This study uses lipid hydrogen stable isotope probing to estimate archaeal generation times in hot spring sediments, finding decadal-scale rates in Yellowstone and slower rates in El Tatio.

This study measures microbial resuscitation and growth rates in deep permafrost using lipid-SIP, finding extremely slow initial growth and community restructuring within six months of thaw.

This study shows that lipid hydrogen isotope compositions in Sulfolobus acidocaldarius reflect growth water, offering a reliable hydrological proxy for extreme environments and planetary studies.

This paper evaluates Raman microspectroscopy as a method to measure microbial growth rates using deuterium incorporation, showing its reliability and comparison with nanoSIMS.

This study investigates how metabolism and growth conditions affect hydrogen isotope signatures in archaeal lipids, supporting their use as paleohydrological proxies.
