HERBIVORY AND DETRITIVORY BY THE LAND SNAIL CEPAEA NEMORALIS IN A TEMPERATE OLD FIELD
Bibliographic record
Abstract
The European banded wood snail (Cepaea nemoralis) has become widespread throughout the northeast United States and Canada, thriving in woodlands, roadsides, disturbed habitats, grasslands, and old fields. I used exclosure experiments to investigate the effect of snail herbivory on the biomass of Canada thistle (Cirsium arvense), a highly palatable forb species. I measured grass litter within exclosures to determine the effects o f detritivory on litter mass and used fecal analysis to determine the ratio of dead to live plant material in the diet. Snail exclosures had no effect on the total biomass of C. arvense or mass of grass litter. Live plants comprised approximately 10% of the overall snail diet with the remainder consisting of plant litter and soil. There was no clear seasonal trend in consumption of green material. However, snail herbivory increased with time from the last precipitation event, suggesting that snails consume live material to obtain water.
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.
