Conservation And Conflict Between Endangered Desert Fishes, Jennifer M. Gumm, Jennifer L. Snekser, Murray Itzkowitz

Faculty Publications

Conservation of naturally sympatric endangered species requires unique considerations. While impacts of invasive species garner much attention, interactions between endangered species must also be managed. The endangered Leon Springs pupfish, Cyprinodon bovinus, has suffered a population decline due to decreasing natural habitat. As breeding habitat is lost, C. bovinus is also adversely affected by the sympatric, endangered Pecos gambusia, Gambusia nobilis. Here, we document interactions between these species, finding significantly more G. nobilis accumulated at pupfish spawning events than randomly distributed on breeding grounds in the absence of spawning. As a known egg predator, our results suggest that G. nobilis …

Epigene And Hypogene Karst Manifestations Of The Castile Formation: Eddy County, New Mexico And Culberson County, Texas, Usa, Kevin W. Stafford, Raymond Nance, Laura Rosales-Lagarde, Penelope J. Boston

Faculty Publications

Permian evaporites of the Castile Formation crop out over ~1,800 km2 in the western Delaware Basin (Eddy County, New Mexico and Culberson County, Texas, USA) with abundant and diverse karst manifestations. Epigene karst occurs as well-developed karren on exposed bedrock, while sinkholes dominate the erosional landscape, including both solutional and collapse forms. Sinkhole analyses suggest that more than half of all sinks are the result of upward stoping of subsurface voids, while many solutional sinks are commonly the result of overprinting of collapsed forms. Epigene caves are laterally limited with rapid aperture decreases away from insurgence, with passages developed along …

Hypogenic Speleogenesis Within Seven Rivers Evaporites: Coffee Cave, Eddy County, New Mexico, Kevin W. Stafford, Lewis Land, Alexander Klimchouk

Faculty Publications

Coffee Cave, located in the lower Pecos region of southeastern New Mexico, illustrates processes of hypogenic speleogenesis in the middle Permian Seven Rivers Formation. Coffee Cave is a rectilinear gypsum maze cave with at least four stratigraphically-distinct horizons of development. Morphological features throughout the cave provide unequivocal evidence of hypogenic ascending speleogenesis in a confined aquifer system driven by mixed (forced and free) convection. Morphologic features in individual cave levels include a complete suite that defines original rising flow paths, ranging from inlets for hypogenic fluids (feeders) through transitional forms (rising wall channels) to ceiling half-tube flow features and fluid …

Attitude And Divergence In Business Students: An Examination Of Personality Differences In, Todd A. Brown

Faculty Publications

Many studies have reported that economics and business students have been more apt to act in self-interested ways when compared to their counterparts in other academic fields. It is our contention that past studies have not shed light on the underlying psychological differences which might be leading to this difference in behavior. We put forth evidence that certain business majors are correlated with a marked increase in levels of narcissism and decreased levels of empathy, as measured by psychological personality tests.

Castile Evaporite Karst Potential Map Of The Gypsum Plain, Eddy County, New Mexico And Culberson County, Texas: A Gis Methodological Comparison, Kevin W. Stafford, Laura Rosales-Lagarde, Penelope J. Boston

Faculty Publications

Castile Formation gypsum crops out over ,1,800 km2 in the western Delaware Basin where it forms the majority of the Gypsum Plain. Karst development is well recognized in the Gypsum Plain (i.e., filled and open sinkholes with associated caves); however, the spatial occurrence has been poorly known. In order to evaluate the extent and distribution of karst development within the Castile portion of the Gypsum Plain, combined field and Geographic Information System (GIS) studies were conducted, which enable a first approximation of regional speleogenesis and delineate karst-related natural resources for management. Field studies included physical mapping of 50, 1-km2 sites, …

Hypogene Speleogenesis Within The Central Basin Platform: Karst Porosity In The Yates Field, Pecos County, Texas, U.S.A., Kevin W. Stafford, Fred H. Behnken, Jesse G. White

Faculty Publications

The Yates Unit Oil Field is located on the southeastern tip of the Central Basin Platform in eastern Pecos County, Texas. It produces from Middle Permian strata, primarily the upper San Andres Formation. Locally, the productive upper San Andres Formation is comprised of successively vertically stacked progradational shelf carbonates. Stratigraphically overlying the Yates Field reservoir, the Toborg Field produces from the uppermost Triassic and Cretaceous units. Both fields are bounded on the north and east sides by the Pecos River, which has remained entrenched in its current location since the early Tertiary. As mapped, the top of the San Andres …

Hypogene Calcitization: Evaporite Diagenesis In The Western Delaware Basin, Kevin W. Stafford, Dana Ulmer-Scholle, Laura Rosales-Lagarde

