Rapid Opto-electrochemical Differentiation of Marine Phytoplankton. [PDF]

ACS Meas Sci Au, 2022
The use of electro-generated oxidants in seawater facilitates the discrimination of different plankton groups via monitoring the decay in real time of their chlorophyll-a (chl-a) fluorescence signals following potentiostatic initiation of electrolysis in their vicinity (Yang M.Chem. Sci.2019, 10( (34), ), 7988-7993).

Amine Oxidases of Marine Phytoplankton [PDF]

Applied and Environmental Microbiology, 1991
Some phytoplankton utilized a novel mechanism for obtaining nitrogen from primary amines. They oxidized the primary amines to produce extracellular hydrogen peroxide and aldehydes and used the third reaction product, ammonium, as a nitrogen source. The specificity, regulation, inhibition by bromoethylamine, and potential dependence on copper of this ...

Dimensions of Marine Phytoplankton Diversity [PDF]

Biogeosciences, 2019
Abstract. Biodiversity of phytoplankton is important for ecosystem stability and marine biogeochemistry. However, the large scale patterns of diversity are not well understood, and are often poorly characterized in terms of statistical relationships with environmental factors (e.g. latitude, temperature, productivity). Here we use ecological theory and

Estimation of Phytoplankton Size Classes in the Littoral Sea of Korea Using a New Algorithm Based on Deep Learning

Journal of Marine Science and Engineering, 2022
The size of phytoplankton (a key primary producer in marine ecosystems) is known to influence the contribution of primary productivity and the upper trophic level of the food web. Therefore, it is essential to identify the dominant sizes of phytoplankton

Iron Uptake Mechanisms in Marine Phytoplankton. [PDF]

Front Microbiol, 2020
Oceanic phytoplankton species have highly efficient mechanisms of iron acquisition, as they can take up iron from environments in which it is present at subnanomolar concentrations. In eukaryotes, three main models were proposed for iron transport into the cells by first studying the kinetics of iron uptake in different algal species and then, more ...

Observing and modelling phytoplankton community structure in the North Sea [PDF]

Biogeosciences, 2017
Phytoplankton form the base of the marine food chain, and knowledge of phytoplankton community structure is fundamental when assessing marine biodiversity.

Hybrid quantum-classical convolutional neural network for phytoplankton classification

Frontiers in Marine Science, 2023
The taxonomic composition and abundance of phytoplankton have a direct impact on marine ecosystem dynamics and global environment change. Phytoplankton classification is crucial for phytoplankton analysis, but it is challenging due to their large ...

Metabolomic Insights into Marine Phytoplankton Diversity. [PDF]

Mar Drugs, 2020
The democratization of sequencing technologies fostered a leap in our knowledge of the diversity of marine phytoplanktonic microalgae, revealing many previously unknown species and lineages. The evolutionary history of the diversification of microalgae can be inferred from the analysis of their genome sequences.
