 | | The second is harem size: mammals that are monogamous or have small harems were more prone to extinction. |
 | | For instance, several duiker species, which are monogamous, died out an average of 10 years after the reserves were established, while the African buffalo, which has harems with about 15 females, is still living in all the reserves. |
 | | Similarly, several colobus monkey species, which have few mates, died out an average of 18 years after the reserves were established, while green monkeys and baboons, which have many mates, are still living in all the reserves. |
