Population and hierarchical genetic structure of <i>Badis badis</i> (Hamilton-Buchanan, 1822) in sub-Himalayan Terai region of West Bengal, India.
Bibliographic record
Abstract
Badis badis is a threatened ornamental freshwater fish in the Indian scenario. But the population genetic background of this ichthyofauna is largely unexplored in the eastern sub-Himalayan hotspot region of West Bengal state of India, known as the Terai. We have studied six populations from two major streams (Mahananda and Balason) of the region through RAPD fingerprinting. The allelic richness, Shannon’s Information index and a measure of evenness were calculated for each population. The SHE analysis revealed the change in diversity pattern in a spatial scale. Our results indicated that the allelic richness decreased and the evenness increased in the populations as the streams drained from higher to a lower altitude. The Nei’s genetic distance, genetic identity and UPGMA dendrogram revealed that the six populations formed two distinct groups. The principal component analysis also supported the UPGMA dendrogram. The pair-wise gene differentiation and gene flow between the populations showed the hierarchical genetic structure of Badis badis in the studied region.

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.
