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. ... -
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 ... -
A Study Of Factors Affecting Scale Roughness In The Western Diamondback Rattlesnake (Crotalus atrox)
(Biology, 2007-08-23)Reptilian scales are very complex with patterns across their surface like a human fingerprint. These patterns are species specific, but there has been no way to quantify differences. A new technique using the confocal ... -
Study Of The Expression Pattern Of A Possible Pseudogene And A Functional Retrogene In Drosophila
(Biology, 2007-08-23)Gene duplication occurs when a mutation leads to the copying of a region of DNA that contains a functional gene. After duplication, there will be two copies of the gene in the genome. Gene duplication can have deleterious ... -
A Tale Of Three Phytopathogens: Impact Of Transposable Elements On Genome Evolution
(Biology, 2010-07-19)The genus Phytophthora harbors some notorious plant pathogens like Phytophthora infestans (causal of Irish potato famine), Phytophthora sojae (soybean rot agent), and Phytophthora ramorum (responsible for sudden oak ... -
Targeting Of Site-specific Non-LTR Retrotransposons: Role Of Amino-terminal Domains
(Biology, 2012-04-11)Restriction-like endonuclease (RLE) bearing non-LTR retrotransposons are site-specificelements that integrate into the genome through target primed reverse transcription (TPRT). RLE-bearing elements have been used as a ... -
The Influence Of Thermal Effluent On Life History Evolution In The Western Mosquitofish, Gambusia affinis
(Biology, 2015)The evolutionary consequence of heated effluent on the Western mosquitofish, Gambusia affinis, was studied at Lake Fairfield, in Freestone County, Texas. The Lake Fairfield reservoir receives heated effluent from Luminant’s ... -
Thermal Transgenerational Plasticity and Its Effect on Competitive Ability and Consumer-Resource Dynamics in a Population of Daphnia ambigua
(2015-12-08)Global temperature increases are predicted to quicken in pace this century, and with them so will the likely impact on natural populations. The extent to which organisms will be able to keep pace with and adapt to these ... -
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 ... -
TWENTY YEARS OF LAND USE AND THE IMPACT OF NITRATE, E. COLI AND CHLOROPHYLL FOR TWO LAKES IN NORTH CENTRAL TEXAS
(2021-08-10)Clean and safe drinking water is a human right. Global, federal, and state agencies that monitor the source and quality of drinking water are limited in power and oversight. Historically, human groups have replaced wetland ... -
Use Of A Tri-axial Accelerometer, Behavioral Observation, And GPS To Monitor The Activity Of Female Asian Elephants In A Zoo
(Biology, 2013-07-22)Wild elephants spend approximately 90% of their day actively foraging. Reduced activity in captive elephants may increase the risk of obesity and the formation of stereotypical behaviors. In order to evaluate and enhance ... -
Use Of Reovirus Monoreassortants To Define Lysis Of Transfomed Cells
(Biology, 2007-08-23)Reovirus is known to selectively destroy transformed cells while establishing a persistent infection in normal cells. For this study the transformed cell lines used were L929, WI-38 VA13 2RA, T1, N1, and MYC-3. Additionally, ... -
Use Of Temperature Sensitive Mutants To Map Reovirus Induced Oncolysis
(Biology, 2007-08-23)Reovirus is known to establish persistent infections in normal cells while selectively destroying transformed cells. Individual viruses from each of the ten groups of Reovirus is known to establish persistent infections ... -
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 ...
