96 Recognizing cryptic species: investigations into the molecular relatedness and morphological diversity of the species of the red algal genus <i>plocamium</i> (plocamiales, florideophyceae)
Bibliographic record
Abstract
Small‐subunit ribosomal DNA (SSU) sequences used in combination with anatomical and morphological data have supported elevation of the Plocamiaceae to ordinal status. The Plocamiales currently includes two genera: the free‐living Plocamium Lamouroux; and the adelphoparasite, Plocamiocolax Setchell. Plocamium includes upwards of 40 species, which are widely distributed throughout the world's oceans. Most species are clearly defined anatomically and biogeographically. In this regard the type species, P. cartilagineum (L.) Dixon (type locality: reportedly Northern Europe), is an exception. Plocamium cartilagineum is considered cosmopolitan in distribution, with individuals varying in size, and in the number and habit of ramuli in their alternating series. We have sequenced the large‐subunit ribosomal DNA (LSU) for representatives of P. cartilagineum from France, Ireland, Norway and Scotland as well as isolates from Australia and the North Pacific. These data indicate that many cryptic species, four within Europe itself, are currently included within the concept of P. cartilagineum. We present molecular, biogeographical, ecological, and morphological/anatomical data characterizing these European forms and provide taxonomic revisions that reflect this diversity within P. cartilagineum.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
