Our knowledge of circular replication-associated protein encoding single-stranded (CRESS) DNA virus diversity has increased dramatically in recent years, largely due to advances in high-throughput sequencing technologies. These viruses are apparently major virome components in most terrestrial and aquatic environments and it is therefore of interest to determine their diversity at the interfaces between these environments. Treated sewage water is a particularly interesting interface between terrestrial and aquatic viromes in that it is directly pumped into waterways and is likely to contain virus populations that have been strongly impacted by humans.

- Plants contribute a variety of carbon substrates to the soil, influencing soil chemistry and microbial communities, which can affect ecosystem functions like decomposition and nutrient transfer.
- A laboratory experiment tested eight carbon substrates of different chemical complexities over 92 days, revealing that the type of substrates significantly impacted soil microbial activity and decomposition processes.
- The addition of carbon substrates generally reduced plant growth compared to unamended soil, with varying effects depending on the specific substrates used, highlighting the importance of substrate identity and diversity in belowground ecosystems.
