Male mate choice in mosquitofish: personality outweighs body size.

ABSTRACT:

Background

Despite its important implications in behavioural and evolutionary ecology, male mate choice has been poorly studied, and the relative contribution of personality and morphological traits remains largely unknown. We used standard two-choice mating trials to explore whether two personality traits (i.e., shyness and activity) and/or body size of both sexes affect mate choice in male mosquitofish Gambusia affinis. In the first set of trials involving 40 males, we tested whether males would prefer larger females and whether the preference would be affected by males' body length and personality traits, and females' activity level. In the second set of trials (using another 40 males), we tested whether males would prefer more active females and whether the preference would be
