Are extra-pair young better than within-pair young? A comparison of survival and dominance in alpine marmot.

The Journal of animal ecology - 1 Jul 2007

Abstract excerpt

1. In socially monogamous species, females may seek extra-pair copulation to gain genetic benefits. In order to test this 'genetic quality' hypothesis, one must compare the performance of extra-pair young (EPY) and within-pair young (WPY). Such tests, however, are scarce and results published so far are inconclusive. 2. Here, we test the 'genetic quality' hypothesis using multistate capture-recapture models to...
