Sensitivity Of The Meridional Transport In A 1.5-Layer Ocean Model To Localized Mass Sources, C. Herbaut, J. Sirven, J. Deshayes Jan 2006

Sensitivity Of The Meridional Transport In A 1.5-Layer Ocean Model To Localized Mass Sources, C. Herbaut, J. Sirven, J. Deshayes

Journal of Marine Research

The response of a 1.5-layer ocean model forced by localized stochastic mass sources is studied. The focus is on the sensitivity of the spectral characteristics of the meridional transport to the location and the extent of the source region. In all the experiments, performed in hemispheric and interhemispheric basins, the spectra show a peak at interannual time scale revealing the existence of an oscillation. The period of the oscillation is defined by the zonal extent of the forcing, whereas its amplitude is affected by its location. When the source region is located in the northwestern corner of the basin, the …

Aquatic Turning Performance Of Painted Turtles (Chrysemys Picta) And Functional Consequences Of A Rigid Body Design, Gabriel Rivera, Angela R.V. Rivera, Erin E. Dougherty, Richard W. Blob Jan 2006

Aquatic Turning Performance Of Painted Turtles (Chrysemys Picta) And Functional Consequences Of A Rigid Body Design, Gabriel Rivera, Angela R.V. Rivera, Erin E. Dougherty, Richard W. Blob

Publications

The ability to capture prey and avoid predation in aquatic habitats depends strongly on the ability to perform unsteady maneuvers (e.g. turns), which itself depends strongly on body flexibility. Two previous studies of turning performance in rigid-bodied taxa have found either high maneuverability or high agility, but not both. However, examinations of aquatic turning performance in rigid-bodied animals have had limited taxonomic scope and, as such, the effects of many body shapes and designs on aquatic maneuverability and agility have yet to be examined. Turtles represent the oldest extant lineage of rigid-bodied vertebrates and the only aquatic rigid-bodied tetrapods. We …

Long-Term Success Of Stump Sprouts In High-Graded Baldcypress-Water Tupelo Swamps In The Mississippi Delta, William Conner, Richard F. Keim, Jim L. Chambers, Melinda S. Hughes, Luben D. Dimov, Gary P. Shaffer, Emile S. Gardiner, John W. Day Jan 2006

Long-Term Success Of Stump Sprouts In High-Graded Baldcypress-Water Tupelo Swamps In The Mississippi Delta, William Conner, Richard F. Keim, Jim L. Chambers, Melinda S. Hughes, Luben D. Dimov, Gary P. Shaffer, Emile S. Gardiner, John W. Day

Publications

Regeneration of baldcypress (Taxodium distichum (L.) Rich.) and water tupelo (Nyssa aquatica L.) in swamps of the deltaic plain of the Mississippi River are of major importance for ecosystem sustainability and forest management in the context of regional hydrological changes. Water tupelo often forms prolific sprouts from cut stumps, and baldcypress is one of few conifers to produce stump sprouts capable of becoming full-grown trees. Previous studies have addressed early survival of baldcypress stump sprouts, but have not addressed the likelihood of sprouts becoming an important component of mature stands. We surveyed stands in southeastern Louisiana that were partially logged …

Structural Response Of Caribbean Dry Forests To Hurricane Winds: A Case Study From Guanica Forest, Puerto Rico, Skip Van Bloem, Ariel E. Lugo, Peter G. Murphy Jan 2006

Structural Response Of Caribbean Dry Forests To Hurricane Winds: A Case Study From Guanica Forest, Puerto Rico, Skip Van Bloem, Ariel E. Lugo, Peter G. Murphy

Publications

Tropical dry forests in the Caribbean have an uniquely short, shrubby structure with a high proportion of multiple-stemmed trees compared to dry forests elsewhere in the Neotropics. Previous studies have shown that this structure can arise without the loss of main stems from cutting, grazing, or other human intervention. The Caribbean has a high frequency of hurricanes, so wind may also influence forest stature. Furthermore, these forests also tend to grow on soils with low amounts of available phosphorus, which may also influence structure. The objective of this study was to assess the role of high winds in structuring dry …

