Investigating The Diversity Of Single-Stranded Dna Bacteriophages In Marine Environments, Max Stephen Hopkins
USF Tampa Graduate Theses and Dissertations
There are estimated to be 1030 virus-like particles in the world's oceans. Most are viruses that infect bacteria, called `bacteriophages' or simply `phages'. Phages exert tremendous influence on marine biogeochemical cycling because they are responsible for about half of all bacterial death in the oceans, causing nutrient release into the dissolved and particulate organic matter pools. Traditional paradigms of phage biology held that most of these ocean phages belonged to the Caudovirales group: phages that contain a double-stranded DNA genome within a geometric capsid `head' to which a `tail' is joined, in one of several morphological variants, that is the …

Marine Viral Diversity And Spatiotemporal Variability, Dawn Goldsmith
USF Tampa Graduate Theses and Dissertations
Marine viruses are the most numerous biological entities in the ocean, with an estimated abundance of 4 x 1030. They merit study not only because of their sheer abundance, but also because of the role they play in the Earth's biogeochemical cycles. Viral lysis of bacteria redirects the flow of nutrients among marine microbes, which ultimately affects the efficiency of the biological pump. Viral diversity is important because most viruses are host-specific. In preying on a certain type of bacteria, viruses affect the diversity and structure of the bacterial community, leading to changes in carbon and nutrient flows. …
