Taxonomic and Phylogenetic Revision of the Family Chiasmodontidae (Perciformes: Acanthomorpha)
(2009-08-07)
The family Chiasmodontidae, commonly known as swallowers, comprises four genera and 33 species distributed in the meso and bathypelagic regions of the Atlantic, Pacific, Indian and Southern Oceans. The species of Chiasmodon ...
Regulation of the p62 promoter by oxidative damage in neurodegenerative disease and aging
(2009-06-30)
Oxidative stress is regarded as the damage to a biological system caused by reactive oxygen species (ROS) when the prooxidant overwhelms the antioxidant defense and repair ability. Growing evidence reveals that oxidative ...
Characterization of Viral Communities in Soil, Activated Sludge, and Influent
(2009-07-15)
Viruses are the most abundant yet uncharacterized biological entities on the planet. This thesis is a survey of viral communities in soil, activated sludge (AS), and influent (IN). Both culture-dependent and culture-independent ...
Polyketide Synthase Pathway Discovery from Soil Metagenomic Libraries
(2009-07-21)
Polyketides are structurally diverse bacterial secondary metabolites, many of which have antibiotic or anti-cancer activity. Modular polyketide synthase (PKS) enzymatic complexes contain conserved ketoacyl synthase (KS) ...
Microhabitat Associations of Wintering Birds in a Southeastern Bottomland Forest within the Eastern Gulf Coastal Plain of Florida
(2009-07-16)
I examined microhabitat characteristics affecting the occupancy of wintering birds in a southeastern bottomland forest with repeated point counts at 186 sites. Models were derived a priori based on published literature and ...
Stream-breeding amphibian responses to land use distrubances
(2009-04-29)
Conversion of land from an undeveloped state into agricultural or urban areas is widespread. Urban areas in particular are growing both in size and number globally. Such land use changes can potentially have negative ...
Jaw Morpho-Functional Diversity, Trophic Ecology, and Historical Biogeography of the Neotropical Suckermouth Armored Catfishes (Siluriformes, Loricariidae)
(2009-05-04)
Tropical South America is renowned for its unparalleled biodiversity. Among vertebrates, fish diversity exceeds that of any other group. Estimates of total Neotropical fish richness range between 5000 and 8000 species, of ...
United States Commerce in Live Vertebrates: Patterns and Contribution to Biological Invasions and Homogenization
(2009-05-04)
The trade in live vertebrates is a threat to biodiversity, homogenizing distinct flora and fauna, introducing invasive species and parasites, and depleting wild populations. Because records of live vertebrates imported or ...
Phylogeography and population structure of Antarctic ophiuroids: effects of life history, oceanography and paleoclimatology
(2009-07-01)
The Antarctic landmass and surrounding continental shelf have been isolated for over 24 million years. Geographic and thermal isolation have resulted in a highly endemic, diverse benthic marine fauna. This fauna has been ...
Intraspecific signaling functions of juvenal plumage
(2009-04-22)
The function and evolution of avian plumage coloration has been the subject of many studies over the past decade, but virtually all of this research has focused on the plumages of sexually mature individuals. The color ...
