Leveraging Herbarium Records for a Niche Analysis of Ripariosida hermaphrodita (L.) Weakley & B. D. Poind. (Virginia mallow)
Bibliographic record
Abstract
Weedy and rare plant species that thrive in disturbed habitats, but with restricted ranges, present a unique field of ecological research.Native to the Great Lakes drainage and the Ohio, Kanawha, Susquehanna, and Potomac river basins, Virginia mallow, Ripariosida hermaphrodita (L.) Weakley & D.B. Poind.(Malvaceae), is one such pioneer species that, despite its weedy habit, is rare throughout its range from Indiana west to Pennsylvania and from Tennessee north to Ontario, Canada.This rhizomatous perennial can reach around four meters in one growing season and is cultivated as a biofuel crop in Eastern Europe.Virginia mallow yields perfect, white, terminal cymose panicle inflorescences for several months in late summer, maturing into capsule fruits.Recent molecular phylogenetic work has motivated the revision of Virginia mallow from Sida hermaphrodita (L.) Rusby to the newly monotypic Ripariosida.This work attempts to clarify the known extent of Virginia mallow through an ArcGIS niche analysis using georeferenced herbarium specimens collected over the last century and a half.248 wild collected and unduplicated records were assigned levels of geographic uncertainty from none to most: 51 specimens could not be georeferenced (Level 0), 83 specimens were georeferenced with a general locality statement (Level 1), 106 specimens were georeferenced with a precise locality statement (Level 2) and 7 specimens have GPS coordinates taken at the time of collection (Level 3).AnalysesTable of Contents I.

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.