Analyzing Dna Microarrays With Undergraduate Statisticians, Johanna S. Hardin, Laura Hoopes, Ryan Murphy '06 Jan 2006

Analyzing Dna Microarrays With Undergraduate Statisticians, Johanna S. Hardin, Laura Hoopes, Ryan Murphy '06

Pomona Faculty Publications and Research

With advances in technology, biologists have been saddled with high dimensional data that need modern statistical methodology for analysis. DNA microarrays are able to simultaneously measure thousands of genes (and the activity of those genes) in a single sample. Biologists use microarrays to trace connections between pathways or to identify all genes that respond to a signal. The statistical tools we usually teach our undergraduates are inadequate for analyzing thousands of measurements on tens of samples. The project materials include readings on microarrays as well as computer lab activities. The topics covered include image analysis, filtering and normalization techniques, and …

Yeast Through The Ages: A Statistical Analysis Of Genetic Changes In Aging Yeast, Alison Wise '05, Johanna S. Hardin, Laura Hoopes Jan 2006

Yeast Through The Ages: A Statistical Analysis Of Genetic Changes In Aging Yeast, Alison Wise '05, Johanna S. Hardin, Laura Hoopes

Pomona Faculty Publications and Research

Microarray technology allows for the expression levels of thousands of genes in a cell to be measured simultaneously. The technology provides great potential in the fields of biology and medicine, as the analysis of data obtained from microarray experiments gives insight into the roles of specific genes and the associated changes across experimental conditions (e.g., aging, mutation, radiation therapy, drug dosage). The application of statistical tools to microarray data can help make sense of the experiment and thereby advance genetic, biological, and medical research. Likewise, microarrays provide an exciting means through which to explore statistical techniques.

A Voice In The Wilderness, Michael Austin Jan 2006

A Voice In The Wilderness, Michael Austin

All USU Press Publications

In her writings, Terry Tempest Williams repeatedly invites us as readers into engagement and conversation with both her and her subject matter, whether it is nature or society, environment or art. From her evocation, in Desert Quartet: An Erotic Landscape, of an eroticism of place that defines erotic as "in relation," to the spiritual connectivity and familial bonds she explores in Refuge: An Unnatural History of Family and Place and the political engagement she urges in The Open Space of Democracy, much of her work is about relationship, connection, and community. Like much good writing, her books invite readers into …

From The Ground Up, Colleen K. Whitley Jan 2006

From The Ground Up, Colleen K. Whitley

All USU Press Publications

Mining had an enormous role, only partly measurable, in the history of Utah. Its multidimensional impact continues today. Economically, it made a major long-term contribution to the wealth, employment, and tax base of the state and stimulated a seemingly endless range of secondary businesses and enterprises. It helped shape the state's social history, determining the location, distribution, and composition of many communities and bringing transportation systems and a wide variety of institutions to them. It developed cultural diversity by drawing to Utah miners and families from otherwise underrepresented ethnic and national backgrounds. It ignited strife, particularly between labor and management, …

Livestock Grazing And The Utah Prairie Dog: Implications For Managing The Awapa, R. D. Elmore, Terry A. Messmer Jan 2006

Livestock Grazing And The Utah Prairie Dog: Implications For Managing The Awapa, R. D. Elmore, Terry A. Messmer

Wildland Resources Faculty Publications

The Utah prairie dog (Cynomys parvidens) is a federally listed species that occurs only in southwestern Utah. The Awapa Plateau in south-central Utah is one of three Utah prairie dog recovery areas. The prairie dog population in this area is below recovery goals established in 1991 by the U.S. Fish and Wildlife Service (USFWS). In 2002, the USFWS approved three Utah prairie dog mitigation banks on the Awapa Plateau. Little information exists regarding how these mitigation banks should be managed to optimize benefits for the species. Past research has suggested that management actions to reduce shrub canopy cover …

Mapping And Characterization Of 18-5 And 12-5, Genes Which Potentially Link The Rhoa Signaling Pathway To The Ecdysone Response, Samuel Fox Jan 2006

