In Italy, especially along the Apennine Chain, numerous active and inactive sulfuric acid
speleogenetic (SAS) caves have been documented in the last two decades. Here we …

Waters from an extensive sulfide-rich aquifer emerge in the Frasassi cave system, where
they mix with oxygen-rich percolating water and cave air over a large surface area. The …

Despite extremely starved conditions, caves contain surprisingly diverse microbial
communities. Our research is geared toward understanding what ecosystems drivers are …

The Frasassi Caves are hypogenic caves in central Italy, where H2S-rich groundwater flows
in the lowest cave level. Near the water table, the H2S is converted to sulfuric acid by biotic …

A stalagmite (FR16) from Frasassi Cave, located near the Adriatic coast of the Italian
peninsula, offers a 16 kyr petrographic and stable isotope record spanning from 112.8±1.5 …

A year-long study of the sulfidic aquifer in the Frasassi caves (central Italy) employed
chemical analysis of the water and measurements of its level, as well as assessments of the …

The oxidation of hydrogen sulfide (H 2 S) has led to the formation of some of the world's
largest caves through a process known as sulfuric acid speleogenesis (SAS). Here we …

Biogeochemical sulfur cycling in sulfidic karst systems is largely driven by abiotic and
biological sulfide oxidation, but the fate of elemental sulfur (S0) that accumulates in these …

Corrosion of limestone tablets in sulfidic ground-water: measurements and speleogenetic
implications Page 1 International Journal of Speleology 41(2) 149-159 Tampa, FL (USA) July …

This study provides the first report on a community of free-living ciliated protists from the
chemoautotrophic cave ecosystem of Frasassi, Italy. This subterranean groundwater …
