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 ... -
THE MECHANISM OF ENZYME STABILITY AND SPECIFICITY IN CASPASE-3
(2021-04-20)The caspase family has been found as regulated proteins that play an important role in apoptosis and inflammation. Incorrect caspase regulation may cause serious diseases such as cancer. Knowing the mechanisms and evolution ... -
The Role of the Serine/Threonine Phosphatase PstP in the Mycobacterial Cell Wall Regulation
(2021-12-21)Mycobacterium tuberculosis (Mtb) is the causative agent of the deadly infection Tuberculosis (TB). The current standard antibiotic regimen for TB treatment combines fours drugs to be taken for at least six months. Mtb shows ... -
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 ... -
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 ... -
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 ... -
Toughing it out: understanding the interplay of phenotypic plasticity and evolution in stressful environments
(2019-08-05)Preserving the health of ecosystems on Earth rewards local communities with economic benefits and improved quality of life. Yet, humans often perform activities that disrupt natural systems and lead to declines in biodiversity ... -
TRACING THE DAWN OF THE ELAPIDAE THROUGH THE MOLECULAR SYSTEMATICS AND HISTORICAL BIOGEOGRAPHY OF OLD WORLD CORALSNAKES
(2016-12-20)Much debated since the early 20th century, the evolutionary history and origin of the clinically important family Elapidae is of enormous interest. A persistent lack of higher-level phylogenetic resolution however, has ... -
TRANSCRIPTOMIC SIGNAL OF REPRODUCTIVE MODES AND EARLY SPECIATION IN DAPHNIA PULEX-PULICARIA SYSTEM
(2022-12-16)Daphnia have been gaining recognition as a key model system for studies of evolution, ecology, toxicology, and more recently genomics. The defining characteristic of this particular model system is its phenotypic plasticity ... -
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 ... -
UNCOVERING GENOMIC INSIGHTS TO THE DYNAMICS AND MECHANISMS OF SPECIATION USING LIALIS BURTONIS AND HETERONOTIA BINOEI
(2019-05-08)Species are fundamental entities in biology because their existence represents the cohesion that binds populations into a single unit. One facet of evolutionary biology is to identify the processes that cause the origin ... -
Understanding the role direct contact, toxicity, and mixotrophy play in the population dynamics of Prymnesium parvum
(2019-08-07)Harmful algae disrupt other organisms and ecosystems by multiple mechanisms. Many taxa of harmful algae produce toxic compounds that likely contribute to such problems. Though there is little evidence that the harmful ... -
Urban Ecology in North Texas: Native Plants and Nitrogen Deposition
Globally, the human population continues to grow and move into urban areas causing a range of effects on local ecosystems. Elevated temperatures, altered hydrology, and higher concentrations of atmospheric pollutants in ... -
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, ... -
