Unveiling Vertebrate Biodiversity in Arid and Semi‐Arid Terrestrial Ecosystems Through eDNA Metabarcoding at Savanna Waterholes

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Applying environmental DNA (eDNA) metabarcoding to samples from waterholes and their surroundings offers a promising approach for monitoring terrestrial vertebrates in semi‐arid and arid ecosystems, such as the southern African savannas. However, minimal guidance exists on key sampling design parameters for terrestrial ecosystems, which can ...
