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 ...
Comparison Of The DNA Methylation Patterns Between Interspecific Xenopus F1 Hybrids And Their Parental Species
(Biology, 2011-07-14)
In this study the main focus is to compare the methylation patterns of interspecific Xenopus F1 hybrids to the parental species using Methyl-Sensitive Amplification Polymorphisms (MSAPs). Genomic DNA was extracted from the ...
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 ...
Intra-specific Variation Across A Small Temperature Difference In The Spider Rabidosa rabida (Araneae: Lycosidae) From The Mountains In Arkansas
(Biology, 2011-07-14)
Temperature affects all levels of biological organization and ultimately affects multiple aspects of ecological performance and fitness. Generalist arthropod predators are ectothermic and are strongly affected by temperature ...
Using Shewanella Baltica Ecotypes As A Model For Transcriptional Variation At The Population Level
(Biology, 2011-03-03)
Eukaryotic studies have shown considerable transcriptional variation among individuals of the same population. Owing to the cost of sequencing entire eukaryotic genomes, tested organisms were assumed to be genomically ...
A Biochemical Approach To Determine The Target Site Recognition Mechanism Of The R2 Retrotransposable Elements
(Biology, 2011-07-14)
Non-LTR Retrotransposons (NLRs) are selfish mobile genetic elements which parasitize the genomes of many organisms including humans. These elements transpose through an RNA intermediate and integrate directly into their ...
