摘要:

海南热带雨林国家公园霸王岭片区属于我国生物多样性热点地区, 其自然环境非常适合两栖类生存, 但该区域的无尾两栖类多样性情况尚不清楚。本研究利用新兴的生物声学方法, 调查该地区无尾两栖动物的多样性, 并了解蛙类鸣叫与环境的关系。我们在国家公园霸王岭片区选择5个生境不同的区域, 每个区域设置一条样线, 每条样线上布设3台录音设备, 于2021年6月、8‒9月和12月以及2022年1‒3月分别收集至少半个月的声音数据。本次调查共记录到蛙类17种, 隶属6科11属。四季的物种组成存在差异, 其中冬季(12月)出现的物种最少。不同区域的物种组成也存在差异, 其中飞列地区发现的物种最多。记录到的17种蛙中, 有12种仅在夜晚鸣叫, 有3种主要在夜晚鸣叫, 偶尔也在白天鸣叫, 有2种全天都活跃鸣叫。不同生境蛙类对降雨的响应也存在差异。永久水体中的小湍蛙(Amolops torrentis)和沼水蛙(Hylarana guentheri), 以及栖息环境多样的饰纹姬蛙(Microhyla fissipes), 鸣叫活性不受降雨影响, 但浅水溪流中的脆皮大头蛙(Limnonectes fragilis)和地面上的海南拟髭蟾(Leptobrachium hainanense)鸣叫活性在降雨日更高。综上, 季节、昼夜环境、地理位置和降雨的差异会影响霸王岭片区蛙类的多样性和鸣叫活性。本研究不仅丰富了海南热带雨林两栖类的生态资料, 也有助于海南热带雨林国家公园霸王岭片区野生动物的生态保护和评估。

Abstract

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.
