Preliminary assessment of the ectomycorrhizal fungi of <i>Quercus garryana</i> on Vancouver Island, British Columbia, Canada
Bibliographic record
Abstract
Garry oak ( Quercus garryana Douglas ex Hook.) is the only oak native to British Columbia (BC), where it occupies the northernmost extent of its range. The ecosystem it occupies in BC has been greatly reduced in size and fragmented by European settlement. Garry oak forms ectomycorrhizas that are essential to its existence and will likely play an important role in the response of this tree to climate change. Yet, relatively little is known about the ectomycorrhizal fungi associated with Garry oak in BC. In this study, we have documented the occurrence of fungi forming ectomycorrhizas with Garry oak at six locations on Vancouver Island by sequencing the internal transcribed spacer region of ectomycorrhizal root tips collected from Garry oak stands. Of the 47 species we detected, only about 20% can be confidently assigned to known species because not all species have been sequenced and many sequences in public databases are incorrectly or incompletely identified, but the majority of them belong to a community of fungi associated primarily with oaks or other members of Fagaceae. The uniqueness of this community of ectomycorrhizal fungi indicates that the possible expansion of the range of Garry oak in BC in response to climate change may be limited by the co-migration of its ectomycorrhizal fungi.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
