Variation of the auditory system in the Indian Gerbil, Tatera indica Hardwicke, 1807, (Muridae, Rodentia) from the east of Iran
Bibliographic record
Abstract
The Indian Gerbil (Tatera indica) is one of the most successful species in the east of Iran regarding the population size and distributional range. Many factors are effective in the success of this species, but the tympanic bulla and external ear with a special role in increasing sensitivity could be very important. In this study, these two characters were examined in 108 skulls of the adult Indian Gerbil from different localities in the east of Iran. The results of this study show an increasing trend in the volume of tympanic bulla and length of external ear from higher to the lower latitudes in accordance with Allen's rule. This increase is significant in the southeast Iran population. The increase of the body size in the Indian Gerbil was also documented from the northeast toward the southeast Iran. The negative correlation between the body size and latitude implies thermoregulatory response of the Indian Gerbil to the cold climate of the northeast Iran. It can also reflect food scarcity in desert areas of the southeast Iran comparing with the northeast areas inhabiting by the Indian Gerbil. This study proposed that an increase in auditory sensitivity would be advantageous for the gerbil's ability to escape predation, to mate, and to compete for resources.

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.
