01Narrative

Urera kaalae, opuhe, is a species of flowering plant in the nettle family, Urticaceae, that is endemic to the island of Oahu in Hawaii. It inhabits slopes and gulches in mesic forests at elevations of 300 -. Currently it is restricted to the southern and central parts of the Waianae Mountains. Associated plants include maile (Alyxia oliviformis), hame (Antidesma platyphyllum), Asplenium kaulfusii, Athyrium spp., āwikiwiki (Canavalia spp.), pāpala (Charpentiera spp.), akoko (Euphorbia spp.), poolā (Claoxylon sandwicense), ēlama (Diospyros hillebrandii), Doryopteris spp., iei.e. (Freycinetia arborea), manono (Hedyotis acuminata), Hibiscus spp., olopua (Nestegis sandwicensis), māmaki (Pipturus albidus), hala pepe (Dracaena spp.), ālaa (Pouteria sandwicensis), kōpiko (Psychotria spp.), heuhiuhi (Senna gaudichaudii), aiai (Streblus pendulinus), ōpuhe (Urera glabra), and maua (Xylosma hawaiiense). It is threatened by habitat loss.

05DNA & barcoding1 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 Urera kaalae has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Urera kaalae 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 DNA1 detections

Where the DNA of Urera kaalae 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.
