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 ...
Comparing The Genome Expression Profiles Of Verrucomicrobium Sp. Strain Tav2 Cells Grown Under Two Different Oxygen Concentrations
(Biology, 2010-11-01)
Termites are significantly different in their lifestyles and organization but most are linked by the common trait in degrading plant material, whether it is leaf litter, wood, soil or animal waste. They consume the ...
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 ...
Thermal Tolerance, Physiologic Condition, And Population Genetics Of Dreissenid Mussels (Dreissena polymorpha and D. rostriformis bugensis) Relative To Their Invasion Of Waters In The Western United States
(Biology, 2010-03-03)
Zebra mussels, Dreissena polymorpha, and quagga mussels, D. rostriformis bugensis, Eurasian freshwater bivalves, invaded the North American (NA) Great Lakes in the mid 1980's. Subsequently, they invaded water bodies east ...
Diversity And Community Organization In The Periphyton Of Recirculating Streams Channels Are Defined By Current Velocity And Nutrient Supply
(Biology, 2010-03-03)
In a series of experiments taking place in recirculating artificial stream channels, periphyton communities growing on ceramic tiles were subjected to variations in current velocity and nutrient supply. The first experiment ...
Theoretical And Practical Utility Of Gene Sequences in Phylogenetic and Phylogeographic Analysis
(Biology, 2010-03-03)
Phylogenetics, or the study of evolutionary relationships among organisms, is a rapidly changing field due primarily to the dramatic increase in available molecular characters and increasingly sophisticated theoretical and ...
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 ...
Reproductive Isolation In Drosophila: From Behavior To Genome
(Biology, 2010-11-01)
In this study, I investigate factors underlying reproductive isolation in Drosophila. I begin (Part I) by measuring behavioral isolation between Zimbabwe and cosmopolitan D. melanogaster, and asking the following questions: ...
Analysis Of The Suppressive Effects By Reovirus On Rotavirus Replication During Co-infections
(Biology, 2010-11-01)
Reovirus and rotavirus are both members of the Reoviridae family and commonly occur in children. Rotavirus induced diarrhea is one of the leading causes of death in children under the age of five worldwide. Identifying ...
Characterization Of Anti-rotavirus Activities Of Saponin Extracts From Quillaja Saponaria
(Biology, 2010-11-01)
Rotavirus is the leading cause of severe diarrhea disease in newborns and young children worldwide, estimated to be responsible for over 500,000 adolescent deaths mostly in developing countries each year. Rotavirus-related ...
