Environmental and evolutionary factors favouring the coexistence of sarcosaprophagous Calliphoridae species competing for animal necromass
Bibliographic record
Abstract
1. Sarcosaprophagous flies from the Calliphoridae family provide clues about the circumstances of death in criminal investigations, and apparently occupy the same ecological niche because they depend on the same ephemeral resource, namely, carrion. 2. An empirical study was conducted in southeastern New Brunswick, Canada to identify differences in Hutchinsonian hypervolume/ecological niche that allow for competitive coexistence of calliphorid species. To do this, calliphorids were trapped for a calendar year in urban, periurban, and forest habitats. 3. About 20 576 calliphorid specimens distributed among 14 different species were collected. The composition of species assemblages changed with seasons, abiotic factors, habitats, and was related to the evolutionary history of species. Each species had a distinct centroid when their response to study variables was illustrated in canonical space, thus suggesting that their ecological niches differed. 4. Examining the Hutchinsonian hypervolumes of these forensically important insects is critical because it expands our knowledge of the factors regulating the activity of calliphorid species, thereby increasing our ability to use these insects in forensic investigations.

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.
