THE GENETIC BASIS OF INTERSPECIFIC FEMALE PREFERENCE IN DROSOPHILA SIMULANS
… regions have been identified that influence female rejection of heterospecific males on the right arm of the third chromosome in Drosophila, however, no individual loci have been identified. Here, I used deficiency mapping to locate regions that influence the rejection of D. melanogaster …

Sensory processing and the evolution of female preference in Neoconocephalus
While the importance of the female preference for exaggerated male traits is largely understood, the evolutionary origins remain under debate. During the evolution of the female preference for leading signals via a sensory bias, an important factor is the processing of sensory information. In …

Female Preference and Prezygotic Isolation In the Fundulus Notatus Species Complex
… natural behavior. To address this limitation, female mate preference was investigated within the <em>Fundulus notatus</em> species complex, where <em>F. notatus</em> and <em>F. olivaceus</em> hybridize at varying rates across replicate contact zones. Using a free-choice design, behavioral …

Investigations of delayed plumage maturation in the orchard oriole
… of molt constraint hypothesis. Finally, I tested female preference for age specific plumage characteristics. I found that females preferred adult males to subadult males in choice experiments with both live and model males.

Male Reproductive Strategies And Mating Displays In The Ocellated Turkey (Meleagris Ocellata)
… of dichotomous male strategies and correlates of female preference for males. The final aim is to investigate the effects of inadvertent human disturbance on the mating system of the Ocellated Turkey, in addition to the fitness of wildlife in general. In the present study, I create the first …

Extrapair mating behaviors in the field sparrow: nocturnal singing and extraterritorial forays
… to announce the presence of extra-pair males to females and that extra-territorial forays serve primarily in prospecting and soliciting extra-pair matings. While forays are common among both male and female Field Sparrows, a higher foraying rate did not result in greater extra-pair paternity …

The role of cultural divergence in reproductive isolation in a tropical bird, the rufous-collared sparrow (Zonotrichia capensis)
… component of reproductive isolation through female mate preference. I investigated the role of cultural divergence in reproductive isolation in a widespread Neotropical passerine the rufous-collared sparrow (Zonotrichia capensis). In Chapter II, I investigated, the role of female preference …

How environments shape ornament morphological evolution: bringing perspective to a century of inconsistent sexual allometry analysis
… third Chapter I used a meta-analysis to reveal female preference experiments generally failed to present females with male display structure sizes informed by allometric data. This implies questions central to sexual allometry theory – that female preferences drive the evolution of …

Harbor Seal (Phoca vitulina) Reproductive Advertisement Behavior And The Effects Of Vessel Noise
… interactions and possibly as an attractant for females. I investigated multiple aspects of these reproductive advertisement displays in a population of harbor seals in Glacier Bay National Park and Preserve, Alaska. First, I looked at vocal production as a function of environmental variables, …

Inbreeding, immunity and male sexual signaling in the black field cricket Teleogryllus commodus
… response and their subsequent attractiveness to females was assessed. There was no effect of LPS injections on male attractiveness. The ICHH predicts that the expression of sexual traits should be positively correlated with immunocompetence. I tested this by measuring courtship and advertisement …

The role of individual variation in auditory and visual processing: implications for mate choice
… in male sexual signals and variation in female sensory perception and behavioral responses to these signals. I addressed several specific research questions using the brown headed cowbird (Molothrus ater) as a model species: (i) how does male signaling behavior differ with the sex of the …

SPECIES RECOGNITION IS DRIVING EVOLUTION OF THE ACOUSTIC MATING SYSTEM OF SHIELD BACK KATYDIDS (ORTHOPTERA: TETTIGONIIDAE: AGLAOTHORAX): BEHAVIORAL AND PHYLOGENETIC EVIDENCE
… Of the variable song characters, I estimated female preferences for pulse number and interpulse interval, the former with choice tests on a Y-maze and the latter with no-choice tests on a locomotion compensator. Females of two coexisting Transverse Range species each discriminated against the …

Behavioral and genomic patterns of evolution during speciation via reproductive and agonistic character displacement
… RCD and ACD can lead to a pattern of enhanced preferences for mating or fighting with conspecifics over heterospecifics in areas of sympatry compared to allopatry. Behavioral isolation can potentially evolve among populations within a species as a correlated effect of RCD or ACD, termed cascade …

Mate choice in the Polychaete nereis acuminata : the role of aggression and parental experience
… species with a unique life cycle. A male and female form a monogamous pair bond, the female lays eggs and dies. The male then fertilises the egg and undertakes sole parental care until the eggs hatch and larvae leave the parental burrow; the male can then reproduce again. This body of work …

The maintenance of variation in Cyprinodontiformes
… a potential reason behind the evolution of a female mating preference for males with novel color patterns in guppies. This preference has been implicated as a factor in maintaining the genetically-determined color pattern polymorphisms found in male guppies, and inbreeding avoidance has been …

Predicting Multi-trophic Consequences of an Emerging Disease
… to compare larval performance and adult female preference of P. palamedes between C. camphora and P. borbonia foliage. My results indicate moderate survivorship on C. camphora (46%) compared to P. borbonia (87%) and there were no differences in first and fourth instar growth rates between …
