Identifying Grassland Cores In The Southeast: Relating Spatial Covariance To Avian Communities And Vegetation Structure, Lauren L. Berry
Identifying Grassland Cores In The Southeast: Relating Spatial Covariance To Avian Communities And Vegetation Structure, Lauren L. Berry
Graduate Theses and Dissertations
Globally, grasslands are declining in range, which is leading to a decline in grassland-dependent taxa. These declines can be attributed to a variety of issues, a major one being the encroachment of woody species into historic grasslands. There is a new framework for strategizing grassland management, referred to as “Defend the Core,” which calls for proactive management of intact grasslands, meaning conserving remaining grasslands by preventing woody encroachment in the first place. To successfully defend the core, it is imperative that we develop rapid methods to identify intact grassland cores for management priority. One method that can be used for …

Bilateral Asymmetry In The First Metacarpal: The Influence Of Handedness In Humans And Non-Human Primates, Lucyna A. Bowland
Graduate Theses and Dissertations
Muscle attachment sites (entheses) are often used to infer soft tissue anatomy and reconstruct behaviors within skeletal populations, but there remains a significant debate about whether and to what degree muscle use is accurately reflected in bony morphology. One of the most difficult problems in establishing the relationship between variation in muscle use and entheseal development is the inability to exclude a variety of external factors thought to influence enthesis development, including age, sex, body mass, and activity patterns. One way around this is to take advantage of the fact that humans are handed (preferentially using one hand over another, …

Vegetation Management During Establishment Of Native Grasses And Forb Plantings On Roadsides And Prairie Restoration, Rachel Woody-Pumford
Graduate Theses and Dissertations
North American prairies have been shrinking due to agricultural production, overgrazing, development of cities and towns, and climate change. However, integrated roadside vegetation management (IRVM) creates the opportunity to reestablish prairies along roadsides through planting native grasses and forbs. Utilizing postememergence (POST) herbicides registered for use along rights-of-way has the potential to remove invasive species and create space for newly establishing native grass and forb species. The use of clopyralid, florpyrauxifen-benzyl, metsulfuron, and quinclorac were found to be safe for use in plantings containing big bluestem (Andropogon gerardii Vitman) and butterfly milkweed (Asclepias tuberosa L.). However, florpyrauxifen-benzyl injured and stunted …

Production And Heat Unit Accumulation Tracking Of Long-Cane Blackberry In Controlled Environments, Leala Maree Machesney
Graduate Theses and Dissertations
Consumer demand for locally produced and high-quality blackberries is projected to increase. Most blackberry production is field-based, however, there is interest in producing blackberries using soilless culture and “long-cane” technique, where plants are grown in containers and trellised vertically. Soilless “long-cane” production of blackberries is viewed as a possible solution to the yield losses caused by soilborne pathogens such as Fusarium oxysporum, and methods of soil-borne pathogen control have become increasingly difficult with the ban of methyl bromide, a highly effective and widely used but environmentally harmful soil fumigant. Other reported benefits of soilless caneberry production include greater yields, increased …

We will utilize this new form of criticality to investigate the functional benefits that can be harnessed by operating near the critical point when performing working …
Turfgrass Soil Surfactants: Examining Active Ingredients, Application Strategies, And The Structure–Function Relationship In Sand-Based Putting Greens, Daniel Patrick O'Brien
Turfgrass Soil Surfactants: Examining Active Ingredients, Application Strategies, And The Structure–Function Relationship In Sand-Based Putting Greens, Daniel Patrick O'Brien
Graduate Theses and Dissertations
Soil surfactants, commonly referred to as wetting agents, are a leading water management strategy for golf courses. Non-ionic block copolymers are the most common type of turfgrass soil surfactant. However, differences in the registration process and labeling requirements allow soil surfactants to enter the marketplace accompanied by far-less data compared to other products used on golf courses. This has led to considerable confusion among golf course superintendents. Three primary sources of confusion are: (i) the widely-used marketing terminology of “penetrants” and “retainers” to classify wetting agents; (ii) active ingredients which in some cases are not disclosed at all; and (iii) …
