<i>GRACILARIA</i> FROM THE GULF OF MEXICO, WITH SPECIAL EMPHASIS ON <i>GRACILARIA TIKVAHIAE</i> BASED ON TWO MOLECULAR DATASETS
Bibliographic record
Abstract
Despite a recent body of literature, the species of Gracilaria recognized for the Gulf of Mexico are still incompletely characterized, misidentified, and species limits not well defined due to huge morphological plasticity and overlapping habits. To better characterize these taxa and evaluate their taxonomic relationships, we provide a chloroplast‐encoded rbcL phylogeny encompassing primarily Gulf, western Atlantic, and Caribbean species. Our results indicate the need to resurrect older, validly published names currently placed in synonymy under other species of Gracilaria , and to describe new species. For Gracilaria tikvahia , in particular, a combination of DNA sequences [ rbcL , and internal transcribed spacer regions (ITS) of nuclear ribosomal DNA] from specimens collected across a wide biogeographic area (Nova Scotia, Canada, to Las Coloradas, Yucatan Peninsula) successfully promotes the integration and correlation of molecular phylogenies and morphology with biogeographic hypotheses.

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.
