Major contribution of particle‐associated microbes to deep‐sea organic carbon degradation
Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract The biological carbon pump mediates the export of particulate organic carbon from the euphotic zone to the deep ocean, where it provides the base of the food web. Although deep‐sea microbial metabolism is considered to be largely associated with macroscopic particles, such as marine snow, the specific contribution of particle‐associated ...

Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT The Mediterranean common dolphin (Delphinus delphis) presents an enigmatic natural history during the past centuries. Widely prevalent in the 19th and early 20th centuries, it faced a significant decline across most of the basin by the late 1960s caused by multiple anthropogenic threats, including culling, bycatch, prey depletion, and habitat ...

An Acidogenic Carotenoid in a Bathypelagic Nemertean Worm [PDF]
Nature, 1954 CERTAIN brightly coloured littoral nemerteans contain carotenoids, and it is likely that most deep-sea species of similar coloration likewise store this class of biochrome1.

Diel vertical distribution of copepods during spring in the Northeast Atlantic Ocean
Frontiers in Marine ScienceVertical 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.

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.

Estuarine Nitrifiers: New Players, Patterns and Processes [PDF]
, 2010 Ever since the first descriptions of ammonia-oxidizing Bacteria by Winogradsky in the late 1800s, the metabolic capability of aerobic ammonia oxidation has been restricted to a phylogenetically narrow group of bacteria.

Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT Studies of cetacean diving behavior in multiple locations in different ocean basins allow for an assessment of variability within and among populations. We examine foraging dive behaviors of goose‐beaked whales (Ziphius cavirostris) and dense‐beaked whales (Mesoplodon densirostris) using data from 132 tagged whales in seven locations in the ...
