Geladas are the most distinctive of Ethiopian endemic mammals, representing the last extant species of primate genus that have a very restricted distribution in the northern Ethiopian plateau. The activity budget and feeding ecology of geladas () were studied around Abogedam Church, Ethiopia, from May to October 2014, encompassing dry and wet seasons. The scan sampling method was applied to collect behavioural data on the identified band. Activity scans were collected at 15-minute intervals for up to five minutes duration from 0700 to 1730 h. The activity recorded for each individual was the first activity that lasts for five seconds. During each scan, individuals were recorded as performing activities: feeding, moving, resting, playing, aggression, grooming, sexual activity, and others. On average, geladas devoted 57.19% feeding, 14.82% resting, 14.92% moving, 4.83% playing, 2.53% aggression, 4.14% grooming, 1.23% sexual activity, and 0.34% other activities such as vocalization, defecation, and urination. Forty-one plant species were consumed by geladas that belonged to 18 families of which 53.66% were grasses. This study provides basic information on further studies and motivates conservationists to plan the management of unprotected areas at the vicinity of agricultural lands where such endemic animals dwell.
狒狒是埃塞俄比亚特有哺乳动物中最具特色的物种,代表了在埃塞俄比亚北部高原上分布非常有限的最后一种灵长类属现存物种。2014 年 5 月至 10 月,在埃塞俄比亚 Abogedam 教堂周围对狒狒的活动量预算和觅食生态进行了研究,涵盖了旱季和雨季。采用扫描取样法对已识别的群体收集行为数据。从 0700 到 1730 小时,以 15 分钟的间隔收集长达五分钟的活动扫描。每个个体记录的活动是持续五秒钟的第一个活动。在每次扫描中,个体被记录为执行以下活动:觅食、移动、休息、玩耍、攻击、梳理、性行为和其他活动。平均而言,狒狒有 57.19%的时间在觅食,14.82%的时间在休息,14.92%的时间在移动,4.83%的时间在玩耍,2.53%的时间在攻击,4.14%的时间在梳理,1.23%的时间在进行性行为,还有 0.34%的时间在进行其他活动,如发声、排便和排尿。狒狒食用了 41 种植物,分属于 18 个科,其中 53.66%是草类。本研究为进一步的研究提供了基础信息,并促使自然资源保护主义者计划对这些特有动物栖息地附近的未受保护区域进行管理。
