Argas persicus, also known as fowl tick or poultry tick, is a small soft-bodied tick that is found primarily on domestic fowl such as chickens, ducks, and geese. It was first recorded by Lorenz Oken in 1818 in Mianeh, Persia,"Argas Persicus - Fowl Tick (Invertebrate Species Summary)." WildPro. Ed. Debra Bourne. East Midland Zoological Society, Dec. 2013. Web. 15 Apr. 2017. and named Rhynochoprion persicum. Argas persicus appears yellowish-brown when starved and slatey-blue when engorged. They are found on an animal host, in cracks and crevices of buildings or in nests."Argas Persicus - Fowl Tick (Invertebrate Species Summary)." WildPro. Ed. Debra Bourne. East Midland Zoological Society, Dec. 2013. Web. 15 Apr. 2017."DPDx - Laboratory Identification of Parasitic Diseases of Public Health Concern." Centers for Disease Control and Prevention. Centers for Disease Control and Prevention, 03 May 2016. Web. 15 Apr. 2017. They are also carriers of the spirochete bacteria Borrelia anserina which causes avian spirochetosis, one of the most severe diseases affecting the poultry industry.Lisbôa, R. S., R. C. Teixeira, C. P. Rangel, H. A. Santos, C. L. Massard, and A. H. Fonseca. "Avian Spirochetosis in Chickens following Experimental Transmission of Borrelia Anserina by Argas (Persicargas) Miniatus." Avian Diseases. U.S. National Library of Medicine, June 2009. Web. 15 Apr. 2017. In addition to domestic fowl, A. persicus may also feed on humans, although an immunity has been acquired by some individuals.L. S. Fortescue (1924). "The Western Elburz and Persian Azerbaijan". The Geographical Journal. 63 (4): 301–315. .William Trager (1940). "A note on the problem of acquired immunity to argasid ticks".

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 Argas persicus 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.
Besides the big genome in the nucleus, cells carry a small, circular loop of DNA inside the cell's energy factories — the mitochondria. It is inherited almost only from the mother and is a leftover from ancient bacteria that moved into the cell. The mitochondrial markers above (ND*, COX, CYTB…) are read from exactly this loop. Outer ring = one strand, inner ring = the other.
The complete instruction manual Argas persicus 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.

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.

Range
Wildobservation + sensor
Human sightings and records, or camera-trap / sensor detections — someone (or a device) saw or captured the species in the wild.
Museum / Voucheredphysical evidence
Backed by a physical specimen — a herbarium sheet, sample or voucher held in a collection. “Vouchered” means supported by material evidence, not just an observation.

Where the DNA of Argas persicus 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?
Modelled climatemodelled
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.
