Metadata for Jaguarundi Status and Distribution in Texas and Northeastern Mexico

The jaguarundi (Puma yagouaroundi) is a small felid with a historical range from central Argentina through southern Texas. Information on the current distribution of this reclusive species is needed to inform recovery strategies in the United States (U.S.) where its last record was in 1986 in Texas. From 2003 to 2021, we conducted camera-trap surveys across southern Texas and northern Tamaulipas, México to survey for medium-sized wild cats (i.e., ocelots [Leopardus pardalis], bobcats [Lynx rufus], and jaguarundi). After 350,366 trap nights at 685 camera sites, we did not detect jaguarundis at 16 properties or along two highways (1,050 km2) in Texas. However, we recorded 126 jaguarundi photographic detections in 15,784 trap nights on two properties (125.3 km2) in the northern Sierra of Tamaulipas, Tamaulipas, México. On these properties, latency to detection was 72 trap nights, with a 0.05 probability of detection per day and 0.73 photographic event rate every 100 trap nights. Due to a l...

美洲虎猫（Puma yagouaroundi）是一种小型猫科动物，历史分布范围涵盖阿根廷中部至得克萨斯州南部。当前亟需获取这一行踪隐秘物种的现存分布数据，以支撑美国境内的种群恢复策略制定——美国境内最后一次该物种的观测记录为1986年在得克萨斯州。2003年至2021年间，我们在得克萨斯州南部及墨西哥塔毛利帕斯州北部开展了相机陷阱调查（camera-trap survey），以监测中型野生猫科动物类群，包括虎猫（Leopardus pardalis）、短尾猫（Lynx rufus）及美洲虎猫。在685个相机监测点位累计完成350366个相机陷阱夜后，我们在得克萨斯州的16处地块及沿两条公路布设的1050平方公里调查区域内均未监测到美洲虎猫。然而在墨西哥塔毛利帕斯州北部塞拉地区的两处地块（总面积125.3平方公里）中，我们在15784个相机陷阱夜内记录到126次美洲虎猫的拍摄捕获事件。在该两处地块中，首次探测潜伏期为72个陷阱夜，单日探测概率为0.05，每100个陷阱夜的拍摄事件发生率为0.73。由于...
