Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]

open access: yes, 2016
Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...
