01Narrative

De bleke knuppelslak is een slakkensoort uit de familie van de knuppelslakken (Eubranchidae). De wetenschappelijke naam van de soort werd in 1842 voor het eerst geldig gepubliceerd door Alder & Hancock. In 2020 zijn verschillende soorten Eubranchus overgebracht naar het geslacht Amphorina.

05DNA & barcoding392 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 Amphorina pallida has left across the world's sequence archives.

09Environmental DNA392 detections

Where the DNA of Amphorina pallida 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.
