Macroplastic Characteristics And Assessment Of The Plastic Abundance Index (Pai) Of Beach Sediments In Prigi Bay, East Java, Indonesia, Adinda P.A. Nevandhra, Seftiawan S. Rijal, Syarifah H.J. Sari, Defri Yona

Applied Environmental Research

Macroplastics, defined as plastic debris ranging from 2.5 to 100 cm, pose significant threats to aquatic ecosystems, as they can breakdown into smaller particles. These materials are widely dispersed across marine environments, including coastal areas. This study aimed to compare and assess the abundance of macroplastics in the foreshore and backshore zones of four beaches around Prigi Bay, East Java, Indonesia, via the plastic abundance index (PAI). Macro-plastics were collected via a 5×5 m quadrat transect method. The results revealed that single-use plastics, particularly packaging and sachets, dominated both zones, accounting for 86% and 91% of the total number of …

Applying Radom Forest And Support Vector Machine For Land-Use Classification In Phu Giao District Vietnam, Trong Dieu Hien Le, Linh Truong Vinh

Applied Environmental Research

Machine learning algorithms are currently widely used to classify satellite images to create surface maps of the earth. Support vector machines (SVMs) and random forests (RFs) are more effective ML algorithms and more accurate classifications than other methods. The aim of this study is to analyze the performance of these two algorithms in land-use and land cover classification. For this purpose, the Landsat 8 OLI satellite image freely provided by the United States Geological Survey (USGS) was used to classify land use in the Phu Giao District, Binh Duong Province, Vietnam, where forestland is being strongly converted into rubber plantations …

Mycorrhizal Type Mediates Plant-Soil Feedback And Density Dependence In A Sri Lankan Rainforest, Akshay Surendra

Yale Graduate School of Arts and Sciences Dissertations

How do so many species of trees coexist in a forest? A century of research has discovered multiple mechanisms that could maintain local-scale diversity. Chief among them, at least at early life stages, is a pattern of stronger neighborhood competition from conspecifics than heterospecifics. This pattern is driven, at least in part, by specialized natural enemies such as insects and pathogens that damage host trees more than others. Unsurprisingly, the strength of neighborhood effects varies widely among species and a current avenue of research involves understanding what explains this variation. A major axis of variation that has emerged among trees …

Critical Environmental Communication Framework, Shumaila J. Bhatti, Srivi Ramasubramanian, Andrea Feldpausch-Parker, Bruno Takahashi, Silje Kristiansen

Media Studies - All Scholarship

This study develops a Critical Environmental Communication (CEC) framework to assess the landscape of Environmental Communication research and to what extent and in which ways critical and justice-oriented perspectives are included. The CEC framework consists of four interconnected themes: (a) Marginalized Ecocultural Identities, (b) Context and Scale, (c) Power and Agency, and (d) Justice, Equity, Diversity, Access, and Inclusion (JEDAI). Using this framework in a bibliometric analysis examining 1,297 Environmental Communication publications, we assess the occurrence of these themes in the scholarship. Our analysis found that Marginalized Ecocultural Identities, and Context and Scale were most frequently occurring, while Power and …

Factors Affecting Freshwater Fish Communities In Two North Alabama Counties, Joshua Fitts

Theses

This study examined how physical habitat characteristics influence freshwater fish diversity in streams of Madison and Limestone Counties, Alabama. Ten 150-meter stream reaches were sampled using backpack electrofishing and seining, with habitat variables measured at fixed transects. Principal component analysis identified four main habitat gradients representing flow and substrate, channel size, gravel dominance, and canopy–bedrock conditions. Although overall species richness and Shannon diversity were not significantly related to these gradients, species-specific correlations revealed clear ecological preferences. Regression models showed that root wads, herbaceous vegetation, and riprap modestly increased richness, emphasizing the role of structural diversity. These findings highlight the importance …

Renewable Energy Federalism 2.0, Danielle Stokes

Law Faculty Publications

Much like climate change, the clean energy transition presents a “super wicked” problem that is further complicated by prioritizing justice. History has taught us that government regulation, industry innovation, and community engagement are the catalysts of effective transitions. Similarly, the just energy transition requires the support of these interconnected networks. This Essay offers sustainable collaborative governance as a theoretical framework through which decision-makers may filter their assessments, industry can model its metrics, and community can develop language to articulate its needs. Sustainable collaborative governance is also a means of navigating the complexities of renewable energy siting and regulation while fostering …

Distributional Considerations In Climate Economics, Simon Fridtjof Lang

Yale Graduate School of Arts and Sciences Dissertations

Climate change and climate policies have distributional consequences on a global scale. Climate impacts are unevenly distributed, responsibilities for emissions vary across countries, and capabilities to mitigate and adapt differ. These distributional aspects are at the heart of international climate policy discussions. In response, international climate finance—financial transfers from developed to developing countries for climate mitigation, adaptation, and damage compensation—has become a central topic in international climate negotiations. The three chapters of this dissertation explore distributional considerations in climate economics from different perspectives and assess how optimal climate policy may depend on these considerations.

