Assessment

Why?

Strongest counted support: The primary study reports a sharp conflict increase below a mast threshold and additional amplification when an alternative food source also fails. weight 1.800000 evidence

Suppressed as dependent: The excerpt directly states that bear conflict is further amplified when the alternative food source, indexed by primary productivity, fails alongside mast production.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Leans supported to Leans contradicted.

Evidence for

• The primary study reports a sharp conflict increase below a mast threshold and additional amplification when an alternative food source also fails.

  The abstract directly reports amplification during concurrent food-source failure.

• The excerpt directly states that bear conflict is further amplified when the alternative food source, indexed by primary productivity, fails alongside mast production.

  The passage exactly supports the compound-failure relationship.

Evidence against

None.

Qualifications

• The amplification finding uses an 18-year five-prefecture dataset and indexes alternative food availability by primary productivity.

  The study-specific geography, time window, and primary-productivity proxy limit the claim’s scope.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
