The ultrastructure of sea turtle eggshell does not contribute to interspecies variation in fungal invasion of the egg
Bibliographic record
Abstract
The eggshells of green ( Chelonia mydas (L., 1758)), loggerhead (Caretta caretta (L., 1758)), hawksbill ( Eretmochelys imbricata (L., 1766)), and flatback ( Natator depressus (Garman, 1880)) sea turtles nesting in eastern Australia were examined by scanning electron microscopy to determine if the ultrastructure was contributing to interspecific variation in fungal invasion of eggs. The eggshells of all species investigated were of similar structure (outer inorganic layer of aragonite crystals and an inner organic fibrillar layer) and of similar thickness. Well-defined pores that would allow direct entry of fungal hyphae or spores were not present in any species. It was concluded that the eggshell ultrastructure does not allow direct access by fungal hyphae or spores and does not contribute to interspecific variation in the vulnerability of loggerhead sea turtle eggs to fungal infection.

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.
