01Narrative

The yellow-shouldered amazon (Amazona barbadensis), also known as the yellow-shouldered parrot, is a parrot of the genus Amazona that is found in the arid areas of northern Venezuela, the Venezuelan islands of Margarita and La Blanquilla, and the island of Bonaire (Caribbean Netherlands). It has been extirpated from Aruba and introduced to Curaçao.

05DNA & barcoding3 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 Amazona barbadensis has left across the world's sequence archives.

06Genome at a glanceGoaT

The complete instruction manual Amazona barbadensis 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 size1 545 240 000 bp

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).

09Environmental DNA2 detections

Where the DNA of Amazona barbadensis 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?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
