Relative importance of parental diet versus larval nutrition on development and phenotypic plasticity of <i>Pseudechinus huttoni</i> larvae (Echinodermata: Echinoidea)
Bibliographic record
Abstract
Abstract The relative importance of parental and larval diets on development of larvae of the sea urchin Pseudechinus huttoni was examined. Laval parameters measured included the size of body components, development rate, morphological phenotypic plasticity, mortality rate, protein, lipid, carbohydrate and energy contents. We also investigated the influence of parental nutrition on fecundity, egg diameter and the eggs' protein, lipid and carbohydrate content. For a period of one year, adult P. huttoni were fed kelp (Macrocystis pyrifera) ad libitum every second day as a low-quality diet, or kelp ad libitum every day plus cockle (Austrovenus stutchburyi) flesh once a week as a high-quality diet. Adults fed the high-quality diet produced larger eggs and larvae with a slower development rate, longer arms relative to the midline length, and lower protein, lipid and carbohydrate contents. In larvae, higher concentrations of planktonic diet led to larger body components, a faster development rate and shorter arms relative to midline length. This study showed that parental nutrition has an important effect on development rate and morphological phenotypic plasticity in larvae of P. huttoni.

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.
