摘要

印度穿山甲(Manis crassicaudata)是巴基斯坦发现的唯一一种穿山甲目动物。本研究旨在比较2019-2022年期间巴基斯坦八个地区(开伯尔-普赫图赫瓦省四个地区和旁遮普省四个地区)印度穿山甲的死亡率和死亡原因。数据收集采用自行设计的调查问卷(n = 340)和社交媒体报告。大部分数据来自 Facebook(53%),其次是 Instagram(22%)、WhatsApp(17%)和 OLX(10%)。平均值和标准偏差的计算方法包括:地区杀戮(平均值±标准偏差为 15.25 ± 10.21)、季节杀戮(平均值±标准偏差为 30.50 ± 9.8)、月份杀戮(平均值±标准偏差为 10.38 ± 4.19)和地区杀戮(平均值±标准偏差为 40.7 ± 17.6)。开伯尔-普赫图赫瓦省的四个县记录到 179 头印度穿山甲被杀,而旁遮普省则有 59 头印度穿山甲被杀。据受访者称,33%的印度穿山甲死亡是由非法捕杀造成的,其次是人类居住区(17%)、农业耕作(13%)、螨虫和虱子(11%)、自然死亡(8%)、事故(7%)、神话传说(6%)和洪水(5%)。开伯尔-普赫图赫瓦邦和旁遮普邦的地区野生动物部门在 2019-2022 年期间逮捕了许多人(开伯尔-普赫图赫瓦邦 n = 83 人,旁遮普邦 n = 57 人)。查克瓦尔野生动物管理局处以最高罚款,即 20,000-60,000 卢比以及 1-4 个月的监禁。共发现 8 只死亡穿山甲,其中 6 只为雄性(75%),2 只为雌性(25%)。主成分分析(PCA)显示,PC 似乎受螨虫和扁虱 (MT)、神话、自然死亡 (NM) 和 "洪水 "的影响最大,因为它们的载荷很高。PC2 受非法贸易杀戮(KFIT)、事故和农业实践(AP)的影响较大,因为它们的负载荷很高。PC3 以 NM 和 AP 为主要变量,KFIT 也发挥了作用,但方向相反。PC4 显示了 NM(负)和洪水(正)的强烈影响。我们的结论是,非法捕杀印度穿山甲的现象非常严重。保护工作对于保护这些独特的濒危生物至关重要。

Drivers of Indian pangolin (Manis crassicaudata) mortality in Central and Western Pakistan
The Indian pangolin (Manis crassicaudata) is the only member of the order Pholidota found in Pakistan. The current study was designed to compare the mortality rate and causes of mortality of Indian pangolin from eight districts, i.e., four from Khyber Pakhtunkhwa and four from Punjab, Pakistan during 2019–2022. Data were collected by using self-designed questionnaires (n = 340) and social media reports. Most of the data were collected from Facebook 53 %, followed by Instagram (22 %), WhatsApp (17 %), and OLX (10 %). Mean and standard deviation were computed for district-wise killing (mean ± SD 15.25 ± 10.21), season-wise killing (mean ± SD 30.50 ± 9.8), month wise killing (mean ± SD 10.38 ± 4.19) and area wise killing (mean ± SD 40.7 ± 17.6). The killing of 179 Indian pangolins was recorded in four districts of Khyber Pakhtunkhwa, while in Punjab 59 Indian pangolins were killed. According to interviewees, 33 % of the mortality of Indian pangolin was caused by illegal killing followed by human settlement (17 %), agricultural practices (13 %), mites and ticks (11 %), natural mortality (8 %), accidents (7 %), myth (6 %), and floods (5 %). District wildlife departments of Khyber Pakhtunkhwa and Punjab arrested many people (KPK n = 83, Punjab n = 57) during 2019–2022. The highest fines were imposed by the Chakwal Wildlife Department, i.e., 20,000–60,000 PKR along with 1–4 months of imprisonment sentences. Eight dead pangolins were recovered among those six were male (75 %) and two were female (25 %). Principal component analysis (PCA) showed that PC appears to be influenced the most by mites and ticks (MT), myth, natural mortality (NM) and “flood” given their strong loadings. PC2 was heavily influenced by killed for illegal trade (KFIT), accident, and agriculture practices (AP) due to their significant negative loadings. PC3 has NM and AP as the dominant variables, KFIT, also playing a role but in the opposite direction. PC4 showed strong influences from NM (negative) and flood (positive). We concluded that the illegal killing of Indian pangolin is very high. Conservation efforts are crucial to protect these unique and endangered creatures.
