Larval colonisation and recruitment in the Pacific giant salamander (<i>Dicamptodon tenebrosus</i>) in British Columbia
Bibliographic record
Abstract
Dicamptodon tenebrosus is a species at risk in Canada and little is known about its ability to recover from disturbance at any scale. I tested whether stream-dwelling larvae are capable of recolonising regions subjected to small disturbances (25- to 40-m artificially depleted reaches) within 1 year, and compared the contributions of larval dispersal and adult reproduction to repopulation of barren areas. Numerical recovery from depletions in these stream sections was predicted to take 6-42 months. Only 4-5% of larvae in reaches adjacent to the depleted zones became colonists in 13 months. Colonisation occurred both by upstream and downstream movements and by larvae of different sizes. Local reproduction appears to be a more effective means of repopulating an area than larval immigration. In one reproductive event, an adult female could provide an equal or greater number of colonists than is supplied by neighbouring stream sections holding 200+ larvae.
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.
