Are all prairie voles monogamous?
Prairie voles are meant to be models of monogamy. These adorable rodents form intense lifelong bonds, sticking with the same partner year after year, and raising many generations of pups together. But monogamy doesn’t mean fidelity.
Are montane voles monogamous?
Two types of voles, called prairie voles and montane voles, physically look very similar and have similar nonsocial behavioral repertoires. They differ in that prairie voles are monogamous, whereas the montane vole is promiscuous.
How do prairie voles mate?
Most notable, voles—unlike 97 percent of mammals—are monogamous, forming bonds that last long after mating (often for life, albeit a short one). “Male and female come together, male courts the female so that she goes into estrus, and they mate,” Young explains.
Why do voles fall in love?
They did not allow the animals to mate, but gave the female a dose of oxytocin and the male a dose of vasopressin. With the hormones but without sex, the prairie voles fell in love anyway. “These hormones have the extraordinary ability to turn on or off the development of a pair bond,” Insel explains.
Do voles live in pairs?
Monogamous voles prefer males who have yet to mate, while non-monogamous voles do not. Mate preference in voles develops through cohabitation in as little as 24 hours.
Are voles solitary?
Field voles are solitary and highly territorial animals, fiercely and aggressively defending their territories from intruders.
How many voles are in a litter?
Voles are extremely prolific, with females maturing in 35 to 40 days and having 5 to 10 litters per year. Litter size ranges from 3 to 6 young.
How can you tell if a vole is male or female?
Carefully move the mouse’s tail out of the way so you can see its genital area. If the mouse’s genitals are about 1/4 of an inch away from its anus, the mouse is probably a female. If the genitals are much farther away from the anus, or you can see descended testicles, the mouse is a male.
Do voles live in groups?
There may be two adults, several juveniles, and a nest with up to 5 babies in a family colony. Adults are thought to defend their home habitat or territory from invasion by other voles.
Do voles reproduce quickly?
Voles can breed any time of year, but the peak breeding period is spring. Voles are extremely prolific, with females maturing in 35 to 40 days and having 5 to 10 litters per year.

Are prairie voles sexually monogamous?
Taken together biologists have called this set of behavioural and physical traits “monogamy.” Because prairie vole pairs were sharing a nest and raising babies together, we initially assumed that they also were sexually monogamous. But when we tried to test this assumption, voles of both sexes did not cooperate – often mating with strangers.
What is the difference between monogamy and promiscuity?
Monogamy involves a pair-bond between one male and one female, whereas in polygamy, which includes polygyny, polyandry and polygynandry, social bonds involve multiple males and/or females. Promiscuity refers to the practice of mating in the absence of any social ties.
Why do people choose monogamy over polyamory?

What is the difference between monogamy and polygyny?
In Gunnison’s prairie dogs (Cynomys gunnisoni) for example, monogamy prevails when resources are uniformly distributed whereas polygyny or polygynandry is often found when resources are distributed in patches that are guarded by one or several males (Travis, Slobodchikoff and Keim, 1995).
