In a number of animal species two male types can be distinguished of 'majors' and 'minors' that use different reproductive tactics. Generally majors use pre-copulatory attributes such as weapons or ornaments and minors are thought to invest more in post-copulatory attributes that increase the chances of fertilising ova during or after mating. To test whether minors also invest more in postcopulatory attributes that increase female fecundity (and are thus also useful outside sperm competitions) Tom van den Beuken studies the reproductive strategies of the male-dimorphic bulb mite.
