A salmon ecosystem conceptual foundation for estuary restoration
Bibliographic record
Abstract
A cohesive recovery strategy for Pacific salmon populations requires a shared conceptual foundation to coordinate management actions across jurisdictions and interests. We examined an estuary restoration program as a case study of a life history ecosystem framework proposed for Columbia River salmon conservation in 1999. The estuary program lacks an explicit framework to account for cross-scale connections to other salmon life stages. We propose the following conceptual foundation, composed of three guiding principles: (1) the estuary is a subsystem of a complex natural-cultural system connected by salmon life cycles; (2) a dynamic mosaic of estuarine habitats supports growth, ontogenetic development, and life history variations of salmon throughout the basin; and (3) physical and biological processes beyond the estuary limit opportunities for salmon life history expression within it. These principles require additional estuary performance indicators to coordinate water and fishery management programs and to adapt estuary restoration actions to a changing climate.

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.
