From Manual to Automation: A Comparative Study of Manual, Standard Dilution, and Proportional–Integral Controls for Cultivation of Rhodomonas salina in a 500 L Tubular Alga Photobioreactor

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
Efficient production of high‐quality microalgae is essential for marine aquaculture, yet large‐scale cultivation of the cryptophyte Rhodomonas salina remains labor‐intensive and technically challenging. In this study, a 500‐L tubular photobioreactor (PBR) was evaluated and compared three control strategies—manual control, a programmed standard dilution

Lake–Groundwater Biogeochemical Interactions in a River‐Delimited System: The Groundwater and Lakes Urban Observatory (GLUO)

open access: yesInternational Review of Hydrobiology, Volume 110, Issue 2, Page 135-150, December 2025.
ABSTRACT Preservation of urban aquatic ecosystems is of primary importance for human well‐being, biodiversity protection and the future of society. Lake–groundwater–river interactions within urban floodplains harbour intrinsic fragility, yet remain largely understudied.

Heatwave intensity drives eco‐physiological responses in infaunal bivalves: A mesocosm experiment

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S417-S431, December 2025.
Abstract Marine heatwaves are increasing globally in intensity and duration. To investigate the potential consequences for coastal ecosystems, the effects of short‐term heat stress must be better understood. This study examined eco‐physiological responses in two common intertidal bivalves, Cerastoderma edule and Macoma balthica, to different heatwave ...

The Plastid Genome of the Cryptomonad Teleaulax amphioxeia.

open access: yesPLoS ONE, 2015
Teleaulax amphioxeia is a photosynthetic unicellular cryptophyte alga that is distributed throughout marine habitats worldwide. This alga is an important plastid donor to the dinoflagellate Dinophysis caudata through the ciliate Mesodinium rubrum in the ...

Simulating Effects of Variable Stoichiometry and Temperature on Mixotrophy in the Harmful Dinoflagellate Karlodinium veneficum

open access: yesFrontiers in Marine Science, 2018
Results from a dynamic mathematical model are presented simulating the growth of the harmful algal bloom (HAB) mixotrophic dinoflagellate Karlodinium veneficum and its algal prey, Rhodomonas salina.

Acute and long‐term warming effects on the functional response and reproductive efficiency of marine copepods

open access: yesLimnology and Oceanography, Volume 70, Issue 12, Page 3898-3911, December 2025.
Abstract The impact of climate change stressors on marine copepods, key organisms at the base of ocean food webs, remains understudied. This study examined how warming affects their functional and numerical responses, critical life history traits linked to fitness.

High Grazing Rates on Cryptophyte Algae in Chesapeake Bay

open access: yesFrontiers in Marine Science, 2018
Cryptophyte algae are globally distributed photosynthetic flagellates found in freshwater, estuarine, and neritic ecosystems. While cryptophytes can be highly abundant and are consumed by a wide variety of protistan predators, few studies have sought to ...

The Roles of Plasticity and Selection in Rapid Phenotypic Changes at the Pacific Oyster Invasion Front in Europe

open access: yesMolecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Invasive species present significant management challenges worldwide due to their ability to rapidly adapt to novel environments. The Pacific oyster Crassostrea gigas, a globally distributed invasive species, arrived in western Sweden in 2006 but has not yet colonised the low salinity waters of the Baltic Sea, presumably because low salinities

Quantifying environmental stress-induced emissions of algal isoprene and monoterpenes using laboratory measurements [PDF]

open access: yesBiogeosciences, 2015
We report here production rates of isoprene and monoterpene compounds (α-pinene, β-pinene, camphene and d-limonene) from six phytoplankton monocultures as a function of irradiance and temperature.

Culturing the solitary ascidian Phallusia nigra in closed and open water systems for tropical environmental research

open access: yesLimnology and Oceanography: Methods, Volume 23, Issue 10, Page 700-714, October 2025.
Abstract Marine and coastal ecosystems have been undergoing dramatic shifts due to global environmental changes. The rise in seawater temperature, ocean acidification, hypoxia, eutrophication, and anthropogenic pollution severely affects marine organisms.
