Vegetation Characteristics And Bird Communities Associated With Singing Painted Buntings In Northwest Arkansas, Lauren Kristina Thead

Graduate Theses and Dissertations

It has been shown that bird communities are affected by the species composition and physical structure of plant communities. Within avian communities, the bird species that are the most localized in distribution tend to be the most affected by habitat changes. My research analyzed plant and bird communities found with the Painted Bunting (Passerina ciris Linnaeus), a locally common but declining species throughout much of its range. First, I describe vegetation characteristics associated with singing male Painted Buntings in northwest Arkansas. I categorized field sites with singing male Painted Buntings as either managed for wildlife or unmanaged, based on land-use …

Laboratory Evaluation Of Efficacy Of Entomopathogenic Nematodes On Texas Leaf-Cutting Ants, Atta Texana, Pushpa Soti, Quentin Van Camp, Alexis Racelis

Biology Faculty Publications and Presentations

Entomopathogenic nematodes, a large group of nematodes specialized for parasitism of insects, have been used as classical biological control agents. The nematodes have potential to be used for insect pest management in organic gardening. We studied the potential impact of two entomopathogenic nematodes Steinerneima carpocapsae Weiser and Heterohabditis bacteriophora Poinar on the Texas leaf-cutting ant, Atta texana Buckley, that is considered a problematic agricultural pest in the southern US. We used a relatively large exposure rate of 250,000 nematodes per 10 ants in Petri dishes and monitored ant activity during a 96-hour time period. Results showed no significant differences among …

Breeding Bird Response To Post Oak Savanna Restoration Seven Years Post Management In Eastern Texas, Courtney Mcinnerney

Electronic Theses and Dissertations

Oak savannas were once an abundant vegetation type in the Midwestern United States that have now declined to <1% of their original distribution. Historically, natural disturbances such as periodic fire and grazing maintained oak savannas, but these have been reduced or eliminated, resulting in woody encroachment and subsequent habitat loss and degradation. In 2009-10, a baseline, pre-restoration study was completed to determine vegetation characteristics, breeding bird abundances, nest success, and nest site selection at the Gus Engeling Wildlife Management Area (GEWMA) in eastern Texas. The results showed a lack of savanna vegetation structure on degraded sites and few savanna or grassland obligate bird species. The goal of this study was to determine how breeding birds of oak savanna vegetation types in eastern Texas respond to restoration effects 7 years after initial management. Post-restoration surveys completed in 2016-17 showed a change in avian assemblages from a more woodland dominated community to grassland/savanna community. The presence and breeding of savanna obligate species dickcissel (Spiza americana) and lark sparrow (Chondestes grammacus) indicates that the restoration was successful. The presence of savanna species can be linked to the herbaceous vegetation that was restored to more closely resemble historic oak savanna structure and can quantify the success of restoration efforts.

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Alternative Feeding Strategies For Growing Cattle Grazing Endophyte-Infected Tall Fescue During The Summer, Kerri A. Johnson

MSU Graduate Theses

Two experiments were conducted to determine animal performance of alternative feeding strategies to heifers grazing endophyte-infected tall fescue during summer months. In Experiment 1, 40 Limousin heifers (261± 40kg initial BW) were stratified by weight and assigned to either a spring harvested tall fescue silage diet or grazing endophyte-infected tall fescue pasture with grain supplement having either natural or artificial shade for 80 days. In Experiment 2, 40 Limousin heifers (277 ± 44kg initial BW) were stratified by weight and assigned to either a traditional grain supplement or feather-meal supplement (rumen bypass arginine supplement) with natural or artificial shade while …

Reducing The Risk Of Invasive Pathogens To Wildlife Health In The United States, Edward E. Clark Jr., Marshall Meyers, David Eldon Starling, Brent Stewart, Nathan Stone, Gary Tabor, Jeffrey S. White

National Invasive Species Council

Call to Action

In keeping with action items 4.3.1 and 4.3.2 of the 2016–2018 National Invasive Species Council (NISC) Management Plan, the Wildlife Health Task Team of the Invasive Species Advisory Committee (ISAC) was charged with: 1) identifying the major areas of vulnerability to native wildlife from the introduction and spread of invasive pathogens, and 2) making recommendations to address these vulnerabilities, including through potential changes in statute, regulation, policy, or practice of the relevant agencies.

