01Narrative

Amphipappus is a North American genus in the family Asteraceae. It is native to desert regions of the southwestern United States, in southern California, southern Nevada, Arizona, and southeastern Utah. There is only one known species Amphipappus fremontii. It is a shrub up to 60 cm tall. The flower heads are yellow and have both ray florets and disc florets. Its rounded clumps are scattered about dry, rocky areas. The species takes its scientific epithet, fremontii from John C. Frémont, and is known commonly by the names chaffbush or eytelia (in honor of artist Carl Eytel).

05DNA & barcoding2 eDNA hits

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 Amphipappus fremontii has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Amphipappus fremontii 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 Amphipappus fremontii 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.
