Due to shortage of  relationships brides, a female is married to number of males leading to polyandry.
Evidence suggests that polyandrous
marriages are most stable in situations where the brothers have distinct contributions to the household's success.
For Gunnison's and white-tailed prairie dogs, however, polyandrous
females were less likely than monandrous females to survive until the next mating season.
(257.) In a polyandrous
relationship, of course, the hub spouse would be a woman.
subulata females to four males each, in sequence, and then genotyped the resulting offspring using microsatellites to test whether polyandrous
females produce offspring that are half-siblings sired by different males.
Yet, Bombax ceiba flowers conserved the ancestral condition which is represented by synapomorphies characters such as large flower with fleshy cup-shaped calyx, polyandrous
stamens with unilocular anthers that possess stakled filaments forming five bundles united at base with calyx & corolla and produce tremendous amount of pollen which favors pollination via mammals like bats .
Because we were unsure whether these detection ratios would be similar to values that would have been generated using the adjusted total metric, we did not adjust counts of the polygamous (polygynous and polyandrous
) species and assumed perfect detection (detection rate = 1.0).
Finally, pointing out that there are good reasons for not recognising incestuous, polyandrous
or polygamous unions, actually proves, rather than rebuts, our argument.
These birds are territorial, and live in pairs or polyandrous
harems (Sick, 1997; Emlen and Wrege, 2004a; Sigrist, 2006).
The title of this study is a nod to the distinguished ethnologist Claude Levi-Strauss (1908-2009) who demonstrated that multiple family structures (monogamous, polyandrous
