Where the article explains it
Physically linked loci must be excluded or flagged , because the method’s entire logic depends on treating background disequilibrium as drift-generated between unlinked loci; loci close together on the same chromosome carry disequilibrium from physical linkage that has nothing to do with and will bias the estimate upward in apparent LD, downward in inferred .
The passage around this formula
What this means for study design , working backward from the estimator: . The genetic estimate and the demographic estimate from workflow one are not redundant. A mark-recapture study can show a stable or growing census count while an LD-based estimate reveals a much smaller effective size — a mismatch that is itself diagnostic, typically pointing to high variance in reproductive success (a few individuals contributing disproportionately to the next generation) or a historical bottleneck whose genetic signature outlasts the demographic recovery.
