Constructed Wetland Treatment System: An Approach For Mitigating Risks Of Flue Gas Desulfurization Waters, Derek Eggert

All Dissertations

Federal laws regarding ambient air quality are currently requiring industries to reduce emissions of sulfur dioxides (SO2). Coal-fired power plants have therefore begun implementing flue gas desulfurization (FGD) scrubbers that utilize a highly oxygenated water stream (calcium carbonate saturated water) to transform sulfur gases into soluble anion species (e.g. sulfite and sulfate). This FGD process also transfers potentially toxic constituents including arsenic, cadmium, chemical oxygen demand, copper, mercury, selenium, chloride, sulfates, and zinc into the scrubbing water. These scrubber waters, referred to as FGD waters, present an industrial problem due to the large volumes produced (378,000 to 1,900,000 L/day) and …

How Healthy Is The Magoon Pond Watershed

Watershed Access Lab Projects

Located down the street from my house is the Magoon Pond. I conducted an independent Study to determine the relative health of the Magoon Pond. This pond is a tributary of the North River in Marshfield, Massachusetts. To access the health will we be using a macro-invertebrate biological index as our primary tool. We will also be taking depth and flow measurements to conduct a stream profile and discharge value. To start with we scouted the watershed and choose three different test sites to use, an Inlet site, a Pond site and an Outlet site.

The pond was within a …

An Analysis Of The Environmental And Hormonal Effects On The Growth And Development Of The Moss Ceratodon Purpureus, Megan Knight

Undergraduate Honors Thesis Collection

Ceratodon has not been documented in scientific literature as thoroughly as other species of moss such as Funaria or Tortula. Commonly known as fire moss or purple horned moss, Ceratodon is often reddish or yellow-brown and the spore capsules are usually purple (Crum, 1983). A picture of the species growing in its natural habitat is shown in Figure 4. Ceratodon often grows in tufts and is considered a weed, often thriving in polluted or disturbed areas and frequently invading after a fire (Crum 1983). Ceratodon belongs to the class Bryopsida, which also contains the previously mentioned Funaria and Tortula species. …

Hyperspectral Reflectance For Rapid Viability Assessment Of Bacillus Endospores, Jarrod Edwards

Theses and Dissertations

A study was conducted to optically determine the viability of the Gram +, endospore-forming bacterial genera Bacillus using a hyperspectral reflectance spectrometer. Endospores are a dormant, differentiated cellular capsule form taken by select bacteria to ensure survival when environmental conditions become unfavorable. Two species of Bacillus were used for this study, Bacillus megaterium and Bacillus subtilis. These endospores were killed using a chemical treatment of sodium hypochlorite or a physical treatment of heat and pressure in an autoclave. The treated samples along with viable samples were lyophilized to form a powder. A reflectance spectrometer measuring 350 nm to 2500 nm …

Constraints On The Utility Of Mno2 Cartridge Method For The Extraction Of Radionuclides: A Case Study Using 234Th, M. Baskaran, P. W. Swarzenski, B. A. Biddanda

Environmental Science and Geology Faculty Research Publications

Large volume (10²–10³ L) seawater samples are routinely processed to investigate the partitioning of particle reactive radionuclides and Ra between solution and size-fractionated suspended particulate matter. One of the most frequently used methods to preconcentrate these nuclides from such large volumes involves extraction onto three filter cartridges (a prefilter for particulate species and two MnO₂-coated filters for dissolved species) connected in series. This method assumes that the extraction efficiency is uniform for both MnO₂-coated cartridges, that no dissolved species are removed by the prefilter, and that any adsorbed radionuclides are not desorbed from …

Elemental Composition And Nutrient Effect On The Uptake And Metabolism Of Dissolved Organic Carbon By Bacteria From A Temperate Region River, Anne Stuart

