Sexual Selection and Mate Preference in Astatotilapia Burtoni
… Does the visual ecology of females shape their preferences for differently colored males?</p> <p>To address these questions, we adopted the African cichlid, <em>Astatotilapia burtoni</em>, that is indigenous to Lake Tanganyika. The cichlid's notable phenotypic diversity, particularly in male …

Preference and affiliation refines the neurotranscriptome pathway for mate preference
Mate choice decisions and behavior contribute to long-term evolutionary outcomes. Understanding the genetic architecture encapsulating mate choice is an important metric in identifying the drivers and variability in those decisions. To address this question, female sailfin mollies (Poecilia …

Conspicuous female ornamentation and male mate preference of Threespine Sticklebacks (Gasterosteus aculeatus)
… Although female sticklebacks often exhibit a preference for red male throat coloration, the possibility of sexual selection on females has been little studied. Moreover, in those species in which female ornaments have been examined, research has often been limited to a single trait. Ornamented …

The effect of female mate preference on the evolution of Batesian mimicry
… in a flight cage to study courtship behavior and mate choice. The study was designed to test the hypothesis that females select the natural color pattern, an important aspect of the theory of the evolution of mimicry. Males were unpainted or were painted either yellow as a control or black to …

Intersexual Communication, Male Mate Preference, and Reproductive Energetics of the Polygynous Lizard, Anolis Carolinensis
… and mating system (communication signals, male mate preference, and reproductive energetics) to contribute to a theoretical model for sexual selection based on a lizard with an intrasexually selected, polygynous mating system. In my first study, I quantified the structure and use of signals …

Reinforcement and cascade reinforcement in the lucania system: the effects of experimental design, sex, and heterospecific pairings on mate preference
… and metrics to determine conspecific or native mate preference in the laboratory. Despite the importance of using assays and metrics that correctly detect reproductive isolation, studies often do not test whether their experimental design accurately measures mate preference. Here, I aimed to …

Female Preference and Prezygotic Isolation In the Fundulus Notatus Species Complex
… operate nonlinearly across space and time, yet mate choice is frequently assessed under artificial conditions that may not reflect natural behavior. To address this limitation, female mate preference was investigated within the <em>Fundulus notatus</em> species complex, where <em>F. notatus</em> …

Aspects of cognition in human mate selection
… regarding what qualities people desire in their mates and why they want them. One study was conducted to replicate previous findings in mate preference using a more sophisticated paired comparison methodology to develop scales. Paired comparison scaling generally replicated gender differences in …

Women’s Status and Trade-Offs in Mate-Preferences
… and social influences on human behaviour. For mate preferences and trade-offs, sex differences are explained via two main theoretical orientations: Evolutionary Psychology (EP) models and Biosocial models. In EP, the differences observed between the sexes are the result of divergent sexual …

Exploring a Mediational Model of the Relationship Between Skin Color and Mate Selection in Desi Young Adults
… South Asian) marriage market, where explicit preferences for fair-skinned marital partners are made and lighter skin is perceived as more attractive. It is also known that, through the halo effect, attractive people are perceived to possess positive personality traits. The present study aimed …

Genetic architecture and ecological speciation in Heliconius butterflies
… they must be accompanied by corresponding mate preferences. Associations between trait and preference loci may be broken down by mating and subsequent recombination. I demonstrate a genetic linkage between loci for both male and female mate preference and wing colour pattern in Heliconius …

The role of cultural divergence in reproductive isolation in a tropical bird, the rufous-collared sparrow (Zonotrichia capensis)
… 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 for and …

Modern technological environments and individual differences in attractiveness perceptions from physical characteristics
… a phenomenon in biology where exposure to novel mates increases mating motivations, usually among nonhuman males, and with some corresponding ‘Coolidge-like’ effects observed in human men. Online environments facilitate access to many novel social, romantic, and sexual partners, potentially …

Communication and sexual selection in the barking gecko (Ptenopus kochi)
