Abstract

fetched live from OpenAlex

Abstract Oxygen uptake rates were measured in fasted and fed Platorchestia platensis (Krøyer, 1845) to estimate the energy required for ingestion, digestion, absorption, assimilation and growth. A modified population specific dynamic action model (SDA pop ) was compared between two populations fed either wrack or driftwood. Results reject the null hypothesis: that both populations have equal energy requirements during digestion, as might be the case if native enzymes alone were involved. The alternate hypothesis that driftwood-fed P. platensis have a significantly lower SDA than wrack-fed ones was supported. Our oxygen uptake measurement experiments could not distinguish between two possible causes of the lower energetic costs associated with driftwood-fed P. platensis : driftwood as a poor-quality food and/or a microbial subsidy effect. Preliminary microbiological studies of P. platensis do support the subsidy effect, because cellulose-degrading bacteria and filamentous fungi were present in whole body tissues from the animal. Wrack and driftwood culture treatments of P. platensis supported a different cellulose-degrading microbiome between the two treatments.

Full frame distilled prediction

Teacher imitation

Not 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.