Faculty Publications

Evaporite calcitization within the Castile Formation of the Delaware Basin is more widespread and diverse than originally recognized. Coupled field and GIS studies have identified more than 1000 individual occurrences of calcitization within the Castile Formation outcrop area, which includes both calcitized masses (limestone buttes) and laterally extensive calcitized horizons (limestone sheets). Both limestone buttes and sheets commonly contain a central brecciated zone that we attribute to hypogene dissolution. Lithologic fabric of calcitized zones ranges from little alteration of original varved laminae to fabrics showing extensive laminae distortion as well as extensive vuggy and open cavernous porosity. Calcitization is most …

Use Of Trees By The Texas Ratsnake (Elaphe Obsoleta) In Eastern Texas, Josh B. Pierce, Robert R. Fleet, Lance Mcbrayer, D. Craig Rudolph

Faculty Publications

We present information on the use of trees by Elaphe obsoleta (Texas Ratsnake) in a mesic pine-hardwood forest in eastern Texas. Using radiotelemetry, seven snakes (3 females, 4 males) were relocated a total of 363 times from April 2004 to May 2005, resulting in 201 unique locations. Snakes selected trees containing cavities and used hardwoods and snags for a combined 95% of arboreal locations. Texas Ratsnake arboreal activity peaked during July and August, well after the peak of avian breeding activity, suggesting arboreal activity involves factors other than avian predation.

Delta Function For An Affine Subspace, Jeremy Becnel

Faculty Publications

The Kubo–Yokoi and Donsker delta functions are well known generalized functions in infinite dimensional distribution theory. In this paper we develop the delta function for an affine subspace and show that it is a generalization of the Kubo–Yokoi and Donsker delta functions. The Wiener– Itˆo expansion of the delta function for an affine subspace is also given.

Cultural Variations In Parenting And Implications For The Counseling Professional, Le'ann L. Solmonson

Faculty Publications

In a culturally diverse society, counselors are faced with providing effective treatment that is culturally responsive and meets the needs of the client. Counselors have an ethical obligation to understand and include the client’s culture in treatment decision-making. Parenting norms in the United States are based upon the Western culture and do not apply to all cultural groups. This paper looks specifically at cultural differences in parenting practices among four cultural groups: African Americans, Asians, Hispanics, and European Americans. Implications for practice are provided for the counseling professional.

Standardized, Cost-Effective, And Repeatable Remote Sensing Methodology To Quantify Forested Resources In Texas, Daniel Unger, James Kroll, I-Kuai Hung, Jeffrey M. Williams, Dean W. Coble

Faculty Publications

A standardized remote sensing methodology was evaluated for its use in quantifying the forested resources of the state of Texas in a timely and cost-effective manner. Landsat data from 2002 were used to create a land cover base map encompassing a four-county study area in East Texas. Site-specific and non-site-specific accuracy assessments of the classified map indicate that overall the 2002 base map accuracy of 72.78% was within acceptable remote sensing standards for Landsat data and that forest cover types derived from 2002, 1987, and 1980 Landsat data were within 4.4, 0.5, and 7.4% agreement with Forest Inventory and Analysis …

Juvenile-To-Adult Antler Development In White-Tailed Deer In South Texas, James Kroll, Ben Koerth

Faculty Publications

Past studies using penned deer provide conflicting results on the age when reliable predictions about antler growth potential in white-tailed deer (Odocoileus virginianus) can be made. We captured wild whitetail males via aerial net gun on 12 ranches in 5 counties in south Texas, USA, from 1999 to 2007 to determine if a reliable juvenile-to-adult relationship in antler development existed. We individually marked and released captured animals at the trap site after we took antler and body measurements. We recaptured marked animals as possible in subsequent years or until we obtained final measurements after legal harvest. Amount of growth in …

Estimating Bobcat Abundance In East Texas Using Infrared-Triggered Cameras, Matthew E. Symmank, Christopher E. Comer, James C. Kroll

Faculty Publications

Reliable population estimation techniques for cryptic forest predators generally are lacking. Development of an efficient and reliable technique to estimate predator abundance directly would be a valuable tool for wildlife managers concerned with predator management. We evaluated the potential for camera survey techniques to provide abundance estimates for bobcats (Lynx rufus) in southeastern forest habitats. We also determined our ability to capture other forest carnivores photographically using these techniques. We used TrailMaster 1500 active infrared-triggered cameras to estimate abundance on a 1318-ha private land holding in eastern Texas. Camera stations were located along roads and wildlife travel corridors …

Growth And Condition Of American Alligators (Alligator Mississippiensis) In An Inland Wetland Of East Texas (Abstract), David T. Saalfeld, Warren C. Conway

Faculty Publications

Since removal from the endangered species list, Alligator mississippi-ensis (American Alligator) populations have recovered to allow regulated harvest throughout most of their range. However, harvest/population management is com- plicated since alligators are long-lived, reach sexual maturity at a minimum size rather than age, and experience differential growth rates depending on geographic location, growing season length, local environmental conditions, habitat, and population density. To date, few data exist on age, sex, growth, and size structure of inland alligator populations. In this study, alligator growth rate and condition were quantified through an intensive mark-recapture study conducted at Angelina-Neches/Dam B Wildlife Management …

