Revealing Seasonal Patterns and Metabolism of Microbial Plankton in a Productive Coastal Upwelling System

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Increasing our knowledge about the structure and metabolism of the microbial plankton community in coastal upwelling systems is essential for efficiently managing the resources of these highly productive ecosystems. Here we explore seasonal variations of this community in the NW Iberian coastal upwelling system by measuring variables informing

How nitrogen and phosphorus stoichiometry drive the physiology and photosynthesis of Scrippsiella acuminata (Dinophyceae)

open access: yesJournal of Phycology, Volume 62, Issue 1, Page 96-111, February 2026.
Abstract Development and growth of microalgae are mainly sustained by two essential nutrients: nitrogen (N) and phosphorus (P). Although single‐nutrient limitation has been extensively studied, the balance between N and P availability remains less explored.

Biochemical characterization of phosphoenolpyruvate carboxykinases from multiple species of brown algae

open access: yesJournal of Phycology, Volume 61, Issue 5, Page 1321-1338, October 2025.
Abstract Phosphoenolpyruvate carboxykinase (PEPCK) is involved in the conversion of phosphoenolpyruvate (PEP) to oxaloacetate (OAA). In addition to playing a role in gluconeogenesis in various organisms, PEPCK also functions in the C4 cycle to concentrate CO2 for photosynthesis in some C4 plants.

Inhibition of cosmopolitan toxic diatom, Pseudo‐nitzschia, by seaweeds

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2591-2602, September 2025.
Abstract Pseudo‐nitzschia is a genus of harmful algal bloom (HAB)‐forming diatoms that can produce domoic acid (DA), a compound known to cause death and disease in marine wildlife as well as amnesic shellfish poisoning in humans. Here, we show the effects of multiple cultivable seaweeds—Saccharina latissima (sugar kelp), Ulva spp., and Gracilaria spp ...

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

Effect of food composition on egg production and hatching success rate of two copepod species (Calanoides carinatus and Rhincalanus nasutus) in the Benguela upwelling system [PDF]

open access: yes, 2005
We have analysed the daily egg production (EPR) and hatching success rates of the calanoid copepods Calanoides carinatus and Rhincalanus nasutus as a function of nano- and microplankton concentration and composition in the northern Benguela upwelling ...

How marine heatwaves are reshaping phytoplankton in the Northeast Pacific

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2447-2463, September 2025.
Abstract In 2015 and 2019, the Northeast Pacific has undergone significant heatwave events that strongly disrupted marine ecosystems functioning and services. Here we use the data collected by the Continuous Plankton Recorder (CPR) survey to investigate the changes in summer phytoplankton abundance and morphology and show an increase in prolate (i.e ...
