Sexual selection in a lekking Hawaiian Drosophila: the roles of male competition and female choice in male mating success
Article Abstract:
The importance of sexual selection in Drosophila grimshawi is investigated. Results show that mating success is significantly correlated with the amount of time males spent engaged in sexual activity at lek sites over their lifetimes, and the amount of time a male spentsexually displaying at these sites is significantly correlated with live weight. Moreover, male size is strongly influenced by environmental conditions during the larval phase, environmental factors have a large influence on male mating success.

Environmental influences on male courtship and implications for female choice in a lekking Hawaiian Drosophila
Article Abstract:
The amount of protein content in the diet of male lekking Hawaiian Drosophila significantly influences its courtship behavior, number of offsprings, and female preference in mate selection. Males fed with high protein diets are physically superior, court more frequently than males fed with low-protein diet. Matings involving high-protein-fed males produced more eclosing offsprings than matings involving low-protein fed-males.

Females lay fewer eggs for males with greater courtship success in a lekking Drosophilia
Article Abstract:
Although much research has been conducted on female mate choice in lek mating systems, it usually revolves around possible indirect benefits for the female to be discriminating. This research specifically seeks to determine if females get direct benefits, such as produce more offspring, by choosing a more sexually vigorous male.
