Abstract
The factors influencing the habitat requirements and dispersal of juvenile Unionidae (unionids) between post-larval detachment from a fish host and burrowing into the substratum are largely unknown, although bed shear stress (τw) has been proposed as a critical factor. We used a laboratory wall jet apparatus to manipulate τw experimentally to examine the suspension and burrowing of juvenile Epioblasma triquetra, Villosa iris, Lampsilis fasciola, and Ligumia nasuta. τw and unionid suspension were significantly related when τw > 0.26 Pa, but this relationship also was influenced by mussel behavior. Greater τw was required for suspension when a mussel’s foot adhered to a surface. Laboratory experiments confirmed predictions that juvenile unionids cannot become established when τw exceeds a critical value. Hydrodynamics and behavior strongly affect dispersal by juvenile mussels and may influence juvenile mussel habitat requirements, and thereby have implications for conservation efforts.

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 it
