Claim
In the study's analysis, bear conflict is further amplified when an alternative food source fails in the same period as mast production.
Topics
Assessment
Leans supported
Main unresolved issue: 3 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:9fad0958-b016-8d07-a75a-7a488643b961
Not yet independently audited.This assessment depends heavily on modeling choices.
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.

Summary
Leans supported. The main support is: The primary study reports a sharp conflict increase below a mast threshold and additional amplification when an alternative food source also fails. 14a1654b
1 further item repeats the same origin and is not independent evidence. fdfab947
Qualifier: The amplification finding uses an 18-year five-prefecture dataset and indexes alternative food availability by primary productivity. d546d1c4
A search for evidence in the opposing direction found none. b64f1808
