Abstract

fetched live from OpenAlex

AbstractNear-bed gradients in suspended particle quality and material ingested by Spio setosa were studied using an intertidal beach population in Nova Scotia. Spio builds a sand tube that allows it to feed several centimeters above the bed, where hydrodynamic sorting of horizontal transport provides low-density, high-quality organic seston. Characterization and enumeration of particles from both worm guts and ambient sediment in the field demonstrated that guts were enriched in organic mineral aggregates relative to the bed. In a laboratory flume, worms with tubes shortened to bed level received and ingested seston of significantly lower organic quality than worms feeding in intact tubes 4–6 cm above the bed. Because tube building requires ∼2.5 days, winter beach scour which removes tubes may force Spio to feed frequently at suboptimal heights above the sediment surface. The dependence of suspension feeders on organic-mineral aggregates and the tendency for these particles to incorporate estuarine pollut...

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.
