Reproductive strategies conferring species dominance in marine mysid (Peracarida, Mysida) species in coastal waters off Vancouver Island, BC
Bibliographic record
Abstract
Cold-water mysid species are key components of north Pacific coastal ecosystems and yet much of their life history remains unknown. In Clayoquot Sound, on the west coast of Vancouver Island, a dozen or so species have been identified, with four occurring consistently in samples: Holmesimysis sculpta (W. Tattersall, 1933), Neomysis rayii (Murdoch, 1885), Telacanthomysis columbiae (W. Tattersall, 1933) (Fukuoka & Murano, 2001) and Columbiaemysis ignota Holmquist 1982. In this article growth and reproduction of these species over a 24-month period (May 2010-April 2012) is described, showing recovery from annual removal by the eastern Pacific grey whale (Eschrichtius robustus (Lilljeborg, 1861)) over winter, when pressure from this main predator has been relieved. Holmesimysis sculpta dominates the species flock by employing different life history strategies. It is less seasonal than sister species, overcoming a presumed resource limitation scenario and exhibits year-round reproduction, thereby demonstrating more rapid population rebound following predation and, therefore, retain dominance.

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.
