01Narrative

Kostrzewa pstra – gatunek traw z rodziny wiechlinowatych (Poaceae). Jego zasięg obejmuje góry środkowej i południowo-wschodniej Europy od Alp po Kaukaz. W Polsce występuje tylko w wyższych partiach Karpat i Sudetów. W Tatrach jest pospolity.

05DNA & barcoding10 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 Festuca varia has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Festuca varia 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. Click any value below to see the underlying records and sources.

09Environmental DNA7 detections

Where the DNA of Festuca varia 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.
