Revegetating Burned Arid Lands: Identifying Successful Native Species Using Trait And Competition Analysis: Final Report, Scott R. Abella

Fire Science

Species selection can make the difference between successful revegetation projects and costly failures. Candidate native species for revegetating burned arid lands in the southwestern United States must meet at least two criteria. These species must: (1) be competitive in postfire environments typically dominated by exotic grasses, and (2) be able to become established reliably by seeding or planting. In response to Manager’s Request Task 3 (reestablishment of native vegetation after fires on arid lands) in the 2006 JFS announcement for proposals, this research tackled the problem of selecting native species with the greatest chance of revegetation success by conducting synergistic …

Ecological Impacts Of Stream Bank Stabilization In A Great Plains River, Christopher M. Pracheil

School of Natural Resources: Dissertations, Theses, and Student Research

Reduced ecological complexity, decreased water quality, and accelerated stream bank erosion are common disturbances in rivers with agriculturally dominated watersheds. Massive bank failures, increased sediment loads, and decreased riverine habitat are current problems in the agriculturally dominated Cedar River of central Nebraska. In an effort to slow erosion and prevent further ecological degradation, 20 reach scale stream bank stabilization projects were installed on the Cedar River from 2001 to 2004. The objective of this study was to determine the impact of the Cedar River stream bank stabilization projects on the ecological conditions within the Cedar River. Stream bank erosion, suspended …

Lake Whatcom Bathymetry And Morphology, Robert J. Mitchell, Gerry Gabrisch, Robin A. Matthews

Lake Whatcom Bathymetry Report

Our objective for this study was to produce an accurate and usable bathymetric model and morphological data for Lake Whatcom to replace that produced by Lighthart et al. (1972). Herein, we summarize the techniques used to convert the 1999 the U. S. Bureau of Reclamation (BOR) hydrographic survey soundings and shoreline contours of Lake Whatcom into metric units and a Triangulated Irregular Network (TIN) bathymetry model. We also describe the procedures used to delineate the major lake basins and to calculate surface area, water volumes, and other morphometric parameters for each basin and the lake as a whole.

The Hydrology Of The Carroll Cave-Toronto Springs System: Identifying And Examining Source Mixing Through Dye Tracing, Geochemical Monitoring, Seepage Runs, And Statistical Methods, Benjamin Verlinden Miller

Masters Theses & Specialist Projects

In karst areas relationships between activities occurring on the surface and the overall health of the subsurface environment are often highly interconnected. However, the complex nature of karst flow systems can often make identification of these connections difficult. Carroll Cave, a large stream cave system located in the central Missouri Ozarks, is known for its biological and speleological significance. A dye tracing project to delineate a Carroll Cave recharge area through dye tracing has identified an area of 18.5 km2 which contributes water to the cave. The water from Thunder River within Carroll Cave was positively traced to eight springs …

Heavy Metal Concentrations In Water And Surface Sediments Of Wilgreen Lake, Madison County, Kentucky, Chad Von Gruenigen, Walter S. Borowski

EKU Faculty and Staff Scholarship

Heavy metal pollution remains problematic in natural waters, particularly for localities near plausible anthropogenic sources. We assayed the level of heavy metals in surface waters and within surface sediments of Wilgreen Lake, whose watershed drains industrial, urban, agricultural, and residential areas near Richmond, Kentucky. Water samples were treated according to Environmental Protection Agency (EPA) protocols and digested with trace-metal-grade nitric and hydrochloric acids. Sediment samples were collected with a grab sampler and digested using established EPA procedures with hydrogen peroxide and trace-metal-grade nitric acid. Both water samples and sediment samples were sent to Activation Laboratories for analysis, and were measured …

Policy And Science Of Geothermal Heat Use At Mcmurdo Station, Antarcrtica, Joe Alvine

Department of Environmental Studies: Undergraduate Student Theses

My thesis research project deals with the use of geothermal heat in Antarctica. Currently it is not allowed due to article 7 of the 1991 Protocol on Environmental Protection that placed a 50 moratorium on the exploitation of mineral resources. The US main base in Antarctica, McMurdo Station is currently powered by diesel generators that are inefficient, cause environmental damage, and is expensive to run. By exploring alternative energy options, McMurdo Station can reduce its dependence on non-renewable energy sources. By determining the geothermal potential of McMurdo Station, this project explores the possibilities and benefits that would occur with the …

Recent Legislation To Promote Wind Energy In Nebraska, Ryan Lemke

Department of Environmental Studies: Undergraduate Student Theses

Nebraska is currently ranked 4th in the nation for wind energy potential, but ranks low in actual wind power production. The lack of wind energy production could be the result of Nebraska’s unique public power districts that have eminent domain of distribution and retail sales of electricity in the State. Public Power districts are prohibited from receiving benefits of state and federal tax incentives for the development of wind farms, however some Nebraska power districts still pursue wind energy as a renewable source of energy.

