Cellular Targets Involved In Reovirus-induced Oncolysis Of RAs-transformed Cells
(Biology, 2008-04-22)Reovirus is a ubiquitous virus with demonstrated oncolytic properties. In this study, we investigate the pathways which reovirus produces a lytic infection in SV-40 transformed WI-38 cells and the noncytocidal infection ... -
Effects Of Nutrient Limitation, Competitors And Grazers On The Abundance And Toxicity Of Laboratory Cultures Of P. parvum, a Harmful Alga
(Biology, 2008-08-08)P. parvum Carter is a haptophyte that occurs world wide in both fresh and brackish waters. Though P. parvum blooms occur world wide under a variety of environmental conditions, it occurs during the cooler months of the ... -
Transposon Exaptation In Mammalian Evolution
(Biology, 2008-08-08)A growing body of work suggests that the exaptation of transposon-derived sequences to perform beneficial cellular functions has played a significant role in eukaryotic evolution. In chapter 1, we present an analysis of ... -
Lack Of Respiratory Effects Of Nicotine Applied To The Caudal Medullary Raphé
(Biology, 2008-08-08)Breathing is an involuntary and automatic process initiated by a network of neurons within the brainstem. These neurons are affected by a number of factors (mechanical, electrical and chemical) that help modulate the ... -
Carbon, Nitrogen And Phosphorus Stoichiometry Of A Mixotrophic Protist
(Biology, 2008-08-08)The microbial loop is one of two major pathways in aquatic systems in which nutrient and energy flow from dissolved nutrients to higher trophic levels. Protozoan-bacteria predator-prey relationships lie at the base of ... -
The Relationship Of Oribatid Soil Mite Abundance To Abiotic And Biotic Factors
(Biology, 2008-08-08)Oribatid soil mites primarily feed on fungi and dead organisms. They belong to the arthropod subclass, Acari, that are believed to contribute to soil processes such as plant litter breakdown and nutrient release. In order ... -
The Effects Of An Artifically Elevated Thermal Environment And Seasonal Acclimatization On The Thermal Tolerance Of The Western Mosquitofish, Gambusia affinis
(Biology, 2008-09-17)Gambusia affinis, the western mosquitofish, is a very hardy, live-bearing fish that has invaded freshwater habitats worldwide. The success of the western mosquitofishs' invasion is due to its reproductive capabilities and ... -
Proteasomal Gene Duplications And Recruitment Of Testis Specific Expression In Drosophila
(Biology, 2008-09-17)Proteasome is a large multisubunit complex that degrades ubiquitinated proteins in a highly regulated manner in all eukaryotes. Two subcompartments of this subunit are the 19Scap and the 20S core particle with 19S acting ... -
How Soil Nutrient Availability Affects Plant Sexual Reproduction And Seedling Recruitment In Alaskan Dry Heath Tundra: Implications For Response To Climate Change
(Biology, 2009-09-16)The harsh growing conditions of the arctic biome, in particular low temperatures and soil nutrient availability, restrict the growth and reproduction of arctic plant species. Recent and ongoing changes in climate are ... -
Sequence Evolution Of Recurrently Recruited Retroposed Genes In Drosophila And Their Possible Role In Meiotic Drive
(Biology, 2009-09-16)Gene duplications are a valuable source of genetic information that can evolve under positive selection creating a new gene function without affecting the original function.A gene duplication mechanism is retroposition. ... -
Morphology And Habitat Use Among Insular Populations Of The Lizard Anolis lemurinus From The Cayos Cochinos Archipelago Of Honduras
(Biology, 2009-09-16)In Honduras, Anolis lemurinus is distributed along the Atlantic versant of the mainland and on the Caribbean island system consisting of the Bay Islands and Cayos Cochinos archipelagos. In the Cayos Cochinos, A. lemurinus ... -
Determining the phylogeographic dynamics of the edge relationships between Aphonopelma hentzi (Girard) and its neighbors along the Colorado River Basin (Araneae, Mygalomorphae, Theraphosidae)
(Biology, 2009-09-16)Theraphosids, commonly known as “tarantulas”, are a group of large, hirsute spiders that have drawn relatively little interest in ecological, behavioral, or evolutionary research from biologists. The lack of research on ... -
Ecomorphology Of The Mexican Fence Lizards Of The Sceloporus Formosus Group (Squamata: Phrynosomatidae)
(Biology, 2009-09-16)A central belief of ecomorphological studies is the link between morphology and performance, but, surprisingly few analyses demonstrate this relationship. Fence lizards of the genus Sceloporus offer a useful system for ... -
Element Stoichiometry Of Ochromonas danica As A Function Of Growth Rate And Temperature
(Biology, 2010-03-03)The microbial loop stresses the importance of flagellated protozoa as predators of bacteria and regenerators of nutrients, the outcome of which affects higher trophic levels. The element stoichiometry of flagellates has ... -
Sex, War And Disease: The Effects Of Infection On Horn Size And Intra-sexual Competition In The Broad-horned Flour Beetle, Gnathocerus cornutus
(Biology, 2010-03-03)Sexual selection is widely used to explain the evolution of mating systems where most often it is manifest as the competition among males for access to females. This competition takes the form of direct male-male interactions ... -
Integration Mechanism Of The Site Specific Non-LTR Retrotransposon, R2Bm
(Biology, 2010-07-19)The focus of this thesis is the mechanistic study of non-LTR retrotransposon replication using the site specific transposon R2Bm. Non-LTR retrotransposons integrate into new chromosomal sites by copying their RNA back ... -
