A phytoplankton–toxic phytoplankton–zooplankton model
Ecological Complexity, 2011Abstract Several field data and experiments show that zooplankton may react to the presence of toxic phytoplankton by reducing its consumption up to the point of starvation. We propose a mathematical system to model this situation using a Monod–Haldane response function.

A Model of Phytoplankton Blooms [PDF]
The American Naturalist, 2002 A simple model that describes the dynamics of nutrient-driven phytoplankton blooms is presented. Apart from complicated simulation studies, very few models reported in the literature have taken this "bottom-up" approach. Yet, as discussed and justified from a theoretical standpoint, many blooms are strongly controlled by nutrients rather than by higher

Is there a decline in marine phytoplankton? [PDF]
Nature, 2011 Phytoplankton account for approximately 50% of global primary production, form the trophic base of nearly all marine ecosystems, are fundamental in trophic energy transfer and have key roles in climate regulation, carbon sequestration and oxygen production.

Dynamics of a nutrient-phytoplankton model with random phytoplankton mortality
Journal of Theoretical Biology, 2020This study formulates a stochastic nutrient-phytoplankton model which incorporates the effect of white noise on phytoplankton growth. The global existence and uniqueness of a positive solution, stochastic boundedness, and stochastically asymptotic stability are well explored.

Zur Vervollkommnung der quantitativen Phytoplankton-Methodik
, 1958SynopsisAll the important questions in counting phytoplankton are reviewed. The methods described refer primarily to fresh water but are applicable to marine phytoplankton as well. No attempt has been made to review the whole of the voluminous literature

Ecological Research, 2008
AbstractBecause phytoplankton live at the interface between the abiotic and the biotic compartments of ecosystems, they play an important role in coupling multiple nutrient cycles. The quantitative details of how these multiple nutrient cycles intersect is determined by phytoplankton stoichiometry.

Flow cytometry and phytoplankton [PDF]
Cytometry, 1989 AbstractFlow cytometry and sorting are now an important technology in aquatic research. Simultaneous measurements of individual particle cell size, fluorescence, and light scatter properties are directly applicable to current topics in aquatic research. Flow sorting may be employed to obtain subsets of cells for analysis by conventional methods.

Annual Review of Marine Science, 2020
Photosynthesis evolved in the ocean more than 2 billion years ago and is now performed by a wide range of evolutionarily distinct organisms, including both prokaryotes and eukaryotes. Our appreciation of their abundance, distributions, and contributions to primary production in the ocean has been increasing since they were first discovered in the ...
