Artemisia rigida is a species of flowering plant in the aster family known by the common names scabland sagebrush and stiff sagebrush. It is native to the northwestern United States, in Washington, Idaho, and Oregon.Biota of North America Program 2014 county distribution map It has been recorded in western Montana but these sightings may have been misidentifications.McWilliams, Jack. 2003. Artemisia rigida. In: Fire Effects Information System, [Online]. U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory. Artemisia rigida is a small, spreading, deciduous shrub with many woody branches up to 40 centimeters long. The stems are gray and hairy.Artemisia rigida. Flora of North America. The leaves are up to 4 centimeters long and trident-shaped. They are grayish in color from their coat of silvery hairs. The plant is "mildly" to "pungently"Artemisia rigida. USDA FS International Institute of Tropical Forestry. scented. The flower heads are somewhat bell-shaped and measure about half a centimeter wide. They contain 4 to 8 yellow-red to red florets. Artemisia rigida grows in harsh substrates where few other plants survive. The soil is generally very shallow and covers bedrock. The bedrock is always basalt, never granite.Daubenmire, R. (1982). The distribution of Artemisia rigidia in Washington: A challenge to ecology and geology. Northwest Science 56(3) 162. The roots of the plant are within the shallow soil layer with some anchoring in rock fractures. There is also sometimes a layer of impermeable clay. The substrate commonly undergoes frost heaving, which breaks it up. On these unproductive sites, which occur in the Channeled Scablands, for example, this plant is a climax species. It is an indicator of scabland habitat. In the Columbia Basin it may dominate regions with thin soils, and have Sandberg's bluegrass as the main understory species.Native Grasslands and Shrub-steppe. USFWS Hanford Reach National Monument. Artemisia rigida provides food for wildlife because it is often the only plant exposed as the snow melts in the spring on mostly barren landscapes. Livestock also like it, especially the seedheads.

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 Artemisia rigida has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Artemisia rigida 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.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
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.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Wildobservation + sensor
Human sightings and records, or camera-trap / sensor detections — someone (or a device) saw or captured the species in the wild.

Where the DNA of Artemisia rigida 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.
Signal
Where its DNA was found
How strong is each trace?
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.
