Life after death in the pelagic: Non‐predatory zooplankton mortality and the “ghost carbon pump”

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract The biological carbon pump is traditionally framed as a trophically mediated process in which zooplankton mortality is attributed mainly to predation, routing carbon through fecal pellets and higher trophic levels before export. Increasing evidence, however, shows that nonpredatory mortality—caused by different environmental stressors—accounts

Signature of the anthropogenic impacts on the epipelagic microbiome of the North-Western Adriatic Sea (Mediterranean Sea)

open access: yesFrontiers in Marine Science
IntroductionIn our paper, we explored the impact of different anthropogenic stressors, namely, mussel farming, methane extraction platforms, and summer mass tourism, on the epipelagic microbiomes of the North-Western Adriatic Sea.MethodsBy 16S rRNA gene ...

Co-occurrence analysis of microbial taxa in the Atlantic Ocean reveals high connectivity in the free-living bacterioplankton

open access: yesFrontiers in Microbiology, 2016
We determined the taxonomic composition of the bacterioplankton of the epipelagic zone of the Atlantic Ocean along a latitudinal transect (51°S – 47°N) using Illumina sequencing of the V5-V6 region of the 16S rRNA gene and inferred co-occurrence networks.

Genericity and contragredience in the local Langlands correspondence [PDF]

open access: yes, 2012
We prove the recent conjectures of Adams-Vogan and D. Prasad on the behavior of the local Langlands correspondence with respect to taking the contragredient of a representation.

The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 643-659, May 2026.
ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

Metabolic Regulation of Dimethylsulfoniopropionate Cleavage and Dimethyl Sulfide Production in Halomonas sp. D47

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
Dimethylsulfoniopropionate (DMSP) is a major marine organosulfur compound central to climate‐relevant dimethyl sulfide (DMS) production. In Halomonas sp. D47, DMSP catabolism is revealed to be coordinated by two transcriptional regulators, AcuR and AcuZ, which control gene expression by sensing DMSP and its metabolites.

Brain Morphology and Quantitative Assessment of Sensory Brain Areas in Southern Bluefin Tuna, Thunnus maccoyii (Scombridae, Teleostei)

open access: yesJournal of Comparative Neurology, Volume 534, Issue 4, April 2026.
The absolute and relative volume of major sensory and integrative brain regions of the southern bluefin tuna Thunnus maccoyii are examined using magnetic resonance imaging (MRI). A dominant cerebellum projects into the midbrain ventricular space, while the optic tectum represents a smaller proportion of total brain volume than previously estimated ...
