摘要

摘要:我们比较了喜马拉雅野山羊(Capra sibirica)在巴基斯坦北部两个社区控制狩猎区(CCHA)的种群结构和战利品狩猎统计数据,不同的战利品狩猎持续时间和孤立的西伯利亚野山羊种群。根据2016年至2017年冬季的定点直接计数方法,开伯尔和胡塞尼分别统计了939只和346只野山羊,密度分别为7.5和3.2只。尽管与过去的估计相比,这两个研究地点的西伯利亚C.种群数量都有所增加,但我们发现种群结构和角大小存在差异,可能是战利品狩猎的结果。性别比例在开伯尔向女性倾斜(87名男性/100名女性),在胡塞尼向男性倾斜(115名男性/100位女性)。奖杯大小的雄性占开伯尔人口的7%,胡塞尼人口的11%。开伯尔的平均群体规模为28(范围=1-117),胡塞尼为20(范围=1-79)。开伯尔收获的战利品的平均角大小为102厘米(±范围=91-114),而胡塞尼收获的战利品为108厘米(范围=99-121)。建议采取严格的监管措施来确定许可证的数量。

Predicting the Potential Impacts of Trophy Hunting on Population Structure of Himalayan Ibex (Capra sibirica) in Northern Pakistan
ABSTRACT We compared population structure and trophy hunting statistics of Himalayan ibex (Capra sibirica) in two community-controlled hunting areas (CCHAs) of northern Pakistan with varying duration of trophy hunting and isolated populations of C. sibirica. Based on fixed-point direct count method during winter 2016–2017, 939 ibexes were counted in Khyber and 346 in Hussaini, with a density of 7.5 and 3.2 animals km-2, respectively. Though the populations of C. sibirica at both the study sites have increased compared to the past estimates, we found variations in population structures and horn sizes, presumably as a result of trophy hunting. The sex ratios are skewed toward females in Khyber (87 males/100 females) and towards males in Hussaini (115 males/100 females). The trophy size males were 7% of the population in Khyber and 11% in Hussaini. Mean group (herd) size in Khyber was 28 (range = 1–117) and Hussaini was 20 (range = 1–79). Mean horn size of the trophies harvested in Khyber was 102 cm (± range = 91–114) compared to 108 cm (range = 99–121) in Hussaini. Stringent regulatory measures are suggested to determine the number of permits.
