Salinity Tolerance and the Effect of Salinity and Algal Feed on the Demographics of Cultured Harpacticoid Copepods Tisbe holothuriae and Tigriopus sp. from the Messolonghi Lagoon (W. Greece)

open access: yesJournal of Marine Science and Engineering, 2022
The locally isolated harpacticoid copepods Tigriopus sp. and Tisbe holothuriae were subjected to salinity tolerance experimentation at salinities under and above of 40 ppt, and presented high halotolerances in Tigriopus LC50 (24 h) of 1 ± 4.43 ppt and ...

Unraveling the potential of the green microalga, Monoraphidium littorale in rearing some copepods and cladocerans

open access: yesAquaculture Reports, 2023
The development of a feeding protocol of copepods and cladocerans is of paramount significance nowadays because they are considered nutritionally enriched live feeds for rearing numerous aquaculture species. Two experiments were conducted to evaluate the

Transcriptomic Responses of Adult Versus Juvenile Atlantids to Ocean Acidification

open access: yesFrontiers in Marine Science, 2022
Shelled holoplanktonic gastropods are among the most vulnerable calcifiers to ocean acidification. They inhabit the pelagic environment and build thin and transparent shells of aragonite, a metastable form of calcium carbonate.

The Effect of Colored and White Light on Growth and Phycobiliproteins, Chlorophyll and Carotenoids Content of the Marine Cyanobacteria Phormidium sp. and Cyanothece sp. in Batch Cultures

open access: yesLife, 2022
Two local marine cyanobacteria, Phormidium sp. and Cyanothece sp., were batch-cultured under 18–19.5 °C, at 40 ppt salinity, using white LED light of low (40 μmol photons/m2/s) and high (160 μmol/m2/s) intensity and, additionally, blue, green and red LED

Opening Pandora’s Box: Neglected Biochemical Potential of Permafrost-Associated Fungal Communities in a Warming Climate

open access: yesJournal of Fungi, 2023
Permafrost, a vast storage reservoir of frozen organic matter, is rapidly thawing due to climate change, releasing previously preserved carbon into the environment.

Planktonic communities and chaotic advection in dynamical models of Langmuir circulation [PDF]

open access: yes, 1998
A deterministic mechanism for the production of plankton patches within a typical medium scale oceanic structure is proposed and investigated. By direct numerical simulation of a simple model of Langmuir circulation we quantify the effects of unsteady ...

Response of the Ciliates Fabrea salina and Condylostoma sp. to Different Salinities and Microalgal Feeds

open access: yesEcologies, 2022
In the quest of finding local strains of marine ciliates that can be easily cultured under a broad range of salinity and fed with microalgae, Fabrea salina Henneguy, 1890 and Condylostoma sp. Bory de St.

The Effect of Various Salinities and Light Intensities on the Growth Performance of Five Locally Isolated Microalgae [Amphidinium carterae, Nephroselmis sp., Tetraselmis sp. (var. red pappas), Asteromonas gracilis and Dunaliella sp.] in Laboratory Batch Cultures

open access: yesJournal of Marine Science and Engineering, 2021
After a 1.5-year screening survey in the lagoons of Western Greece in order to isolate and culture sturdy species of microalgae for aquaculture or other value-added uses, as dictated primarily by satisfactory potential for their mass culture, five ...

Automatic plankton quantification using deep features [PDF]

open access: yes, 2019
The study of marine plankton data is vital to monitor the health of the world’s oceans. In recent decades, automatic plankton recognition systems have proved useful to address the vast amount of data collected by specially engineered in situ digital ...
