Developing a Systematic Sampling Framework for Terrestrial Gastropods in the Canadian Arctic
Bibliographic record
Abstract
Two protostrongylid parasites of Arctic ungulates, Umingmakstrongylus pallikuukensis and Varestrongylus eleguneniensis, were recently discovered in muskoxen on Victoria Island, Nunavut. The subsequent range expansion and increasing prevalence of these lungworms on the island suggested that the temperature-dependent rate of larval development in the gastropod intermediate host was no longer constraining their range to the Arctic mainland. Thus, to determine if the ecology of the gastropod intermediate host would facilitate or restrict the further expansion and establishment of these parasites, a better understanding of the distribution, diversity and abundance of terrestrial gastropods on Victoria Island was needed. However, a description of the efficacy of gastropod sampling techniques on the tundra was lacking. Therefore, my research describes the first strategic sampling framework for assessing gastropod ecology in the Arctic. Additionally, I analyzed the influence of extrinsic factors on gastropod capture rates and described new geographical records for the intermediate host, Deroceras laeve.

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.
