The Effect Of Prescribed Burns On Cation Exchange Capacity In An Oak Savanna, Christopher Michael Gentry

All-Inclusive List of Electronic Theses and Dissertations

The Indiana Department of Natural Resources estimates that fire-maintained, tallgrass savannas once covered approximately 15% oflndiana. During the 1800's, settlers cleared savannas for their rich soils, which are well suited for agricultural use, and fire was suppressed from the remaining savannas because of the threat to farmland. Today, prescribed bums are being used in savannas as a management tool to reduce competition from non-native species, encourage community density, and promote patch dynamics. This research examines how fire affects Cation Exchange Capacity (CEC) in post fire soil samples. CEC is an important soil characteristic that helps to describe soil fertility. With …

Status And Trends In Water Quality And Living Resources In The Virginia Chesapeake Bay: York River (1985-2002), Daniel M. Dauer, Harold G. Marshall, John R. Donat, Michael F. Lane, Suzanne Doughten, Frederick A. Hoffman

Status and Trends for Virginia Chesapeake Bay

The Virginia Chesapeake Bay and its tidal tributaries continue to show some environmental trends indicating progress toward restoration of a more balanced and healthy ecosystem. However, the Bay system remains degraded and some areas and indicators show continuing degradation. Progress in reducing nutrient inputs has made demonstrable improvements and we expect that continued progress toward nutrient reduction goals, along with appropriate fisheries management and chemical contaminant controls, will result in additional improvements to the Bay. An overall summary of findings for the major VA Bay tributaries (i.e. James, York, and Rappahannock Rivers) is bulleted below while the remainder of this …

Internal Phosphorus Loading In Spring Lake: Year 1, Dr. Alan Steinman, Dr. Rick Rediske

Scientific Technical Reports

The rate of phosphorus release from sediments, and the degree to which alum reduces phosphorus release from sediments, was investigated in Spring Lake during the summer of 2003. Triplicate cores were sampled from 4 sites in the lake, and exposed to one of four treatments in the laboratory: 1) oxygen/alum; 2) oxygen/ no alum; 3) nitrogen/alum; or 4) nitrogen/no alum. Both soluble reactive phosphorus (SRP) and total phosphorus (TP) release rates were virtually undetectable in the alum treatments (both with and without oxygen). Low, but detectable, release rates were measured in the oxygen/no alum treatment. The highest release rates were …

Bomb-Pulse Chlorine-36 At The Proposed Yucca Mountain Repository Horizon: An Investigation Of Previous Conflicting Results And Collection Of New Data, Klaus J. Stetzenbach, Fred Phillips, Drew Coleman, Don Baepler, Amy J. Smiecinski

Publications (YM)

Previous studies by scientists at Los Alamos National Laboratory (LANL) and the United States Geological Survey (USGS) quantified ³⁶Cl/Cl to test for the presence of fast pathways at the proposed Yucca Mountain high-level nuclear waste repository. The goal of these studies was to determine whether or not fluids containing bomb-pulse ³⁶Cl/Cl traveled along fast travel pathways and reached the repository horizon, however, the two groups followed somewhat different procedures and produced conflicting results. The objective of this study is to attempt to determine the cause of the conflicting results and to obtain additional data to determine whether or …

Decision Process For Identification Of Estuarine Benthic Impairments, Roberto J. Llansó, Jon H. Volstad, Daniel M. Dauer

Benthic Applications

To meet the requirements of the Clean Water Act, the States of Maryland and Virginia are in the process of developing biological criteria for evaluating estuarine waters. The Chesapeake Bay Benthic Index of Biotic Integrity (B-IBI) is the basis for these biological criteria. As an initial step, a Workgroup developed an interim framework for the application of the B-IBI to the States’ water quality inventory report (305b report) and list of impaired waters (303d list). The Workgroup included representatives of the Maryland Department of the Environment (MDE), Maryland Department of Natural Resources (MDNR), Virginia Department of Environmental Quality (DEQ), USEPA …

A Re-Evaluation Of The Us Epa Radon Risk Categorization For Unicoi County, Tennessee., William Grant Parsons

Electronic Theses and Dissertations

Effective risk communication is based on appropriate risk characterization. A reevaluation of the 1987 US EPA radon risk categorization of Unicoi County Tennessee was conducted using in-home radon concentrations, determined in a long-term monitoring study. Radon concentrations were measured in 69 homes using Electret Passive Environmental Radon Monitors (E-PERM’s), following standard methods. Radon concentrations determined in this study (avg. 4.03 ± 3.04) were significantly higher than those measured in the USEPA study (avg. 1.96 ± 1.08). Using this study’s data, the risk categorization was recalculated with the US EPA Radon Index Matrix Model. The model re-categorized Unicoi County from a …

The Distribution Of Phoshorus In The Nature Preserve At Clark County Wetlands Park In Las Vegas, Rosangela Gomez Brazao

UNLV Theses, Dissertations, Professional Papers, and Capstones

The main objective of this thesis was to investigate the distribution of phosphorus among three different compartments of the Upper Pond at the Nature Preserve at the Clark County Wetlands Park in Las Vegas, NV: influent and effluent water, sediments, and plants. Samples were collected from September 2002 to January of 2003 and analyzed for phosphorus content. Results showed that the Upper Pond removed 55% of the ortho phosphate (OP) and 39% of the total phosphorus (TP) loadings during the study period. Sediment results showed that the East Outflow concentrated the most P (644.85 ± 120.26 mg P Kg'1), followed …

Fisheries Research Contract Report No. 2 - Towards An Assessment Of Natural And Human Use Impacts On The Marine Environment Of The Abrolhos Islands (Phase 1 : Data Consolidation And Scoping - Final Report For Frdc Project 2000/1 66), C. F. Chubb, K. Nardi

Fisheries Research Contract Reports

This project has drawn together existing research data relating to natural and human impacts on the Abrolhos Islands marine habitats. It has surveyed current uses of these habitats and placed anthropogenic impacts within the context of natural perturbations. Through public forum presentation and debate, this work has allowed real issues, not perceptions, to surface and be addressed properly. This was achieved by defining a strategic programme of research through a scientific workshop process involving all community stakeholders. A two volume Fisheries Research Report (WA) summarizes current knowledge and details the workshop proceedings and strategic research plan.
