Using Bivalves As An Indicator For Fecal Bacteria, Kamala Chuss

Honors Scholar Theses

This project focuses on the integration of fecal bacteria from warm-blooded animals into bivalve tissue, and the utilization of bivalves as an indicator for fecal bacteria in waterways. Bivalves may give a more representative long-term average of fecal bacteria in water as compared to direct water testing. The primary objective is to create a standard operating procedure to use bacterial testing of bivalves as a proxy for bacteria concentration in the water. This method can be used in places where bivalves do not already exist by adding them to a body of water, or by collecting bivalves that already exist …

Invasion Stress Mitigates Climate Stress In A Brackish Marsh Amphipod, Lorna E. Haworth, Sarah Nancollas, Susie N. Landa, Anne E. Todgham, Richelle L. Tanner

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

1. Organisms in coastal brackish ecosystems face not only highly variable environmental conditions, but the intensity and stochasticity of these environmental conditions are anticipated to increase due to climate change. While environmental changes are often presented unilaterally as stressors, there are some anthropogenic environmental transformations, such as the introduction of habitat forming plant species, that may mitigate physiological stress imposed by warming. In Suisun Marsh in the California Delta, native plant canopies allow light and heat to penetrate to the understory yet the canopies of the introduced Phragmites australis reed block out sunlight and heat for organisms living below.

Phytoplankton As A Bioindicator For Evaluation Of The Irrigation Water Quality Near A Metal-Coating Factory, Mimatun Nasihah, Ardyati Ardyati, Dian Siswanto, Catur Retnaningdyah

Makara Journal of Science

The irrigation water quality in Plosowahyu village, Lamongan District, Indonesia, has declined because of industrial waste disposal in irrigation canals. Specifically, waste from a metal-coating factory considerably threatens the aquatic ecosystem. To assess the impact, we evaluated water quality on the basis of phytoplankton diversity and various phys-icochemical parameters. We collected water and phytoplankton samples from four locations in Plosowahyu village: before the wastewater treatment plant (WWTP) outlet of the metal-coating factory, at this outlet, and from two sites in Wahyu River, with three repetitions at each site. The study measured several physicochemical parameters, including total dissolved solids (TDS), total …

Security At Too High An Environmental Cost?: The European Union's Energy Independence Strategy And Its Environmental Implications For Air Quality In Poland And Hungary, Stephanie P. Peterson

The Journal of Purdue Undergraduate Research

After Russia’s invasion of Ukraine in 2022, the European Union worked to secure liquified natural gas (LNG) deals with third countries to abolish its dependence on Russian gas. In this article, I sought to determine the environmental implications of the European Union’s new LNG deals on the air quality in Hungary and Poland, two former communist states. Despite LNG being a cleaner fossil fuel, I hypothesized that it posed a threat to Hungary’s and Poland’s air quality as both countries endured rapid industrialization under Soviet control that forwent environmental protections. To prove this, I used qualitative data from before the …

Embodied Cognition And Teaching Stem: Tenets To Explain And Enhance A Middle School Science Project, Jonathan E. Roberts, Joshua L. Williams, Robert A. Hodgdon, Caroline Payne, Gabriela Ruiz Emmanuelli

Current Issues in Middle Level Education

STEM pedagogy is a popular area for research and discussion. The empirical literature on this topic supports a variety of approaches (e.g., inquiry-based) to help instructors spark student interest create an effective learning environment, and foster long-term retention and transfer of information related to STEM topics. One potential approach is to use tenets of embodied cognition, in which behavior and cognition emerge out of real-time sensorimotor behavior of the individual situated within a particular context, to implement strategies to enhance STEM pedagogy. We applied the six lessons of embodied cognition to understand the beneficial aspects of a middle-school project on …

Geomorphic Evolution Of St. Augustine Inlet, St. Johns County, Florida, Kristen Becker

Theses and Dissertations

Tidal inlets interrupt longshore sediment transport, influencing adjacent beach morphology and allowing the exchange of water and sediment between the open oceans and protected back barrier bay. Inlets evolve through a combination of natural processes and are highly dynamic zones where sediment exchanges cause shifting shoreline positions nearby and create new morphological features. Barrier islands/beaches that are close in proximity to inlets evolve and are an important natural feature that dissipates wave energy and protects inland areas. Both natural and anthropogenic processes that affect barrier islands will be investigated during this study, including storm activity, waves, wind, water level, and …

¿Qué Futuro Les Espera A Los Trabajadores Latinos? El Calor Extremo, Las Promesas Vacías Y La Incertidumbre Política, Yunior Rivas Garcia

