Major contribution of prokaryotes to carbon fluxes in the pelagic microbial food webs of the Mediterranean Sea

Advances in Oceanography and Limnology, 2016
In this study, we carried out dilution experiments at the surface and in the mesopelagic and bathypelagic layers at 15 sites in the Mediterranean Sea that covered a wide range of trophic conditions.

Potential Impacts of Climate Interventions on Marine Ecosystems

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...

Geographic distribution of archaeal ammonia oxidizing ecotypes in the Atlantic Ocean

Frontiers in Microbiology, 2016
In marine ecosystems, Thaumarchaeota are most likely the major ammonia oxidizers. While ammonia concentrations vary by about two orders of magnitude in the oceanic water column, archaeal ammonia oxidizers (AOA) vary by only one order of magnitude from ...

Dynamic Sinking and Surface‐Area Based Decay Modeling Reduce Estimates of Gelatinous Zooplankton‐Mediated Carbon Export to the Deep Sea

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Gelatinous zooplankton (GZ) have been proposed as a potentially important but largely overlooked contributor to the biological carbon pump. However, estimates of GZ‐derived carbon transfer efficiency to the ocean floor reflect uncertainties in key parameters that govern carbon export, leading to contrasting interpretations of the role of GZ in

Hiding in Plain Sight: Elopomorph Larvae Are Important Contributors to Fish Biodiversity in a Low-Latitude Oceanic Ecosystem

Frontiers in Marine Science, 2020
Leptocephalus larvae of elopomorph fishes are a cryptic component of fish diversity in nearshore and oceanic habitats. However, identifying those leptocephali can be important in illuminating species richness in a region.

Climate Change, Local Harvests and Marine Contamination: A Perspective on Cetacean Populations and Coastal Whaling Communities

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Cetaceans are indicators of ocean health, influence marine ecosystem dynamics and hold socio‐economic importance for coastal whaling communities. Yet whale–whaler relationships remain poorly understood and are increasingly compromised under the triple planetary crisis of climate change, biodiversity loss and pollution. Here, we briefly outline

Abundance and activity of Chloroflexi-type SAR202 bacterioplankton in the meso- and bathypelagic waters of the (sub)tropical Atlantic

, 2008
The contribution of Chloroflexi-type SAR202 cells to total picoplankton and bacterial abundance and uptake of d- and l-aspartic acids (Asp) was determined in the different meso- and bathypelagic water masses of the (sub)tropical Atlantic (from 35°N to 5 ...

DNA stable‐isotope probing reveals potential key players for microbial decomposition and degradation of diatom‐derived marine particulate matter

MicrobiologyOpen, 2020
Microbially mediated decomposition of particulate organic carbon (POC) is a central component of the oceanic carbon cycle, controlling the flux of organic carbon from the surface ocean to the deep ocean.

Micronektonic community composition and trophic structure within the bathypelagic zone in the eastern Gulf of Mexico

, 2006
The Earth\u27s most extensive living space is found in the bathypelagic zone of the oceans, yet research in these areas is scant. The micronekton of the bathypelagic zone in the eastern Gulf of Mexico (EGOM) was investigated with the goals of comparing ...
