Notes on the genus Usnea (lichenized Ascomycota, Parmeliaceae). V.

Plant and Fungal Systematics, 2023
Type material of twelve species of Usnea related to Asia and South Africa were studied and one species from North America is newly described. Holotype specimens of eight Chinese taxa described in 1975 were synonymized as follows: U. mengyangensis is lectotypified and synonymized with U. aciculifera. Usnea recurvata and U.

Nitrogen and Metal Ions Accumulation in Two Sensitive Himalayan Lichens From Western Nepal: A Reference for Ecosystem Health Monitoring

Journal of Chemistry, Volume 2025, Issue 1, 2025.
In this study, thalli nitrogen (N) and metal ions contents in the two fruticose lichens (Ramalina intermedia and Usnea cornuta) were quantified, which were collected from a pristine Himalayan forest of Shey Phoksundo National Park of western Nepal.

Diet of Andean Leaf‐Eared Mice (Phyllotis) Living at Extreme Elevations on Atacama Volcanoes: Insights From Metagenomics, DNA Metabarcoding, and Stable Isotopes

Ecology and Evolution, Volume 14, Issue 11, November 2024.
On the flanks of > 6000 m Andean volcanoes that tower over the Atacama Desert, leaf‐eared mice (Phyllotis vaccarum) live at extreme elevations that surpass known vegetation limits. We used a combination of metagenomics, DNA metabarcoding, and stable isotope analyses to investigate the diet of mice living in these extreme environments.

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.
