Genomic Insights Into the Evolutionary History of Berardius Beaked Whales: Speciation Driven by Resource Specialization, Gigantism and Thermal Barriers?

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Understanding the diversity of our oceans is fundamental now more than ever as climate change and human activities put increasing pressure on marine species and ecosystems. Beaked whales (family Ziphiidae) are among the most poorly understood marine mammals, in part due to their affinity to offshore underwater canyons and prolonged diving ...

Microbial Controls on Dissolved Organic Nitrogen Cycling During Long‐Term Degradation Experiments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dissolved organic nitrogen (DON) is critical for marine microbial growth by providing carbon and nitrogen. Although DON is rapidly cycled, some compounds within this pool can persist for long‐periods of time. To better understand how DON is cycled by marine microorganisms, we conducted 548‐day incubations using surface‐derived dissolved ...

Diel vertical distribution of copepods during spring in the Northeast Atlantic Ocean

Frontiers in Marine Science
Vertical migration is a rather complex behavior by which multiple species of different sizes move from the meso- and bathy-pelagic zones, where they reside during day to avoid predators, to the epipelagic zone for feeding.

A novel and diverse group of Candidatus Patescibacteria from bathypelagic Lake Baikal revealed through long-read metagenomics

Environmental Microbiome, 2023
Background Lake Baikal, the world’s deepest freshwater lake, contains important numbers of Candidatus Patescibacteria (formerly CPR) in its deepest reaches.

The Deep‐Sea Preyscapes of Mammalian Top Predators

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.

Prokaryotic abundance and heterotrophic metabolism in the deep Mediterranean Sea

Advances in Oceanography and Limnology, 2010
A synthesis of field data carried out in the Mediterranean Sea are presented, aimed at contributing to the knowledge of three prokaryotic-mediated processes and their implications on the Carbon cycle.

Active Versus Passive eDNA Sampling Across Depths at a Tropical Fish‐Aggregating Device (FAD)

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Sampling at a fish aggregating device over three consecutive days using active and passive samplers detected a total of 39 fish operational taxonomic units (OTUs). Of these, 25 OTUs were shared between the two sampling approaches. The composition of detected OTUs varied among days and between sampler types.

An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Meso‐ to Submesoscale Variability of Particulate Carbon Export Captured by a Glider‐Camera System in the Northeast Atlantic During the APERO Campaign

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Between 9 June and 6 July 2023 a SeaExplorer glider equipped with an Underwater Vision Profiler (UVP6), surveyed frontal structures between a cyclonic and two anticyclonic eddies in the Northeast Atlantic as part of the APERO cruise (Assessing marine biogenic matter Production, Export and Remineralization: from the surface to the dark Ocean ...
