Metal contamination co-selects AMR mechanisms
Metal-contaminated environments carry higher AMR burden or different AMR mechanism composition after controlling for taxonomy and site context.
Opportunity Hooks
Open Tensions
Metal contamination co-selects AMR mechanisms
Hypothesis
Metal-contaminated environments select for AMR mechanisms directly or indirectly through shared transport, stress response, mobile elements, or ecological filtering.
Testable With
AMR annotations, metal tolerance scores, metal type diversity, prophage/mobile-element burden, soil or site geochemistry, ENIGMA site context, and phylogenetic controls.
Failure Mode
Taxonomic composition, mobile-element burden, co-contaminating metals, spatial sampling, or project effects explain the signal. The test must include nulls, stratification, and sensitivity analyses.
