Updated checklist and zoogeographic remarks of benthic amphipods (Crustacea: Peracarida: Amphipoda) of two coastal lagoons in the western Gulf of Mexico
Bibliographic record
Abstract
Estuarine amphipods of the western Gulf of Mexico represent mostly eurythermal species. Sampling took place in Summer and Winter on seagrass beds, macroalgae and bare substrates, at 75 localities in Laguna Madre and 34 in Laguna de Tamiahua, Mexico, with a Renfro beam net and an otter trawl. A total of 19,398 specimens of 19 species were collected. Cymadusa compta was dominant in both lagoons with 63.4% of the total abundance. First records are 7 species for Laguna Madre and 11 species for Laguna de Tamiahua. A literature review updated the number of species from the 19 collected to 29. An analysis of the species’ distribution produced 3 zoogeographic patterns: Warm and Caribbean, Warm Temperate and Caribbean, and temperate. A hierarchical cluster analysis of the geographic distribution data of the 29 species produced 2 assemblages: one with an affinity for the warmer regions of the Gulf of Mexico, Caribbean Sea and Brazil, and another associated with the temperate conditions of the northern Gulf of Mexico, the eastern USA, Canada and Argentina, each group indicating a preference for either higher or lower water temperatures.

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.
