01Narrative

Agrostis curtisii, the bristle bent, is a species of grass in the family Poaceae native to Eurasia. It is densely tufted, with hair like leaves and stems that grow up to 60 cm. Its spikelets are yellow-green in colour, and its lemmas are awned. The ligule is pointed. It has no rhizomes or stolons. Bristle bent flowers in the UK from June until July and is found typically on dry heaths and moors.Grasses of The British Isles By Tom Cope & Alan Gray, 2009 Botanical Society of the British Isles,

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 Alpagrostis setacea has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Alpagrostis setacea 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 Alpagrostis setacea 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 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.
