Insects use a spectacular variety of chemical signals to guide their social behaviours. How such chemical diversity arises is a long-standing problem in evolutionary biology. Here we describe the contribution of the fatty acid elongase Bond to both pheromone diversity and male fertility in Drosophila. Genetic manipulation and mass spectrometry analysis reveal that the loss of bond eliminates th...

Male fertility has been largely neglected in demographic research (Coleman, 2000; Greene and Biddlecom, 2000; Zhang, 2011). Although the role of men in fertility decisions and changes has received increased attention since 1990s (DeRose, and Ezeh, 2005; Greene and Biddlecom, 2000; Zulu, 1997), the patterns, levels, changes and determinants of male fertility have remained an understudied researc...

Few aspects of biology are linked to so many evolutionary conflicts as sperm production and fertilization. Segregation distortion and maternal inheritance of cytoplasmic genes, causing maladapted males, are common sources of variation in the competitive ability of sperm, leading males to vary in their intrinsic fertility. Here, I theoretically analyze the effect of such variation in male intrin...
