Abstract

fetched live from OpenAlex

Human beings' domination of the planet has not been kind to many species worldwide.This is to be expected.Humans have radically altered natural landscapes, harvested heavily from the ocean, and altered the climate in an unprecedented way.Recent concerns over the extent and rate of biodiversity loss have led to renewed interest in extinction outcomes and speculation concerning humans' potential role in any future mass extinction.In this paper, we discuss the economic causes of extinction in two high-profile cases -Sharks and the North American Buffalo -and then extend our framework to allow for multiple species and the possibility of mass extinction.Throughout, we present evidence drawn from authoritative data sources with a focus on shark populations to ground our analysis.Despite large gaps in our data, the available evidence suggests extinction risks are rising for many species and policy is slow to react.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
