Peer Review #2 of "Multiplexed ISSR genotyping by sequencing distinguishes two precious coral species (Anthozoa: Octocorallia: Coralliidae) that share a mitochondrial haplotype (v0.1)"
Bibliographic record
Abstract
Background: Precious corals known as coralliid corals (Anthozoa: Octocorallia), play an important role in increasing the biodiversity of the deep sea.Currently, these corals are highly threatened because of overfishing that has been brought on by an increased demand and elevated prices for them.The deep sea precious corals Pleurocorallium elatius and Pleurocorallium konojoi are co-distributed in Japanese waters and have distinct morphological features: (1) the terminal branches of the colony form of P. elatius are very fine, while those of P. konojoi are blunt and rounded, (2) the autozooids of P. elatius are arranged in approximately four rows, while those of P. konojoi are clustered in groups.However, previous genetic analysis using mtDNA and nuclear DNA did not indicate monophyly.Therefore, it is important to clarify their species status to allow for their conservation. Methodology:We collected a total of 87 samples (60 of C. japonicum and 27 of P. konojoi) from around the Ryukyu Islands and Shikoku Island, which are geographically separated by approximately 1300 km.We used a multiplexed inter-simple sequence repeat (ISSR) genotyping by sequencing (MIG-seq) and obtained 223 SNPs with which to perform STRUCTURE analysis and principle coordinate analysis (PCoA).In addition, two relatively polymorphic mtDNA regions were sequenced and compared.Results: Pleurocorallium elatius and P. konojoi share a same mtDNA haplotype, which has been previously reported.However, MIG-seq analysis clearly distinguished the two species based on PCoA and STRUCTURE analysis, including 5% of species-specific fixed SNPs. Conclusion:This study indicated that P. elatius and P. konojoi are different species and therefore both species should be conserved separately.Our findings highlight the importance of the conservation of these two species, especially P. elatius, whose population has been dramatically depleted over the last 100 years.The study also demonstrated the effectiveness and robustness of MIG-seq for defining closely related octocoral species that were otherwise indistinguishable using traditional genetic markers (mtDNA and EF).

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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.