Survival Of Longleaf And Loblolly Pines Planted At Two Spacings In An East Texas Bahiagrass Silvopasture, Brian P. Oswald, Kenneth W. Farrish, Micah-John Beierle

Faculty Publications

The practice of combining intensive timber and forage production on the same site, a silvopasture system, offers landowners the potential for diversification of income. The establishment of such a system in a pasture setting offers unique challenges compared with traditional timber or forage systems. In 2003, a silvopasture demonstration was established south of Carthage, Texas, in a pasture dominated by bahiagrass (Paspalum notatum). Four replications of treatments composed of open pasture, longleaf (Pinus palustris) and loblolly (Pinus taeda) pine planted at a traditional spacing, and longleaf and loblolly pine planted at a silvopasture spacing were established. Due to high mortality …

Watershed Forest Management Information System (Wfmis), Yanli Zhang, P. K. Barten

Faculty Publications

Maintenance of a sustainable clean water supply is critical for our future. However, watershed degradation is a common phenomenon around the world that leads to poor water quality. In order to protect water resources, the Watershed Forest Management Information System (WFMIS), was developed as an extension of ArcGIS® and is described in this paper. There are three submodels to address nonpoint source pollution mitigation, road system management, and silvicultural operations, respectively. The Watershed Management Priority Indices (WMPI) is a zoning approach to prioritize critical areas for conservation and restoration management. It meets the critical need to spatially differentiate land cover …

Multitemporal Analysis Using Landsat Thematic Mapper (Tm) Bands For Forest Cover Classification In East Texas, Jason Grogan, I-Kuai Hung, James Kroll

Faculty Publications

Land cover maps have been produced using satellite imagery to monitor forest resources since the launch of Landsat 1. Research has shown that stacking leaf-on and leaf-off imagery (combining two separate images into one image for processing) may improve classification accuracy. It is assumed that the combination of data will aid in differentiation between forest types. In this study we explored potential benefits of using multidate imagery versus single-date imagery for operational forest cover classification as part of an annual remote sensing forest inventory system. Landsat Thematic Mapper (TM) imagery was used to classify land cover into four classes. Six …

An Examination Of Accounting Majors' Ethical Decisions Before And After An Ethics Course Requirement, Violet Rogers, Aileen Smith

Faculty Publications

The increased focus on ethical decision making in the accounting profession has resulted in greater attention being paid to the education of future accountants. Texas is one of the states that requires a State Board approved university course in Accounting Ethics to be on the transcript of prospective CPA candidates. This study reports on research using senior/graduate level accounting majors at a Texas state university before the university course requirement and after the requirement. The survey presented four vignettes for the students to consider (i.e., 2 describe an ethical decision and 2 describe an unethical decision). Students were requested to …

Student Cheating Habits: A Predictor Of Workplace Deviance, Sharron M. Graves

Faculty Publications

Unethical behavior seems to be increasing exponentially in every facet of today's business environment. Property and production deviance are just two of the unethical behaviors exhibited by employees. According to a study conducted by S. Nonis and C. Swift (2001), students who engage in dishonest acts in college classes are more likely to engage in dishonest acts in the workplace. Research conducted during the three year period 2002 - 2005 by Don McCabe in conjunction with The Center for Academic Integrity at Duke University reveals that 70 percent of the 50,000 undergraduate students surveyed admit to some cheating (McCabe 2005). …

Becoming A Reading Specialist: Surveying The Possibilities, Judy A. Abbott, Cari R. Williams, Allison Swan-Dagen, Steven D. Rinehart

Faculty Publications

The terrain of graduate programs is changing, especially in light of preparing highly qualified teachers (NCLB, 2001) and standards-based accreditation (IRA, 2004a, NCATE, 2008). This changing terrain is noticed as many institutions of higher learning undergo program reviews through self-studies required by the institution, by state departments of education, by specialized professional associations, or by national accreditation entities. This project sought to explore the nature of reading specialists master’s programs by examining their websites in light of the shift towards standards-based accreditation of programs and the influence of federal legislation. Specific objectives for this descriptive study included: (a) reviewing master’s …

Sexual Selection And Alternative Reproductive Tactics In Cyprinodon Elegans, Jennifer M. Gumm

Faculty Publications

In systems with alternative reproductive tactics (ARTs), males have discrete behaviors and morphologies that allow them to optimize their reproductive success in relation to others in the population. Males with different phenotypes directly compete with one another for mates, providing unique opportunities for studying social interactions within a species. Using the Comanche Springs pupfish, Cyprinodonelegans, a species with three alternative reproductive tactics, I examine how male behaviors and social interactions influence the reproductive success of each tactic.

Previous studies suggest that large territorial males have high reproductive success, while satellite males and female mimics must intrude into territories in order …
