Ultraviolet Radiation Stimulates Activity of CO2 Concentrating Mechanisms in a Bloom-Forming Diatom Under Reduced CO2 Availability

open access: yesFrontiers in Microbiology, 2021
The diatom Skeletonema costatum is cosmopolitan and forms algal blooms in coastal waters, being exposed to varying levels of solar UV radiation (UVR) and reduced levels of carbon dioxide (CO2).

Full‐year in situ imaging reveals fine‐scale habitat differences among salp and doliolid life stages

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Doliolids and salps are pelagic tunicates that reproduce both asexually and sexually during their life history, occasionally forming massive blooms (> 1000 ind. m−3) that can clear large volumes of water daily. Although blooms of doliolids and salps are often associated with pulses of primary productivity, little is understood about their life

Isolation and Characterization of Glutamine Synthetase from the Marine Diatom Skeletonema costatum [PDF]

open access: yesPlant Physiology, 1996
Abstract Two peaks of glutamine synthetase (GS) activity were resolved by anion-exchange chromatography from the marine diatom Skeletonema costatum Grev. The second peak of activity accounted for greater than 93% of total enzyme activity, and this isoform was purified over 200-fold.

An updated view on the long‐term survival and significance of marine protist resting stages

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Resting stages of protists act as biological time capsules when buried in marine sediments, preserving viable cells that enable the study of ecological and evolutionary processes across timescales. Recent studies have extended the known viability in diatoms to several millennia and in dinoflagellates to over a century, while also identifying ...

Nutritional Content of Artemia sp. Fed with Chaetoceros calcitrans and Skeletonema costatum

open access: yesHayati Journal of Biosciences, 2014
Artemia sp. is a natural food with high protein content, especially amino acid. Nowadays, Indonesia still relies on import for its supply. Hence, the utilization of local Artemia sp. as an alternative to the imported product is recommended as it contains

Warming enhances protozooplankton top‐down control and nutrient competition

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Protozooplankton regulate microbial food webs through top‐down control and nutrient cycling, yet their grazing impacts under ocean warming, particularly in subsurface chlorophyll maximum (SCM) layers, remain poorly understood. This study investigated spatial and seasonal variability in protozooplankton grazing in the northern East China Sea ...

Surface slicks structure microbial and viral neuston in relation to biogeochemical conditions

open access: yesLimnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract The sea‐surface microlayer (hereafter microlayer), which forms the interface between the ocean and atmosphere, plays a key role in nutrient cycling and microbial dynamics. Coastal slicks, which are viscous and biogenic surface films, often serve as hotspots for microbial activity, yet their structure and interactions remain incompletely ...
