Microbiomes of Hadal Fishes across Trench Habitats Contain Similar Taxa and Known Piezophiles [PDF]
mSphere, 2022 Hadal snailfishes are the deepest-living fishes in the ocean, inhabiting trenches from depths of ∼6,000 to 8,000 m. While the microbial communities in trench environments have begun to be characterized, the microbes associated with hadal megafauna remain

Genomic Characteristics and Potential Metabolic Adaptations of Hadal Trench Roseobacter and Alteromonas Bacteria Based on Single-Cell Genomics Analyses [PDF]
Frontiers in Microbiology, 2020 Heterotrophic bacteria such as those from the Roseobacter group and genus Alteromonas dominate the hadal zones of oceans; however, we know little about the genomic characteristics and potential metabolic adaptations of hadal trench-dwelling bacteria ...

Viral Infections Boost Prokaryotic Biomass Production and Organic C Cycling in Hadal Trench Sediments [PDF]
Frontiers in Microbiology, 2019 Hadal trenches are among the most remote and least explored ecosystems on Earth and can support high benthic microbial standing stocks and activities. However, information on the role of viruses in such ecosystems and their interactions with prokaryotic ...

Removal of dissolved organic carbon in the West Pacific hadal zones [PDF]
Nature CommunicationsThe deep oceans are environments of complex carbon dynamics that have the potential to significantly impact the global carbon cycle. However, the role of hadal zones, particularly hadal trenches (water depth > 6 km), in the oceanic dissolved organic ...

35 metagenomic datasets from the northern and southern parts of the Yap trench sediments [PDF]
Scientific DataThe hadal trench is the deepest part of the global ocean and harbors highly abundant microbial cells. However, the diversity and function of the majority of microbial communities in this part of the ocean are still unclear.

Genomic evidence on the distribution and ecological function of Pseudomonas in hadal zone [PDF]
BMC MicrobiologyThe hadal zone is the deepest region on Earth. It serves as a depositional zone for the sinking matter from surface ocean and continental margin, aided by its unique V-shaped structure.
