Diet of the Prairie Rattlesnake, Crotalus viridis viridis, in southeastern Alberta
Bibliographic record
Abstract
The diet of the Prairie Rattlesnake, Crotalus viridis viridis, in a multiple land use area in southeastern Alberta was investigated by examining the gut contents of 20 road-killed individuals and the composition of eight scats recovered from sequestered individuals.All individuals yielding dietary data were adults.No data on the composition of the local small mammal community are available.The number of prey items per snake varied (gut contents: 0-4 items; scat samples: 1-3 items).Frequency of occurrence (individual prey items) was: Sagebrush Vole (Lagurus curtatus) -53% gut contents, 68% scats; Meadow Vole (Microtus pennsylvanicus) -38% gut contents, 8% scats; Olive-Backed Pocket Mouse (Perognathus maniculatus) -8% scats; Western Jumping Mouse (Zapus princeps) -8% scats; Richardson's Ground Squirrel (Spermophilus richardsonii) -8% scats; unidentified passerines -9% gut contents.Although individual rattlesnakes sometimes took more than one prey taxon (gut contents: 1-3 taxa; scat samples: 1-2 taxa), multiple prey items in a single gut were almost always of the same species, suggesting that individual rattlesnakes tend to exploit patches where colonial burrowing prey species are abundant.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
