Forensic entomological case study and comparison of burned and unburned Sus scrofa specimens in the biogeoclimatic zone of northwestern Montana
Bibliographic record
Abstract
The goal of this experimental case study is to provide baseline rural forensic entomological data for the Interior Douglas-fir/Ponderosa Pine biogeoclimatic zone of Missoula County in Western Montana.The first hypothesis is that successional fauna will be similar to that of Dillon (1997) who conducted well-replicated forensic entomological studies in a similar biogeoclimatic zone located in British Columbia, Canada.The second hypothesis states that the burned and unbumed specimens will have different successional fauna specific to their physical states.The third hypothesis is that the insect successional pattern and species diversity on carcasses present in a mixed urban/rural and rural area will be distinct (Ternenyl997).This will provide the forensic investigator with a species diversity index indicating the abundance of urban and rural species in two biogeoclimatic zones of Montana.The first pig was burned with one gallon of gasoline and the second pig remained unbumt to act as the control.Phormia regina (Meigan) adults and immatures dominated among the order Diptera throughout the study until the post-decay stage when they co dominated with Lucilia illustris (Meigen).Protophormia terraenovae (Robineau-Desvoidy) also played a small role.During the post-decay stage Prochyliza brericornis (Melander) and Prochyliza xanthostoma (Walker) of the family Piophilidae made a significant contribution to the decomposition process.Among the Coleoptera Thanatophilus lapponicus (Herbst) and Necrodes surinamensis (Fabricius) were the most representative families.Many similarities were found between this study and that of Dillon (1997) in a similar biogeoclimatic zone.The parallels in decay rates and species diversity for these two studies conducted in an interior Douglas-fir and Douglas-fir/Ponderosa Pine Rocky Mountain biogeoclimatic zone cannot be accounted for as coincidence.The insect successional pattern was very similar for both pigs.The burned pig showed only a slight difference in the rate of decay and successional pattern.The families of insects involved in the decomposition process were similar for both the urban/rural and rural areas.The insects were typed to genus or species in this study.If applicable to human decedents, this baseline data will aid in the interpretation of Montana forensic anthropology and autopsy results to provide the medico-legal community with a more lucid explanation concerning time since death in forensic cases.

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.