Recent legislation changes, including the passing of laws LB629 and LB1048, have provided the State …

Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone

Department of Environmental Studies: Undergraduate Student Theses

The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …

Patterns Of Heavy Metal Concentration In Core Sediments, Wilgreen Lake, Madison County, Kentucky, Clint Mcmaine, Walter S. Borowski

EKU Faculty and Staff Scholarship

Elevated levels of cadmium, copper, lead, and nickel were found within the waters of Wilgreen Lake during a preliminary survey in 2007. Accumulation of heavy metals in freshwater systems is a known problem. Heavy metals enter the lake in the dissolved phase or adsorbed onto sediment particles and may be linked to industries within the lake’s watershed. Under certain geochemical conditions such as anoxia, heavy metals may detach from sediment particles and diffuse into overlying lake waters, causing a renewed influx of heavy metals into the ecosystem. We hypothesize that heavy metals should decrease in concentration upcore as a result …

Pesticide Use And Awareness On Pemba Island, Brooke Shorett, Lauren Crask

Independent Study Project (ISP) Collection

Use and awareness of pesticides by 301 farmers on Pemba Island, Tanzania, were surveyed, in order to assess practices and perceptions of pesticide use. Surveys were conducted in both peri-urban farms and rural farms, which were either irrigated or rain-fed. Results showed that while the overwhelming majority of farmers on irrigated fields used pesticides frequently, farmers located in rain-fed irrigation largely farmed without pesticides. Likewise, peri-urban farmers made use of pesticides far more than rural farmers. Of the farmers who did use pesticides, an average of Tsh 17,219 was spent annually on Rogol, Satunil, Dimethoate, Simithion, Thionex and Dursban. Most …

Stop Pummeling My Primates: Effects Of Land Use Change On Behaviors Of Papio Anubis Near Lake Manyara National Park In Mto Wa Mbu, Tanzania, Hannah Young

Independent Study Project (ISP) Collection

The ever-increasing human population means more land is required for housing and agricultural needs to sustain the growing population. This study involves a group of olive baboons living in and on the boundary of Lake Manyara National Park in Mto wa Mbu, Tanzania. They leave the park everyday and travel to surrounding areas. There are three different habitats near the baboons’ exit point of the park, a residential area with houses and some people, an undisturbed area without homes and residents, and an agricultural area, full of farms and the most densely populated area.

Extensive Aerosol Optical Properties And Aerosol Mass Related Measurements During Tramp/Texaqs 2006 – Implications For Pm Compliance And Planning, Monica Elizabeth Wright, Dean B. Atkinson, Luke Ziemba, Robert Griffin, Naruki Hiranuma, Sarah D. Brooks, James Flynn, Ryan Perna, Bernhard Rappenglück, Winston Luke, Paul Kelley

Chemistry Faculty Publications and Presentations

Extensive aerosol optical properties, particle size distributions, and Aerodyne quadrupole aerosol mass spectrometer measurements collected during TRAMP/TexAQS 2006 were examined in light of collocated meteorological and chemical measurements. Much of the evident variability in the observed aerosol-related air quality is due to changing synoptic meteorological situations that direct emissions from various sources to the TRAMP site near the center of the Houston-Galveston-Brazoria (HGB) metropolitan area. In this study, five distinct long-term periods have been identified. During each of these periods, observed aerosol properties have implications that are of interest to environmental quality management agencies. During three of the periods, long …

Eelgrass Distribution In The Great Bay Estuary For 2009 : Final Report, Frederick T. Short

PREP Reports & Publications

Eelgrass in the Great Bay Estuary in 2009 was once again present only in Great Bay itself and in Portsmouth Harbor. For the second year in a row, there was no eelgrass in Little Bay or in the Piscataqua River. In 2009, there was a continued loss of eelgrass biomass in Great Bay; there has been a 66.4% loss of biomass in Great Bay since 1996 and distribution is 30% less than in 1996. Although eelgrass distribution in Great Bay itself increased between 2008 and 2009, primarily due to continued expansion from natural seeding of bare areas, the Bay’s eelgrass …

Shoreline Evolution: Isle Of Wight, Virginia James River And Pagan River Shorelines, Donna A. Milligan, Kevin O'Brien, Christine Wilcox, C. Scott Hardaway Jr.

Reports

Shoreline evolution is the change in the shore zone through time. Along Chesapeake Bay’s estuarine shores, it is a process and response system. The processes at work include winds, waves, tides and currents which shape and modify coastlines by eroding, transporting and depositing sediments. The shore line is commonly plotted and measured to provide a rate of change, but it also is important to understand the geomorphic patterns of change. Shore analysis provides the basis to know how a particular coast has changed through time and how it might proceed in the future.

The purpose of this data report is …

The data inventory developed for the Shoreline Inventory is based on a three‑tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. Hand-held GPS units are used to log features observed in the field.
