The Distribution and Conservation Status of the White Colour Morph of Faxonius propinquus (Northern Clearwater Crayfish) in Lake Simcoe, Ontario, Canada
Bibliographic record
Abstract
Abstract The white morph of Faxonius propinquus was first identified and described by Dunham and Jordan. They subsequently documented the presence and geographic distribution of other species in Lake Simcoe, including two additional colour morphs of F. propinquus (Dunham et al. 1979). Since then, no further research has been conducted on these populations, even though the lake has now been invaded by the introduced rusty crayfish (Faxonius rusticus). The present study documents the decline and most recent distribution of the F. propinquus colour morphs and the other native species, Faxonius virilis, which also appears to display several unusual colour morphs in Lake Simcoe. The decline of the various colour morphs of F. propinquus, as well as the impact of the F. rusticus expansion in the lake, were assessed through surveys from 2015 to 2018. The significance of the results is discussed with respect to the conservation status and the future management of native crayfishes in Lake Simcoe.

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.
