Primes¶
- Eutrophication
- Marine and freshwater ecology (the canonical instance): nitrogen and phosphorus loading drives algal blooms; the bloom dies and sinks; decomposers consume bottom-water oxygen faster than mixing replenishes it; hypoxic dead zones form, with strong hysteresis on recovery as sediment chemistry releases stored phosphorus to fuel the next bloom.
This sourceWhole-lake experiments establishing phosphorus as the limiting nutrient whose loading drives algal blooms — the canonical eutrophication evidence.

- Input Pressure
- In eutrophication, a sustained nutrient input rate (agricultural runoff, sewage, atmospheric deposition) drives lakes and coastal systems toward algal-bloom regime shifts, with denitrification capacity and flushing time as response variables.
This sourceWhole-lake experiments establishing that the sustained nutrient (phosphorus) loading rate drives lakes into an algal-bloom regime.

- Overshoot and Collapse
- The enabling input is nutrient loading (phosphorus and nitrogen from agricultural runoff and wastewater), which is genuinely beneficial to the lake at low levels: it supports primary production and a healthy food web, so an oligotrophic lake can be made more productive by modest enrichment.
