摘要:

为了探讨红外相机技术、网捕法、固定距离样线法和固定半径样点法对森林鸟类多样性调查的有效性和实用性, 我们于2011-2016年, 用这几种方法调查了广东南岭国家级自然保护区和车八岭国家级自然保护区的鸟类多样性。在南岭, 固定距离样线法和固定半径样点法记录鸟类222种, 网捕鸟类43种, 红外相机拍到鸟类47种; 其中1种鸟仅网捕到, 6种鸟仅被红外相机拍到, 164种鸟仅被固定距离样线法和固定半径样点法记录到。在车八岭, 固定距离样线法和固定半径样点法记录鸟类109种, 网捕鸟类42种, 红外相机拍到鸟类27种, 其中9种鸟仅网捕到, 3种鸟仅被红外相机拍到, 97种鸟仅被固定距离样线法和固定半径样点法记录到。随着鸟类的体重、体长、翅长和跗蹠增加, 网捕到的鸟类个体数量减少, 鸟类身体大小与网捕到的鸟类数量呈显著负相关; 而红外相机拍到的鸟类数量随鸟类的身体大小增大而增加, 并且呈显著的正相关。本文的结果显示, 网捕法和红外相机技术针对不同类群的鸟类调查效力不同, 但都是固定距离样线法和固定半径样点法的有效补充。建议今后开展森林鸟类多样性调查与监测时, 尽量采用多种研究方法相结合, 以求达到最优的效果。

Abstract:

To compare the effectiveness of camera trapping to more common mist netting, fixed-distance line transect, and fixed-radius point count methods of forest birds, we surveyed bird species diversity at Nanling National Nature Reserve and Chebaling National Nature Reserve, Guangdong, China from 2011 to 2016. At Nanling, 222 bird species were recorded by fixed-distance line transect and fixed-radius point count methods, 43 bird species were captured by mist netting and 47 bird species were trapped by cameras. One species was captured only by mist netting, six species only by camera-trapping, and 164 species only by fixed-distance line transect and fixed-radius point count methods. At Chebaling, 109 bird species were recorded by fixed-distance line transect and fixed-radius point count methods, 42 by mist nets and 27 by cameras. Nine species were recorded only by mist netting, three only by camera-trapping, and 97 only by fixed-distance line transect and fixed-radius point count methods. At both sites, the number of birds captured by mist netting was negatively correlated with increasing body size, whether measured as body weight, body length, wing length, or tarsus length. By contrast, the number of birds photographed by camera traps was positively correlated with the same measures of body size. These results show that bird surveys using different methods may yield different results and that method should be selected to suit the body size of the target bird species. In surveying bird diversity of a wide range of body sizes, mist netting and camera trapping together would be complimentary methods. Our results suggest that a combination of research methods may be necessary to obtain reliable avian diversity estimates.
