Carrion Insects on Pig Carcasses at a Rural and an Urban Site in Nova Scotia
Bibliographic record
Abstract
Blow flies of the family Calliphoridae are significant insect colonizers of dead animal bodies and have proven useful in forensic investigations. The species composition and succession of insects on carcasses are affected by physical factors such as temperature, or exposure and also by the population biology of the flies. For accurate use of fly data in forensic cases it is important to establish a database of information on carrion insects for each different biogeographical area. This paper provides some baseline data for rural and urban areas of Nova Scotia over the summer period using pig carcasses under exposed, shaded and buried conditions. There was a great deal of overlap in species composition when the urban and rural sites were compared. Phormia regina was the most frequently encountered blow fly and it was present in exposed and shaded conditions at both sites. Lucilia illustris was also common at urban and rural sites while Phaenicia sericata was collected only at the urban site. Protophormia terraenovae was collected more often at the urban site. Only one species of blow fly, Cynomyopsis cadaverina, was recovered from buried pig carcasses. This result differs from most similar studies done. Some data are also included on the burying beetles and other insects associated with the carcasses.

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.
