摘　　要：哺乳动物婚配制度的研究是行为生态学中具有重要意义的领域之一。研究表明,中缅树鼩Tupaia belangeri的婚配制度主要有一雄一雌制和一雄多雌制2种。为了揭示野外环境下中缅树鼩的婚配制度,本文在繁殖季节测定了雄性中缅树鼩的睾丸质量和体质量,再结合一雄一雌制、一雄多雌制和一雌多雄制的60个灵长类物种进行睾丸质量和体质量的比较分析。结果表明:研究对象的睾丸质量均随体质量增加而增大(r=0.31,P<0.05),睾丸质量和体质量在3种婚配类型之间的差异有统计学意义(睾丸质量:F=11.36,P<0.01;体质量:F=4.09,P<0.05)。不同婚配制度的物种的睾丸尺寸存在差异,中缅树鼩可能属于一雄一雌制婚配动物。研究结果还暗示,哺乳动物的睾丸尺寸可以作为预测其婚配制度的一个“可靠因子”。Studying the mating systems is one of the most significant areas in behavioral ecology. Previously studies showed that the mating system in Tupaia belangeri were monogamy and polygamy. In order to investigate the mating system of T. belangeri in the field environment, testis mass and body mass in male T. belangeri during the breeding season were measured, combined with 60 primate species of monogamy, polygamy and polyandry based on the comparison analysis of testis mass and body mass. The results showed that testis mass increased with the increasing of body mass in all species ( r =0.31 , P <0.05), significant difference in testis mass and body mass among the 3 mating systems (testis mass: F =11.36, P <0.01;body mass: F =4.09, P <0.05) were detected. These results showed that a significant difference of testis mass occurs among different mating systems, and the mating system of T. belangeri may be monogamy. Moreover, the present results suggest that testis size can be used as a reliability factor for predicting the mating system in mammals.
