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 ...

PlanktoScope: Affordable Modular Quantitative Imaging Platform for Citizen Oceanography

open access: yesFrontiers in Marine Science, 2022
The oceans represent 97% of all water on Earth and contain microscopic, drifting life, plankton, which drives global biogeochemical cycles. A major hurdle in assessing marine plankton is the planetary scale of the oceans and the logistical and economic ...

The Plankton Lifeform Extraction Tool: a digital tool to increase the discoverability and usability of plankton time-series data [PDF]

open access: yesEarth System Science Data, 2021
Plankton form the base of the marine food web and are sensitive indicators of environmental change. Plankton time series are therefore an essential part of monitoring progress towards global biodiversity goals, such as the Convention on Biological ...

Plankton [PDF]

open access: yesCurrent Biology, 2017
Plankton comprises unicellular plants - phytoplankton - and generally small (millimetres or less) animals - zooplankton - that are adrift on the currents. Phytoplankton are responsible for about 45% of global annual primary production and are grazed by zooplankton, which in turn are suitably sized food items for predators including commercially ...

Fungal parasitism on diatoms alters formation and bio–physical properties of sinking aggregates

open access: yesCommunications Biology, 2023
Fungal parasites are found to effectively control the fate of phytoplankton-derived organic matter, potentially enhancing remineralization and reducing sedimentation in freshwater and coastal systems.

Impacts of Microplastics on the Swimming Behavior of the Copepod Temora turbinata (Dana, 1849)

open access: yesFluids, 2020
Zooplankton are prone to the ingestion of microplastics by mistaking them for prey. However, there is a lack of knowledge about the impacts of microplastic availability on zooplankton behavior.

The plankton of Richards Bay [PDF]

open access: yesHydrobiological Bulletin, 1973
A study of the plankton of the estuary system of Richards Bay in South Africa has been carried out by the plankton research group at the Port Elizabeth Museum. This study in conjunction with other ecological studies provide an environmental survey of the site of the Richards Bay Harbour now under construction. 2.

Plankton are not passive tracers: Plankton in a turbulent environment [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2006
Spectral analysis was performed on a series of oceanographic transects collected using an optical plankton counter and conductivity‐temperature‐depth probe. The “physical” time series (i.e., temperature) power spectra showed a single passive scaling relationship across the entire range of sampling scales (1–8192 s) that was expected from turbulence ...
