Document Summary
Adaptive significance of male parental care in a monogamous mammal. Parental behavior evolved b/c ale care of young was critical to offspring survival. Parental care enhances offspring survival in a monogamous mammal. Males emancipated from care of young (desert them to seek additional mates) Males forfeit reproductive success if they take care of young (lost mating opportunities) Evidence for fitness benefits of male care in a monogamous mammal. Study is on california mouse, peromyscus californicus - monogamous in the wild, males and. In birds, male presence is important for survival (in other cases, male presence has no effect) females form long-term pair bonds and remain together permanently unless mate dies: males exhibit all parental behavior shown by mothers (except lactation) Used 3 permanently marked study grids compared offspring survival in father-present and father-absent families: objective live trapping. Males removed within 3 days of litter being born.
