Seasonal diets of the gemsbok (Oryx gazella gazella) at Mason Mountain Wildlife Management Area, Mason County, Texas
(2002-12)I investigated the seasonal diets of gemsbok antelope (Oryx gazella gazella) at Mason Mountain Wildlife Management Area using microhistological analysis of fecal pellets. Plants in 2,000 samples were identified to ... -
Megastrombilus development in Juniperus ashei (Cupressaceae)
(2004-12)Juniperus ashei Buchh. (Cupressaceae) is a common gymnospermous tree in central Texas. Its range extends from the mountains of northwestern Coahuila northeast through Texas, eastern Oklahoma, northwestern Arkansas ... -
Developmental appearance of phosphorylated intermediate filaments in nuclei of glioma and neuroblastoma cells
(2002-05)The structure and function of the proteinaceous skeleton in the nucleus of eukaryotic cells, termed the nucleoskeleton, is only vaguely known. Investigations into the role of intermediate filaments (IF) in the nucleus have ... -
The role of natural enemies in determining the relationship between gall size and emergence success of a host-specific cynipid
(2000-12)Large gall size is considered an adaptation to avoid parasitism for a number of insect gall-formers when gall size is positively correlated with emergence success and negatively correlated with the probability of parasitism. ... -
Identification and molecular characterization of two novel Arabidopsis mutants that are resistant to auxin
(2009-08)Auxin is a pivotal plant hormone that plays a major role in plant growth and development. While indole-3-acetic acid (IAA) is the major natural auxin found in plants, there are many synthetic chemicals with auxinic ...

Using motion-triggered cameras to estimate habitat use by collared peccaries
(2004-12)Motion-triggered cameras (MTC) are used in a variety of wildlife research applications; however, few studies outline how to use MTC to collect reliable data on habitat use. Herein I outline how to use MTC for collecting ... -

Male mate choice in relation to female size in the sailfin molly, Poecilia latipinna
(2007-08)No abstract prepared. -
Testing reintroduction potential of Abronia macrocarpa (Nyctaginaceae)
(2007-12)This study tests reintroduction as a mechanism to assist in recovery of Abronia macrocarpa, a federally and state endangered plant endemic to Texas. A series of laboratory tests were conducted to determine the most ... -
Carbachol-induced pigment granule dispersion
(2000-12)The retinal pigment epithelium (RPE) is a monolayer of pigmented, simple cuboidal epithelium with long apical processes that interdigitate with photoreceptors. In teleosts, the RPE aids in light adaptation through pigment ... -
A comparative analysis of plant species distribution and growth response to edaphic features between the San Saba River and a tributary
(2013-05)Riparian corridors are often a mosaic of vegetative communities that serve as interfaces between terrestrial and aquatic systems and, consequently, span multiple environmental gradients. As such, an interesting question ... -
The distribution of the water flea (Cladocera: Daphnidae) in a central Texas reservoir
(2001-05)No abstract prepared. -
Assessment of content area knowledge, writing skills, and higher order thinking skills of students participating in an entry-level biology major's course
(2002-08)Current curriculum reform trends in science education have led many institutions to revamp their programs from those incorporating traditional direct teaching style lectures and labs to those integrating inquiry driven, ... -
A survey for potential predators of the golden-cheeked warbler (Dendroica chrysoparia) in relation to different edges at the Balcones Canyonlands Preserve
(2006-05)The Golden-cheeked Warbler (Dendroica chrysoparia), an endangered neotropical migrant, has a restricted breeding range in central Texas. Because of their sensitivity to habitat loss, fragmentation, and limited breeding ... -
Evolutionary consequences of hybridization in the Lycaeides species complex
(2006-11)Hybridization-here defined as mating between differentiated populations-has several evolutionary consequences (Arnold 1997, Mallet 2005). If hybrids have reduced fitness compared to the parental populations, then selection ...

Diurnal expression of muscarinic and dopaminergic receptors in the eye of zebrafish /by Elizabeth Louise Capalbo
(2009-12)Diurnal rhythms allow organisms to synchronize physiological functions, such as feeding habits, with environmental cues such as light and temperature. Much is known about the diurnal and/or circadian regulation of ... -
Nesting ecology and ontogeny of hatchling Neotropic Cormorants (Phalacrocorax brasilianus)
(2004-05)The Neotropic Cormorant is one of the most widely ranging members of its genus. The justification of lethal control of piscivorous birds to protect fisheries requires a firm understanding of the population status and ...

The Genomics of Speciation
(2018-12)Speciation, the process by which reproductive isolation evolves between diverging lineages, is pivotal to our understanding of evolution. Across multiple wild populations I explored the genetic architecture of reproductive ... -
Assessment of the Small Indian Mongoose (Herpestes auropunctatus) in sustaining Cattle Fever Tick populations in Puerto Rico
(2018-12)The ectoparasite Rhiphicephalus (Boophilus) microplus, also referred to as Cattle Fever Tick (CFT), serves as the primary vector for the protozoan pathogen Babesia which causes bovine babesiosis in livestock and wildlife ...
