Escape and survival of<i>Corophium volutator</i>and<i>Ilyanassa obsoleta</i>exposed to freshwater and chlorothalonil
Bibliographic record
Abstract
The behavioural response and survival of marine mud snails and mud shrimp exposed to freshwater and the fungicide chlorothalonil (tetrachloroisophthalonitrile) was investigated. Amphipods were less tolerant of lower salinity than snails, with 50 and 76% survival associated with 5 and 0% seawater in freshwater, respectively. However, 50% of snails displayed a defence mechanism by retracting within their shell when exposed to 70% freshwater. Both species displayed an avoidance to chlorothalonil spiked at >100 ng/g and/or >100 ng/mL in sediments and seawater, respectively. The avoidance response of amphipods was observed along with a reduced swimming ability and increased lipid content. Snails displayed a higher susceptibility to physical stress, with an increased number unable to twist from being on their shell to their foot, and with longer righting time. Behaviour was affected at chlorothalonil concentrations of 0.001-0.01 ng/g and/or ng/mL, with a variability that could be due to degradation by the microbial community. Ascertaining the latter observations requires state-of-the-art chemical analyses.

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.