Theses and Dissertations

Rivers are arteries that connect land and sea, and provide a conduit and reactor for allochthonous and autochthonous organic carbon sources (OC) delivered to the coastal ocean. In comparison to marine waters, inland waters quantitatively represent only a fraction of the marine system; however, their importance to global C cycling maybe disproportional to its actual size. Inland systems are subject to multiple sources of OC (autochthonous and allochthonous) that vary individually in space and time with respect to their concentration and potential bacterial bioavailability. This study investigates the impact of high and ambient inorganic nutrient concentrations on the bacterial bioavailability …

The Responses Of Blue Crabs (Callinectes Sapidus) To Hypoxia/Hypercapnia In Freshwater, James Martin

Theses and Dissertations

The present research examined respiratory responses of blue crabs to long term (4, 13, and 21 days) hypercapnic hypoxia in freshwater at 23 C. Hypoxic conditions (50-60 & 75-85 mmHg O2) were induced by allowing the crabs to consume their oxygen supply, resulting in a hypercapnic induced decrease in pH that remained through the exposure. Postbranchial hemolymph responses to hypoxia/hypercapnia in freshwater demonstrate decreases in PO2, increases in PCO2, and decreases in pH. Lactate levels decreased over time, but hemocyanin concentration was highly variable with no trends. PH, lactate, and hemocyanin observations also demonstrated high variability and a variety of …

Role Of Bcl-2 Family Members To Promote Glucocorticoid –Induced Apoptosis By Mek Inhibitors In Leukemic Cells, Anila Rambal

Theses and Dissertations

Glucocorticoids (GC) are common components of many chemotherapeutic regimens for lymphoid malignancies. GC-induced apoptosis involves an intrinsic BCL-2 family-regulated pathway. It has been shown that BIM (BCL-2 interacting mediator of cell death), a BH3-only pro-apoptotic protein, is up-regulated by dexamethasone (Dex) treatment in acute lymphoblastic leukemia (ALL) cells. Furthermore, BIM is inactivated by extracellular signal-regulated kinase (ERK)-mediated phosphorylation. We therefore hypothesized co-treatment with Dex and MEK/ERK inhibitors would promote apoptosis in ALL cells through BIM up-regulation and activation. We show here that a MEK inhibitor, PD184352 synergistically enhances Dex lethality in CCRF-CEM (T-ALL) cells. Co-treatment with Dex and PD184352 results …

Phylogeography Of The Rufous-Naped Wren (Campylorhynchus Rufinucha): Speciation And Hybridization In Mesoamerica, Hernan Vazquez-Miranda, Adolfo G. Navarro-Siguenza, Kevin E. Omland

School of Natural Resources: Faculty Publications

The Rufous-naped Wren (Campylorhynchus rufinucha) is a sedentary, morphologically variable species distributed in the dry forests of Mesoamerica. It ranges from Colima, Mexico, south to Costa Rica along the Pacific slope, with a disjunct population in central Veracruz. Populations of two forms on the Pacific slope intergrade in Chiapas, Mexico, apparently as a result of secondary contact. We sequenced a mitochondrial DNA (mtDNA) gene to explore phylogeographic patterns and hybridization. We found three divergent lineages, two geographically spanning the Isthmus of Tehuantepec and a disjunct Veracruz population. Analyses of molecular variation and statistics are consistent with genetically distinct …

Patterns Of Abundance Across An Urban-Rural Gradient For Commonly Found Indigenous Arthropods, David Jones

Theses and Dissertations

Abstract Proof of concept for a continuous environmental sampling methodology that employs common terrestrial arthropods as environmental samplers was tested by analyzing pitfall, malaise and black light captures over a six month period over a replicated urban-suburban-rural gradient in Central Virginia. All arthropods captured at the nine sites were identified and assigned to aquatic, vegetation, or soil groups based on their association with these microhabitats. To offset variability in arthropod life history patterns and species abundance within habitat types, arthropod categories based on presence/absence data over the six month period were constructed to provide for sampling reliability within each microhabitat …

Estimating The Effects Of Detection Heterogeneity And Overdispersion On Trends Estimated From Avian Point Counts, Matthew A. Etterson, Gerald J. Niemi, Nicholas P. Danz

