Direct and indirect effects of elevated CO2 are revealed through shifts in phytoplankton, copepod development, and fatty acid accumulation.

open access: yesPLoS ONE, 2019
Change in the nutritional quality of phytoplankton is a key mechanism through which ocean acidification can affect the function of marine ecosystems.

Impact of nutritional history, prey quality, and quantity on grazing and photophysiological responses in the mixoplanktonic dinoflagellate Karenia brevis

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2603-2617, September 2025.
Abstract The mixotrophic toxic dinoflagellate Karenia brevis forms red tides almost annually along Florida's Gulf coast. We hypothesize that the nutritional status and abundance of its prey, the picocyanobacterium Synechococcus, will affect its feeding rates and growth responses, with implications for bloom dynamics.

Respiratory Physiology of European Plaice (Pleuronectes platessa) Exposed to Prymnesium parvum

open access: yesFishes, 2019
During the last century, the blooms of the toxic haptophyte Prymnesium parvum have been responsible for massive fish kills in both aquaculture and wild populations. Despite decades of research, the ichthyotoxic properties of P.

Differential effects of temperature on multiple components of fitness in a modular animal reveal how temperature affects reproductive capacity

open access: yesFunctional Ecology, Volume 39, Issue 6, Page 1510-1521, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Thermal performance curves (TPCs) are important tools for predicting the sensitivity of populations to climate change. However, the interactive ways that temperature affects multiple life‐history components lead to different fitness outcomes.

Effect of Rhodomonas salina addition to a standard hatchery diet during the early ontogeny of the scallop Pecten maximus [PDF]

open access: yesAquaculture, 2007
The main objective of this study was to identify algal diets that maximize the survival and growth and alter the biochemical content of Pecten maximus larvae with the aim of improving metamorphosis. We also evaluated the potential of the cryptophyceae Rhodomonas salina as a food source for these larvae. Two flagellates, Isochrysis aff.

The Harmful Cyanobacterium Microcystis aeruginosa Differently Affects the Growth Rate and Photosynthetic Efficiency of Several Species of Marine Phytoplankton

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 2, April 2025.
The growth rates of some marine phytoplankton commonly found in estuaries were affected by Microcystis aeruginosa. Among them, Akashiwo sanguinea, which was most impacted, experienced varying effects depending on the exposure time and concentrations of M. aeruginosa cells. Our results suggest that introduced M.

[Rhodomonas salina (Cryptophyta) pastes as feed for Brachionus plicatilis (Rotifera)].

open access: yesRevista de biologia tropical, 2012
Rotifers are an important live feed for first feeding larvae of many fish species. The use of concentrated algae cells in the mass culture of the rotifer Brachionus plicatilis (Brachionidae) has opened new horizons for research on this organism. Pastes of Rhodomonas salina (Pyrenomonadaceae) obtained either by centrifugation or flocculation with ...

Relative importance of the different negative effects of the toxic haptophyte Prymnesium parvum on Rhodomonas salina and Brachionus plicatilis [PDF]

open access: yesAquatic Microbial Ecology, 2005
The aim of this study was to determine the relative importance of the different pro- cesses/mechanisms by which the toxic haptophyte Prymnesium parvum, cultured under different nutrient conditions, affects non-toxic phytoplankton competitors and microzooplankton grazers. P. parvum was cultured under steady-state growth in different nutrient conditions:

Amphioxus (Branchiostoma lanceolatum) in the North Adriatic Sea: ecological observations and spawning behavior

open access: yesIntegrative Zoology, Volume 20, Issue 2, Page 331-343, March 2025.
The European amphioxus (Branchiostoma lanceolatum), a key model in evolutionary developmental biology, is present and locally abundant in the North Adriatic Sea, which emerged as a substantial reservoir for this species. The spawning season was observed to deviate from that previously described for this species, revealing a potential for extending the ...
