非繁殖期大仓鼠对同种气味的反应和个体间的行为关系

在实验室通过对陌生成年大仓鼠（Ｃｒｉｃｅｔｕｌｕｓｔｒｉｔｏｎ）非繁殖期的气味偏好，性别选择和两鼠间的行为关系的实验研究表明，用Ｙ－型迷宫进行选择测试时，与空白组比较，大仓鼠了同种个体鼠垫的气味，在雌雄巢垫气味之间，雌鼠偏好雄性巢垫的气味，雄鼠不表现性别偏好，与空白组比较，被试鼠选择同种个体；在雌雄个体之间，雄性大仓鼠选择同性个体，雌性不表现性别偏好，在观察箱内，无论同性相遇还是异性相遇，两鼠间攻

Odor preference and behavioral interactions of unrelated and unfamiliar adult ra tlike hamsters ( Cricetulus triton ) were studied during the nonbreeding seaso n in the laboratory.In Y maze,focal hamsters preferred odors of conspecific be dding materials to those of control cotton;focal males' responses did not show a sexual difference between males'and females'odors,while focal females preferr ed males'odors to females'.Focal hamsters spent more time in either arm of Y ma ze with hamster demonstrator than another control arm;focal males spent more ti me in one of arms with same sex hamster demonstrator than another with the oppo site sex individual,while focal females did not displayed such a difference.Th e staged dyadic encounters were conducted in a neutral arena;paired encounters between both same sexes and opposite sexes contained frequent agonistic acts and few amiable acts ;the victors had more attack and flank gland marking than the losers,this indicated flank gland marking was positively related to agonistic behavior and dominant status.
