The Biogeography of a Disjunct Plant-Insect Relationship: Thimbleberry and Diastrophis kincaidii (Hymenoptera: Cynipidae) in the Great Lakes Region
Bibliographic record
Abstract
The clonal shrub thimbleberry (Rubus parviflorus) ranges throughout western North America and is disjunct to the northern Great Lakes region. Diastrophis kincaidii (Hymenoptera: Cynipidae) is an obligate gall wasp of thimbleberry that has long been known from western North America but has only been reported from the Great Lakes region since the early 1990s. It has been suggested that Diastrophis kincaidii was only recently introduced into the Great Lakes region sometime in the 1980s. We conducted a survey to determine the distribution of D. kincaidii and its parasitoids within the thimbleberry range in the Great Lakes region. We found that D. kincaidii is restricted to the colder and more xeric habitats within the Great Lakes thimbleberry range. Additionally D. kincaidii was found to have colonized isolated micro-habitats in the region were it attained high population densities. The inquiline community inhabiting D. kincaidii in the Great Lakes Region was similar to past reports. This community included species from eastern and western North America as well as two undescribed species. We suggest that D. kincaidii and its inquiline community have long been a part of the insect fauna of the Great Lakes region and is likely a remnant of an original connected pre-glacial continental thimbleberry population.

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.
