Secondary and tertiary stress responses to BKME exposure in the St. Maurice River fish populations
Bibliographic record
Abstract
sucker In the St-Maurice River, Canada, white suckers (Catostomus commersoni) collected at two stations located down-stream of a bleached kraft mill effluent (BKME) outfall exhibited increased muscle lipid concentrations relative to upstream reference fish. White suckers collected in a physicochemically comparable but uncontaminated river, also demonstrated an increasing trend of lipid accumulation with distance downstream. The similar general trends in both rivers may result from a river continuum in which increasing loads of nutrients with distance downstream increase the energy available to fish. However, the general trends differed in two respects. The gradient of lipid accumulation in the St. Maurice R. was irregular, suggesting a sharply increased nutrient input by BKME. Secondly, in the reference Gatineau river, increased lipid reserves were accompanied by increased growth and reproductive effort relative to body size. In contrast, increased growth rates in the contaminated St. Maurice River were accompanied by a reduced reproductive effort relative to body size. The failure to translate increased energy intake, as indicated by increased muscle lipids, into increased reproductive effort suggests one or more components of BKME have a toxic effect. Accelerated river enrichment contributed by the discharge of the bleached kraft effluent combined with the natural river continuum made it difficult to isolate the reproductive effects related to effluent exposure. 1.

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.
