Behavioral Measures and Ecological Correlates of Vision in Poeciliid Fishes
… spatial detail and contrast, (2) correlates of eye size and eye investment across P. reticulata populations that experience different threats from predation and, (3) visual signaling correlates of eye size across the family Poeciliidae.</p><p>The first chapter of this dissertation introduces the …

Vision and Bioluminescence in Cephalopods
… visual group that exhibits a broad diversity of eye adaptations and multiple evolutions of bioluminescence. My research investigates (1) vision and behavior in a deep-sea squid with dimorphic eyes, (2) depth-dependent patterns in cephalopod eye size and visual range, and (3) evolutionary dynamics …

Characterizing the Role of Spegless, a Novel Inner Nuclear Membrane Protein required for spermatogenesis and oogenesis in Drosophila melanogaster
… identified through the screen in the Drosophila eye. Through analysis of adult eye size and photoreceptor organization, several genes were identified as having possible roles in PCP or tissue growth. One gene, which I analyzed further, was a previously uncharacterized gene, CG9723, which I have …

Electrophysiological investigations of the timing of face processing
… of the head was affected by information from eye region and by facial layout: the right N 170 was affected by eye color and by face width, while the left N 170 was affected by eye size and by the relation between the sizes of the top and bottom parts of a face. In contrast, the P100 and the …

A role for environmental epigenetics in the rapid diversification of East African cichlid fishes
… morphologies, accompanied by changes in relative eye size, brain size, pigmentation, and growth patterns. To study the epigenetic basis of these phenotypic changes, I measured chromatin landscape variation in liver from each treatment. Interestingly, the regulatory differences between treatments …

Physiological responses of human retina and choroid to retinal image defocus: Implications for myopia
… is visually guided by local regulation of eye growth. The retina and choroid have been implicated in detecting defocus and relaying information to the sclera to control eye size and thus maintain emmetropia. However, the mechanisms underlying retinal and choroidal responses to defocus …