Mapping And Characterization Of 18-5 And 12-5, Genes Which Potentially Link The Rhoa Signaling Pathway To The Ecdysone Response, Samuel Fox

Electronic Theses and Dissertations

Systemic steroid hormone and intracellular signaling pathways are known to act cooperatively during the development of vertebrate and invertebrate epithelia. However, the mechanism of this interaction is poorly understood. Morphogenesis of Drosophila leg imaginal disc epithelia is regulated both by the steroid hormone 20-hydroxyecdysone (ecdysone) and the RhoA GTPase signaling pathway. Recent evidence suggests that these pathways act cooperatively to control imaginal disc morphogenesis. Thus, leg imaginal disc morphogenesis is an excellent system in which to study the interaction of steroid hormone and intracellular signaling pathways. We have identified mutations in three genes, 12-5, 18-5, and 31-6, with roles in …

Discrimination Of Automobile Carpet Fibers Using Multiple Analytical Techniques And The Subsequent Creation Of A Searchable Data, Derek Dorrien Jan 2006

Discrimination Of Automobile Carpet Fibers Using Multiple Analytical Techniques And The Subsequent Creation Of A Searchable Data, Derek Dorrien

Electronic Theses and Dissertations

Forensic fiber examination is an important part of trace evidence analysis. Fibers may be recovered from a crime scene that could link a particular suspect to the scene. Clothing fibers are most frequently encountered but automobile carpeting fibers may also be recovered. An understanding of the frequency of occurrence and the discrimination power of different analytical techniques is needed in order to better establish the evidentiary value of automobile carpet fiber evidence. Seventy-five automobile carpet fiber samples were analyzed using a series of techniques ranging from nondestructive to destructive. These techniques included polarized light microscopy, fluorescence microscopy, microspectrophotometry, Fourier-transform infrared …

Direct Control Of Cell Cycle Gene Expression By Proto-Oncogene Product Actr, And Its Autoregulation Underlies Its Transforming Activity, Maggie C. Louie, Alexey S. Revenko, June X. Zou, Jennifer Yao, Hong-Wu Chen Jan 2006

Direct Control Of Cell Cycle Gene Expression By Proto-Oncogene Product Actr, And Its Autoregulation Underlies Its Transforming Activity, Maggie C. Louie, Alexey S. Revenko, June X. Zou, Jennifer Yao, Hong-Wu Chen

Collected Faculty Scholarship

ACTR (also called AIB1 and SRC-3) was identified as a coactivator for nuclear receptors and is linked to multiple types of human cancer due to its frequent overexpression. However, the molecular mechanism of ACTR oncogenicity and its function independent of nuclear receptors remain to be defined. We demonstrate here that ACTR is required for both normal and malignant human cells to effectively enter S phase. RNA interference-mediated depletion and chromatin immunoprecipitation assays show that endogenous ACTR directly controls the expression of genes important for initiation of DNA replication, which include cdc6, cdc25A, MCM7, cyclin E, and Cdk2. Moreover, consistent with …

The Effect Of Carbon Revenues On The Rotation And Profitability Of Loblolly Pine Plantations In East Texas, Ching Hsun Huang, Gary D. Kronrad Jan 2006

The Effect Of Carbon Revenues On The Rotation And Profitability Of Loblolly Pine Plantations In East Texas, Ching Hsun Huang, Gary D. Kronrad

Faculty Publications

This study determined the profitability and financially optimal thinning and final harvest rotation of loblolly pine (Pinus taeda) managed exclusively for timber production or for dual products of timber production and carbon sequestration. The results suggest that 1) depending on landowner’s alternative rate of return, the inclusion of carbon revenues in forest management may shorten or prolong the optimal timber-carbon rotation length, compared to the optimal rotation that maximizes timber value only; 2) the effect of carbon revenues on the optimal rotation length and the percentage gain in soil expectation value is larger on low-productivity sites than on high-productivity sites, …

