Title:	MALE SECONDARY SEXUAL TRAITS AND MATING BEHAVIOR IN THE SPECIES DROSOPHILA BIPECTINATADUDA (DIPTERA: DROSOPHILIDAE)
Author:	COOPERMAN, ALISON FAY
Description:	The species Drosophila bipectinata Duda was used in a series of projects aimed at appending empirical support to vital aspects of sexual selection theory, including mechanisms of selection and ‘good genes’ models. The first chapter reports no evidence to support that male vigor, as measured by latency and duration of copulation, can explain the mating success of males larger in body and comb size found in a previous field study. Also, no evidence of female cryptic choice was found in this system. The second chapter reports a genetic association between two condition dependent secondary sexual traits; the finding of a positive association between two traits that differ in kind (sex combs vs. courtship song), and thus presumably have different developmental pathways, provides evidence of the presence of ‘good genes’ in this system. Future directions include testing for evidence of female choice for male D. bipectinata song and/or comb size.
