Aims: The Bawangling Area of the National Park of Hainan Tropical Rainforest belongs to biodiversity hotspot area of China, and its natural environment is ideal for amphibians. However, the diversity of anuran amphibians in the area is still unknown. Here we investigated the diversity of anurans in the region and explored the relationships between anuran calling and the environment.

Methods: The emerging bio-acoustic methods were applied in this study. Five areas with different habitats were selected in the Bawangling Area of the National Park. In each area, three recorders were deployed to consistently collect sound data in June, August to September, December 2021 and January to March 2022, respectively (over 15 days in each period).

Results: In total, we recorded 17 frog species belonging to 11 genera and 6 families. Four seasons had different species composition among which the least species appeared in winter (December). Species composition also varied in different areas among which Feilie had most species. Of these 17 species, 12 species called only at night, while 3 species called mainly at night and occasionally during the day, and 2 species called actively throughout the day. Moreover, rainfall had different effects on species in different habitats. Rainfall did not affect the calling activity of Amolops torrentis and Hylarana guentheri inhabiting permanent water, as well as Microhyla fissipes inhabiting diverse environemnts. The calling activity of Limnonectes fragilisdwelling in shallow streams and Leptobrachium hainanense living on the ground was higher on raining days.

Conclusions: In sum, season, day and night, location and rainfall may affect the diversity and calling activity of frogs in Bawangling region. This study not only enriches the ecological data of amphibians in Hainan tropical rainforest, but also contributes to the ecological conservation and assessment of wildlife in the Bawangling Area of the Hainan Tropical Rainforest National Park.
