Abstract
From a faunal list of 216 of the most common species of prosobranch gastropods at Beaufort, North Carolina, a group of 87 species was selected on the basis of known life cycles and geographic distributions. The larval types were categorized as teleplanic, actaeplanic, or nonplanktonic. The presence of these species in eight approximately equivalent latitudinal zones along the western shore of the Atlantic Ocean was then recorded (Scheltema, 1989). This list has been used, in the present paper, in three different ways: to identify homogeneity or heterogeneity of spatial distribution of the three biological groups; to record the presence of species in geographic sectors defined on the basis of average annual sea surface temperature; and to compare, at the two extremes of the region studied, the areas occupied by species having a particular type of development in common. It was found that: 1) the dominant type of development within a latitudinal zone depends on the geographic position of this zone; 2) the extent of the area of distribution of species with a given type of reproduction varies with latitude; 3) in terms of sea surface temperature limits, teleplanic and nonplanktonic species have similar patterns of distribution; 4) the distributions observed, whether along the coastline or transoceanic, are not fully accounted for by the inherent dispersal capacities related to larval type.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
