Ecomorphological correlates of microhabitat selection in two sympatric Asian Box Turtle species (Geoemydidae: <i>Cuora</i>)
Bibliographic record
Abstract
Closely related species that co-occur in homogeneous environments often possess differing morphologies, which can result in niche divergence that minimizes interspecific competition. In the present study, we examined the relationship between ecomorphological characteristics and microhabitat selection of two Asian box turtle species, the Keeled Box Turtle (Cuora mouhotii (Gray, 1862)) and the Indochinese Box Turtle (Cuora galbinifrons Bourret, 1940), that have sympatric distributions in the rainforest of Hainan, People’s Republic of China. We found that C. mouhotii had a relatively flat shell and preferred microhabitats with rock crevices and steep slopes in the field, whereas C. galbinifrons had a domed shell and was restricted to microhabitats of deciduous leaves under bamboo growing on gentle slopes. We conclude that morphological divergence allows the two Cuora spp. to use different microhabitats and, thereby, to successfully co-occur.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
