Tillage, Cover Crop And Nitrogen Fertilization Effects On Soil Microbial Carbon Dynamics Under Long-Term Cotton Production, 2014 University of Tennessee - Knoxville
Tillage, Cover Crop And Nitrogen Fertilization Effects On Soil Microbial Carbon Dynamics Under Long-Term Cotton Production, Molefi Jacob Mpheshea
Effective soil management requires a deeper understanding of how internal soil carbon (C) works. This is vital as cycling is tightly linked with nutrient cycling processes. This study evaluated the effect of agronomic practices including tillage (no-till and tilled), cover crops (no cover, hairy vetch - Vicia villosa L, and winter wheat - Triticum aestivum. L ) and different N fertilizer rates ( 0, 34 and 101 kg N per hectare ) on soil microbial C dynamics as measured by soil microbial biomass C (SMBC) along with soil microbial respiration over the 2013 cotton growing season at Jackson, West Tennessee. The study was set as ...
Northern Bobwhite (Colinus Virginianus) Habitat Selection On A Reclaimed Surface Mine In Western Kentucky, 2014 University of Tennessee - Knoxville
Northern Bobwhite (Colinus Virginianus) Habitat Selection On A Reclaimed Surface Mine In Western Kentucky, Ashley Marie Unger
Reclaimed mines present an opportunity to provide large tracts of habitat for northern bobwhite (Colinus virginianus). Reclaimed mine sites are commonly planted to non–native species, including sericea lespedeza (Lespedeza cuneata) and tall fescue (Schedonorus phoenix), which can inhibit growth of more desirable plant species and limit favorable structure for bobwhite. Although bobwhite are found on reclaimed mine sites, there have been no studies documenting how bobwhites use various vegetation types common to reclaimed mine land. Habitat use studies can provide information on how bobwhite select vegetation types on these landscapes and help direct future management decisions. We trapped and ...

Un Cuento Satírico En Medio Del Debate Sobre El Darwinismo En México, 2014 University of South Florida
Un Cuento Satírico En Medio Del Debate Sobre El Darwinismo En México, Miguel A. Fernández Delgado Mafd
Alambique: Revista académica de ciencia ficción y fantasia / Jornal acadêmico de ficção científica e fantasía
Charles Darwin's theory of biological evolution of species was accepted or rejected by Mexican scientists, including Gabino Barreda, representative of Comte's philosophy. It was also included by Justo Sierra in a history book for the Escuela Nacional Preparatoria, a decision which raised a lot of criticism from conservative groups. It is also discussed the implications of social Darwinism in the early Twentieth Century Mexico. The document we offer is a satire published in those years, which resembles the tone of Swift's Gulliver Travels.
Aquaponics And Basil Plant Density, 2014 CSU-Sacramento
Aquaponics And Basil Plant Density, Danika L. Macmaster, Brook Murphy, Dudley Burton
STAR (STEM Teacher and Researcher) Program Posters
Aquaponics is the use of water from a fish tank to provide nutrients to plants in a soil-less environment. The rocks cultivate the bacteria that turns the ammonia into nitrates that the plants need, and the plant bed functions as a filter for the fish tank. In this study, with the guidance of Doctor Dudley Burton, Doctor Brook Murphy, we researched the optimal plant density for basil in an Aquaponics system. We attempted to control or measure all the other variables to consider, as to isolate the variable of distance between plants. The water flow was spread through the plant ...

The question of whether there is or was life on Mars has been one of the most pivotal since Schiaparellis’ telescopic observations of the red planet. With the advent of the space age, this question can be addressed directly by exploring the surface of Mars and by bringing samples to Earth for analysis. The latter, however, is not free of problems. Life can be found virtually everywhere on Earth. Hence the potential for contaminating the Mars samples and compromising their scientiﬁc integrity is not negligible. Conversely, if life is present in samples from Mars, this may represent a potential source ...

