Microbial community structure in hadal sediments: high similarity along trench axes and strong changes along redox gradients [PDF]

, 2021
Hadal trench sediments are hotspots of biogeochemical activity in the deep sea, but the biogeochemical and ecological factors that shape benthic hadal microbial communities remain unknown.

Genomic Characteristics and Potential Metabolic Adaptations of Hadal Trench Roseobacter and Alteromonas Bacteria Based on Single-Cell Genomics Analyses

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 ...

A novel active deep-sea low-damage pressure-retaining organisms sampler

Frontiers in Marine Science, 2022
Capturing less damaged organisms samples is the basis for research on the biological communities, living environments, biological life compositions, and biological tissue structures of organisms livinin the deep seabed.

Revealing the full biosphere structure and versatile metabolic functions in the deepest ocean sediment of the Challenger Deep

Genome Biology, 2021
Background The full biosphere structure and functional exploration of the microbial communities of the Challenger Deep of the Mariana Trench, the deepest known hadal zone on Earth, lag far behind that of other marine realms.

Scavenging amphipods from the Wallaby-Zenith Fracture Zone: extending the hadal paradigm beyond subduction trenches [PDF]

, 2021
Our understanding of the ecology of the hadal zone (> 6000 m depth) is based solely on subduction trenches, leaving other geomorphological features, such as fracture zones, troughs, and basins, understudied.

Exponential growth of hadal science: perspectives and future directions identified using topic modelling [PDF]

, 2022
\ua9 2022 The Author(s).The hadal zone is a cluster of deep-ocean habitats that plunge to depths of 6000-11000 m below sea level. Research of the deepest marine zone has occurred on a disjunct timeline and slower than shallower zones.

Megafaunal Community Structure From the Abyssal to Hadal Zone in the Yap Trench

Frontiers in Marine Science, 2021
Hadal trenches remain one of the unexplored ocean ecosystems due to the challenges of sampling at great depths. It is still unclear how a faunal community changes from the abyssal to the hadal zone, and which environmental variables are the key impacting

Functional effects of the hadal sea cucumber Elpidia atakama (Echinodermata: Holothuroidea, Elasipodida) reflect small-scale patterns of resource availability [PDF]

, 2011
Holothuroidea represent the dominant benthic megafauna in hadal trenches (similar to 6,000-11,000 m), but little is known about their behaviour and functional role at such depths.

Distribution, composition and functions of gelatinous tissues in deep-sea fishes [PDF]

Royal Society Open Science, 2017
Many deep-sea fishes have a gelatinous layer, or subdermal extracellular matrix, below the skin or around the spine. We document the distribution of gelatinous tissues across fish families (approx.

The genome of a hadal sea cucumber reveals novel adaptive strategies to deep-sea environments

iScience, 2022
Summary: How organisms cope with coldness and high pressure in the hadal zone remains poorly understood. Here, we sequenced and assembled the genome of hadal sea cucumber Paelopatides sp.
