Unseen Connections: A Storymap Exploring Case Studies In Water-Energy Transitions And Environmental Justice, Alida Cantor, Elizabeth Bartholomew, Kate Berry, James Blair, Dustin Mulvaney, Nancee Hunter

Geography Faculty Publications and Presentations

Climate change is one of the most important challenges in the world today. Communities and decision makers at many levels, from local to international, are working to ensure that energy, water, and other societal infrastructures can transition and adapt to address climate change (IPCC, 2023). One major mitigation strategy involves the decarbonization of energy systems (Rockström et al. 2017). Despite wide recognition of the need to decarbonize globally, renewable energy infrastructures and technologies are often locally controversial, involving claims of environmental injustice and disputes over land and water (Cantor, Turley, and Maxfield 2023; Jerez, Garcés, and Torres 2021; Turley et …

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 …

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 …

Heat And Hardship: Energy Price Increases And Heatstroke Risks In Japan During The Global Energy Crisis, Kenshin Ueoka

CMC Senior Theses

Given the global rise in surface temperatures due to climate change, it is important to understand the interactions governing economic and behavioral responses to household heat adaptation. This study investigated the relationship between energy prices and heatstroke risks in Japan. The analysis revealed that the increase in energy prices during the 2021 global energy crisis was associated with an unexpected decrease in home heatstroke emergency room visits. This result is consistent with the Peltzman effect and moral hazard problem, as reduced economic access to air conditioning may have increased risk perception, heightening heatstroke prevention measures. The ambiguity of this result …

Substrate Preference And Foraging Behavior Of Two Declining Warblers In Appalachian Shrublands, Samantha Fishman

Theses and Dissertations

Abstract Shrubland and early successional habitats (ESH) support a diversity of wildlife, including many declining songbirds. However, nonnative shrubs increasingly dominate these habitats, potentially altering habitat quality by influencing prey availability. Habitat quality can be assessed by observing foraging behaviors of songbirds and identifying preferred and avoided substrates as well as testing the predictions of optimal foraging theory; specifically that birds will maximize their energy gain relative to the costs. We examined foraging behaviors of Golden-winged Warblers (Vermivora chrysoptera; GWWA) and Chestnut-sided Warblers (Setophaga pensylvanica; CSWA) in ESH on private lands in Virginia with varying amounts …

Stage-Specific Disruption Of Cancer Cell Metabolism By Pfas: Connecting “Forever Chemicals” To The Growing Public Health Challenge Of Colorectal Cancer, Hannah O'Halloran

Public Health Theses

Per and polyfluoroalkyl substances (PFAS), termed “forever chemicals” for their persistence in the environment, are under investigation for their carcinogenic effects, but their specific impacts on colorectal cancer (CRC) progression remain largely unexplored. This study uses untargeted metabolomics to examine the effects of PFAS exposure on cells of CRC stages 2, 3, and 4, and identify state-specific alterations in important metabolic pathways. Later stage cells exhibit a greater response than early stage cells, suggesting increased susceptibility to PFAS effects in cells of more advanced cancer. PFOS had a greater effect on the metabolism of the cell lines compared to PFOA, …
