摘要

为了给极度濒危的西非狮的保护提供信息,我们研究了塞内加尔尼奥科洛科巴国家公园(NKNP)中狮子的种群数量和社会结构。从 2015 年到 2020 年,我们进行了呼唤站和相机陷阱调查,并记录了对狮子的随机观察。狮子的平均密度为 0.50 头/100 平方公里,种群数量估计为 28-56 头。狮子群的平均规模为 2.1 ± 1.45 头(范围为 1-8 头)。单只狮子(43%)、两只狮子(22%)、三只狮子(19%)、四只狮子(4%)和四只以上狮子(5%)之间没有明显差异(X2 = 30.021,P 值 = 0.06452)。性别比例显示雌雄比例为 1:1.1 至 1:2.8。幼狮约占狮群的 13.59%,成年狮和亚成狮分别占 81.22%和 5.17%。根据活动模式分析,北九龙国家公园的狮子主要在夜间(18:00-01:00)和日间(06:00-08:00)活动。与 20 世纪 90 年代末在同一地区进行的早期估计相比,恩卡塔琳娜国家公园的狮子种群数量和密度仍然较低。因此,我们得出结论,必须进一步改善恩科德自然保护区的狮子保护工作,以长期保护这一种群。

Population size and social structure of lions in a west African protected area

To inform the conservation of the Regionally Critically Endangered West African lion, we studied lion population size and social structure in Niokolo Koba National Park (NKNP), Senegal. Calling station and camera trap surveys were conducted and opportunistic lion observations were documented from 2015 to 2020. The average lion density was calculated as 0.50 lion/100 km2 and the population size was estimated as 28–56 individuals. Average lion group size was 2.1 ± 1.45 lions (range 1–8 lions). There were no significant differences between observations of single individuals (43%), groups of two (22%), three (19%), four (4%) and more than four (5%) individual lions (X2 = 30.021, p-value = 0.06452). Sex ratio showed a ratio of male:female of 1:1.1 to 1:2.8. About 13.59% of the lion population was composed of cubs while, respectively, 81.22% and 5.17% were adults and subadults. Based on the analysis of activity patterns, lions in NKNP are mainly nocturno-crepuscular (18:00–01:00) and matutinal (06:00–08:00). Lion population size and density are still low in NKNP compared to earlier estimates from the same area, in the late 1990s. We therefore conclude that the conservation of lions in NKNP must be further improved to safeguard this population in the long term.
