The complete mitochondrial genome of a new deep-sea hagfish Eptatretus sp. Nan-Hai (Myxinidae: Eptatretus) from the South China Sea

open access: yesMitochondrial DNA. Part B. Resources, 2020
In this study, the complete mitochondrial DNA sequence of a hagfish Eptatretus sp. Nan-Hai from a depth of 1000 m is presented. The complete sequence was determined using next-generation sequencing and long PCRs. The mitochondrial genome of Eptatretus sp.

Deep Sea Sedimentation

open access: yesEnvironmental Health Perspectives, 1974
An important problem in the study of microparticles in the marine environment, suspended in the water column or deposited as sediment on the ocean bottom, is the determination of provenance of the microparticles-where did they come from and by what processes were they transported to the sampling location?

Gambling in the deep sea [PDF]

open access: yesEMBO reports, 2006
For decades, the depths of the oceans have fascinated researchers. The discovery of strange creatures perfectly adapted to eternal darkness, high pressure, and other unusual conditions has raised enormous interest in how life emerged on Earth and how it flourishes in such extreme environments (Fig 1).

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

A chromosome-level genome assembly of a deep-sea starfish (Zoroaster cf. ophiactis)

open access: yesScientific Data, 2023
Understanding of adaptation and evolution of organisms in the deep sea requires more genomic resources. Zoroaster cf. ophiactis is a sea star in the family Zoroasteridae occurring exclusively in the deep sea.

Model-Based Underwater Image Simulation and Learning-Based Underwater Image Enhancement Method

open access: yesInformation, 2022
Due to the absorption and scattering effects of light in water bodies and the non-uniformity and insufficiency of artificial illumination, underwater images often present various degradation problems, impacting their utility in underwater applications ...

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.
