01Narrative

Echinocactus grusonii or Kroenleinia grusonii, popularly known as the golden barrel cactus, golden ball or mother-in-law's cushion, is a species of barrel cactus which is endemic to east-central Mexico. It is rare and endangered in the wild, where it is found near Mesa de León in the state of Querétaro, and in the state of Hidalgo. The population was critically reduced in the 1990s, by the creation of the Zimapán Dam and reservoir in Hidalgo. The cactus grows in volcanic rock on slopes, at altitudes around 1400 m.

05DNA & barcoding13 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 Kroenleinia grusonii has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Kroenleinia grusonii 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.

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.

09Environmental DNA13 detections

Where the DNA of Kroenleinia grusonii 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 10 detection points · 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.
