Abstract

Abstract. The jaguar (Panthera onca) is considered a keystone species for neotropical ecosystems. Jaguar records in natural protected areas (NPAs) are important to manage and maintain the long-term occupancy of the species in a region. The objectives of this study are to report the first jaguar records in the Sierra de Quila, Jalisco, Mexico, and to report observations of potential prey items. Between February 2018 and January 2019, 24 camera traps were placed for 180 days during 3 seasons, with a total capture effort of 3216 trap nights. Four hundred and two independent records were obtained from 17 species of wild mammals and 3 domestic species. In February, 2 photographs of a jaguar were recorded at a single sampling point in the Sierra de Quila Flora and Fauna Protection Area. They correspond to the same individual, presumably an adult male. Subsequently, in July, a photograph of a jaguar was recorded at another sampling point. These records represent a 69-km extension of the known jaguar distribution, to the center of Jalisco, and increase the number of mammal species known for this NPA.

美洲虎(Panthera onca)和潜在猎物物种在墨西哥哈利斯科州奎拉山脉的首次记录

摘要美洲虎(Panthera onca)被认为是新热带生态系统的关键物种。在自然保护区(NPAs)记录美洲虎对管理和维持该物种在一个地区的长期占用具有重要意义。本研究的目的是报告在墨西哥哈利斯科州塞拉德奎拉的第一次美洲虎记录，并报告对潜在猎物的观察结果。在2018年2月至2019年1月期间，在三个季节中放置了24个相机陷阱，持续180天，总捕获次数为3216个陷阱夜。获得了17种野生哺乳动物和3种家养哺乳动物的242份独立记录。今年2月，在塞拉德奎拉动植物保护区的一个采样点记录了两张美洲虎的照片。它们对应于同一个个体，可能是一个成年男性。随后，在7月，在另一个采样点记录了一张美洲虎的照片。这些记录代表了已知的美洲虎分布向哈利斯科州中心延伸了69公里，并增加了该国家保护区已知的哺乳动物物种的数量。
