Leaf preference and leaf breakdown are not complete-diet results

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 research map now separates leaf choice, litter decomposition, water chemistry and long-term shrimp outcomes, and adds a direct cattail-decomposition study to the full-text screening queue.

Why it changed

The indexed record exposes a useful contact-versus-feces microcosm design, but complete methods remain unavailable and the study measured one river shrimp population with one cattail litter rather than catappa, alder, dietary adequacy, disease, survival, growth or reproduction.

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.
