ECO-001Retrieval lead
Sparrow abundance and measured base station fields
The reported finding
Discovery dossier reports negative association between house-sparrow abundance and measured GSM fields.
Reading it carefully
A retrieval entry, not a verified ecological causal conclusion.
Inside the study
Exposure conditions
See original source for calibrated field and modulation conditions.
Design & controls
Observational or experimental ecology; original methods pending.
The protection question raised
Does the sparrow-abundance association persist after accounting for habitat and other local conditions? Until original methods and analyses are checked, this is a field-observation lead rather than an ecological causal finding.
