Use of eDNA and conventional sampling methods to survey rock pool (gnamma) biodiversity on granite inselbergs

Austral Ecology, Volume 49, Issue 8, August 2024.
Environmental DNA sampling coupled with high‐throughput sequencing is increasingly recognized as a useful method for assessing biodiversity with potential applications in terrestrial environments. Rock pools on granite inselbergs support diverse aquatic communities, yet the application of eDNA to document their biodiversity is lacking.

Diversity of freshwater algal assemblages across the United States as revealed by DNA metabarcoding

Environmental DNA, Volume 6, Issue 1, January–February 2024.
Abstract As freshwater algae respond strongly to environmental conditions, algal communities are routinely used as indicators of aquatic health. Algal bioassessments have historically relied upon microscopy‐based identifications that are typically slow, expensive, taxonomically restricted, and inconsistent across analysts and time.
