New study finds 19th-century wooden shipwrecks to be thriving habitats for deep-sea microbiomes frontiersin frontiersin
provide microbial habitats similar to naturally occurring geological seabed structures, reports a new study in. Wood fall and other hard surfaces are often islands of deep-sea life, but little is known about the microbial diversity of human-made habitats also found on the seafloor. Microbes are at the base of ocean food chains, and this is among the first research to show the impact of human activities—like shipwrecks—on these environments.
"Ocean scientists have known that natural hard habitats, some of which have been present for hundreds to thousands of years shape the biodiversity of life on the seafloor. This work is the first to show that built habitats impact the films of microbes coating these surfaces as well. These biofilms are ultimately what enable hard habitats to transform into islands of biodiversity.
The results showed that the type of wood had the greatest impact on bacterial diversity , although this was less influential for archaea and fungi. Microbial diversity also varied depending on the proximity to the wreck site.
