| 其他摘要 | Biodiversity conservation is more and more discussed at large spatial and temporal scales even at global scale, its huge value and the fast degrading situation has been recognized by more and more people. We need make quick and effective conservation policy for those areas, which needs urgent protection, like Mengsong. It was suggested the sounds produced by singing animals have advantages to be an objective biodiversity indicator, which can be assessed fast in big scale of space and time and might can help solve those problems mentioned above. We tested Sueur et al.'s (2008) new bioacoustic method in natural habitats for its effects on indicating bird diversity and habitats differences, for which is based on the singing communities built in the lab. After several statistical tests on a new method, we found that in our experimental site, Mengsong, Yunnan, China, the H index, which describes community sound diversity has a significant correlation with community bird diversity, but only in closed canopy forests. It suggests the sound H index can help estimate bird richness or even α biodiversity, but only in forest habitats that are original and protected well. Also, the D index, which measures the dissimilarity of two sound files, is correlated with bird dissimilarity and can differentiate different habitats, also only in closed canopy forests in continuous habitats. In short, the sound D index can differentiate natural habitats differences, but only in hugely different habitats, like between forest and non-forest, and might can detect the bird diversity dissimilarity in closed and continuous forest. Anyway, wider and deeper bioacoustic researches for soundscape ecology are needed to build mature bioacoustic biodiversity census method, discover more masked functions of community sounds, and describe the community ecological characters. Also more fostering discussions and collaborations are needed to build the fundamental framework and disciplines, pushing the bioacoustic research and soundscape ecology to a mature stage. |
