Conspicuous female ornamentation and male mate preference of Threespine Sticklebacks (Gasterosteus aculeatus)
Wright, Daniel Shane (East Carolina University, 2012)Sexual selection drives the evolution of exaggerated male ornaments (traits showing little function outside social interactions) in many animal species. Female ornamentation is now acknowledged also to be common but is ... -
Conspicuous Female Ornamentation and Tests of Male Mate Preference in Threespine Sticklebacks (Gasterosteus aculeatus)
Wright, Daniel Shane; Pierotti, Michele E.R.; Rundle, Howard D.; McKinnon, Jeffrey S. (2015-03-25)Sexual selection drives the evolution of exaggerated male ornaments in many animal species. Female ornamentation is now acknowledged also to be common but is generally less well understood. One example is the recently ... -
Fishing For The Evolutionary Bases Of Female Ornamentation
Yong, Lengxob (East Carolina University, 2015)Sexual dimorphism, or phenotypic differentiation of the sexes, is widespread amongst animals. It is understood mainly in the context of sexual selection, i.e. selection on mating success, with such selection typically ... -
Gene Expression and the Evolution of Reduced Sexual Dimorphism in a Threespine Stickleback Color Trait
Newsome, William Burns (East Carolina University, 2017-01-03)Elucidating the processes and mechanisms responsible for sexual dimorphism has been a central task for evolutionary biologists since Darwin first proposed the concept of sexual selection. However, our understanding of the ... -
Gene Expression in Male and Female Stickleback from Populations with Convergent and Divergent Throat Coloration

Genetic Architecture of Conspicuous Red Ornaments in Female Threespine Stickleback
Yong, Lengxob; Peichel, Catherine L.; McKinnon, Jeffrey S. (2015-12)Explaining the presence of conspicuous female ornaments that take the form of male-typical traits has been a longstanding challenge in evolutionary biology. Such female ornaments have been proposed to evolve via both ... -
Male Choice in the Stream-Anadromous Stickleback Complex
McKinnon, Jeffrey S.; Hamele, Nick; Frey, Nicole; Chou, Jennifer; McAleavey, Leia; Greene, Jess; Paulson, Windi (2012)Studies of mating preferences and pre-mating reproductive isolation have often focused on females, but the potential importance of male preferences is increasingly appreciated. We investigated male behavior in the context ... -
Melding Research and Education in a Zoological Setting
Foote, Dustin J. (East Carolina University, 2016-07-27)The first zoo was opened in London in 1828 and was intended for scientific study, but was eventually opened to the public in 1847. Since then, public dogma has dictated the development, role, and standards concerning the ... -
Sexual Dimorphism and Trophic Trait Evolution in the Carolina Bay Fundulus Complex
Harrison, Zachary Holt (East Carolina University, 2017-01-05)Convergent evolution in similar environments is widely held to provide some of the strongest evidence for natural selection's role in evolution, and convergent or parallel evolution of reproductive isolation, best studied ... -
STICKLEBACK COLOR FLUCTUATION OVER THE BREEDING SEASON: AN IN DEPTH FIELD STUDY
Bowling, Tyler B. T. (East Carolina University, 2018-07-17)The coloration of the threespine stickleback (Gasterosteus aculeatus) is well studied in the field of evolution, mainly with regard to the role of sexual selection (Ostlund-Nilsson et al., 2006; Foster et al., 2008; Hendry ...
