Theory 70/Ecosystem/Biodiversity
Hotspots Balance Productivity and Season
The claim
Biodiversity hotspots occur where the ratio of productivity to seasonality is high, so the most productive stable regions hold the most species.
01Mechanism
Species require energy to persist and stability to specialise; the ratio captures both.
02Prediction
Richness should track the ratio.
03Refutation
Richness tracking productivity alone would remove seasonality.
