Patterns of predator-prey dynamics between gray whales (Eschrichtius robustus) and mysid species in Clayoquot Sound
Bibliographic record
Abstract
The patterns of foraging intensity of gray whales (Eschrichtius robustus) over a 17-year period (1997–2013) in Clayoquot Sound, Vancouver Islandare examined. In this area, epibenthic mysid species are gray whales’ primary prey. The analysis indicates a top-down modification on habitatquality by this apex predator. Intense foraging in one or two summer season contributes to reduced prey resources available in the following summer.Years of heavy predation pressure were followed by at least one year of reduced foraging, probably allowing a reprieve in which the mysids couldrepopulate. Over the time span several patterns were noted including: boom-bust cycles; extended periods of reduced foraging; an overall decliningtrend of foraging whales using Clayoquot Sound, followed by a significant prey recovery in 2010. Life history patterns of mysids are discussed inthe context of their ability to recover from predation, and how this recovery during a reprieve may buffer the intensity of foraging from the previousyear. The continuing ability of mysids to recover from repeated and persistent removal will determine the use of Clayoquot Sound as a gray whaleforaging area in the future.

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.
