05DNA & barcoding16 specimens

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 Alpheus edwardsii has left across the world's sequence archives.

▸ drag or hover over the strip to read any position — letter and how much it varies

Violet ticks below the strip = positions where individuals differ; flat = the species' unchanging signature. 74% of positions are identical in every specimen.

Variant network

Each circle is a barcode variant; bigger = more specimens, colour = region. Lines join the most similar variants and the tick marks count the mutations between them — a tight cluster is one “dialect”, a long line a more divergent lineage. Click a circle to list its actual specimens.

Closest relatives by DNA barcode

The species whose COI barcode is most similar to this one — a quick “who is this most like”. The percentage is how much the barcode differs; it approximates, but is not, the full evolutionary tree.

09Environmental DNA1 detections

Where the DNA of Alpheus edwardsii 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.

CHELSA 1981–2010, ~9 km grid, at location & month of 1 detection point · median with p10–p90 · reflects where sampling happened, not only the true niche

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.
