An Epigravettian Hypogeal Site In The Grotta Del Fiume Cave At Frasassi (Northeastern Apennines, Italy): Environmental And Geochronologic Assessments, Alessandro Montanari, Artur Adamek, Angelo Curatolo, Marco P. Ferretti, Maurizio Mainiero, Sandro Mariani, David Mcgee, Gaia Pignocchi, Stefano Recanatini

International Journal of Speleology

In the late fall of 1986, a team of cavers from the Gruppo Speleologico Marchigiano of Ancona reported to the regional Archeological Superintendence their discovery in a room of the Grotta del Fiume Cave (Marche region of central Italy) of archeological finds such as the charcoal remains of a bonfire, a number of ibex bones, and four chert artifacts. However, since the discovery and archival of all this material, no further research or focused studies were carried out about this important archeological site. Therefore, we engaged in a thorough re-examination of this site by mapping this part of the Grotta …

Assessing Drought Vegetation Dynamics At The Landscape Scale In Semiarid Grass- And Shrubland Using Mesma, Rowan Converse

Geography ETDs

New Mexico experienced substantial impacts of regional-scale drought from 2011-2014. Global climate change may make such events a new normal for the southwest: drought events are expected to increase in both frequency and severity over the coming century. While semiarid grasslands recover quickly from short-term drought, the cumulative impacts of climate change may reduce the resiliency of these systems over time. Remote sensing methods can allow efficient and cost-effective comparison of ecosystem recovery from drought events over time using long-running imaging systems like Landsat. We investigate the efficacy of using multi-endmember spectral mixture analysis (MESMA) to quantify the impacts of …

Phenotypic Analysis Of S. Aureus Strains From University Student Health Centers And Environmental Controls, Antonio Teixeira

Honors Theses

Methicillin-resistant Staphylococcus aureus (MRSA) is a group of pathogenic bacterial strains resistant to a class of antibiotics that is a major cause for concern in health care systems. There is a lack of study in whether health care centers are reservoirs for these bacteria, especially within developed countries. Five environmental swab samples were collected from five different university health care centers across the region, and 16 swab samples from a general university environment. Any isolated bacterial strains collected underwent five biochemical tests (mannitol fermentation, DNase activity, oxidase activity, catalase activity, and coagulase activity) to preliminarily identify S. aureus bacteria. 24% …

Spatial Distribution, Sources, And Associated Risks Of Toxic Metals In Red Sea Sediments Near Jeddah, Saudi Arabia, Riyadh Halawani

Civil and Environmental Engineering Theses and Dissertations

Coastal areas are known to be sequestration points for various pollutants generated from industrial and urban activities. Diverse anthropogenic pollutants are typically delivered to coastal sediments via atmospheric or fluvial processes. Heavy metals, such as chromium, copper, manganese, zinc, and lead, are some of the toxic contaminants of greatest concernbecause of their well-established detrimental effects on the marine environment. In recent years, Saudi Arabia has encouraged activities to bring about economic development, particularly along the Red Sea. Jeddah is located on the Red Sea and is the second largest city in Saudi Arabia, famous for its beautiful coral reef.

Space And Depth-Resolved Naturally Occurring Toxic Groundwater Species In Bangladesh And Rwanda: Origination And Risk Analysis, Kenneth Hamilton

Civil and Environmental Engineering Theses and Dissertations

Access to safe potable water is a necessity for all. Groundwater is a commonly relied upon drinking water source for many areas around the world. This is especially true for communities in high density, rural settings. Such is the case for populations near Cox’s Bazaar, Bangladesh, and in the Bugesera region of Rwanda. Sediment and groundwater contamination, through toxic dissolved species, represents a significant public health risk to exposed populations. Tropical soils, such as the soil profiles in Bangladesh and Rwanda, often contain higher concentrations of heavy metals (Rieuwerts, 2007). Additionally, nitrate from fertilizers, are widely used on the soils …

The Slow Creep Of Settler Colonialism: Exploring Water Control In Palestine, Lina Abu Akleh

Master's Theses

This thesis analyzes the Israeli-Palestinian water issue using a settler colonial framework. It highlights the contributions made to this field under the often used framework of hydro-hegemony to understand water issues in Israel-Palestine. Using a settler colonial framework helps to better describe the issue and highlight the slow creep of settler colonialism over the years. It also helps to see beyond the power dynamics and its relationship to domination and consent to understand the realities that Palestinians face on the ground. In addition, this thesis will help build towards exploring resistance to water control under settler colonialism. Therefore, this thesis …

The Socio-Environmental Politics Surrounding The Commodification Of Guayusa In The Ecuadorian Amazon, Molly Silk

Master's Theses

Guayusa, a tree used for its leaves, that when dried, boiled, and consumed in tea form, acts as a natural stimulant due to its high levels of caffeine. Initially used among Kichwa people, the plant is thought to be a panacea with abilities to heal health complications such as infertility, headaches, and nausea. In addition, the Kichwa community holds an incredibly strong ritualistic and cultural connection to the tea. Guayusa is said to connect the person and community to the dream world through the process of gathering in the early hours of the morning to drink the tea, and decipher …

