Application of cryopreservation to genetic analyses of a photosynthetic picoeukaryote community [PDF]

Gene, 2016
Cryopreservation is useful for long-term maintenance of living strains in microbial culture collections. We applied this technique to environmental specimens from two monitoring sites at Sendai Bay, Japan and compared the microbial diversity of photosynthetic picoeukaryotes in samples before and after cryopreservation.

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 ...

Diversity, Composition, and Activities of Nano- and Pico-Eukaryotes in the Northern South China Sea With Influences of Kuroshio Intrusion

Frontiers in Marine Science, 2021
Nano- and pico-eukaryotes play important roles in the diversity and functions of marine ecosystems. Warm, saline, and nutrient-depleted water that originates in the Kuroshio Current seasonally intrudes into the northern South China Sea (NSCS) from autumn

Distinct, Depth‐Stratified Communities of Heterotrophic, Mixotrophic, and Parasitic Dinoflagellates and Ciliates in the Subarctic Northeast Pacific Euphotic Zone

Journal of Eukaryotic Microbiology, Volume 73, Issue 2, March/April 2026.
ABSTRACT Dinoflagellates and ciliates are important grazers of primary production in the Northeast Pacific but knowledge of their taxonomic composition and depth‐distribution is limited. These organisms also display a variety of heterotrophic feeding modes including heterotrophy, mixotrophy, and parasitism.

Microbial‐mediated recycling constrains the contribution of primary production to export flux in an oligotrophic system

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract This study presents the first multi‐year assessment quantifying the contribution of primary production to vertical carbon flux in the ultra‐oligotrophic southeastern Levantine basin of the Mediterranean Sea. Depth‐integrated (0–180 m) daily primary productivity (PP) was 25% higher in the mixed winter period than in the stratified period (123 ...

Picoeukaryotes ☆

, 2009
Microorganisms play fundamental roles in marine ecosystems, sustaining food webs and driving biogeochemical cycles. Unicellular eukaryotes smaller than 2-3 um (picoceukaryotes) are recognized as important members of microbial assemblages in terms of both biomass and activity.

Temperature-driven biogeography of marine giant viruses infecting picoeukaryotes <i>Micromonas</i>. [PDF]

ISME Commun
Abstract Climate shapes the biogeography of microbial and viral communities in the ocean. Among abiotic factors, temperature is one of the main drivers of microbial community distribution. However, we lack knowledge on how temperature shapes the life history traits, population dynamics, and the biogeography of marine viruses.

The cycling of glycine betaine and homarine in marine microbial communities: Quantitative flux measurements and the role of competitive uptake inhibition

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract The flux of carbon through the labile dissolved organic matter (DOM) pool supports marine microbial communities and represents the fate of approximately half of marine net primary production (NPP). However, the behavior of individual chemical structures that make up labile DOM remain largely unknown.

Picoeukaryotic diversity and distribution in the subtropical-tropical South China Sea [PDF]

FEMS Microbiology Ecology, 2014
Little is known regarding the diversity and distribution of picoeukaryotes in the northwestern Pacific Ocean, although these organisms are vital components of their environment. Here, we used a culture-independent approach to assess the 18S rDNA diversity of picoeukaryotes at six sampling sites along a transcontinental section of the South China Sea ...
