Abstract

fetched live from OpenAlex

Unionid mussels have a unique lifecycle in which their larval phase must successfully attach to a suitable host (usually a fish) in order to metamorphose into their juvenile phase. Their hosts serve a dual purpose of providing nutrition and dispersing offspring. This thesis compiled current knowledge via a literature review on the larval hosts of all 55 unionid species in Canada, providing an updated library of unionid-host interactions and highlighting needs for future studies. Furthermore, it generated new knowledge on the reproductive ecology of the Eastern Elliptio (Elliptio complanata), the most abundant unionid species in Canada. This includes novel data for the reproductive timing of this species in Canada as well as some preliminary investigation on the impact of an invasive piscivore introduction on unionid reproduction. Collectively, this body of work provides valuable information that can be used by researchers and managers to conduct future research or inform conservation efforts.

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.

Not 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.
