01Narrative

Eurybia spectabilis, commonly known as the eastern showy aster, simply showy aster or purple wood aster, is an herbaceous perennial native to the eastern United States. It is present along the coastal plain of the U.S. where it is most often found growing in dry, sandy soils. Although it is not considered threatened due to its extensive range, it is locally endangered in many states. The flowers appear in the fall and show ray florets that are a violet-purple and yellow disc florets. It is one of the parent species of the hybrid Eurybia × herveyi.

05DNA & barcoding2 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 Eurybia spectabilis has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Eurybia spectabilis 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 DNA2 detections

Where the DNA of Eurybia spectabilis 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.
