摘要

近来,动物对人为环境的适应受到了广泛关注,例如在人为焚烧促进植物再生的焚烧区觅食。然而,在灵长类动物中,有关焚烧后可立即获得的资源利用情况的报道仅限于少数灵长类物种。在这项研究中,我们调查并比较了一群蝙蝠猴(Erythrocebus patas)在新焚烧地区与之前焚烧地区和未焚烧地区的活动预算和食物类别。我们还评估了火灾前后在新焚烧区逗留的时间比例:我们为猴群中的六只成年猴中的五只安装了 GPS 项圈,并比较了它们前往新烧毁地区和未烧毁地区觅食的模式。火灾发生后,巴塔斯猴在新近被烧毁的地区逗留的时间更长,它们到这些地区主要是为了觅食,尤其是觅食烤熟的杨梅种子。此外,帕塔斯猴在新近被烧毁的区域行进的速度更快,步调也更一致。这种 "明显的目标定向 "旅行至少在到达前 1 小时就开始了。结果表明,猕猴群体认识到新近被烧毁的区域是有价值的,尽管这些区域的位置各不相同,但猕猴能够以目标为导向前往这些区域。我们认为,新近烧毁区域的烟雾提供了一种视觉线索,使猴子能够确定烧毁区域的方向。我们的研究结果还支持这样一种观点,即某些灵长类动物具有足够的灵活性,能够适应人为的环境变化并从中受益。

Rushing for "burned" food: Why and how does a group of patas monkeys (Erythrocebus patas) reach freshly burned areas?

Rushing for "burned" food: Why and how does a group of patas monkeys (Erythrocebus patas) reach freshly burned areas?

Recently, considerable attention has been paid to animal adaptations to anthropogenic environments, such as foraging in burned areas where plants are promoted to regenerate by anthropogenic burning. However, among primates, reports on the utilization of resources that are available immediately after burning have been limited to a few primate species. In this study, we investigated and compared the activity budgets and food categories of a group of patas monkeys (Erythrocebus patas) in freshly burned areas by comparing them with those in previously burned areas and unburned areas. We also assessed the proportion of time spent in the freshly burned area before and after the fire: GPS collars were fitted to five of the six adults in the group, and their patterns when they traveled toward freshly burned and unburned feeding areas were compared. Patas monkeys spent more time in freshly burned areas after the fire, and they visited such areas mostly for feeding, particularly on roasted seeds of Cissus populnea. Furthermore, patas monkeys traveled faster and in a more synchronized way toward freshly burned areas. This "apparent goal-directed" travel began at least 1 h before arriving. Results indicate that the group recognized freshly burned areas as valuable, and the monkeys were able to travel in a goal-directed manner to them despite their variable locations. We suggest that smoke from freshly burned areas provides a visual cue with which to orient to the burned areas. Our results also support the notion that some primates are flexible enough to adapt to and benefit from anthropogenic environmental changes.

期刊介绍: Primates is an international journal of primatology whose aim is to provide a forum for the elucidation of all aspects of primates. The oldest primatological journal, Primates publishes original papers that advance the scientific study of primates, and its scope embraces work in diverse fields covering biological bases of behavior, socio-ecology, learning and cognition, social processes, systematics, evolution, and medicine. Contributions relevant to conservation of natural populations and welfare of captive primates are welcome. Studies focusing on nonprimate species may be considered if their relevance to primatology is clear. Original Articles as well as Review Articles, News and Perspectives, and Book Reviews are included. All manuscripts received are initially screened for suitability by members of the Editorial Board, taking into account style and ethical issues, leading to a swift decision about whether to send the manuscript for external review.
