Mating strategies are the key to understanding both reproduction and evolution. The majority of the previous work on the mating strategies of the Sichuan snub-nosed monkey (Rhinopithecus roxellana), a polygynous species, has concentrated on the character of sexual behavior between heterosexual individuals, mating patterns, and the seasonality of mating and births in captivity and in wild. The importance of multiple copulations of them, both wild and captivity, has so far been neglected. 相似文献
