Distribution of arbuscular mycorrhizae in relation to microsites on primary successional substrates on Mount St. Helens
Bibliographic record
Abstract
Arbuscular mycorrhizae fungi (AMF) occur in most terrestrial ecosystems and are crucial to plant community structure and function. This study examined the distribution of AMF propagules, spores, and colonized plants across the Pumice Plain of Mount St. Helens 23 years after its eruption, documenting the changes since 1993. Propagules of AMF were detected by using the mycorrhizal inoculum potential assay in six microsite types across the Pumice Plain. Fifteen species of AMF were isolated from spore trap cultures, and spores were found in all of the microsites, although the distribution was aggregated. The vegetation of the Pumice Plain is currently composed primarily of facultatively mycotrophic species, which are predominantly associated with arbuscular mycorrhizae. Mycorrhizal colonization and propagule levels continue to increase as primary succession proceeds.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
