Photoacclimation of cryptophytes and diatoms to light variability in the Western Antarctic Peninsula. [PDF]

J Phycol
Abstract Meltwater stratification during austral summer along the rapidly warming Western Antarctic Peninsula (WAP) exposes coastal phytoplankton to sudden light shifts. Such variability is thought to modulate phytoplankton dynamics, yet the photoacclimation capacity of Antarctic phytoplankton, especially cryptophytes, remains unclear.

<i>Tetraselmis chuii</i> Supplementation Increases Skeletal Muscle Nuclear Factor Erythroid 2-Related Factor 2 and Antioxidant Enzyme Gene Expression, and Peak Oxygen Uptake in Healthy Adults: A Randomised Crossover Trial. [PDF]

Antioxidants (Basel)
Superoxide dismutase-rich Tetraselmis chuii (T. chuii) is derived from marine microalgae and has been reported to increase gene expression of nuclear factor erythroid 2-related factor 2 (NRF2) and related antioxidant enzymes in myoblast tissue culture ...

Spatiotemporal variability of dissolved inorganic macronutrients along the northern Antarctic Peninsula (1996–2019)

Limnology and Oceanography, Volume 68, Issue 10, Page 2305-2326, October 2023., 2023
Abstract The northern Antarctic Peninsula is a key region of the Southern Ocean due to its complex ocean dynamics, distinct water mass sources, and the climate‐driven changes taking place in the region. Despite the importance of macronutrients in supporting strong biological carbon uptake and storage, little is known about their spatiotemporal ...

Ocean acidification affects pigment concentration and photoprotection of marine phytoplankton

Limnology and Oceanography, Volume 68, Issue 4, Page 831-844, April 2023., 2023
Abstract Ocean acidification produces significant changes on phytoplankton physiology that can affect their growth and primary production. Among them, a downregulation of the enzymatic activity and the production of different cellular metabolites, including chlorophyll a (Chl a), has been observed in high CO2 cultures under stable conditions.

Modelling ecological communities when composition is manipulated experimentally

Methods in Ecology and Evolution, Volume 14, Issue 2, Page 696-707, February 2023., 2023
Abstract In an experimental setting, the composition of ecological communities can be manipulated directly. Starting from a pool of n species, it is possible to co‐culture species in different combinations, ranging from monocultures, to pairs, and all the way up to the full species pool.

Fisheries management influences phytoplankton biomass of Amazonian floodplain lakes

Journal of Applied Ecology, Volume 58, Issue 4, Page 731-743, April 2021., 2021
Tropical freshwaters fisheries typically assume that fish biomass is controlled by bottom‐up mechanisms, so that overexploitation of large predators would not affect overall ecosystem productivity. Our results, however, show that top‐down forces are important drivers of primary productivity in tropical lakes, above and beyond the effects of bottom‐up ...
