Group:

Eudicot

Estimated genome size:

1.5 m

Size:

1.5 m

Distribution:

Maiden's Quiver Tree is restricted to desert mountainsides and arid ravines in South Africa (Richtersveld of the Northern Cape) and southern Namibia. Its distribution is concentrated within the Ai-Ais Richtersveld Transfrontier Park.

PromethION Sequencing Report:

Output:

379.51 Gigabases

Approximate N50:

12.36 kilobases

Draft Genome Assembly Statistics:

Genome Length:

11.21 Gigabases

BUSCO completeness score (single and duplicated genes):

99.9% [S: 92.7%, D: 6.8%]

Importance:

Aloidendron ramosissimum is threatened by plant theft, overgrazing, and ongoing habitat degradation. Its slow growth and low resilience mean disturbances, drought, and increased grazing pressure have long-term impacts, especially on juvenile survival. Climate change and possible mining activities are expected to further reduce its suitable habitat.

Species Card Details

Importance:

The Tugela labeo is a freshwater fish species endemic to South Africa. Currently listed as Vulnerable on the IUCN Red List, it is facing population decline due to a variety of recorded threats. It is primarily targeted in occasional recreational angling but also serves as an important species for subsistence fisheries in large dams and riverine habitats.
