Fur Trade (FUR) — Biological Oscillator Analysis (1841-2013)

This dataset is part of the Bicameral Solar Engine project, a multi-scalar deterministic framework that maps the relationship between solar harmonic cycles and terrestrial systems including climate, economics, and biological populations. All datasets share a common methodology: raw signals are detrended using an 11-year centered moving average, normalized into Z-scores. Applies the BSE solar harmonic framework to Hudson's Bay Company lynx harvest records (1841–2013), treating the lynx population as a biological oscillator resonating near the 10.75-year solar fundamental rather than a passive receptor. Achieves 93.8% T(t) phase alignment and 93.8% transition alignment. Floor modulation confirmed: Growth phase population troughs systematically elevated above Decline troughs across 172 years. Documents 42.3% amplitude compression after 1928 at the Middle Gear Winter transition — coinciding with industrial-scale fur trade disruption. Extends Charles Elton's 1924 solar hypothesis with the formal gear structure his account required. This dataset and associated work are licensed under CC BY-NC-ND 4.0.
