Anxious mice make lousy dads: study
Date:6/13/2012

Normally, male California mice are surprisingly doting fathers, but new research published in the journal Physiological and Biochemical Zoology suggests that high anxiety can turn these good dads bad.

Unlike most rodents, male and female California mice pair up for life with males providing extensive parental care, helping deliver the pups, lick them clean, and keep them warm during their first few weeks of life. Experienced fathers are so paternal that they'll even take care of pups that aren't theirs. "If we place a male California mouse in a test cage and present it with an unknown pup, experienced fathers will quickly start to lick and huddle with it," said Trynke de Jong, a post-doctoral researcher at University of California, Riverside.

Inexperienced males, on the other hand, aren't always so loving. "Virgin males show more variability," de Jong explained. "They may behave paternally, or they may ignore the pup, or even attack it. We want to understand what triggers these three behavioral responses in virgin males."

De Jong and her colleagues thought this variability might have something to do with social status. In other speciesincluding another rodent, Mongolian gerbilsdominant virgin males are more likely than subordinate ones to kill pups. Perhaps social status influences parenting in California mice as well.

To test this, de Jong and her colleagues paired up 12 virgin males in six enclosures, and performed several tests to see which was dominant. First was a food competition. "If a cornflake is dropped in the cage, the more dominant male will manage to eat most of it," de Jong said. The researchers also observed each mouse's urine marking. "Dominant males will make more, smaller, and more widespread marks than subordinate males," said de Jong

After determining the mightier mouse in each pair, the team tested parental behavior by introducing a pup. Contrary to the hypothesis, scores on the dominance tests
