- Increasing application of road deicing agents (e.g., NaCl) has caused widespread salinization of freshwater environments. Chronic exposure to toxic NaCl levels can impact freshwater biota at genome to ecosystem scales, yet the degree of harm caused by road salt pollution is likely to vary among habitats and populations. The background ion chemistry of freshwater environments may strongly impact NaCl toxicity, with greater harm occurring in ion-poor, soft water conditions. In addition, populations exposed to salinization may evolve increased NaCl tolerance. Notably, if organisms are adapted to their natal lake water chemistry, toxicity responses may also vary among populations in a given test medium. We examined how this evolutionary and environmental context may interact in shaping NaCl toxicity with a pair of laboratory reciprocal transplant toxicity experiments, using natural populations of the water flea Daphnia ambigua from three lakes differing in ion availability. The lake water environment strongly influenced NaCl toxicity in both trials. NaCl greatly reduced reproduction and r in lake water from a low-ion/ calcium-poor environment compared with water from both a calcium-rich lake and an ion-rich coastal lake. Daphnia from this coastal lake were most robust to the effects of NaCl. A significant population x environment interaction shaped survival in both trials, suggesting that local adaptation to the test waters used contributed to toxicity responses. Our findings that the lake water environment, adaptation to that environment, and adaptation to a focal contaminant may shape toxicity demonstrate the importance of considering environmental and biological complexity in mitigating pollution impacts.

- In the 1950s and 1960s, Arab nationalism swept across the Arabian Peninsula from Egypt and the Levant, carried by migrants, refugees, and in magazines and newspapers that circulated across national borders. In the Gulf countries this wave of Arab nationalism collided with a flow more material in nature: the movement of enormous amounts of carbon energy in the form of oil. In Arab nationalism, oil workers at Aramco in Saudi Arabia and Bapco in Bahrain found not only a direction for political change but a means of overcoming religious and national divides with their fellow workers. Strikes and labor actions soon ensued at a scale that was unprecedented in these countries. This project explores how the confluence of oil flows and anticolonial nationalism both imbued this moment with the potential to effect egalitarian political change and, simultaneously, limited that potential.

- This paper examines three works of animal-based fiction published within the last decade that all center on hypothetical forms of animals with a focus on decentering anthropocentric narratives of how much agency an animal is allowed to have in a human-centric narrative without engaging in anthropmorphism. By comparing the books with theory from the academic field of animal studies, older works of animal-based fiction, and historical debates surrounding the depiction of real-world animals in writing, I aim to interrogate the methods these authors use to decouple their animals' agency from anthropomorphism, and the ways in which this shift allows anthropocentrism to take new forms rather than be eradicated.

- Suite for a Changing Climate is a set of compositions inspired by the changing rhythms of the New England seasons and the evolving ways in which we experience them in the shadow of climate change. Each piece captures a distinct facet of the seasonal year, whether rooted in sensory experience or in cultural memory, while reflecting on how these once-familiar patterns are being reshaped by environmental instability.
