Trichomycete prevalence in Thomas Brook, Nova Scotia, exposed to different levels of human activity
Bibliographic record
Abstract
The Thomas Brook in the Annapolis Valley, Nova Scotia, was the focus of an Agriculture and Agri-Food Canada wastershed evaluation of beneficial management practices (WEBs) project from 2004–2008. The stream is impacted by human activities along its course, with residential influences and farming operations. The water quality in Thomas Brook was assessed in 2006, and the current study done in 2011–2012 used the same standard invertebrate metrics to measure water quality. This project also examined the prevalence of gut endosymbionts (trichomycetes) in aquatic invertebrates to determine whether water quality affects this community of obligate microorganisms in their hosts. The water quality was improved in Thomas Brook in 2011/2012 compared with that measured in the earlier study. There were 34 taxa of trichomycetes recorded in benthic insects in the stream, including two new species. The trichomycete community was rich in dipteran hosts (midges and black fly larvae), but the prevalence of gut fungi in ephemeropteran (mayfly) nymphs in the system was low, perhaps due to the impact of human activities on water quality.
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.
