A limiting factor in the abundance of predatory phoretic mites (Acari: Macrochelidae): the seasonal abundance of their phorionts (dung beetles) in southern France
Bibliographic record
Abstract
The effects of host (dung beetles; Coleoptera: Scarabaeoidea) activity on seasonal abundance of phoretic mites (predatory macrochelids) were investigated in experimental dung pads under Mediterranean climatic conditions. Macrocheles robustulus and Macrocheles merdarius were collected only in spring and autumn. The most abundant macrochelids (Macrocheles glaber group; >90%) were rare in the hottest days and during winter. Mite abundance and dung beetle activity were correlated. The distribution (aggregate or not) of macrochelids in both pads and beetle traps was interpreted as a consequence of the availability of carriers that were found greatly affected by unfavourable meteorological conditions (temperature and rainfall). By their abundance and because they are opportunistic in the choice of host, the M. glaber group species can be considered the most efficient in coprophilous fly control.
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.

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.
