Predictive analysis of suitable habitats and their overlap for the Blyth's kingfisher and the Pied falconet in China

摘要：

研究同域物种的分布格局和重叠情况，对于生物多样性保护、区域整合管理及开发利用具有重要意义.斑头大翠鸟(Alcedo hercules)和白腿小隼(Microhieraz melanoleucos)均是东洋界物种、国家二级重点保护野生动物，又是观鸟界的明星鸟种，然而关于它们分布格局的研究尚显匮乏，制约了保护工作及观鸟产业的发展.通过实地调查结合查阅历史数据收集两个物种的分布位点，利用Biomod2模型预测两者在中国的潜在适生区分布，进一步探讨了影响分布的环境因子并分析重叠情况.结果显示:1)共收集斑头大翠鸟分布位点35个，白腿小隼34个;斑头大翠鸟的高适生区面积为286180 km,主要分布于广东、广西、福建及江西4省:白腿小隼的高适生区面积为38955 km²,主要分布于江西、福建、浙江及广东4省.2)影响斑头大翠鸟分布的主要环境因子是年降水量(Bio12,贡献率为57.2%).而影响白腿小隼分布的主要环境因子是最冷季降水量(Bio19.贡献率为54.8%).3)两者生态位重叠度较高(I=0.8),适生区的重叠区域主要分布在江西和福建两省.研究表明江西和福建两省应加强这两个物种的保护和监测工作，更具有围绕这两个物种打造观鸟产业链的区域优势,研究结果能够为实现珍稀濒危鸟类斑头大翠鸟和白腿小隼的有效保护，以及围绕它们打造的观鸟旅游产业的可持续发展提供理论指导

Investigating the distribution paterns and overlaps of sympatric species is of crucial significance for biodiversity conservation, integrated regional management, and sustainable development and utilization. The Blyth's kingfisher（Alcedo hercules) and the Pied falconet(Microhierar melanoleucos) are both species native to the Oriental realm, which are protected as sccond-class wildlife by the state and are star bird species in the bird-watching community. However, the lack of research on their distribution patterns remains scarce hampers the advancement of conservation efforts and the development of the bird-watching industry. This study collected distribution sites for both species through field surveys and historical data review, uti-lized the Biomod2 model to predict their potential suitable habitats in China, and further explored the environmental factors infuencing their distributions and analyzed their overlap. The results indicated that：1) A total of 35 distribution sites for the Blyth's kingfisher and 34 distribution sites for the Pied falconet were colected in the study. The high-suitability habitats for the Blyth's kingfisher cover an area of 286 180 km², mainly distributed in Guangdong, Guangxi, Fujian, and Jiangxi provinces; and the high-suitability habitats for the Pied falconet cover an area of 38 955 km², mainly distributed in Jiangxi, Fujian, Zhejiang.and Guangdong Provinces. 2) The main environmental factor infuencing the distribution of the Blyths kingfisher is annual precipitation(Biol2, with a contribution rate of 57. 2%), while the main environmental factor influencing the distribution of the Pied falconet is precipitation of the coldest quarter(Bio19, with a contribution rate of 54. 8%). 3) The niche overlap between the two species is high(I=0.8). with the overlapping suitable habitats mainly distributed in Jangxi and Fujian provinces. The results indicate that Jiangxi and Fujian provinces should strengthen the conservation and monitoring of these two species and have a regional advantage in developing a bird-watching industry chain centered around them. The research findings provide the-oretical guidance for the effective conservation of the endangered Blyths kingfisher and Pied falconet and the sustainable devel-opment of the bird-watching tourism industry built around them.
