Distinct microbial nitrogen cycling processes in the deepest part of the ocean

mSystems
The Mariana Trench (MT) is the deepest part of the ocean on Earth. Previous studies have described the microbial community structures and functional potential in the seawater and surface sediment of MT.

Addressing false negatives and positives in eDNA studies

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 1977-2008, July 2026.
Abstract Environmental DNA (eDNA) has revolutionized the study of ecology and biodiversity, enabling species detection without direct observation in the environment. However, the implications of detection errors, specifically false positives and false negatives, are poorly reported in eDNA studies, significantly hindering our understanding of the ...

Seismic events drive pollution in Japan Trench hadal basins

Communications Earth & Environment
Hadal trenches, the deepest regions of the ocean, have long been considered remote sinks for organic matter and pollutants. However, recent evidence suggests these environments are more dynamic, influenced by both natural events and human activity.

Distribution of Tropical Vegetation From the Pliocene to the Anthropocene

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim The tropics harbour most of Earth's terrestrial biodiversity. This biodiversity has been influenced by cycles of climatic stability and instability over millions of years and may be affected by abrupt changes in the near future. We reconstructed the geographic distribution of the major tropical vegetation types (deserts, semi‐arid ...

Genomic evidence on the distribution and ecological function of Pseudomonas in hadal zone

BMC Microbiology
The 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.

Genomic and physiological properties of Anoxybacterium hadale gen. nov. sp. nov. reveal the important role of dissolved organic sulfur in microbial metabolism in hadal ecosystems

Frontiers in Microbiology
Hadal zones account for the deepest 45% of the oceanic depth range and play an important role in ocean biogeochemical cycles. As the least-explored aquatic habitat on earth, hadal ecosystems contain a vast diversity of so far uncultured microorganisms ...

Clear niche partitioning of nitrite-oxidizing bacteria from the bottom and the slope of Mariana Trench

Microbiome
Background The hadal zone, characterized by extreme hydrostatic pressure and geographic isolation, hosts microbial communities uniquely adapted to these harsh conditions.

D-amino acid metabolic versatility as a common adaptive strategy in the Mariana Trench microbiome

mSystems
Hadal trenches, the Earth’s deepest marine environments, harbor thriving microbial communities that promote the turnover of recalcitrant dissolved organic matter (RDOM) under extreme conditions.

Exploration of Carotenoid-Producing Microorganisms from the Kuril-Kamchatka Trench and Their Antioxidant Potential

Marine Drugs
Despite its extreme conditions, the hadal environment harbors abundant but largely underexplored microbial resources. In this study, samples from the Kuril-Kamchatka Trench (KKT) were enriched at low temperature using R2A and 2216E media.

35 metagenomic datasets from the northern and southern parts of the Yap trench sediments

Scientific Data
The 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.