The first paper examines how the …

Identifying The Spread Of Invasive Jumping Worms Across Maine’S Forests Using Soil Edna, Rebecca Wanger

Honors Theses

Jumping worms of the Megascolecidae family are invasive earthworms from East Asia that have been spreading across the United States since the late 1800s (Chang et al., 2021). Recently, the earthworms have gained more attention for their expansion into northeastern states, as they are believed to have negative impacts on the soil biogeochemistry, flora, and fauna of these forest ecosystems that have had no native earthworms given the recent nature of the Last Glacial Maximum (~11,000 yrs ago; Bohlen et al. 2004; McCay et al. 2020). The earthworms are distinguished by their thrashing behaviors, milky-white smooth clitellum, and evenly spaced …

An Apple A Day: Have The Growing Conditions Of Apples In Maine Changed Over The Past 20 Years, Anooshka Sethi

Honors Theses

Climate change is increasingly affecting the growing conditions that farmers face. This study focused on if and how the growing conditions of apples have changed over the past two decades. Apples are an economically, socially, and culturally important crop to Maine's agriculture landscape. By production acreage, Maine is the second largest state in New England, with 2700 acres of land used to grow apples (USDA NASS CoA, 2022). A unique characteristic of agricultural production in Maine is that most farms are small-scale, run by families or small groups, making adverse changes to the growing conditions of a major crop in …

In Harmony: The Environmental Lives Of Marianne North, Beatrix Farrand, And Mary Hunter Austin, Willa Frank

Pomona Senior Theses

This thesis explores the lives and careers of botanical painter Marianne North, landscape architect Beatrix Farrand, and literary nature writer Mary Hunter Austin to examine the interplay of femininity and the representation of nature in the late nineteenth and early twentieth centuries. All three figures had an approach to environmental representation which was based in field work, knowing a place truly, and a sense of harmony between subject and context of the produced work. This method did not occur because they were women or because it was an inherent feature of their assigned sex. Rather, their socialization in the Anglo-American …

Adaptation For Whom? Understanding The Impacts Of Dyke Policies On Small-Scale Farmers In Ca Mau Province Of Vietnam, Nguyen Minh Quang, Nguyen Van Minh, Nguyen Vo Chau Ngan, Martha B. Lerski

Publications and Research

Low-lying deltas worldwide are extremely vulnerable to sea-level rise. As the risks of climate-induced flooding become increasingly clear, the thirst for infrastructure-driven adaptation increases. This highlights a patent need to understand the impacts of engineering adaptation solutions, especially those targeting built structures such as dykes and sluices, on farmers from a bottom-up, farmer-centred perspective. The study addresses this call by examining cases where dyke policies, while successful in some dimensions, have undermined small-scale farmer livelihoods in Ca Mau ― Vietnam’s southernmost rural province. It identifies areas in need of attention and adds empirical data related to this group of farmers. …

No Evidence For Sex-Specific Visual Acuity In Anolis Aquaticus, Samantha Garnsey, Janelle Talavera, Lindsey Swierk

Research Days Posters 2025

Sex differences in sensory perception are widespread among animals, driven by sex-specific reproductive challenges. Males and females often exhibit different sensory abilities, such as in visual acuity; for example, in Heliconius butterflies, males exhibit greater visual acuity due to their mate-seeking behaviors. This study examined this idea in Anolis aquaticus, a semi-aquatic lizard with sexual dimorphism. Males court females using a colorful throat fan (dewlap), which females use to select mates. It is predicted that females will have greater visual acuity than males, given their reliance on visual signals for mate choice. A custom-built apparatus was used to test 45 …

A Look Into How Green Binghamton Really Is, Eva Mandelbaum

Research Days Posters 2025

In 1987, the UN defined sustainability as “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” College campuses often appear filled with a desire for social change, including climate action and sustainability initiatives. But how much do students know—or care—about the initiatives on their own campus? If people view environmentalism and sustainability as imperative solutions to pressing issues that most people should care about, they are more likely to take action to encourage them. By surveying members of the Binghamton University community, this study gauges public perception of on-campus sustainability and …

The Arctic Ocean Region : Biodiversity, Governance And Protective Measures, Antonios Andreadakis, Graeme Chesters, Dimitrios Dalaklis, 90 North Foundation

Reports

EXECUTIVE SUMMARY

• The Arctic Ocean region stands at the forefront of global environmental transformation, serving as a harbinger of climate change and a frontier for emergent geopolitical and economic interests.

• The Arctic region's economic potential, particularly in shipping and resource extraction, appears to offer shorter trade routes, reduced fuel consumption, and increased access to high-value resources. However, this analysis largely ignores the complex geo-physical, environmental and geographical limitations of the region.

• The fragility of Arctic Ocean ecosystems – characterized by slow ecological recovery, specialised biodiversity, and extreme environmental conditions – renders them especially vulnerable to anthropogenic disturbances. …

Bridging The Green Divide: Sustainable Community Development And Climate Resilience In Altadena, Ca, Katie Brosnan

Pitzer Senior Theses

Sustainable Community Development (SCD) is widely debated as a climate mitigation strategy, with recognized benefits such as reducing carbon footprints, enhancing public health, and fostering economic resilience. However, a major critique is its limited accessibility to marginalized communities. In particular, the resilience embedded in rebuilding plans does not necessarily translate to real access for those whose insurance coverage may not be sufficient to afford conventional design services or reconstruction costs. This thesis argues that while SCD is an effective tool for climate mitigation, its success depends on equitable access—not just in principle, but in the material capacity to participate in …
