01Narrative

Eurybia paludosa, commonly known as the southern swamp aster, is an herbaceous perennial in the family Asteraceae. It is native to the southeastern United States where it is confined to the Carolinas and the states of Georgia and Florida. It is generally confined to moist soils, though it can occasionally be found on sand hills along the coastal plain. The southern swamp aster is often confused with the closely related southern prairie aster (Eurybia hemispherica), though they do not occur in the same habitats or geographical areas. Its flower heads emerge in the late summer through fall and show deep lavender to purple rays with yellow centres.

05DNA & barcoding11 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 paludosa has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Eurybia paludosa 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 DNA10 detections

Where the DNA of Eurybia paludosa 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.
