01Narrative

Guardiola rosei is a rare North American species of plants in the family Asteraceae. It is found only in northern Mexico in the states of Chihuahua, Durango, and Nayarit.Robinson, Benjamin Lincoln. 1899. Bulletin of the Torrey Botanical Club 26: 233Tropicos, Guardiola rosei B.L. Rob. Guardiola rosei is a perennial herb up to 40 cm tall, hairless and covered with wax so as to appear whitish. flower heads contain both ray flowers and disc flowers.

05DNA & barcoding1 specimens

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 Guardiola rosei has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Guardiola rosei 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.

09Environmental DNA1 detections

Where the DNA of Guardiola rosei 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
