Astract Coastal aquifers are under increasing threat due to excessive groundwater withdrawal, resulting in freshwater depletion, seawater intrusion, and land subsidence. To address these issues, the Sustainable Water Initiative for Tomorrow (SWIFT) Research Center in Suffolk, Virginia (USA), has been testing managed aquifer recharge (MAR) in the Potomac Aquifer of southeast Virginia since 2018. The Potomac Aquifer is hydraulic...

Summary Astrobiology is mistakenly regarded by some as a field confined to studies of life beyond Earth. Here, we consider life on Earth through an astrobiological lens. Whereas classical studies of microbiology historically focused on various anthropocentric sub‐fields (such as fermented foods or commensals and pathogens of crop plants, livestock and humans), addressing key biological questions via astrobiological approaches...

In terrestrial ecosystems, a large portion (20–80%) of the dissolved Si ( DS i) in soil solution has passed through vegetation. While the importance of this “terrestrial Si filter” is generally accepted, few data exist on the pools and fluxes of Si in forest vegetation and the rate of release of Si from decomposing plant tissues. We quantified the pools and fluxes of Si through vegetation and coarse woody debris ( CWD ) in a n...
