The Characteristics and Potential Ecological Effects of the Exotic Crustacean Zooplankter Cercopagis Pengoi (Cladocera: Ceropagidae), a Recent Invader of Lake Erie
Bibliographic record
Abstract
The invasive zooplankter Cercopagis pengoi was recorded for the first time in Lake Erie during August 2001 following previous colonization of Lakes Ontario and Michigan. Cercopagis pengoi (Cladocera: Cercopagidae) is from the Ponto-Caspian region of Eurasia, as is a previous cercopagid invader, Bythotrephes longimanus. Cercopagis tolerates a wide range of salinities and temperatures, has many life history traits characteristic of a successful invader, and has previously invaded the Baltic Sea Cercopagis may affect native zooplankton populations and fish populations through both predation and competition, although the extent of these interactions is not yet known. More research regarding basic life history traits and ecology of Cercopagis is needed to assess the role it will play in Lake Erie.

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.
