Population Size and Site Fidelity of North Atlantic Minke Whales (Balaenoptera acutorostrata acutorostrata) off the Atlantic Coast of Nova Scotia, Canada
Bibliographic record
Abstract
The site fidelity of North Atlantic minke whales (Balaenoptera acutorostrata acutorostrata) off the coast of Halifax, Nova Scotia, Canada (approximately 1,800 km^sup 2^) was examined and their population size estimated. During 258 d of boat-based surveys, 1,158 photographs (black and white film plus digital) of minke whales were collected during the summer months (primarily June through August) between 1997 and 2008. While 100 individuals were identified over the 10-y study, only 40 individuals possessed reliable marks (notches on the dorsal fin). Of the unique (i.e., reliably marked) individuals, 35% were observed on more than 1 d (14/40), and 12.5% were photographed in more than 1 y (5/40). The population size was estimated to be 43 unique individuals (28 SE) with an estimate loss rate (that includes mortality, permanent emigration, and mark change) of 35.2%/y (28.1 SE). As 51% of the population was estimated to possess reliable marks, the total population size for this area was estimated at 84 individuals.

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; a candidate call from one teacher head, not a consensus.