Estimation Of Evapotranspiration And Energy Fluxes Using A Deep-Learning-Based High-Resolution Emissivity Model And The Two-Source Energy Balance Model With Suas Information, Alfonso F. Torres-Rua, Andres Ticlavilca, Mahyar Aboutalebi, Héctor Nieto, Maria Mar Alsina, Alex White, John H. Prueger, Joseph Alfieri, Lawrence Hipps, Lynn Mckee, William Kustas, Calvin Coopmans, Nick Dokoozlian

Civil and Environmental Engineering Faculty Publications

Surface temperature is necessary for the estimation of energy fluxes and evapotranspiration from satellites and airborne data sources. For example, the Two-Source Energy Balance (TSEB) model uses thermal information to quantify canopy and soil temperatures as well as their respective energy balance components. While surface (also called kinematic) temperature is desirable for energy balance analysis, obtaining this temperature is not straightforward due to a lack of spatially estimated narrowband (sensor-specific) and broadband emissivities of vegetation and soil, further complicated by spectral characteristics of the UAV thermal camera. This study presents an effort to spatially model narrowband and broadband emissivities for …

A Colonial Climate: Climate Change Governance In Puerto Rico, Usa, Justin Grant Pearson

Master's Projects and Capstones

This capstone project examines the relationship between the colonial structures of governance that persist in Puerto Rico and how they affect the island’s resilience to the onslaught of climate change. Within the frameworks of climate change, governance and colonialism, I set out to analyze the means by which Puerto Rico’s status as a colony of the United States has led to its history and present circumstances that have left a gap in terms of effective governance at the federal and other upper levels of government. The conclusion made is that there needs to be a greater level of focus placed …

What Does A "Just" Local Food System Look Like? Views From Worcester In A Changing Climate, Marguerite Cawley

Capstone Collection

Food and climate are closely intertwined, with the high-emissions U.S. industrial food system contributing to climate change, while a changing climate produces new food system vulnerabilities, which will particularly impact those of the least means. This research is premised on the need to transform our food system, and to define what this vision looks like at the local level, while centering questions of power, justice and rights. It explores how groups, organizations and individuals engaged in local food system change envision transformation and understand corresponding social justice concerns, in a changing climate. It looks at opportunities for food and climate …

Communal Reciprocity In The Andes: An Ethnohistorical Approach To The Relationship Between Ayni And Food Production, Catherine Curran

Spanish Honors Papers

Ayni, or reciprocity, historically characterizes Quechua culture as a fundamental aspect of ancient Andean societies. Furthermore, ayni represents a cosmovision that may come from pre-Hispanic times (as a political practice and ideology of the Inca Empire), that can be found in the texts of historians of the colonial period and endure to the present day. In this way, ayni is an ancient principle that has influenced Andean communities and continues to maintain today as a way to re-energize and maintain livelihood of the community through environmental conservation and complex household economies of sharing land, labor, and food. Due to …

Coronavirus Closures Could Lead To A Radical Revolution In Conservation, James Stinson, Elizabeth (Libby) Lunstrum

University Author Recognition Bibliography: 2020

In the early days of the COVID-19 lockdowns, social media was flooded with reports of animals reclaiming abandoned environments. According to one widely shared post, dolphins had returned to the canals of Venice.

While many of those stories have since been debunked, conservationists are providing legitimate reports of cleaner air and water, and wildlife reclaiming contested habitats.

With widespread closures of parks and conservation areas around the world, could this be an opportunity to transform the way we manage and use these protected environments?

Evaluating The Hydrologic And Thermal Performance Of A Green Roof In Syracuse: Measurements And Modeling Of A Full-Scale System, Yige Yang

Dissertations - ALL

Climate change and urbanization have increased the risk of flooding and combined sewer overflows as well as other stormwater related problems. Given the high costs of traditional infrastructure rehabilitation, green infrastructure, which mimics natural systems, has become a popular solution. Green roofs are one prominent example of green infrastructure. These are engineered vegetative systems positioned on the top of roof structures have been widely adopted around the world, owing to an abundance of roof area in urban neighborhoods. However, their hydrologic performance and thermal properties are unclear, due to a lack of qualitative and quantitative analyses on monitored full-scale green …

The organization of ecological assemblages has important implications for ecosystem functioning, but little is known about how scavenger communities organize at the global scale. Here, we test four hypotheses on the factors affecting the network structure of terrestrial vertebrate scavenger assemblages and its implications on ecosystem functioning. We expect scavenger assemblages to be more nested (i.e. structured): 1) in species‐rich and productive regions, as nestedness has been linked to high competition for carrion resources, and 2) regions with low human impact, because the most efficient carrion consumers that promote nestedness are large vertebrate scavengers, which are especially sensitive to human …
