Large deep-sea zooplankton biomass mirrors primary production in the global ocean

open access: yesNature Communications, 2020
Zooplankton biomass in the dark ocean is thought to be low and weakly coupled to epipelagic primary production, but recent evidence suggests otherwise.

New information from fish diets on the importance of glassy flying squid (Hyaloteuthis pelagica) (Teuthoidea: Ommastrephidae) in the epipelagic cephalopod community of the tropical Atlantic Ocean [PDF]

open access: yes, 2007
Squids of the family Ommastrephidae are a vital part of marine food webs and support major fisheries around the world. They are widely distributed in the open ocean, where they are among the most abundant in number and biomass of nektonic epipelagic ...

Stable vectors in Moy-Prasad filtrations

open access: yes, 2016
Let k be a finite extension of Q_p, let G be an absolutely simple split reductive group over k, and let K be a maximal unramified extension of k. To each point in the Bruhat-Tits building of G_K, Moy and Prasad have attached a filtration of G(K) by ...

Flux‐driven evolution: Nitrogen fixation underlies contrasting stoichiometric strategies and genetic lineages in an open‐ocean copepod

open access: yesLimnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Variability in nutrient supply is a defining feature of oligotrophic oceans, yet how nutrient fluxes shape consumer physiology and population structure remains poorly resolved. Here, we examine how diazotrophic nitrogen fixation relates to stoichiometric metabolism and genetic structure in the widespread pelagic copepod Pleuromamma xiphias ...

Distribution of Virus-Infected Bacteria in the Western Equatorial Pacific. [PDF]

open access: yes, 2010
v. ill. 23 cm.QuarterlyViruses are generally considered an important agent of bacterial loss in diverse marine environments. However, the impact of viruses on bacteria is unknown in the western equatorial Pacific, where surface waters are warm and ...

The IceShark, an effective method for sampling plankton under sea ice

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 4, April 2026.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Potential and expression of carbohydrate utilization by marine fungi in the global ocean

open access: yesMicrobiome, 2021
Background Most of the research on the cycling of carbon in the open-ocean has focused on heterotrophic prokaryotes and eukaryotic phytoplankton, but the role of pelagic fungi remains largely enigmatic.

Upper Ocean Cycling of Iron South of the Polar Front: Biological Patterns and Processes

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Samples from the upper 300 m along the 52°S band, south of the Antarctic Polar Front in the Atlantic sector of the Southern Ocean, including a 3‐week monitoring of a persistent bloom, were analyzed to advance our understanding of iron cycling and supply to recurrent phytoplankton blooms.

Gut Microbiomes of Marine Zooplankton: Consequences for Host Performance, the Biological Carbon Pump, and Prokaryote Biogeography

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
Expected effects of zooplankton microbiota on the host and on the ecosystem. Stylized mesozooplankton holobiont (center) with arrows indicating respiration within the gut and export of faecal pellets and associated microbes. Orange bubbles summarise microbiome‐mediated consequences for host performance (digestive help, detoxification, vitamin ...
