Utilization Of The Hunt Trap Method To Investigate A Small Mammal Community In An Upland Pine Stand, Leo Montano

Undergraduate Research Conference

Small mammals are strong and informative biological indicators of forest ecosystems. Populations are responsible for shaping successional patterns through their diets, behaviors, and contributions to other ecological communities.

Knowledge of community metrics within southern yellow pine forests under varying production and disturbance regimes can be valuable in understanding pine production impacts on biodiversity.

The objective of this study was to investigate species richness, time to detection, and activity patterns of the small mammal community in an upland pine stand utilizing the Hunt Trap Method.

Landscapes Are Cornerstones Of Sustainability Programs, Don Spence

Sustainability Conference

Typical American landscapes are not sustainable in an economic or biological framework. The essence of the idea of sustainable growth and development are centered on the idea that those activities are not degrading natural resources or that they are outstrip budgets. A significant piece of any sustainable management plan is tied to how we manage our landscapes, how we use plants; specifically, how much grass there is, and how many native plants there are. Sustainable landscapes should require less chemical and financial inputs, which in the end, saves money and increases the biological value of the land and creates a …

Towards The Identification Of The Soil Fungal Microbiome Community Associated With Longleaf Pine, Joshua Inneh, Grace Krueger, Ian Thomasson, Fletcher Moon, Geoffrey Eger

Symposium of Student Scholars

This project is part of a larger study looking at the restoration of the Longleaf Pine (LLP) ecosystem in certain Wildlife Management Areas (WMA) in Northwest Georgia. Our long-term aim is to look for potential associations between the aboveground and belowground community structures as the complex system of feedback mechanisms between the soil microbiome, the rhizosphere, and the plant communities is not yet understood.

Soil samples were collected from a total of six plots in the Sheffield WMA located in Paulding County. The samples were collected from north or south facing hillside plots except for in the savanna sites (an …

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 …

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 …

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 …

Responses Of Problematic Algae To Copper-Based Algaecide, Aaron Slevin, Clayton Rushing, James Cunningham, Joseph Watkins, Michael Deguenther

Undergraduate Research Conference

Eutrophication is the process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates. These typically promote excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of available oxygen, causing the death of other organisms, such as fish. Eutrophication is a natural, slow-aging process for a water body, but human activity greatly speeds up the process (USGS.gov). Golf Courses are often fertilized numerous times a year and can be major problem in fertilizer runoff in ponds surrounding the course. In east …

Seedling Uptake And Fate Of Soil-Applied Capsaicin, A Potential Browse Deterrent, Carmen K. Dobbs, Joshua L Sloan, Douglass F. Jacobs

The Summer Undergraduate Research Fellowship (SURF) Symposium

Seedling damage due to browse constitutes a major challenge to afforestation and reforestation efforts in the Central Hardwood Forest region of the USA. Many efforts have been made to deter herbivores, but the costs, implementation methods, and relative ineffectiveness of existing mitigation options often preclude operational implementation. An alternate means of deterring wildlife browse is capsaicin, a hot pepper concentrate, which has been reported to decrease herbivory of tree seedlings and is available in a controlled-release form designed to act systemically following application to the soil and subsequent plant uptake. However, the degree to which seedlings are capable of absorbing …

Development Of Transgenic North American White Ash (Fraxinus Americana) Expressing A Bacillus Thuringiensis Protein For Management Of The Emerald Ash Borer, Eric A. Dean, Paula M. Pijut Phd., Micah E. Stevens

The Summer Undergraduate Research Fellowship (SURF) Symposium

White ash (WA), Fraxinus americana, is an integral part of the hardwood forest ecosystem. Economically, WA provides wood for important products such as baseball bats, tool handles, and hardwood flooring. Ecologically WA provides cover and mast to support wildlife. The emerald ash borer (EAB) is a significant threat to all ash species because of a lack of native resistance in North American ash trees, its rapid spread, and the ineffectiveness and expense of control measures. EAB is a non-native beetle that consumes tree vascular tissue while in the larval stage. The development of an Agrobacterium-mediated transformation protocol may …

Surveys Of Southern Flying Squirrel Activity Following Timber Harvest In Southern Indiana, Joseph W. Eisinger, Elizabeth A. Flaherty, Stephanie E. Trapp

The Summer Undergraduate Research Fellowship (SURF) Symposium

Southern flying squirrels (Glaucomys volans) are gliding small mammals that are ecologically important seed dispersers and prey species across their wide range, which extends from southern Canada to Central America. Because of their reliance on forest structure for efficient movement and on forest composition for hard mast production to provide winter food items, habitat use by G. volans may be impacted by timber harvest. Responses of G. volans to timber harvests remains understudied throughout their range, and studies are especially lacking within the Central Hardwoods Region that includes Indiana. Our study in the Hardwood Ecosystem Experiment (HEE) in southern Indiana …

National Park Service Cave Ecology Inventory And Monitoring Framework, Gretchen M. Baker, Steven J. Taylor, Shawn Thomas, Rick Olson, Kathy Lavoie, Marie Denn, Steven Thomas, Hazel Barton, Kurt Helf, Rene Ohms, Joel Despain, Jim Kennedy, David Larson

National Cave and Karst Management Symposium 2013

A team developed the Cave Ecology Inventory and Monitoring Framework for National Park Service (NPS) units. It contains information for NPS cave managers across the United States to determine how to inventory and monitor cave ecology. Due to the wide geographical scope of NPS caves and their many different types, the document does not prescribe exact protocols. Instead, it provides guidance for what types of inventory and monitoring are possible, a framework for deciding how to prioritize inventory and monitoring activities, and references to specific protocols that are already in place at NPS cave parks.

Texas Black Bears, Alexandria Bryant

Undergraduate Research Conference

One way to promote conservation efforts in an area is to bring awareness of the connections our society has with the animal that is under threat. Black Bears were once abundant throughout Texas, but through hunting and habitat loss, the bears had been eliminated from Texas by the 1950s. The placing of the Louisiana subspecies as threatened under The Federal Endangered Species Act in 1922 allowed populations to recover in Louisiana, and there have been several sightings in East Texas since. The face of Texas has been forever altered byt the presence of black bears. From the forests of East …

The Effects Of Food Quality On Preference And Incurred Risk In White-Tailed Deer (Odocoileus Virginianus), Travis Perlman, Jacob Stanton

Undergraduate Research Conference

An observational study was concluded in Nacogdoches County, Texas, to determine if free-range white-tailed deer (Odocoileus virginianus) could assess forage value. Multiple parameters were recorded to determine if individuals were willing to incur hight levels of risk as they sought to maximize their fitness, through dietary selection. Our results indicated that individuals were willing to incur higher levels of risk, in order to attain higher quality food items.