Faculty Publications

A generalized sigmoid growth function was used in this study to model site index (SI) for unmanaged or lowintensity managed loblolly pine (Pinus taeda, L.) and slash pine (Pinus elliottii, Engelm.) plantations in east Texas. Schnute's growth function was fit to 11 ,367 and 5,040 height-age observations of loblolly and slash pine, respectively. These data were collected over a 20-year period from unmanaged pine plantations located across the east Texas region as a part of the East Texas Pine Plantation Research Project (ETPPRP). The fit model was used to derive Sl equations (25-year index age). The Sl equations apply to …

Characteristics Of Bark Beetle Infestations In East Texas During A Period Of Low Southern Pine Beetle Activity, David L. Kulhavy

Faculty Publications

The species composition nf southern pine bark beetle infestations was examined in east Texas in 1979, A total of 545 infestations were located in thirteen 18,000 acresurvey blocks. Ips spp, were observed in 98.9 of ihe infestations, with black turpentine beetles, Dendrnclonus lerebrans Olivier, present in 42.4 % ofthe infestations. Southern pine beetles, D. fronlulis Zimmemiann. were only observed in 11 infestations (2.0%), and were less abundant than other bark beetle species in these infestations. Almost 80% of the infestations were associated with a recognizable pre-disposing factor (lightning, fire, etc.). Most Infestations were small (less than six trees), though infestations …

Spatial Autocorrelation And Pseudoreplication In Fire Ecology, Amanda L. Bataineh, Brian P. Oswald, Mohammad M. Bataineh, Daniel Unger, I-Kuai Hung, Daniel Scognamillo Jan 2006

Spatial Autocorrelation And Pseudoreplication In Fire Ecology, Amanda L. Bataineh, Brian P. Oswald, Mohammad M. Bataineh, Daniel Unger, I-Kuai Hung, Daniel Scognamillo

Faculty Publications

Fire ecologists face many challenges regarding the statistical analyses of their studies. Hurlbert (1984) brought the problem of pseudoreplication to the scientific community’s attention in the mid 1980’s. Now, there is a new issue in the form of spatial autocorrelation. Spatial autocorrelation, if present, violates the traditional statistical assumption of observational independence. What, if anything, can the fire ecology community do about this new problem? An understanding of spatial autocorrelation, and knowledge of available methods used to reduce the effect of spatial autocorrelation and pseudoreplication will greatly assist fire ecology researchers.

Population Trends Of Red-Cockaded Woodpeckers In Texas, Richard N. Conner, Daniel Saenz, D. Craig Rudolph Jan 2006

Population Trends Of Red-Cockaded Woodpeckers In Texas, Richard N. Conner, Daniel Saenz, D. Craig Rudolph

Faculty Publications

We tracked population trends of Red-cockaded Woodpeckers (Picoides borealis) in eastern Texas from 1983 through 2004. After declining precipitously during the 1980s, woodpecker population trends on federal lands (National Forests and Grasslands in Texas, but excluding the Big Thicket National Preserve) increased between 1990 and 2000, and have been stable to slightly decreasing over the past four years. Litigation against the U.S. Forest Service in the mid 1980s reversed a severe population decline, whereas litigation during the past 8 years hampered recovery efforts for the Red-cockaded Woodpecker. Red-cockaded Woodpecker populations on private and State of Texas lands have steadily declined …

Winter Food Habits And Preferences Of Northern Bobwhites In East Texas, Donald R. Dietz, R. Montague Whiting Jr., Nancy E. Koerth Jan 2006

Winter Food Habits And Preferences Of Northern Bobwhites In East Texas, Donald R. Dietz, R. Montague Whiting Jr., Nancy E. Koerth

Faculty Publications

During late winter, 1994 and 1995, we investigated food habits and preferences of northern bobwhites (Colinus virginianus; hereafter, bobwhites) collected on forested lands in east Texas. Crops for bobwhites were collected from areas under 3 management regimes, namely intensively managed for bobwhites (QMA) (i.e., tree basal area reduced, annually burned, numerous multi-stage food plots, etc.), extensively managed for timber and wildlife (NBS) (i.e., burned every 3-5 years, scattered 2-stage food plots with corn feeders), and unmanaged for wildlife (i.e., burned every 5-7 years). With years pooled, partridge pea (Cassia fasciculata), Hercules club (Zanthoxylum clava-herculis), and pine (Pinus spp.) seeds, and …

