Outcomes

4

cVA transfer to females

downin flies1

1 study

  1. Artificial selection for male aggression decreases cVA transfer to females in flies.

    “Bully males showed differences in their cuticular hydrocarbon (CHCs) profiles and transferred lower levels of cVA to females”

    Model organismsBully line artificially selected for high male aggressionmales

    Aggressive trait selection influences life-history trade-offs, favoring survival over reproductive success in Drosophila melanogaster males

Mating duration

1 study

  1. Artificial selection for male aggression decreases mating duration in flies.

    “Bully males exhibited lower mating success, shorter mating duration and less effective chemical mate-guarding.”

Lifespan

upin flies1

1 study

  1. Artificial selection for male aggression extends lifespan in flies.

    “However, this was traded-off with increased lifespan, enabling more reproductive opportunities.”
