The distribution of the invasive shrimp Neocaridina davidi in relation to environmental parameters in a stream at Kunitachi, Tokyo, Japan

What was studied

Study shape: Section-level shrimp counts were related to measured plants, water depth, current velocity, temperature and sediment using spatially adjusted generalized linear mixed models.

Experimental unit: Two or four square metre stream section, depending on sampling month

Endpoints: adult density, juvenile density, body size, environmental associations.

Claim boundary

What it can support: Adult density was positively associated with emergent plants, while juvenile density was negatively associated with measured current velocity in this stream.

What it cannot support: This observational field association does not assign aquarium flow, compare filter types, identify a turnover rate or make the observed density a home-aquarium capacity.

Correction impact

If this source boundary changes, these are the known downstream consumers. The list distinguishes scientific re-review from generated parity and historical follow-up.

Editorial review required (8)

This curated wording or synthesis must be reconsidered when the source boundary changes. A passing generator test cannot decide the new scientific meaning.

• filtration decision card Tank-side decision card
  The card translates this guide into an observation, first action, next record and stopping boundary, so all four require editorial review when the source changes.
• filtration practical guide Practical guide
  The guide uses this evidence record and its practical wording must remain inside the revised source boundary.
• carrying-capacity knowledge gap Canonical knowledge gap
  The current knowledge-gap boundary depends on a dated search that used this exact source and must be reconsidered if the source meaning changes.
• filter-turnover knowledge gap Canonical knowledge gap
  The current knowledge-gap boundary depends on a dated search that used this exact source and must be reconsidered if the source meaning changes.

Historical record needs follow-up decision (2)

Do not silently rewrite history. Decide whether the prior change record remains accurate and publish a new correction or scope note when needed.

• Do multigeneration complete-system experiments establish stable home-aquarium carrying capacity? Dated literature search
  The dated search used this exact source as a candidate (included: The distribution of the invasive shrimp Neocaridina davidi in relation to environmental parameters in a stream at Kunitachi, Tokyo, Japan). Preserve the search history and decide whether a revised or additional search is required.
• Does an assigned aquarium comparison establish a Neocaridina filter type, flow rate or turnover rule? Dated literature search
  The dated search used this exact source as a candidate (included: The distribution of the invasive shrimp Neocaridina davidi in relation to environmental parameters in a stream at Kunitachi, Tokyo, Japan). Preserve the search history and decide whether a revised or additional search is required.
