Abstract

ABSTRACT Comparative behavioural research reveals both intra- and inter-species diversity among primates. Few long-term behavioural studies have been conducted on African nocturnal primates. Here we describe and compare behavioural and ecological observations on two species of pottos (Perodicticus ibeanus and P. edwardsi) across ten sites. We observed a total of 51 P. edwardsi and 28 P. ibeanus. We recorded all 21 postures within an established lorisid ethogram, as well as 42 of 50 behaviours. Eating, locomotion, freezing, resting and sniffing were the most common behaviours. We recorded behaviours not previously described for perodicticines, including bark chewing and unique vocalisations. Three species of pottos are now recognised, with potentially more species to be revealed within this cryptic and nocturnal genus. Although there are similarities among potto species, we show that unique ecological adaptations and behaviours may further elucidate their diversity.
安哥拉、喀麦隆、肯尼亚、尼日利亚、卢旺达和乌干达的东部周期马铃薯和中部爱德华马铃薯的比较生态学和行为
比较行为学研究揭示了灵长类动物种内和种间的多样性。对非洲夜行灵长类动物进行的长期行为研究很少。在这里,我们描述并比较了在十个地点对两种马铃薯(Perodicticus ibeanus和P. edwardsi)的行为和生态观察。我们一共观察到51只edward P.和28只ibeanus P.。我们记录了所有21种姿势和50种行为中的42种。进食、运动、冻结、休息和嗅闻是最常见的行为。我们记录了以前没有在期刊中描述的行为,包括树皮咀嚼和独特的发声。现在已经确认了三种马铃薯,在这个神秘的夜间植物属中可能会发现更多的物种。尽管盆栽物种之间存在相似性,但我们表明独特的生态适应和行为可能进一步阐明它们的多样性。
