Copepod-Associated Gammaproteobacteria Respire Nitrate in the Open Ocean Surface Layers

Frontiers in Microbiology, 2018
Microbial dissimilatory nitrate reduction to nitrite, or nitrate respiration, was detected in association with copepods in the oxygenated water column of the North Atlantic subtropical waters.

No evidence of Calanus reorganization across three Northeast Atlantic transects during 30 years of monitoring

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Reports have suggested dramatic shifts in the calanoid assemblage of the Northeast Atlantic, with warm‐water species expanding northwards at the expense of cold‐water congeners. This is considered a serious threat to lipid‐fueled higher trophic levels, as warm‐water copepods are typically smaller with lower lipid content.

Diversity and Distribution of Mesozooplankton in the Coastal Southwestern Mediterranean Alboran Sea, during Summer: What Are the Driving Factors?

Journal of Marine Science and Engineering
The southern Alboran Sea is a dynamic ecosystem and is highly influenced by Atlantic waters. Unfortunately, despite the importance of the mesozooplankton in this ecosystem, the number of studies on this ecosystem is low.

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

Limnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Distribution of mesozooplankton biomass in the global ocean [PDF]

, 2012
Mesozooplankton are cosmopolitan within the sunlit layers of the global ocean. They are important in the pelagic food web, having a significant feedback to primary production through their consumption of phytoplankton and microzooplankton.

Dynamic factor analysis of mesozooplankton variability in the Gulf of Cádiz

Frontiers in Marine Science
Mesozooplankton plays a key role in pelagic ecosystems, acting as an intermediate trophic link and a modulator of biogeochemical cycles. However, its dynamics remain poorly understood on the northeastern shelf of the Gulf of Cádiz, a highly productive ...

Seasonal variation of mesozooplankton biomass, abundance and copepod grazing in the central Cantabrian Sea (southern Bay of Biscay)

Scientia Marina, 2006
Size fractionated mesozooplankton biomass, abundance and copepod grazing were investigated over an annual cycle (1998) at two stations off Cudillero (central Cantabrian Sea). Mesozooplankton biomass was higher in summer/early autumn, reaching ~3000 mg dw

Cyanobacteria Sustain Deep Ocean Carbon Sequestration Despite Eukaryotic Loss

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract The biological carbon pump exports phytoplankton‐derived organic carbon to the deep ocean, regulating long‐term carbon sequestration and climate. Yet how phytoplankton community composition controls the magnitude and efficiency of this process remains poorly understood.

Seasonal patterns in plankton communities in a pluriannual time series at a coastal Mediterranean site (Gulf of Naples): an attempt to discern recurrences and trends

Scientia Marina, 2004
The annual cycle of plankton was studied over 14 years from 1984 to 2000 at a coastal station in the Gulf of Naples, with the aim of assessing seasonal patterns and interannual trends.