Soil Moisture And Temperature Conditions Related To Cheatgrass Establishment Failure, 2014 Utah State University
Soil Moisture And Temperature Conditions Related To Cheatgrass Establishment Failure, Lauren Ducas
All Graduate Plan B and other Reports
Cheatgrass, a widespread invasive plant, has taken over many rangelands in the Intermountain West. Restoration efforts have not met with much success. Early in cheatgrass’ growth period, if air temperatures fall too low and soils too dry, growth may be disrupted to the point of death of the cheatgrass plants. In this case, cheatgrass stands may revert to bare ground, providing opportunities for other invasive plants to establish, or possible restoration of native perennials. We conducted a computer modeling and observational field study to determine if air temperature and soil moisture conditions below its tolerance are associated with failure of ...

Death Acceptance In Widowhood, 2014 University of Kentucky
Death Acceptance In Widowhood, Staci Ernsberger
Theses and Dissertations--Family Sciences
Death is a universal event that all living things experience. Older adults, in particular, are more mindful of death than younger generations because of their proximity and increased exposure to it. In addition, thoughts of one’s own death often increase with the death of a spouse. Previous research has explored the role of social support in death acceptance and the effect of previous marital satisfaction on a widow’s well-being. However, there is a lack of research regarding the experience of a widow’s personal death acceptance relative to spousal death acceptance and marital satisfaction. This phenomenological study aims ...
Modern Cavemen? Stereotypes And Reality Of The Ancestral Health Movement, 2013 Princeton University
Modern Cavemen? Stereotypes And Reality Of The Ancestral Health Movement, David B. Schwartz, Hamilton M. Stapell
Journal of Evolution and Health
Both academic and popular interest in the ancestral health movement, or “paleo” lifestyle, has grown rapidly in recent years. More people than ever are joining the movement, and more books and articles are being published on the topic. Media coverage and certain societal preconceptions of the movement have also increased. More often than not, followers of a paleo lifestyle are thought to be “modern cavemen”: athletic, single, meat-eating, young, white, and male. To test whether or not these stereotypes are true, the authors of the present study created the first large, academic survey (N = 3,967) of the ancestral health ...
Population Dynamics Of The Louisiana Black Bear In The Upper Atchafalaya River Basin, 2013 University of Tennessee - Knoxville
Population Dynamics Of The Louisiana Black Bear In The Upper Atchafalaya River Basin, Kaitlin Christine O'Connell
The Louisiana black bear (Ursus americanus luteolus) is listed as Threatened under the Endangered Species Act as a result of habitat loss and human-related mortality. Two of the 3 sub-populations must be viable for delisting to occur. I collected hair samples from 2010 to 2012 in a DNA mark-recapture study to augment data collected from 2007 to 2009 in the Upper Atchafalaya River Basin (UARB) to estimate abundance (N), growth rate (λ), and apparent survival rates (φ) to ultimately be used in a population viability analysis. In addition, I evaluated the effects of the opening of the Morganza Spillway in ...

Common Core 4th Grade Environmental Science Lesson Plans For California Teachers, Gillian Schoenfeld
Natural Resources Management and Environmental Sciences
This project and its analyses were conducted to assist California fourth grade elementary school teachers in adjusting to teaching Common Core standards and science curriculum in their classrooms. The project included the creation of lesson plans, which could be utilized throughout the state of California.
As the Common Core standards, California’s Next Generation Science Standards for K- 12, were just proposed in June of 2013, these lesson plans would help teachers update their lessons and provide them materials and concepts of how to do so. These lessons provide higher-order thinking for students, which is the whole concept of the ...
Emerald Ash Borer Adult Feeding Behavior And Ash Tree Management Decision Modeling: Relationships Between Pest And Host Tolerance Gradients, 2013 Indiana University - Purdue University Fort Wayne
Emerald Ash Borer Adult Feeding Behavior And Ash Tree Management Decision Modeling: Relationships Between Pest And Host Tolerance Gradients, Rachel E. Hunnicutt
Emerald ash borer (Agrilus planipennis Fairmaire, Buprestidae) is an invasive pest, introduced from Asia that attacks North American ash trees (Fraxinus spp.). Trees often die from attack by emerald ash borer, whether they are growing vigorously or not, within a few years. Some ash do not succumb as easily to attack as other individuals, despite being within the same species. After emergence, both adult emerald ash borer males and females require maturation feeding, which may assist in suitable host finding for subsequent oviposition. I compared the amount of leaf area consumed by emerald ash borer adults between leaves from trees ...

