Study Examines the Role of Deep-Sea Microbial Predators at Hydrothermal Vents

A view of the Apollo Vent Field at the northern Gorda Ridge, where samples were collected by the ROV Hercules for studying microbial predators. “Our findings provide a first estimate of protistan grazing pressure within hydrothermal vent food webs, highlighting the important role that diverse deep-sea protistan communities play in deep-sea carbon cycling,” according to the paper, Protistan grazing impacts microbial communities and carbon cycling ad deep-sea hydrothermal vents published in the Proceedings of the National Academy of Sciences (PNAS). Obtaining baseline measurements “is increasingly important as these habitats are being looked at for deep-sea mining or carbon sequestration.
