Long-Term Trends in Calcifying Plankton and pH in the North Sea [PDF]

, 2013
Relationships between six calcifying plankton groups and pH are explored in a highly biologically productive and data-rich area of the central North Sea using time-series datasets.

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

Aquaculture 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

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)

Journal 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 ...

Transcriptomic Responses of Adult Versus Juvenile Atlantids to Ocean Acidification

Frontiers 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

Life, 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

Biological activity in the wake of an island close to a coastal upwelling [PDF]

, 2008
Hydrodynamic forcing plays an important role in shaping the dynamics of marine organisms, in particular of plankton. In this work we study the planktonic biological activity in the wake of an island which is close to an upwelling region.

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

Journal 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]

, 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 ...

Automatic plankton quantification using deep features [PDF]

, 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 ...

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

Ecologies, 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.