Considerations For The 2019–2021 Nisc Management Plan, Invasive Species Advisory Committee

National Invasive Species Council

The Issue

Efforts to prevent the importation of invasive species are insufficient to protect the United States. Nor are resources adequate for the eradication or control of invasive species that have already entered the country. There is a clear need for more effective coordination and collaboration among federal agencies and other entities to address gaps and inconsistencies in relevant statutes, regulations, agency authorities, as well as to improve and sustain access to the data needed to inform decisions and direct action

Putting The Pieces Together: Using Cattle To Build Soil For Crops, John Bell

Forage Symposium at the Kentucky Cattlemen’s Convention

Raising livestock AND crops is an important topic to me and perhaps one of the most significant keys to the success of Elmwood Stock Farm.

In some parts of the country either you ride a horse following livestock and are called a rancher or you ride steel, grow crops and are a farmer. Not both. Fortunately, I grew up in central Kentucky where, due to topography and climate, we did some of both. Few people had enough land to run enough cattle alone to make a living. Likewise, few farms laid in a manner that allowed someone to raise only …

Building Strong Nutrient Cycles In Kentucky's Pastures, Christopher D. Teutsch

Forage Symposium at the Kentucky Cattlemen’s Convention

Well managed grassland ecosystems are one of the most sustainable forms of agricultural production. Few nutrients are removed from properly managed grazing systems. Instead these nutrients are cycled within the grazing system. In addition, proper grazing management maintains a healthy and vigorous sod that protects the soil from erosion and increases rainfall infiltration. This article will discuss how to build and maintain strong nutrient cycles in Kentucky's pastures.

The Soil Is Alive!, Mark S. Coyne

Forage Symposium at the Kentucky Cattlemen’s Convention

Grab a handful of soil. . . . . What does it look like? What does it feel like? It may seem rather ordinary; but look closer. What are you holding in your hand? A mixture of minerals and air with some water and organic matter? Is that all? No. There's so much more to soil than that. For a soil scientist in general and a soil microbiologist in particular the soil is a living thing, a mixture of living and dead organisms in an organic/mineral matrix. Not every organism is identical, or as abundant, or does the same things, …

2017 Long-Term Summary Of Kentucky Forage Variety Trials, Gene L. Olson, S. Ray Smith, Christopher D. Teutsch

Forage Symposium at the Kentucky Cattlemen’s Convention

Forage crops occupy approximately 7 million acres in Kentucky. Forages provide a majority of the nutrition for beef, dairy, horse, goat, sheep, and wildlife in the state. In addition, forage crops play an environmentally friendly role in soil conservation, water quality, and air quality. There are over 60 forage species adapted to the climate and soil conditions of Kentucky. Only 10 to 12 of these species occupy the majority of the acreage, but within these species there is a tremendous variation in varieties. This publication was developed to provide a user-friendly guide to choosing the best variety for producers based …

Apple Pomace Consumption Favorably Alters Hepatic Lipid Metabolism In Young Female Sprague-Dawley Rats Fed A Western Diet, Roy Chris Skinner, Derek C. Warren, Soofie N. Lateef, Vagner A. Benedito, Janet C. Tou

Faculty & Staff Scholarship

Apple pomace, which is a waste byproduct of processing, is rich in several nutrients, particularly dietary fiber, indicating potential benefits for diseases that are attributed to poor diets, such as non-alcoholic fatty liver disease (NAFLD). NAFLD affects over 25% of United States population and is increasing in children. Increasing fruit consumption can influence NAFLD. The study objective was to replace calories in standard or Western diets with apple pomace to determine the effects on genes regulating hepatic lipid metabolism and on risk of NAFLD. Female Sprague-Dawley rats were randomly assigned (n = 8 rats/group) to isocaloric diets of AIN-93G and …

Conclusions

It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne

Human–Wildlife Interactions

The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …
