Microbial Abundance And The Pattern Of Escherichia Coli Antibiotic Sensitivity And Resistance In Deer Creek And The Potential Impact Of A Veterinarian Hospital’S Input, Sarah Boxer, Tim Gsell

Research Days

The gram-negative bacteria, E. coli, is an indicator of fecal input for both point and non-point source origin. The veterinarian hospital located on Deer Creek may contribute to high antibiotic levels, which are known to select for resistant strains of bacteria living in impacted waters. The water running north of the veterinarian hospital was considered potentially antibiotic influenced as it was downstream of the site. The origin of the stream and sites upstream from the hospital were considered influent water. Sediments were also collected from these sites to determine if more long term resident E. coli were present with elevated …

Assessment Of Soil Particle Size Distribution Under Four Land Covers In Nachusa Grasslands Of Northern Illinois, Reni Truhtcheva Owikoti, Diana Acosta, Markeia Scruggs, Xiaoyong Chen

Research Days

Soil particle composition is one of the main physical properties of soil that affects soil fertility and quality. The fractal dimension of soil particle size distribution (PSD) can be used to quantitatively evaluate the particle composition of soils. Land cover change with corresponding management practices is recognized as one important driving force affecting soil PSD alterations. The objective of this project was to determine the changes in soil PSD under four plant covers (Woodland, Wetland, Prairie, and Savannah) at the Nachusa Grasslands in North Illinois. The soil PSD was determined by their settling rates in an aqueous solution using hydrometer. …

Soil Responses to One-Season Winter Cover Crops

McKenna Morgan and I. P. Handayani

Hutson School of Agriculture Murray State University, KY, USA

Abstract

In regions like western Kentucky where wooded lots are common there is a growing interest in how to utilize them so that land profits can be maximized. The frequently poor soils in wooded areas due to erosion and lack of ground cover vegetation often cause complications in the creation of pasture areas. Therefore, the objective of this study was to assess the effect of growing winter cover crops on soils to prepare for pasture systems in the …

Ponderosa Pine Seedling Physiology After Severe Wildfire: Does It Take A Forest To Make A Forest?, Lauren Bansbach

Shared Knowledge Conference

Ponderosa pine forests are an iconic ecosystem of western North America and provide numerous ecological, economic, and cultural benefits. Historically, these forests experienced regular surface fires that left most large, mature trees surviving. However, suppression of wildfires along with a warming climate have led to catastrophic tree-killing fires that result in vast areas (>200 mi2) dominated by shrubs and grasses. Because of limited survival of tree seedlings in these post-fire habitats, it remains unknown whether ponderosa pines can successfully recolonize severely burned landscapes. Without a mature tree canopy to provide periodic shade, seedlings experience hotter, drier conditions and likely …

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …

Effect Of Spatial Influence On Endophyte Diversity Within Alnus Rubra, Sebastian L. Singleton

Student Research Symposium

Red alders (Alnus rubra) of the Pacific Northwest are characterized as actinorhizal dicotyledons; plants that possess that ability to form symbiotic relationships with endophytic organisms, which result in nitrogen-fixing nodules. In Alders of the order Fagales, such a symbiotic relationship with Frankia bacteria allows these plants to play crucial environmental roles as pioneer species able to colonize and enrich nutrient-deficient soils. This ability has a major impact on ecological succession by enabling other species to establish. Although inoculation with frankia bacteria is known to increase symbiotic nitrogen fixation capabilities of actinorhizal plants, whether they could confer the same benefit to …

Influence Of Chinese Tallow Infestation On Winter Bird Community Along Lanana Creek Basin, Kelli Bashaw, Christopher E. Comer

Undergraduate Research Conference

Exotic invasive plant species are among the greatest threats to biodiversity and persistence of rare wildlife species in the United States. These plants compete with native plants, causing extinctions or severe reductions in native populations. They may also affect wildlife through loss of preferred food items or changes in vegetation structure. Chinese tallow tree (Triadeca sebifera) is one of the most important and widespread exotic plants in the Southeast. Although impacts of Chinese tallow on vegetation communities are well studied, impacts on native wildlife are less well understood. This study explored the interaction between native wildlife and Chinese tallow infestation …
