On Spanish farms, wildlife cameras detected more taxa than water eDNA
WHAT THE EVIDENCE SAYS
Researchers compared camera traps and environmental DNA water sampling across 13 farms in Spain. Under their sampling design, camera traps detected higher taxonomic richness; eDNA detectability varied with animal ecology and group behavior. Molecular water signals also varied with some livestock-density measures.
WHY IT MATTERS / OUR READ
An assay can be technically sensitive yet miss animals that rarely contact the sampling medium. Wildlife disease-interface monitoring is strongest when detections are designed around the species and behavior being measured, rather than declaring one tool universally superior.
CAVEATS / UNCERTAINTY
One waterbody was sampled per farm and trap placement and effort differed by method. No pathogen transmission or disease reduction was demonstrated.
