Platorchestia platensis Griffiths et al. 2009
Bibliographic record
Abstract
Platorchestia platensis (KrØyer, 1845) BOLD:AAA2949 As Orchestia platensis KrØyer 1845, p. 304, fig. 2; Platorchestia platensis (KrØyer 1845), Bousfield 1982, p. 26. Material examined From the following sampling locations: 8C, 14A, 14C, 16B (see Table 1 and Figure 2 for further details). Distribution Found on similar sand beaches and under similar wrack piles as P. monodi. Found in single species samples (that is all three individuals analysed = BOLD:AAA2949), all on the northwest coast of Bermuda at Bailey ’ s Bay (8C), Tynes Bay (14C) and Lagoon Park (16B). One other sample at Tobacco Bay Park (14A) was a mixed sample containing one P. platensis and two P. monodi. Other locations on the northwest coast consisted of single species P. monodi, e.g. Coot Pond (14B), Gibbon ’ s Bay (7A) and Stovell ’ s Bay (5B). Remarks During this study this species was first recognized by its distinct molecular signature, which matched specimens identified as P. platensis from BOLD and GenBank. The same species is common on the Atlantic coast of North America, north of Charleston, North Carolina to New Brunswick (Radulovici 2012). Formalin-preserved specimens have not been checked for the possible occurrence of the two species of Platorchestia by morphological criteria, with the exception of sample 8C.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
