Escobaria tuberculosa ist eine Pflanzenart in der Gattung Escobaria aus der Familie der Kakteengewächse (Cactaceae). Das Artepitheton tuberculosa stammt aus dem Lateinischen, bedeutet ‚höckerig‘ und verweist auf die gehöckerten Triebe der Art.Urs Eggli, Leonard E. Newton: Etymological Dictionary of Succulent Plant Names. Springer, Berlin/Heidelberg 2010, ISBN 978-3-642-05597-3, S. 245. Englische Trivialnamen sind „Arizona Pincushion“ und „Cob Cactus“.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Pelecyphora tuberculosa has left across the world's sequence archives.

The complete instruction manualPelecyphora tuberculosa carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

Where the DNA of Pelecyphora tuberculosa was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
