IMPACTS OF BLOODBORNE PATHOGEN INFECTIONS ON BREEDING ECOLOGY AND SUCCESS IN WHITE-THROATED SPARROWS (Zonotrichia albicollis)
… parent. White-throated Sparrows are a polymorphic species that mate disassortatively and display alternative reproductive strategies associated with color morph. White-striped birds are more aggressive, more promiscuous, and less parental than their tan- striped counterparts. I examined the …

Melanin as an Oto-Protective Pigment in Two Fish Species: <i> Poecilia Latipinna </i> and <i>Cyprinus Carpio </i>
… dark pigment found in most organisms that gives color to the skin, hair, feathers, and eyes of vertebrates. While melanin is known to also be present in the stria vascularis of the mammalian cochlea, its function in the inner ear is still unknown. Some previous studies have indicated that melanin …

The relationship of time of year, geographic location, insecticide exposure and the genotype of red and green morphs of the tobacco aphid, myzus nicotianae Blackman, in Virginia
… time of season and the genotype of red and green morphs of the tobacco aphid, Myzus nicotianae Blackman, on tobacco was investigated in Virginia in 1988 and 1989. Color morph and karyotype were found to be highly related. The translocated karyotype was associated with the red morphs and the normal …

Hybridization And Introgression In Marine Invertebrates: Population Genomics Of Phymactis Papillosa And Asterias Sea Stars
… in the eastern Pacific coast with the blue color morph representing a genetically distinct and early diverging lineage. Introgression analyses revealed multiple gene flow signals which indicated that the blue morph and the Mexico/ElSalvador population are involved in historical introgression …

A snapshot of color: Exploring the ecological and genetic basis of color variation in the Neotropical tortoise beetle, Chelymorpha alternans (chrysomelidae:cassidinae)
… how life’s diversity is shaped and maintained, color polymorphisms serve as a powerful tool to connect phenotypic variation with the ecological processes that influence them and the genomic factors that maintain them. My dissertation focuses on a polymorphic species within a unique and striking …

Phenotypic and Genetic Diversity in the Sea Urchin Lytechinus Variegatus
<p>Diversity in coloration is a common phenomenon in marine invertebrates, although the ecological significance of the diversity is often unknown. Patterns of geographic variability, particularly with respect to color phenotypes, are evident in many organisms and may provide visual evidence of …

Effects ofUltraviolet Radiation on Newly Settled Recruits of the Reef-building Coral <em>Porites astreoide</em>
… Key, Florida. Twenty adult colonies of the green color morph of <em>Porites astreoides</em> were collected from West end of Bahia Honda and the West end of 7-mile bridge and subsequently held in flow-through tanks for one year under 80% shade cloth. One year later larvae were collected from these …
