Evolutionary and acclimatory shifts in gene expression of Eurytemora affinis copepods reared in saline and freshwater conditions during laboratory experiments from 2011-2014
Bibliographic record
Abstract
To explore mechanisms of freshwater adaptation and distinguish between adaptive (evolutionary) and acclimatory (plastic) responses to salinity change, we examined genome‐wide patterns of gene expression between ancestral saline and derived freshwater populations of the Eurytemora affinis species complex, reared under two different common‐garden conditions (0 vs. 15 PSU). These data include the RNA-seq Illumina short paired end reads (101 base pairs) of 10 freshwater and 12 saline copepods Eurytemora affinis samples. The freshwater copepod samples were collected in Lake Michigan (Racine Harbor), while the saline copepods were collected in Baie de L'Isle Verte, St. Lawrence marsh, Quebec, Canada. These data have important implications for our understanding of the evolutionary and physiological mechanisms of range expansions by some of the most widespread invaders in aquatic habitats.

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.
