Assessing conserved function of conidiation regulators in two distantly related ascomycetes, Aspergillus nidulans and Neurospora crassa
(2012-07-16)Conidiation is a common and critical asexual reproductive mode in fungi. The ascomycetes, the largest group in the kingdom Fungi undergo conidiation. The wide array of morphological difference in a conidiophore and conidial ... -
Convergent Evolution in Livebearing Fishes
(2012-07-16)The directionality and consistency of evolution has long been a subject of contention among evolutionary biologists since the days of Darwin. However, it is unknown how much can be quantified and how much results from ... -
Epperson v. Arkansas : a question of control over curriculum and instruction decision making in the public schools
(Texas A&M University. Libraries, 1978)Public education is a function of state and local governments. Every state has laws which prescribe those things which must be contained in the curriculum, and in some instances directions for instruction. Although the ... -
Evolution of Memory in Reactive Artificial Neural Networks
(2012-07-16)In the neuronal circuits of natural and artificial agents, memory is usually implemented with recurrent connections, since recurrence allows past agent state to affect the present, on-going behavior. Here, an interesting ... -
Genetic interactions among three chromosomal races of the Geomys bursarius complex (Rodentia: Geomyidae)
(Texas A&M University. Libraries, 1982)Genetic relationships among three races of the plains pocket gopher, (Geomys bursarius complex) were determined using data from chromosome banding, meiotic analysis, and protein electrophoresis. Race E (2n = 74, FN = 72) ... -
Genome size evolution in the class Mammalia
(Texas A&M University. Libraries, 1992)In this study, intra- and interspecific genome size variation was assessed among species within the Order Chiroptera. Outgroup taxa from the Orders Dermoptera and Primates also were examined. This study additionally addressed ... -
Genomic Insights into Sexual Selection and the Evolution of Reproductive Genes in Teleost Fishes
(2012-10-19)Sexual selection has long been a working explanation for the elaboration of appreciable traits in plants and animals, but the idea that it is an equally potent agent of change at the level of individual molecules is ... -
Geographic variation in Lepomis megalotis (Rafinesque) (Osteichthyes: Centrarchidae

I Like it When You Act Like a Leader: A Role Congruity Account of Romantic Desire for Powerful Opposite-Sex Others
(2013-01-11)Powerful people perform observable agentic behaviors (e.g., directing tasks), and people expect powerful people to act in these agentic ways. Furthermore, Role Congruity Theory predicts that people are disliked when their ... -

(2013-09-24)This research is an attempt to implement various artistic aesthetics inspired by the world wars into a fictional narrative focused an artist’s struggle in wartime. Works by Tristan Tzara, William Burroughs, Andre Breton, ... -
Pheromonal Mechanisms of Reproductive Isolation in Xiphophorus and Their Hybrids
(2018-08-26)Pheromones play an important role in conspecific mate preference across taxa. While the mechanisms underlying the pheromonal basis of reproductive isolation are well characterized in insects, we know far less about the ... -
Sexual Recombination and the Development of Complex Phenotypes
(2017-07-24)Adaptive laboratory evolution facilitates the development and study of complex phenotypes. In an evolving population, individuals with mutations conveying a fitness benefit are selected for, and become enriched, in the ... -
Some Philosophical Origins of an Ecological Sensibility
(2012-10-19)This dissertation is centered on problems within the history and philosophy of biology. The project identifies the philosophical roots of the current ecological movement and shows how a version of philosophical naturalism ... -
Structural and stratigraphic evolution of Shira Mountains, central Ucayali Basin, Perú
(2009-05-15)The Ucayali Basin is a Peruvian sub-Andean basin that initially formed during the extensive tectonics of the Early Paleozoic. Originally, the Ucayali Basin was part of a larger basin that extended east of the current ... -
The Evolution & Regulation of Physical Activity Levels
(2019-07-25)Physical activity is a well-established preventative for many diseases, yet the average United States citizen does not engage in regular exercise. Thus, there is a need to understand the biological and environmental ... -
The Evolution and Ecology of Capitella (Annelida, Capitellidae) in the Gulf of Mexico
(2020-05-04)Members of genus Capitella (Annelida: Capitellidae) are often found in high abundance in areas of anthropogenic disturbance, such as fish farms and waste-water outflow sites and are frequently cited as ecological indicators ...