Capstones

Este artículo explora las condiciones mortales que enfrentan los trabajadores latinos en Estados Unidos debido al estrés por calor, un riesgo creciente en sectores esenciales como la construcción, la agricultura y el almacenamiento. A pesar de representar una proporción significativa de las muertes laborales, las protecciones contra el calor son insuficientes, y la falta de regulación federal agrava la vulnerabilidad de estos trabajadores, muchos de los cuales son indocumentados. A través de casos específicos, como la muerte de Esvin Cruz Mateo, y un análisis de las políticas laborales actuales, el texto examina las fallas estructurales que perpetúan la inseguridad laboral …

Identifying Opportunities For Nature-Based Solutions With Geospatialized Life Cycle Assessments And Fine-Scale Socioecological Data, Gabriela Shirkey, Annick Anctil, Ranjeet John, Venkatesh Kolluru, Leah Mungai, Herve Kashongwe, Lauren T. Cooper, Ilke Celik, Joshua B. Fisher, Jiquan Chen

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

As we increasingly understand the impact that land management intensification has on local and global climate, the call for nature-based solutions (NbS) in agroecosystems has expanded. Moreover, the pressing need to determine when and where NbS should be used raises challenges to socioecological data integration as we overcome spatiotemporal resolutions. Natural and working lands is an effort promoting NbS, particularly emissions reduction and carbon stock maintenance in forests. To overcome the spatiotemporal limitation, we integrated life cycle assessments (LCA), an ecological carbon stock model, and a land cover land use change model to synthesize rates of global warming potential (GWP) …

Are There Neurological Impacts Of Exposure To A Burned Wildfire Site As It Recovers?, Rubye Strickland

Undergraduate Honors Theses

Wildfires are increasing with climate change, making the human health implications of exposure to burned soils an essential area of research. Metals associated with fire-impacted soils can be inhaled or accidentally ingested by surrounding communities, causing health risks. Several studies have evaluated the health impact of wildfires, but few have done so from a neurological perspective. This study explores metal changes in burned soils over time as a site naturally recovers from wildfire and how these changes may impact human neurological health. Soil samples were collected from the burned area 0, 3, 6, 9, and 12 months after the fire. …

Climate- And Land-Use Change Impacts On Ecosystem Services Provided By Prairie Pothole Wetlands, Alina Mullins

Master's Projects and Capstones

Prairie pothole wetlands are a type of depressional, isolated wetland that can be found in the glaciated landscape of the mid-central United States and portions of southern Canada, also referred to as the Prairie Pothole Region (PPR). The region is consistently recognized for its historic production and support of migratory waterfowl populations among other types of mammals and invertebrates largely due to the variability in pothole wetlands water levels and vegetative structure. Isolated from other waterbodies and lacking surface water connections, the hydrology of prairie pothole wetlands is influenced by the region’s continental climate. Historically, the region receives much of …

Identifying Fecal Contamination Sources In The Grand Bay National Estuarine Research Reserve, Amanda M. Free

Theses and Dissertations

The Grand Bay National Estuarine Research Reserve (GNDNERR) has a history of elevated fecal coliform counts. However, the source of the contamination is not well understood. According to past sanitary surveys, there has been a history of malfunctioning residential septic systems and inadequate wastewater treatment in the upper watershed. Feral hogs (Sus scrofa) and birds are also abundant in the estuary and could be potential contributors to elevated fecal coliform levels. To better understand the temporal and spatial variation of fecal coliforms in the GNDNERR and inform oyster reef management, eight sites within the GNDNERR watershed were sampled monthly for …

Investigations Of Guayule Resin As A Wood Protectant, Queen Aguma

Theses and Dissertations

Wood products are subject to deterioration by numerous processes, as a biological material. Today, a significant area of preservative development is the utilization of existing plant residues that have water-repelling, antibacterial, antifungal, and insecticidal properties as components of wood protectants. Parthenium argentatum, known as guayule (wy-oo-lee), is a promising wood protectant due to its resin. However, the resin's complicated chemical, physical, and solvent-resistant properties make it difficult to use. The primary goal of this study was to eliminate the use of any solvent and rely on thermal modification only to fractionate usable compounds from guayule resin. Utilizing heated dialysis and …

Recovery Of Black Carbon Concentrations In Burned Forests In Wyoming, Usa, Monica Vanesa Zapata Villegas

Dissertations and Theses

Burned forests that remain standing following fire release light-absorbing particles (LAPs), including black carbon (BC), into winter snowpacks, reducing snow surface albedo and accelerating snowmelt timing for decades postfire. Although the role of LAPs in seasonal snow has been extensively studied, the spatiotemporal variability of LAPs' contributions to snowmelt relative to time-since-fire and burn severity remains unknown. This study aimed to quantify the spatiotemporal variability of forest fire effects on LAPs in snow and associated snow albedo in the Triple Divide region of western Wyoming, headwaters of the Colorado, Columbia, and Missouri rivers. Using geochemical analysis and radiative transfer modeling, …
