摘      要：The biosphere interacts and co-evolves with natural *** is known about the biosphere’s response to ancient environmental perturbations,but less about the biosphere’s influences on environmental change through earth ***,we discuss the roles of microbes in environmental changes during the critical Permian-Triassic(P-Tr)transition and present a perspective on future geomicrobiological *** biomarkers,stable isotopic compositions of carbon,nitrogen and sulfur,and mineralogical investigations have shown that a series of microbial functional groups might have flourished during the P-Tr transition,including those capable of sulfate reduction,anaerobic H2S oxidation,methanogenesis,aerobic CH4oxidation,denitrification,and nitrogen *** microbes may have served to both enhance and degrade the habitability of the Earth-surface environment during this *** integrated microbial roles have enabled the Earth’s exosphere to be a self-regulating system.
