Anastrepta orcadensis, also known as Orkney notchwort, is a liverwort found in the United States, Canada, and widely in Europe. Its existence was first discovered on Ward Hill, on the island of Hoy, Orkney, Scotland by William Jackson Hooker in 1808."Bryology (mosses, liverworts and hornworts)" Royal Botanic Garden Edinburgh. Retrieved 15 May 2008."West Highland Mosses And Problems They Suggest" (January 1907) Annals Of Scottish Natural History 61 p. 46. Edinburgh. Retrieved 11 June 2008. It is commonly found in the northern hepatic mat on heather-covered slopes, woodland floors and on scree slopes in the Highlands and occurs elsewhere on the west and north coasts of the British Isles."Anastrepta orcadensis: Orkney Notchwort" (pdf) sleath.co.uk Retrieved 11 June 2008. In Alaska, it is most abundant on islands near the open sea and on inner islands at elevations above 300 metres (1500 ft)."Anastrepta orcadensis" sitkanature.org Retrieved 11 June 2008.

The complete instruction manualAnastrepta orcadensis 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
Genome size≈601 899 852 bp assembly estimate
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.

Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.

Where the DNA of Anastrepta orcadensis 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.
