La Joubarbe des montagnes est une espèce de plantes herbacées vivace de la famille des Crassulacées. C'est une plante grasse de montagne poussant entre 900 m et plus de 2 500 m dans les massifs du sud de l'Europe. En Provence, cette plante robuste avec des fleurs en étoiles roses qui s'épanouissent en juillet/août devient rare. Cette espèce de joubarbe existe sur les crêtes de la montagne Sainte-Victoire entre 940 m et 1 010 m ; elle est à protéger absolument du fait de sa rareté dans cette région, elle y fleurit en juillet lorsque la sécheresse et la canicule ne sont pas trop sévères, sinon les boutons floraux ne s’épanouissent pas et se dessèchent. Elle n'existe pas dans le massif de la Sainte-Baume ni au Mont Aurélien, elle existe dans la région des gorges du Verdon. Les feuilles de la Joubarbe des montagnes sont parfois parasitées par les larves du Syrphe Cheilosia caerulescens.

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 Sempervivum tectorum 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.
The complete instruction manual Sempervivum tectorum 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.

Origin
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.
Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Sempervivum tectorum 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.
Signal
Where its DNA was found
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.
