Thermal Selection of Microbial Communities and Preservation of Microbial Function in Guaymas Basin Hydrothermal Sediments.

ABSTRACT: The Guaymas Basin in the Gulf of California is characterized by active seafloor spreading, hydrothermal activity, and organic matter accumulation on the seafloor due to high sedimentation rates. In the hydrothermal sediments of Guaymas Basin, microbial community compositions and coexistence patterns change across steep gradients of temperature, potential carbon sources, and electron acceptors. Nonmetric multidimensional scaling and guanine-cytosine percentage analyses reveal that the bacterial and archaeal communities adjust compositionally to their local temperature regime. Functional inference using PICRUSt shows that microbial communities consistently maintain their predicted biogeochemical functions in different sediments. Phylogenetic profiling shows that microbial communities retain
