A novel approach to estimate non‐algal particle absorption for improved retrieval of pigment concentrations in coastal waters

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 10, October 2026.
Abstract Phytoplankton play a central role in ocean biogeochemistry and understanding their composition and variability is critical for monitoring marine ecosystem dynamics. Continuous spectrophotometric measurements (using a Seabird Sci. AC‐S) along ship tracks enable high‐resolution measurements of particle spectral absorption (apλ), and beam ...

Zeaxanthin as a Broiler Pigmenter

open access: yesPoultry Science, 1976
Abstract Zeaxanthin in a stabilized gelatin beadlet formulation was evaluated as a broiler pigmenter in 2 trials. In the first experiment, low oxycarotenoid basal broiler starter and grower rations were fed continuously for 7 weeks with zeaxanthin added to both of the rations at concentrations of 11, 22 and 33 mg./kg. Zeaxanthin was compared to three

Effects of Zeaxanthin on the Insulin Resistance and Gut Microbiota of High-Fat-Diet-Induced Obese Mice

open access: yesFoods
Obesity-induced insulin resistance (IR) can precipitate metabolic disorders such as diabetes. Zeaxanthin, a crucial member of the carotenoid family, has been found to mitigate the damage caused by obesity. However, reports on the effects of zeaxanthin on

Spatial Variability and Long‐Term Trends in Winter Phytoplankton of the Warming Eastern Mediterranean Sea

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract The Eastern Mediterranean Sea (EMS) is among the fastest‐warming ocean regions, but the impacts of this warming on phytoplankton are unclear. Here, wintertime field observations were conducted across the EMS. These observations showed that small photosynthetic eukaryotes (<20 μm) dominated phytoplankton communities, collectively accounting for

Two proteins co‐expressed with photosynthetic regulators affect photosynthetic dynamics linked to changes in thylakoid pigment content and composition

open access: yesPlant Biology, Volume 28, Issue 6, Page 1796-1812, October 2026.
Two factors identified by co‐expression analysis of photosynthetic regulators are described, which are involved in thylakoid pigment content and composition and, through their function, shape the dynamics of NPQ. Abstract Rapid fluctuations in light intensity require swift regulatory adjustments of photosynthesis. Although the major plant regulators of

Open Ocean Biogeochemical Impacts of Extreme Terrestrial Precipitation

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Extreme events reshape ocean ecosystems with significant implications for nutrient and carbon cycling. Here, we demonstrate that flooding on land can be a significant driver of biogeochemical variability in the open ocean, even in relatively dry climates.

Lutein and zeaxanthin: The possible contribution, mechanisms of action and implications of modern dietary intake for cognitive development in children. [version 1; peer review: 2 approved]

open access: yesHRB Open Research, 2019
Background: Studies suggest that lutein and zeaxanthin may be important for cognitive development in children, but a comprehensive evidence synthesis is lacking.

Carotenoids and Eye Health

open access: yesEDIS, 2017
A diet rich in colorful fruits and vegetables provides a variety of nutrients as well as phytochemicals that can promote health. Lutein and zeaxanthin are two non-provitamin A carotenoids that may be protective against AMD, the leading cause of ...

Enhancement of growth and zeaxanthin accumulation via gene expression and metabolic pathways modulation in Chromochloris zofingiensis mutant CZ-Z12

open access: yesBiotechnology for Biofuels and Bioproducts
Background Chromochloris zofingiensis is recognized as a promising resource for the production of carotenoids. However, current knowledge regarding its capacity for zeaxanthin accumulation remains limited, which restricts its potential for commercial ...
