Introduction
Fitness traits such as survival and fecundity are expected
to increase as a result of natural selection as a population
adapts to a new environment. However, it is more difficult
to make predictions about the evolution male mating
success during adaptation to a new environment because
it is not obvious how or if allelic effects on mating success
change in a new environment. In contrast to the plethora
of empirical data on adaptation with respect to survival
and fecundity, there has been little effort to measure
adaptation with respect to male mating success.
A simple prediction regarding the adaptation of male
mating success is that males evolved in an environment
should have higher mating success than competitors
