Abstract
Changes to the Speed River fish assemblage were investigated 27 years after the creation of the Guelph Lake reservoir. Electro-fishing and seine haul data collected during 2003 were compared to pre- (1975) and post-impoundment (1976 and 1978) surveys. Since its creation, the Guelph Lake fish assemblage has predictably shifted from one dominated by fluvial specialists (fantail darter and creek chub) to one dominated by habitat generalists common to lakes and reservoirs (bluntnose minnow, pumpkinseed sunfish and black crappie). Since 1975, species richness and diversity have increased at un-impounded sites along the Speed River. The occurrence of new species in Guelph Lake and upstream along the Speed River is attributed to the stocking of non-native species. Reductions in the distribution and abundance of certain fluvial specialists (fantail darter and northern hogsucker) are attributed to the flooding of riverine habitat and changes to downstream habitat conditions. Observed long-term changes to fish assemblage were not evident from earlier post-impoundment surveys.

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.
