Effects of Temperature and Salinity on Emergence of<i>Gynaecotyla adunca</i>Cercariae from the Intertidal Gastropod<i>Ilyanassa obsoleta</i>
Bibliographic record
Abstract
Fluctuating abiotic conditions within intertidal zones have been shown to affect the emergence of free-swimming trematode infectious stages (cercariae) from their gastropod first intermediate hosts, likely reflecting adaptations to maximize transmission in this marine environment. We investigated the influences of temperature (17 and 22 C) and salinity (25, 30, and 35 ppt) on the emergence of marine cercariae (Gynaecotyla adunca) from their mud snail first intermediate host ( Ilyanassa obsoleta ). Cercariae emerged in greater numbers at 22 C and the 2 lowest salinities, with a sharp decrease at the 35 ppt level, but there was no interactive effect. We discuss these patterns of G. adunca emergence as possible adaptations to facilitate transmission to its amphipod second intermediate host ( Corophium volutator ) in conditions common to the Upper Bay of Fundy.

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.
