SEASONAL ACTIVITY AND POPULATION FLUCTUATIONS OF A FREE-RANGING POPULATION OF THE RAT SNAKE PANTHEROPHIS OBSOLETUS INHABITING THE DALLAS ZOO, TEXAS
Bibliographic record
Abstract
In 1989 a mark–recapture study of a free-ranging urban population of Pantherophis obsoletus inhabiting the 38.5-ha grounds of the Dallas Zoo (Dallas, Texas) was undertaken and has continued until the present time. Seasonal activity occurred from late February through December. To understand and evaluate further the geographic variation of the seasonal activity of the eastern rat snake complex, we combined data on the seasonal activity of P. obsoletus from our long-term study with those from five other populations previously studied in Texas, Illinois, Kansas, and Maryland and Ontario, Canada. There was a highly significant linear reduction in length of the activity season with increasing latitude. We also describe significant changes in population size and body condition of the snakes during a 26-year study period at the Dallas Zoo and discuss possible factors causing the changes.

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.
