Eurybia integrifolia, (formerly Aster integrifolius) commonly called the thickstem aster, is an herbaceous perennial in the family Asteraceae. It is native to the western United States where it grows primarily in the Rocky Mountains, the Great Basin, and the Sierra Nevada in Washington, Idaho, Montana, Wyoming, Utah, Oregon, Nevada, and California.

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 Eurybia integrifolia has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualEurybia integrifolia 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 DNA3 detections
Where the DNA of Eurybia integrifolia 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.
