Maintenance of endemic Dendroctonus ponderosae populations through interactions with a secondary bark beetle, Pseudips mexicanus.
Bibliographic record
Abstract
Endemic Dendroctonus ponderosae are often found inhabiting weakened lodgepole pine (Pinus contorta var. latifolia) in western Canada previously attacked by the little known bark beetle Pseudips mexicanus. Interactions between the two species have not been elucidated, so three studies were conducted. The first examined the life history of P. mexicanus, describing developmental characteristics. The second explored the interaction between the two species and found the D. ponderosae attacking ephemeral hosts previously occupied by P. mexicanus do so in greater densities with earlier offspring emergence when compared to hosts D. ponderosae attacked alone. P. mexicanus may alter host chemistry, allowing D. ponderosae to be more successful when compared to trees D. ponderosae attacked alone. The third study investigated the attraction of D. ponderosae to P. mexicanus-produced volatiles, revealing no response by D. ponderosae. The scope of this work contributes to the understanding of bark beetle ecology in the lodgepole pine ecosystem.--P.ii

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.