Case Study: The Parkinson's Experience, 2013 Western Oregon University
Case Study: The Parkinson's Experience, Scott A. Thurman
Previous research has extensively studied individual components of Parkinson’s by studying the disease but thus far does not address the comprehensive impacts and obstacles of life with Parkinson’s. The common experiences of Parkinson’s can offer insight as to how provide better care by addressing multiple domains in a person’s life. This hypothetical case study highlights commonalities shared by those with Parkinson’s that spans across social, emotional and biological aspects of life. Possible treatment strategies are discussed concerning the impacts of fatigue, social isolation, increased burdens of care, and family dynamics in order to offer insight ...
Rutting Behavior And Factors Influencing Vehicle Collisions Of White-Tailed Deer In Middle Tennessee, 2013 University of Tennessee, Knoxville
Rutting Behavior And Factors Influencing Vehicle Collisions Of White-Tailed Deer In Middle Tennessee, Peyton Seth Basinger
White-tailed deer (Odocoileus virginianus; deer) and human populations have expanded, and as a result, deer-vehicle collisions (DVCs) have become a primary concern. In particular, Arnold Air Force Base (AAFB) in Tullahoma, Tennessee, USA has had extensive problems with DVCs and has struggled to incorporate effective mitigation strategies. To address this issue, I initiated a study on AAFB to investigate deer behavior and factors increasing the likelihood of DVCs.
DVCs typically increase with peaks in deer activity during the breeding season (rut). I deployed GPS-ARGOS satellite collars on 10 adult males and 10 females during the summer of 2010. I investigated ...
Amphibian Occupancy And Functional Connectivity Of Restored Wetlands In The Missouri River Floodplain, 2013 University of Nebraska-Lincoln
Amphibian Occupancy And Functional Connectivity Of Restored Wetlands In The Missouri River Floodplain, Michelle L. Hellman
Dissertations & Theses in Natural Resources
Wetland decline may threaten many taxa including shorebirds, amphibians, and fish. As agencies increase restoration of wetland habitat, monitoring is crucial to inform the process. Permeable skin sensitive to water quality and biphasic life histories requiring both terrestrial and aquatic habitat make amphibians good indicators of wetland health. I modeled amphibian occupancy in restored Missouri River bends to determine habitat characteristics associated with the presence of amphibians.
Occupancy modeling acknowledges imperfect detection and allows the inclusion of detection covariates. To assess detection I examined two methods currently used to assess anuran occupancy in wetlands, aural anuran surveys and tadpole dip-netting ...
Governing Occupation Through Constructions Of Risk: The Case Of The Aging Driver, 2013 The University of Western Ontario
Governing Occupation Through Constructions Of Risk: The Case Of The Aging Driver, Silke Dennhardt
University of Western Ontario - Electronic Thesis and Dissertation Repository
Risk and risk-management have become increasingly pervasive features of modern society and governmentality scholars have highlighted various ways risk discourses are taken up to govern citizens and their everyday conduct. Thus, attending to risk is imperative to advance an understanding of how everyday occupation is shaped and governed within contemporary society. Within this study, the example of driving in later life is drawn upon to address two objectives: 1. to advance the understanding of how risk is taken up to govern everyday occupation, and 2. to explicate how risk is taken up in discourses to constitute particular subjectivities and their ...
