大袋鼠格斗行为的种内种间差异分析

Intraspecific-Interspecific Analysis of Agonistic Behavior in Two Macropus(M.rufus & M.giganteus)

探讨了在接近自然状况下赤大袋鼠和灰大袋鼠格斗行为是否存在种内和种间差异及其影响因素.结果表明两种大袋鼠格斗行为并不一致,种群内中年龄结构是导致不同格斗行为发生的主要因素.这一研究结果对大袋鼠的人工繁育和种群保护有一定的指导意义.

In this research the agonistic behavior of two Macropus： M. rufus and M. giganteus is studied and analyzed in order to discuss whether this behavior is intraspecifically and interspecifically different. The result shows that this behavior varies between species and within species. Moreover, the age structure is the main factor leading to the different agonistic behaviors. These results would be of help for the artificial breeding and population conservation for the Macropus.
