season there was no regional difference in their activity intensities (Fig. 2). The activity time of Common Palm Civets was centered 19:00﹣6:00 every day, and there was a peak of activity in the dawn and dusk, showing typical nocturnal behavior, with occasional daytime activity (1.73%). [Conclusion] The Common Palm Civet in Jianfengling was a typical nocturnal animal and mainly lived solitary. Their activity intensities were correlated positively with elevation and negatively with interference intensities.
