Population counts do not directly measure individual growth or fecundity
The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.
What changed
The chemical-safety guide now distinguishes aquarium counts by size class from tracked individual growth, gonad output, egg production and fecundity.
Why it changed
The five-month experiment followed changing colony abundance and life-stage classes. It did not follow individual growth trajectories or directly measure gonads and eggs, so slower reproduction and growth remain interpretations of population patterns.

Affected practical guides
A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
