What lies beneath--discovering the hidden story of plant roots: root growth strategies of wetland plants in northern Ontario along a gradient of growing season length.
Bibliographic record
Abstract
Root growth strategy can be classified as multi-season (winter-surviving) or single-season (fallsenescing). This study investigated the relationship of wetland plant species with multi-season roots (sMSR) and species with single-season roots (sSSR) to soil temperature across a climatic growing season gradient. Study sites were in Lake Superior Provincial Park and Manitoulin Island. In fall 2013, root ingrowth cores were installed in soil. Root length and shoot dry mass were measured at harvests from spring 2014 to spring 2015. Results showed that soil and air temperature differed by geographic zone; Lake Superior Provincial Park demonstrated lower temperatures than Manitoulin Island. Soil temperature affected root length (positively) and shoot dry mass (negatively). Root growth strategy had a nearly significant relationship with ratio of spring to maximum shoot dry mass—greater for sMSR than sSSR; and a significant relationship with relative late season shoot dry mass change—decreasing for sMSR and increasing for sSSR.

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.
