【摘要】 睡眠行为在非人灵长类动物的生活史中占有十分重要地位。关于非人灵长类睡眠地点选择与利用的研究是灵长类行为生态学领域的核心课题之一。本文回顾以往的研究,总结了非人灵长类动物睡眠地点选择的三个主要影响因素,即捕食压力引起的安全因素,睡眠地点的舒适因素和卫生因素;分别对非人灵长类睡眠地点选择的三种主要形式进行了初步的成因讨论,对未来的研究方向进行探索性地展望。更多还原

【Abstract】 Sleeping behavior is a necessary life-sustaining activity for non-human primates,but is especially important in the life history of these animals because they spend approximately half of their lifetime sleeping.After a retrospective literature overview,we found that security(imposed by predation pressure),comfort and sanitation are the main factors affecting the selection and utilization of sleeping site by non-human primates.Non-human primates generally display three different choices of sleep site selection,which include arboreal,ground and nesting.By way of conclusion we discuss the differences between species and related environmental effects.The present paper also provides several promising directions for further research.更多还原
