Mating with more than one male increases reproductive success for female prairie dogs, despite an increase in risks. This is according to a new study published in The Journal of Mammalogy by behavioral ecologist John Hoogland, Professor at the University of Maryland Center for Environmental Science's Appalachian Laboratory.So, if you're a woman looking to have a lot of offspring, polyandry might be a strategy.
Mating entails significant costs such as increased susceptibility to predation and increased exposure to diseases and parasites. So why would a female prairie dog take the risk to mate with multiple males? The answer is simple and clear: female prairie dogs that mate with two or more males rear more offspring than those that mate with only one.
Prairie dogs are herbivorous rodents of the squirrel family, and forage aboveground from dawn until dusk. They live in colonies of territorial, contiguous family groups that contain one or two sexually mature adult males, three or four sexually mature adult females, and one or two sexually immature yearling males.Know any families like that?

I find science fascinating.