Faculty Publications

The most conspicuous biological invasions in terrestrial ecosystems have been by exotic plants, insects and vertebrates. Invasions by exotic earthworms, although not as well studied, may be increasing with global commerce in agriculture, waste management and bioremediation. A number of cases has documented where invasive earthworms have caused significant changes in soil profiles, nutrient and organic matter dynamics, other soil organisms or plant communities. Most of these cases are in areas that have been disturbed (e.g., agricultural systems) or were previously devoid of earthworms (e.g., north of Pleistocene glacial margins). It is not clear that such effects are common in …

Predation And Cathemerality. Comparing The Impact Of Predators On The Activity Patterns Of Lemurids And Ceboids., Ian C. Colquhoun Jan 2006

Predation And Cathemerality. Comparing The Impact Of Predators On The Activity Patterns Of Lemurids And Ceboids., Ian C. Colquhoun

Anthropology Publications

The removal, or absence, of predatory species could be a contributing proximate factor to the rise of primate cathemerality. But predators themselves can also be cathemeral, so cathemerality could well be an evolutionary stable strategy. From a comparative perspective, it appears that the effect of predatory species cannot provide a unitary explanation for cathemerality. Varying distributions and population densities of predators, especially raptors, may be key factors in owl monkey (Aotus) cathemerality, but temperature and lunar cycle variation have also been implicated. In Madagascar, while raptors are potential predators of lemur species, the cathemerality of Eulemur species coincides with that …

A Proteomics Approach Towards Biomarkers Of Preeclampsia, Aaron T. Booy Jan 2006

A Proteomics Approach Towards Biomarkers Of Preeclampsia, Aaron T. Booy

Digitized Theses

Preeclampsia (PE) is a pregnancy specific disease that affects 5-8% of all pregnancies worldwide, and is one of the leading causes of maternal and neonatal morbidity and mortality. While the cause of PE is still unknown, clinical evidence unequivocally points to placenta as the site of pathophysiology. It is widely accepted that impaired cellular invasion during placental development and a lack of proper development of the decidual spiral arteries account for the development of PE. Despite considerable research, the factor(s) that ultimately cause PE have not been fully characterized. Through the use of 2D SDS-PAGE and LC MS∕MS, control and …

Analysis Of Reaction Time Experiment Data Using Point Process Techniques, Jennifer Lea Asimit Jan 2006

Analysis Of Reaction Time Experiment Data Using Point Process Techniques, Jennifer Lea Asimit

Digitized Theses

Point process data with a latent or hidden component arise in a variety of research fields. Examples include reaction time, forest fires, seismology, and transactional data. We develop statistical methodology that can be applied to point process data with a latent component. The methodology is applied to data from a number of reaction time (RT) experiments. Reaction time experiments have been of interest to psychophysicists for more than a century. A reason for this interest lies in the fact that the time taken to perform a task indicates the complexity of the operations occurring in the brain. We study three …

Characterization Of Ntgras1, A Novel Stress-Induced Member Of The Gras Family, Beatrix E. Czikkel Jan 2006

Characterization Of Ntgras1, A Novel Stress-Induced Member Of The Gras Family, Beatrix E. Czikkel

Digitized Theses

The focus of this project is the initial characterization of a recently isolated stress-induced gene from tobacco (Nicotiana tobacum}. Analysis of the predicted amino acid sequence of this gene shows that it shares the highly conserved carboxy-terminal motifs common to members of the GRAS family of proteins. Because of this similarity, the gene is denoted NtGRAS1. Transcript abundance was found to be induced in tobacco BY-2 cells by antimycin A, H2O2, salicylic acid, L-cysteine and sodium nitroprusside. All treatments were found to raise intracellular reactive oxygen levels. Inhibition of protein kinase and phosphatase action revealed that reversible phosphorylation is required …
