Replacement Laying in Marbled Murrelets Brachyramphus Marmoratus
Bibliographic record
Abstract
Replacement laying gives seabirds an opportunity to increase reproductive success.For the Marbled Murrelet (Brachyramphus marmoratus), a threatened seabird, estimating productivity is of particular importance to conservation management plans.However, fecundity is not well known, and replacement laying has not been previously recorded.We report on the first confirmed case of replacement laying in the Marbled Murrelet.As well, we used a combination of radio telemetry, physiological analysis of vitellogenin, and brood patch examination, to estimate the frequency of renesting from 1999 to 2001 in Desolation Sound, British Columbia.Replacement laying was estimated to occur at a rate of between 13% to 63% annually.This work demonstrates that additional reproductive capability exists for Marbled Murrelets when first breeding attempts fail, and has implications for other studies of threatened species.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
