Owl Monkeys Don't Cheat

University of Pennsylvania Intensive fathering plays a role True monogamy is rare in the animal kingdom. Even in species that appear to "mate for life," genetic maternity and paternity tests have revealed that philandering often takes place. Yet a new study by University of Pennsylvania researchers shows that Azara's owl monkeys (Aotus azarae) are unusually faithful. The investigation of 35 offspring born to 17 owl monkey pairs turned up no evidence of cheating; the male and female...

Dr. Kat, America’s sexpert, urges couples to recognize perks of monogamy. Los Angeles, CA (PRWEB) December 17, 2013 Sixty percent of couples in long-term relationships report having a less-than-ideal sex life. Among the other 40%, many are probably fibbing. Is the union of monogamy and monotony inevitable? Must sex with a long-term partner be dull? Dr. Kat doesn’t believe it. In her latest e-book, The Married Sex Solution: A Realistic Guide to Saving Your Sex Life, Dr. Kat argues that...

Oxytocin Makes Men More Attracted To Their Partners
2013-11-26 07:20:07

April Flowers for redOrbit.com - Your Universe Online A biological mechanism has been discovered that could explain the attraction between loving couples. Researchers at the Bonn University Medical Center found that if oxytocin is administered to men and if they are shown pictures of their partner, the bonding hormone stimulates the reward center in the brain, increasing the attractiveness of the partner, and strengthening monogamy. Among mammals, monogamy is not very widespread; humans...

Monogamy Evolved As A Mating Strategy
2013-07-30 05:38:41

redOrbit Staff & Wire Reports - Your Universe Online The evolution of monogamy among male mammals appears to have been triggered by the threat of infants being killed by unrelated males, researchers reported on Monday in the journal PNAS. The study is the first to reveal this evolutionary pathway for the emergence of pair living, and contradicts the theory monogamy resulted from a need for extra parental care by the father. The researchers also found males were more likely to...

Diverse Activity Patterns Of Birds During The Arctic Breeding Season
2013-06-19 11:17:58

Max-Planck-Gesellschaft Our internal circadian clock regulates daily life processes and is synchronized by external cues, the so-called Zeitgebers. The main cue is the light-dark cycle, whose strength is largely reduced in extreme habitats such as in the Arctic during the polar summer. Using a radiotelemetry system a team of researchers from the Max Planck Institute for Ornithology have now found, in four bird species in Alaska, different daily activity patterns ranging from strictly...

Are You My Daddy? Infidelity And Paternity In Reed Warblers
2013-05-16 12:05:08

University of Veterinary Medicine Vienna Many species pair for life, or so the story goes. In reality, there is quite a bit of cheating going on. Both male and female partners may have “affairs” outside the pair bond. In such cases, how is a male to know if the chicks he is feeding are really his? Depending on the species, males have different strategies. They may try to ensure paternity by increased surveillance and fighting off the competition, or by having more frequent sex...

Healthier Babies From Better Looking Birds

BioMed Central A female great tits' (Parus major) appearance is shown to signal healthy attributes in offspring in a paper in BioMed Central's open access journal Frontiers in Zoology. The black stripe across her breast and white patches on her cheeks correlate to a chick's weight at two weeks and immune strength respectively — though the former seems to signal a genetic benefit and the latter can affect an 'adopted' chick's health, suggesting nurture is involved. Taking two...

Monogamous Owl Monkeys Reproduce More Than Those With Multiple Partners
2013-01-25 11:12:27

University of Pennsylvania Breaking up is hard to do – and can be detrimental to one´s reproductive fitness, according to a new University of Pennsylvania study. Focusing on wide-eyed, nocturnal owl monkeys, considered a socially monogamous species, the research reveals that, when an owl monkey pair is severed by an intruding individual, the mate who takes up with a new partner produces fewer offspring than a monkey who sticks with its tried-and-true partner. The findings...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
