Theory 60/Population/Population cycles
Cycles Need a Time Ratio
The claim
Population cycles occur when the ratio of generation time to resource renewal time falls within a range, so slow-renewing resources produce longer cycles.
01Mechanism
Delayed feedback between consumer and resource produces oscillation when the delay matches the renewal time.
02Prediction
Cycle period should track the ratio.
03Refutation
Cycles tracking reproduction rate alone would remove renewal.
