Worlding the end: A story of colonial and scientific anxieties over beavers' vitalities in the Castorcene
Bibliographic record
Abstract
This article examines a technoscientific project for eradicating the North American beaver in Tierra del Fuego (TDF), an austral region known as “The End of the World.” Introduced from Canada into TDF in 1946 to promote a fur industry, beavers are today classified as an alien and invasive species that severely threatens the pristine native ecosystems of TDF. We analyze the environmental history of beavers in TDF to explore the many partial losses that have shaped beaver-human relations across hemispheres. We argue that various ends of the world have mediated different technoscientific responses to beavers’ vitalities, reflecting multiple forms of human anxiety over loss and extinction. Thinking with the beavers and their environmental history in TDF, we explore the “Castorcene” as the human anxiety that emerges from beavers' vitalities. As an analytical concept, the Castorcene de-universalizes the Anthropocene, decolonizes extinction horizons, displaces human exceptionalism, and situates and singularizes imaginaries of the end of the world.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
