I'm having fun exploring ways to visualise the history of BINs in @boldsystems.bsky.social using #graphviz Below is the history of BOLD:AAH8697 which is a BIN highlighted by @rudolf-meier.bsky.social in doi.org/10.1111/cla..... Columns are time-slices and the coloured boxes are bins.

The top 10 flying insect clades rule the skies—but defy the rules. Weak or inverted latitudinal diversity gradients leave biogeographers puzzled. Entomologists? Mildly amused. www.biorxiv.org/content/10.1...

🚫 Farewell to species descriptions with consensus barcodes.
✨ Hello to Diagnostic Molecular Combinations (DMCs) for your taxonomic research
✅ State-specific
✅ Contrastive
✅ Publication-ready
Now even easier with the latest UITOTO, our updated user-friendly software; Preprint: doi.org/10.1101/2025...

UITOTO for taxonomy. Get your molecular diagnoses right without coding or breaking a sweat! Use state-specific, contrastive DMCs instead of fuzzy consensus barcodes!

Species- versus specimen-level congruence between DNA barcodes and morphology. Species-level dominates papers but specimen-level matters more for sample evaluation. Read more in "Illuminating Entomological Dark Matter with DNA Barcodes..." in Ann Rev Ent: www.annualreviews.org/content/jour...
