观察箱内成年雄性布氏田鼠间的行为和行为序

研究了不同大小观察箱内布氏田鼠（Ｍｉｃｒｏｔｕｓ ｂｒａｎｄｔｉ）陌生成年雄性个体间的行为和行为序。在大，小观察箱内，除了追逐行为，优势鼠，从属鼠的行为没有明显的差别。在观察期内，虽然一对鼠中优势鼠的非社会，社会探究，攻击行为都明显地高于从属鼠，但它们在遭遇后的第１个回合的交往中，２只鼠的社会行为没有显示的区别，社会探究，争斗行为之间相互独立，为负相关关系，而其各自内部均为正相关关系，其中社会探究

BEHAVIOURS AND SEQUENCES OF BEHAVIOURS OF ADULT MALE BRANDT'S VOLES IN THE ENCLOSURES

The dyadic behaviours and sequences of behaviours of two unfamiliar adult male Brandt's voles (Microtus brandti) were studied in the large or small enclosure.Except for chasing, there were no significant differences in behavioure of dominant or subordinate between large and small enclosures. The frequency and duration of investigation and aggression of dominant males were significantly higherthan that of subordinates during the whole observation period (10min), however, the differences in social behaviours between dominant and subordinate voles were not significant until the second bout of their encounter. The basic model of behavoural sequences was that nonsocial behaviours, social investigations and agonistic behaviours were independent each other,and they were negatively interrelated, but they had positive internal relations respectively. The main direction of sequence of social investigation was from nose to anogenital area.
