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.

Schindler 1974 backs nutrient (P and N) loading driving eutrophication and rapid recovery once phosphate is withheld; its abstract says nothing of bottom-water oxygen, dead zones, or sediment phosphorus release.
“Phosphate and nitrate caused rapid eutrophication. A similar result was obtained with phosphate, ammonia, and sucrose, but recovery was almost immediate when phosphate additions only were discontinued.”

- 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.

Schindler's whole-lake fertilization experiments show sustained phosphorus/nitrogen loading drives freshwater lakes to rapid eutrophication; the abstract says nothing about coastal systems, denitrification capacity, or flushing time.
“Combinations of phosphorus, nitrogen, and carbon were added to several small lakes in northwestern Ontario, Canada, at rates similar to those in many culturally eutrophied lakes. Phosphate and nitrate caused rapid eutrophication.”

- 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.

This abstract shows phosphate and nitrate additions caused rapid eutrophication in whole-lake experiments, but says nothing about low-level nutrient loading being beneficial or supporting a healthy food web.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 3 of 3 citations: 3 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
