【摘要】 在实验室条件下对捕自杭州市郊的11只社鼠(3♂,8♀)个体相遇时的叫声与行为进行观察和记录,其结果表明,社鼠不同个体相遇后存在4种叫声,即雄性个体相遇打斗时败者的叫声、雌性个体相遇打斗时败者的叫声、异性成体相遇时雌体的叫声和成幼体相遇时幼体的叫声。进一步比较分析显示,各种叫声的主要声学参数之间大多存在着极显著差异。同性个体打斗后,败者的叫声和幼体见到成体时的叫声均呈现为多谐变音的频谱结构,这可能是对强者的惧怕叫声;而异性个体相遇时,雌体的叫声呈现为多谐恒频的频谱结构,这可能是对雄体的拒斥叫声。更多还原

【Abstract】 The voices of 11 individuals (3♂, 8♀) of Chinese White-bellied Rat (Niviventer confucianus) from field and their behaviors were recorded and observed in different individual encountering settings in captive. The results showed that Chinese White-bellied Rat made 4 kinds of voices in different individual encountering situations, i.e. defeated male’s voice, defeated female’s voice, female’s voice when male occurred and young’s voice when adult occurred, and the significant differences on values of most measured acoustic parameters between voices could be found. The acoustic characters based on our studies suggested that Chinese White-bellied Rat might have two types of voices when individuals encountered each other: One is fearing call with multi-harmonic frequency conversion, including defeated individual’s voice and young’s voice when adult occurred; another is rejecting call with multi-harmonic constant frequency, such as female’s voice when male occurred.更多还原
