Lichen and Its Microbiome as an Untapped Source of Anti‐Biofilm Compounds

Chemistry &Biodiversity, Volume 22, Issue 4, April 17, 2025.
Lichens and their associated fungi give rise to the evaluation of several extracts and compounds against biofilms. ABSTRACT Lichen substances have been first described in the 1870s, and around 10 000 compounds have been isolated and characterized. Most of them have been evaluated for their activity on planktonic microorganisms (bacteria and fungi ...

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.
