Abstract

fetched live from OpenAlex

Abstract We investigated the impact of different fluorescent marking powders on both survivorship and daily body condition, measured as mass/volume ratio, using adult mountain pine beetles,Dendroctonus ponderosaeHopkins (Coleoptera: Curculionidae: Scolytinae), in a laboratory study. Initial condition of the marked beetle groups did not differ from that of an unmarked group. However, beetles in better initial condition survived longer, thus validating our condition index. The condition but not the survivorship of mountain pine beetles was affected by the marking treatment. Overall, the condition of beetles declined over time. The condition of marked beetles decreased at a higher rate than that of unmarked beetles while alive but at a lower rate after death. This pattern of decreasing condition suggests that marked beetles lost water faster than unmarked beetles while alive, so unmarked beetles had more water to lose after death. Because reduced condition may affect optimal dispersal behaviour, we suggest that these effects be routinely examined and minimized in mark-recapture studies.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
