PRE- AND POST-COPULATORY SEXUAL SELECTION IN THE TORTOISE BEETLE ACROMIS SPARSA (COLEOPTERA: CHRYSOMELIDAE)
… is dependent on traits used during both the pre-copulatory processes influencing mate acquisition, as well as the post-copulatory processes influencing fertilization. However, few studies have simultaneously examined pre- and post-copulatory sexual selection within a particular species, and we …

The adaptive significance of multiple mating by males in the polygynandrous waterstrider Aquarius remigis (Heteroptera: Gerridae)
… species, sperm competition and female post-insemination processes may influence male paternity success. Hence, insemination (i.e. successful sperm transfer) may not guarantee reproductive success for the male. Using a variation of Parker's (1970) sterile (irradiated) male technique, I …

An Assessment of the Effects of Sexual Selection and the Social Environment on Mating Behaviors in Two Tiger Beetle Species (Coleoptera: cicindelidae)
… (SSD) are expected to occur in taxa with post-copulatory mate guarding due to selection for male choice of large females when male time investment is high. Both species displayed female-biased SSD, but size assortative mating did not occur in the field. However, the mean size of mating C. …

The effect of gregarine parasite infections, age, and diet on calling song structure and mating behaviour in the Texas field cricket, Gryllus integer
… mated were observed for performance of 8 post-copulatory guarding behaviour displays. None of the guarding behaviours were affected by parasite load. However, one display was affected by age, with older males performing guard turning for shorter durations than younger males. Results are …

Imagining the Internal Reproductive Environment: Function and Evolution of the Drosophila Melanogaster Female Reproductive Tract
… the necessity of concordant changes to support post-mating functions. In my second chapter, I conducted a proteomics analysis of the female reproductive tract that demonstrates the unique composition and response to mating of the extracellular female reproductive tract fluid as compared to the …

Sexual Selection in Mantled Howling Monkeys (Alouatta palliata), With an Emphasis on the Role of Female Mate Choice
… paternity data leaves open the possibility of post-copulatory female choice. However, explanations exist for the apparent lack of female mate choice in this species. Because males must attain alpha status to remain in a group, differences in inherent quality may be low among group males. The …
