Reproductive Traits: Evidence for Sexually Selected Sperm
Sperm exhibit extraordinary morphological divergence yet precise evolutionary causes often remain elusive. A quantitative genetic study sheds light on the major role postcopulatory sexual selection could play in determining sperm size.
متن کاملSearch Behaviour Before and After Search Success
Why do users continue searching after reviewing all relevant documents with which they could have completed a work task? If we knew the answer, then a search system may be able to help users learn about their current search processes, which in turn may enable them to make the whole search process more efficient, leading to greater effectiveness and user satisfaction. This paper is a first step ...
متن کاملCopulatory plugs inhibit the reproductive success of rival males.
Ejaculated proteins play important roles in reproductive fitness. In many species, seminal fluid coagulates and forms what has been referred to as a copulatory plug in the female's reproductive tract. In mice, previous work demonstrated that knockout males missing a key seminal fluid protein were unable to form a plug and less successful at siring litters in noncompetitive matings (one female, ...
متن کاملDevelopment of sexually abusive behaviour in sexually victimised males: a longitudinal study.
BACKGROUND Sexual maltreatment is one of the most common forms of child abuse. To identify risk factors for sexually abusive behaviour by adults, we prospectively assessed childhood experiences and personal characteristics of male child victims who became abusers in later life. METHODS In a longitudinal study (7-19 years duration), we included 224 former male victims of sexual abuse. Risk fac...
متن کاملDo juvenile males affect adult males’ reproductive success in brown-headed cowbirds (Molothrus ater)?
The present study was motivated by a recent anomalous finding between individual competitive performance and reproductive output in brown-headed cowbirds (Molothrus ater). White et al. (2002c) found that adult males who were housed with juveniles outcompeted adults who were housed with other adults when they were brought together to compete for mating opportunities. Although the males in groups...
