🦇 Two PhD positions available on our new ARC Discovery Grant: "From Diversity to Disease: Viral Ecology, Evolution and Persistence in Bats"

The project will investigate how viral diversity evolves and persists, with a particular focus on recently discovered henipaviruses in Australian flying foxes.

Soil viruses are important regulators of ecosystem function, but what are their roles in environments that face long-term degradation and restoration? In our paper published today in Nature Micro, we asked how soil viruses influence peatland recovery, and vice versa. www.nature.com/articles/s41...
Ecosystem health shapes viral ecology in peatland soils - Nature Microbiology
Metagenomics shows that viral diversity and community structure are shaped by geography and ecosystem health status, positioning viruses as unexpected players in peatland restoration.
