Abstract
Kurczewski, Frank E. 2000.History of White Pine (Pinus strobus)/oak (Quercus spp.) savanna in southern Ontario, with particular reference to the biogeography and status of the Antenna-waving Wasp, Tachysphex pechumani (Hymenoptera: Sphecidae).Canadian Field-Naturalist 114(1): 1-20.The entry of Tachysphex pechumani into southwestern Ontario, estimated at 8000 to 6500 yr B. P. (before the present), is linked to ameliorated climate, Great Lakes low water levels, exposed sandy shores and land bridges, and abundance of White Pinegraminoid-herb savanna.Its putative historical geographic distribution in the region is traced to late 18th and early 19th century oak/pine woodland; scrubby, bushy, shrubby and burnt oak/pine vegetation; oak, oak-hickory and oak-pine plains; and White Pine-Red Pine plains.The current geographic distribution of the Antenna-waving Wasp, a rare insect on sandy soils in southwestern Ontario, is limited to three widely separated populations: (1) north of Lake Erie near Long Point; (2) southern shore of Lake Huron near Pinery Provincial Park; and (3) south of Georgian Bay on Canadian Forces Base Borden.Reforestation, fire suppression, excessive off-road motorized vehicular traffic, and insecticide use are threats to these populations.

How this classification was reachedexpand
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.
