The polygyny threshold model also shows the effects of female reproductive success when multiple females in the same territory mate with one male. In this situation, the female has the option of breeding with an unmated male in a poor-quality territory or with an already-mated male in a high-quality territory.
Polygyny is associated with an increased sharing of subsistence provided by women. This is consistent with the theory that if women raise the children alone, men can concentrate on the mating effort. Polygyny is also associated with greater environmental variability in the form of variability of rainfall. This may increase the differences in ...
Polygyny (/ p ə ˈ l ɪ dʒ ɪ n i /) is a form of polygamy entailing the marriage of a man to several women. The term polygyny is from Neoclassical Greek πολυγυνία (polugunía); from Ancient Greek πολύ (polú) ' many ' and γυνή (gunḗ) ' woman, wife '. [1]
A harem is an animal group consisting of one or two males, a number of females, and their offspring. The dominant male drives off other males and maintains the unity of the group. If present, the second male is subservient to the dominant male.
Of the 1,231 societies listed in the 1980 Ethnographic Atlas, 186 were found to be monogamous, 453 had occasional polygyny, 588 had more frequent polygyny, and four had polyandry. [3] Polyandry is less rare than this figure suggests, as it considered only those examples found in the Himalayan mountain region (eight societies).
A study on the association of alpha males and females during the non-breeding season in wild Capuchin monkeys examined whether alpha males are the preferred mate for females and, secondly, whether female-alpha status and relationship to the alpha-male can be explained through the individual characteristics and or social network of the female.

Polygynandry is a mating system in which both males and females have multiple mating partners during a breeding season. [1] In sexually reproducing diploid animals, different mating strategies are employed by males and females, because the cost of gamete production is lower for males than it is for females. [2]
Polygyny has been widely practiced and celebrated in many cultures and it is the most common and accepted form of polygamy. The word polygyny is often used in reference to humans but it is observed in many animals such as Gorillas , Tigers , Lions , Elk , and Bison .
