摘要: 鸡形目鸟类是全球受胁程度最高的动物类群之一。中国横断山脉地区的高山生态系统条件恶劣且气候严苛,分布着多样性极高的鸡形目鸟类,了解其群落结构时空动态对于群落保护至关重要。以横断山脉东缘的四川卧龙国家级自然保护区为研究区域,于2019年5月至2021年1月在海拔3 500~4 800 m的高山生态系统建立109个红外相机位点对鸡形目鸟类进行监测,共覆盖72个网格(1 km×1 km),累计监测33 759个相机日。结果表明,(1)保护区高山生态系统鸡形目鸟类群落由9个物种组成,特有种和国家重点保护物种比例高,具有重要保护价值。绿尾虹雉(Lophophorus lhuysii)、雪鹑(Lerwa lerwa)和血雉(Ithaginis cruentus)相对多度较高,是群落中的数量优势种。(2)鸡形目鸟类群落结构时空动态明显。物种丰富度和总相对多度在灌丛生境和3 500~4 000 m海拔段最高,繁殖季(4-7月)相对多度远高于非繁殖季(8月-翌年3月)。(3)不同物种有不同生境选择偏好,雪鹑显著选择上位坡;血雉显著选择低海拔和灌丛生境,回避流石滩生境;藏雪鸡(Tetraogallus tibetanus)显著选择高海拔和流石滩生境,拒绝灌丛生境;绿尾虹雉未表现出显著选择性,可利用各类生境资源。(4)保护区梯子沟和银厂沟是鸡形目鸟类重要分布区。位于梯子沟和银厂沟的网格监测到较高的物种丰富度和相对多度。基于研究结果,建议将绿尾虹雉设为重要保护对象,并重点关注对3 500~4 000 m海拔段灌丛生境的保护和管理;将梯子沟和银厂沟作为鸡形目鸟类优先保护区域,促进区域高山生态系统鸡形目鸟类群落的整体保护。

Abstract: Order Galliformes is one of the most threatened animal taxa worldwide. Despite the harsh environment and climate conditions, the alpine ecosystems of Hengduan Mountains support rich diversity of Galliformes. Understanding the spatio-temporal dynamics of Galliformes in the alpine ecosystems and species' habitat selection is crucial for effective conservation. In this study, 109 infrared cameras were positioned at altitude from 3 500 m to 4 800 m, covering 72 grids (1 km×1 km) to monitor alpine Galliformes species in Wolong National Nature Reserve, Sichuan Province from May of 2019 to January of 2021. The monitoring involved effort of a total of 33 759 trap days. The results show that:(1) There were 9 Galliform species in alpine ecosystems, with high proportion of endemic and protected species, and Chinese monal (Lophophorus lhuysii), snow partridge (Lerwa lerwa) and blood pheasant (Ithaginis cruentus) dominated this community with higher relative abundances. (2) Both species richness and relative abundance of alpine Galliformes were greater in shrubs with the altitudinal range from 3 500 m to 4 000 m, while relative abundance of all the species were much higher during breeding seasons (from April to July) than during non-breeding seasons (from August to March). (3) Snow partridge select preferentially habitats at upper slopes, blood pheasant prefer shrubs with lower altitudes and avoided tundra, and Tibetan snowcock (Tetraogallus tibetanus) prefer higher altitude and tundra habitats while avoiding shrubs, while Chinese monal have no significant habitat preference. (4) Species richness and relative abundance were the highest in the monitored grids in Tizigou and Yinchanggou, indicating these areas are important areas for Galliformes species' distribution throughout the Wolong National Nature Reserve. Given remarkable conservation value of alpine Galliformes in Wolong National Nature Reserve. It is advised that:(1) to consider Chinese monal as a key conservation species in alpine ecosystems and focus on the protective management of shrubs at an elevation of 3 500-4 000 m, (2) to treat Tizigou and Yinchanggou as priority areas for regional Galliformes conservation.
