Abstract: The identification of species-typical behaviors and establishment of ethograms are fundamental for studying animal behavior and exploring the relationship between environment and behaviors. From August 2013 to April 2014, we used both coastal stationary and mobile tracking methods to observe 8 Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) living in a semi-natural environment located in Tongling Freshwater Dolphins National Nature Reserve. Using focal animal and ad libitum sampling methods, we recorded behaviors and coded them under the “posture-act-environment” (PAE) coding system. A total of 8 postures, 33 acts and 46 behaviors were recorded, and the relative frequency of each behavior related to gender and age was qualitatively described. The ethograms will enable further behavioral research and promote the protection of this animal.

摘要：

识别和编制动物行为谱是深入研究动物行为及其与环境复杂关系的基础和前提。本研究于2013年8月至2014年4月以栖息在铜陵淡水豚国家级自然保护区半自然水域的8头长江江豚为研究对象，采用焦点动物取样法和随机动物取样法观察了动物行为发生的过程、内容和环境，并以“姿势-动作-环境”（posture-act-environment,PAE）为轴心，以行为的功能为依据，构建了长江江豚的PAE行为谱。共分辨记录了半自然水域长江江豚的8种姿势、33种动作和46种行为，并定性描述了不同行为出现频率与年龄组、性别的关系。该行为谱综合了姿势和环境信息，有助于进一步研究长江江豚的生态与行为、促进长江江豚的保护。
