Fleas associated with the northern pocket gopher (<i>Thomomys talpoides</i>) in Elbert County, Colorado
Bibliographic record
Abstract
We collected 532 fleas, 526 of which were Foxella ignota ignota, from 247 northern pocket gophers, Thomomys talpoides, in Elbert County, Colorado, over 13 months. Other fleas included 1 Hystrichopsylla dippiei ssp., 3 Spicata rara, 1 Oropsylla idahoensis, and 1 female flea tentatively identified as Oropsylla (Opisocrostis) sp. These are new records for H. dippiei ssp. and S. rara in Elbert County. Fleas were cleared using standard methods and were placed on microscope slides in Canada balsam. The number of fleas per host ranged from 0 to 26. The highest median number of fleas per host (n = 5) was in May with a low median (n = 0) in August. Mean intensity and relative density of fleas peaked in April and May, respectively. Total flea abundance peaked from April through July. Approximately 72% of the male gophers (N = 99) were infested with fleas, whereas 57% of the females (N = 148) had fleas. Flea abundance on male gophers did not decrease nor did flea abundance on females increase as would be expected if flea breeding were influenced by hormones of the host. We suggest further randomized studies of fleas on T. talpoides to investigate parasite abundance throughout the year.
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.
