Conservation Genetics of the Endangered Yellow Lampmussel (Lampsilis cariosa)
Bibliographic record
Abstract
Determining the genetic diversity of unionid populations is important for the preservation of the species and ecosystems in which they reside. The Yellow lampmussel, Lampsilis cariosa, is an endangered unionid found along the Atlantic Slope drainages in the United States and Canada. Along with many other North American unionid species, L. cariosa populations are declining. In order to enhance conservation efforts, the genetic structure and diversity of current populations must be examined. A sample of 178 individuals of L. cariosa from 20 populations in the Susquehanna and Delaware River drainages, and two different river populations in Maine were genotyped at the mitochondrial cytochrome oxidase subunit one (COI) gene and seven microsatellite loci. Haplotype genetic diversity for L. cariosa was low, while nucleotide diversity was high. Analysis of mtDNA showed significant population structure but lower than that of other mussel species. Our results indicate past gene flow among populations found in the Susquehanna and Delaware drainages with recent demographic expansion. As an endangered species with currently small population sizes, conservation efforts for L. cariosa should focus on protecting genetic diversity by preserving the largest populations in different drainages.

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.