United States Environmental Protection Agency: Publications

Point counts are a common method for sampling avian distribution and abundance. Although methods for estimating detection probabilities are available, many analyses use raw counts and do not correct for detectability. We use a removal model of detection within an N-mixture approach to estimate abundance trends corrected for imperfect detection. We compare the corrected trend estimates to those estimated from raw counts for 16 species using 15 years of monitoring data on three national forests in the western Great Lakes, USA. We also tested the effects of overdispersion by modeling both counts and removal mixtures under three statistical distributions: …

A Comparison Between Above-Water Surface And Subsurface Spectral Reflectances Collected Over Inland Waters, Asif M. Bhatti, Donald Rundquist, John Schalles, Luis Ramirez, Seigo Nasu

School of Natural Resources: Faculty Publications

The objective of the research was to undertake a quantitative comparison of spectral-reflectance measurements made slightly above the surface of water bodies with the measurements made slightly below the surface. The study is focused on three rivers; two in Georgia, USA and one in Japan. As expected, the differences in reflectance are not constant and vary with the wavelength. The contribution of surface-reflection effects to the surface reflectance measured slightly above the water is both pronounced and highly variable, but although they do alter the magnitude of the upwelling signal, they do not change the general shape of the spectral …

Natal And Breeding Dispersal Of Bobolinks (Dolichonyx Oryzivorus) And Savannah Sparrows (Passerculus Sandwichensis) In An Agricultural Landscape, Natalia Fajardo, Allan M. Strong, Noah G. Perlut, Neil J. Buckley

Environmental Studies Faculty Publications

Dispersal is a key process in the metapopulation dynamics and genetic structure of spatially segregated populations. However, our knowledge of avian dispersal, particularly in migratory passerines, remains limited. We studied dispersal of Bobolinks (Dolichonyx oryzivorus) and Savannah Sparrows (Passerculus sandwichensis) to determine whether agricultural management practices affected dispersal patterns and habitat selection. From 2002 to 2006, we banded adults and nestlings on six focal hay fields and two pastures in the Champlain Valley of Vermont and New York and searched for banded birds within 1.5 km of Vermont field sites during two years. Natal dispersal distances were …

Fisheries Research Report No. 189 - Results Of A 2007 Survey Of The Swan River Region For Four Introduced Marine Species, Justin I. Mcdonald, Fred E. Wells

Fisheries Research Reports

A survey of the Swan River region for four non-indigenous marine species was conducted in 2007: the European shore crab Carcinus maenas, the Asian bag mussel Musculista senhousia, the European fan worm Sabella spallanzanii, and the scallop Scaeochlamys livida. The first three of these species are global in their distribution and on the ‘top-ten world’s worst invaders listing; the last species is introduced from the eastern states of Australia.

In this survey divers on SCUBA examined 43 sites for each of the listed species. Despite previous records of Carcinus maenas and Musculista senhousia in this region …

The Realities And Effectiveness Of Ecotourism Operations On Moreton Island, Yoshihiko Kubota

Independent Study Project (ISP) Collection

Ecotourism is the fastest growing sector of the tourism industry, but there has been a lack of studies assessing the tour operators’ views on the environment of the area of their operation, and of the effectiveness of their interpretation methods. This study focuses on Moreton Island for its relatively undisturbed environment and restricted accessibility.. Interviews with a former Environmental Protection Agency (EPA) employee, representative of a local conservation group, and multiple tour operators were conducted to assess the knowledge of tour operators on the environmental issues of Moreton Island, while pre-visit and post-visit surveys were conducted with Moreton Island visitors …

National Parks In China: A New Model For Nature Conservation, Katherine Fritz

Independent Study Project (ISP) Collection

When the author of “China has First National Park” published in The Science News-Letter in 1948, he could not foresee the next 60 years of China’s struggle to develop an effective nature conservation system. If he had, he would have known that simply recognizing the value of precious land, as China did in 1948, does not automatically lead to a sophisticated, nation-wide national park system.

National parks are the hallmark of advanced civil society and complex government conservation schemes. Since the State Forestry Department declared China’s first officially protected space at Dinghu Shan Nature Reserve in Guangdong province in 1956 …
