An environmental system which is a portion of the air, water, or land surface or subsurface of an astronomical body sampled in place, and which is neither bounded by a host organism nor constituted by a constructed or operated artefact. — HabitatMech

Curation

What a curator decided about this record, and why. A record built from several source concepts can carry one decision per concept.

CONFIRM_UNGROUNDED 2026-08-22 · codex-gpt-5
Confirmed UNGROUNDED: no ontology term fits this concept. ENVO:01000951 'natural environment' kept as an xref. Environmental is BacDive's level-1 counterpart of Host and Engineered. ENVO:01000951 'natural environment' is not its identity or parent: that term requires minimal to no anthropisation, while this provenance bin includes Indoor Air and other settings that do not make that claim. Earlier notes incorrectly cited Paddy, Grove, and herbaceous crop categories as children of BacDive Environmental; the committed MISO research shows they are under Engineered or Host. The near-miss remains an xref so it is not re-derived. (source concept habitatmech:BACDIVE.0f1e92a02c)
SAME_AS 2026-08-22 · codex-gpt-5
Merged into habitatmech:BACDIVE.0f1e92a02c 'Environmental': the same concept under another source's name. Novel-concept merge (#179): GOLD and BacDive use Environmental as the same level-1 provenance bin opposite host-associated and engineered sources. Keeping both published two terms for one concept and split 19,739 assertions. The BacDive identifier survives because it carries the larger attestation and characteristic taxa; the choice is otherwise arbitrary between minted source identifiers. Both source attestations remain distinct, and the survivor retains ENVO:01000951 as a near-miss xref. (source concept habitatmech:GOLD.c3fa7fc4c2)
DEFINED 2026-08-22 · codex-gpt-5
Defined as 'free-living environment' under ENVO:01000254 'environmental system'. Definition curated from both committed deep-research reports after merging the BacDive and GOLD level-1 provenance bins in #179. Free-living is the positive-polarity name used by EMPO. Anthropisation is deliberately not excluded because GOLD includes managed and contaminated settings; ENVO:01000951 natural environment remains only a near-miss xref.
