Genome size estimates for two important freshwater molluscs, the zebra mussel (<i>Dreissena polymorpha</i>) and the schistosomiasis vector snail (<i>Biomphalaria glabrata</i>)
Bibliographic record
Abstract
The haploid genome sizes of two important molluscs were assessed by Feulgen image analysis densitometry. The genome size of the zebra mussel (Dreissena polymorpha), a prolific invader of North American lakes, was estimated to be 1C = 1.70 +/- 0.03 pg, and that of the freshwater snail Biomphalaria glabrata, the predominant intermediate vector of the human parasite Schistosoma mansoni, was estimated at 0.95 +/- 0.01 pg. These estimates will be important in future efforts in molluscan genomics, which at present lags far behind work being carried out with vertebrate and arthropod models. B. glabrata in particular, which has one of the smallest known gastropod genomes, is recommended as a highly suitable target for future genome sequencing.
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.
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.
