Green Evolution and Dynamic Adaptations Revealed by Genomes of the Marine Picoeukaryotes Micromonas [PDF]

Science, 2009
Picoeukaryotes are a taxonomically diverse group of organisms less than 2 micrometers in diameter. Photosynthetic marine picoeukaryotes in the genus Micromonas thrive in ecosystems ranging from tropical to polar and could serve as sentinel organisms for biogeochemical fluxes of modern oceans during climate change ...

Plastic leachates impair picophytoplankton and dramatically reshape the marine microbiome

Microbiome, 2022
Background Each year, approximately 9.5 million metric tons of plastic waste enter the ocean with the potential to adversely impact all trophic levels.

Distribution of ultraphytoplankton in the western part of the North Pacific subtropical gyre during a strong La Niña condition: relationship with the hydrological conditions [PDF]

Biogeosciences, 2013
The distribution of ultraphytoplankton was investigated in the western North Pacific Subtropical Gyre (NPSG) during La Niña, a cold phase of El Niño Southern Oscillation (ENSO).

Diapycnal Nutrient Fluxes and a Practical Assessment of the Biological Nutrient Trap in the North and South Atlantic Subtropical Gyres

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Diapycnal mixing supplies nutrients to the euphotic zone, which in oligotrophic regions may substantially support rates of new production. However, the consensus view that diapycnal nutrient fluxes support new production within the entire euphotic zone is challenged by deep living autotrophs that likely consume some, if not all, of the ...

Small Phytoplankton Community Composition Cycles Annually With a Coastal Bloom

Environmental Microbiology, Volume 27, Issue 11, November 2025.
The composition of the small phytoplankton community on the Northeast US Shelf changes gradually over the annual cycle. With a combination of analytical tools, we characterise these repeated transitions over a 9‐year period and relate them to changes in cell concentration.

Should I stay, or should I go: Anthropogenic noises disrupt early recruitment of subarctic invertebrates

Ecological Applications, Volume 35, Issue 7, October 2025.
Abstract Coastal subarctic systems are inhabited by bivalve and gastropods, which due to their lifecycle and longevity are reliable indicators of ecological alterations in the environment. Recent laboratory studies have shown that young life stages of invertebrates perceive natural sounds, and their settlement, behavior, and fitness could be altered by

The Partitioning of Carbon Biomass among the Pico- and Nano-plankton Community in the South Brazilian Bight during a Strong Summer Intrusion of South Atlantic Central Water

Frontiers in Marine Science, 2017
To investigate how pico- and nano-plankton respond to oceanographic conditions in the Southwestern Atlantic Ocean, we assessed the influence of a summer intrusion of the South Atlantic Central Water (SACW) on the spatial and vertical dynamics of ...

From temperate to polar waters: Transition to non‐cyanobacterial diazotrophy upon entering the Atlantic gateway of the Arctic Ocean

Limnology and Oceanography, Volume 70, Issue 10, Page 2924-2940, October 2025.
Abstract Nitrogen fixation, the microbial reduction of dinitrogen to ammonia, is increasingly recognized to occur in the Arctic Ocean. However, knowledge about the composition, biogeography, abundance, and ecology of nitrogen‐fixing organisms (diazotrophs) is poor.

Winter Dynamics of Phytoplankton and Micronutrients in the Southern Ocean

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract Combined observations of phytoplankton abundance, community structure, and trace metals in winter are scarce but crucial for understanding Southern Ocean biogeochemistry. This study provides the first early winter insights of phytoplankton‐micronutrient dynamics in the Indian sector of the Southern Ocean.
