Environmental perturbations associated with the late-Permian mass extinction and Early Triassic recovery are widely studied, and our understanding of global events during this biotic crisis continues to improve. Marine carbonates preserve geochemical proxy records of global chan…

The cause for large mammal extinctions in the Late Pleistocene has been debated for decades, with two main factors constantly discussed--human hunting and climatic change. The Cypriot pygmy hippopotamus represents a case study of one such extinction event. The last appearance of…
The purpose of this investigation is to determine the preferred habitats of Sivapithecus and whether changes in habitat or climate may have led to its extinction. This research incorporates both dental microwear and carbon and oxygen stable isotopic analyses from a wide range of…
Estimates of insectivorous bat diversity in the Palaeotropics have been hampered by the lack of long-term studies employing appropriate capture techniques. Using a variety of trapping methods, with the emphasis on an intensive harp-trapping protocol, I captured 42 species in 2 k…
The capercaillie is the largest member of the grouse family extant in Scotland. This species is reported to have become extinct during the 1700s. It is also reported to have been reintroduced to Scotland from Sweden during the 1800s. There have been many assertions made about th…
Behavioral momentum theory research has demonstrated that differential reinforcement of alternative behavior (DRA) based interventions, while decreasing the rate of a target response (i.e., problem behavior), may in fact increase the persistence of the target response when there…
We present the Coma Cluster Core Project (C3PO), a deep, high resolution and contiguous mosaic survey of the inner ⇡ 150 squarearc minutes of the core of the Coma Cluster. The region was tiledby 21 HST/WFC3 pointing and was observed in F336W from the UVIS channel, and F160W from…
Extinction rates exceed any in recent history. Simultaneously, invasive species are invading new areas and increasing in abundance. The leading proposed drivers of biodiversity loss include habitat destruction, urban and agricultural development, climate change, and biological i…
The Specter of Extinction: Environmental Nihilism in British Science Fiction (1800–1945) argues that the history of British science fiction is inextricable from the career of human extinction as a concept. Charting literary depictions of human extinction through the end of the S…
A central goal of conservation biology is to identify and understand the factors that lead to extinction. The Earth is currently undergoing a 6th mass extinction event, in large part because of human activity. In the last century, rates of extinction have increased anywhere from…
Geochemical data and outcrop observations are used to reconstruct palaeoceanographic conditions in western Panthalassa across the transition from the Permian to the Early Triassic. Major, minor and trace element data were measured from the Lower and Middle Permian Johnson Canyon…
Interstellar dust is a ubiquitous component of galaxies, but some of its most fundamental properties are still poorly understood. This work analyzes the average extinction properties of dust in the Small Magellanic Cloud (SMC) through color-magnitude diagrams (CMDs) of resolved …
This thesis considers the potential of grief and mourning to foster meaningful engagement with global ecological crises. I explore this potential through my own studio practice, positioning artworks and creative processes as vehicles for articulating collective experiences of lo…
In the Productivore’s Dilemma three overarching claims are explored in a manuscript of chapters split into two parts: First, that human and more-than-human life is not only threatened by extinction but is more importantly threatened by systemic extermination. Second, utilizing t…
Bees have played an important role throughout human history; from cultural traditions to medicine, bees have been interwoven into our society. They have also been scientifically studied for thousands of years as they play integral roles in both our agricultural systems and natur…
The random dynamics of a population evolving in time is a phenomenon worthy of mathematical study. From examining genetic drift and tracing genetic diseases to the recent increased interest in genetic ancestry reports, it is clear that there is a strong need for deepening and ex…
