Abstract:
The Medog in southeastern Tibet is home to a diverse range of wild animals. However, research on these mammals\' species directories, distribution, and conservation status remains insufficient, despite their crucial role in maintaining ecological balance. The study carried out a camera-trapping survey to assess mammal biodiversity and the significance of mammal protection in their natural habitats in Gedang, Medog. Future directions and application prospects of the study for wildlife conservation in the southeastern Tibetan mountains were also discussed. The survey, spanning from April 2023 to May 2024, with 19,754 camera trap days, revealed 25 mammalian species across five orders and 14 families. Among these, four classified as Endangered, five as Vulnerable, two as Near Threatened on the IUCN Red List, nine were categorized as Critically Endangered or Endangered on the Red List of China\'s Vertebrates, and seven were China\'s national first-class key protected wildlife. The order Carnivora exhibited the highest diversity, comprising 12 species. Furthermore, the study filled the knowledge gap regarding the underrepresentation of Gongshan muntjac Muntiacus gongshanensis in IUCN and provided new insights into the recorded coexistence of the Himalayan red panda Ailurus fulgens and Chinese red panda Ailurus styani along the Yarlung Zangbo River for the first time, and also documented new upper elevation limits for four large to medium-sized species. Regarding the relative abundance indices (RAI) captured by camera traps, the most prevalent species identified was the White-cheeked macaque Macaca leucogenys, followed by the Gongshan muntjac and Himalayan serow Capricornis thar. The monitoring also captured a number of domestic dogs and livestock, as well as human disturbances. These findings underscore the importance of conserving these mammals and emphasize the need for conservation efforts to protect their habitats and reduce human activities that threaten their survival, thereby maintaining the ecological balance of the region. Additionally, the research highlighted Gedang\'s significance to global conservation efforts for mammalian diversity, providing essential data for effective wildlife conservation strategies.
摘要:
西藏东南部的墨脱是各种各样的野生动物的家园。然而,研究这些哺乳动物的物种目录,分布,保护状况仍然不足,尽管它们在维持生态平衡方面发挥了关键作用。这项研究进行了一项相机诱捕调查,以评估哺乳动物的生物多样性以及在格当的自然栖息地中保护哺乳动物的重要性,墨狗还讨论了藏东南山区野生动物保护研究的未来方向和应用前景。调查,从2023年4月到2024年5月,有19,754个相机陷阱天,揭示了5个目14科的25种哺乳动物。其中,四个被列为濒危物种,五个是脆弱的,两个被IUCN红色名录威胁到了,有9人在中国脊椎动物红色名录上被列为极度濒危或濒危,七种是中国国家一级重点保护野生动物。食肉目表现出最高的多样性,包括12种。此外,这项研究填补了有关IUCN中贡山muntjacMuntiacusgongshanensis代表性不足的知识空白,并首次为雅鲁藏布江沿岸的喜马拉雅红熊猫Ailurusfulgens和中国红熊猫Ailurusstyani的共存记录提供了新的见解,并记录了四个大中型物种的新海拔上限。关于相机陷阱捕获的相对丰度指数(RAI),确定的最普遍的物种是白颊猕猴,其次是贡山蒙太奇和喜马拉雅山塞罗·卡比尼斯塔尔。监测还捕获了一些家犬和牲畜,以及人类的干扰。这些发现强调了保护这些哺乳动物的重要性,并强调了保护其栖息地和减少威胁其生存的人类活动的必要性。从而维持该地区的生态平衡。此外,这项研究强调了Gedang\对全球哺乳动物多样性保护工作的重要性,为有效的野生动物保护策略提供必要的数据。
