Drivers of phytoplankton blooms
Science, 2016Plankton Dynamics Despite decades of study, there is little evidence to link increases in phytoplankton growth in response to springtime warming with the dynamics of phytoplankton blooms. This lack of understanding makes it difficult to make predictions about global biogeochemical cycling in response to climate change. Hunter-Cevera et al.

Cadmium in Marine Phytoplankton
2012The distribution of cadmium in the ocean is very similar to that of major nutrients suggesting that it may be taken up by marine phytoplankton at the surface and remineralized at depth. This interpretation is supported by recent data on Cd isotope distribution showing an increase in the (112)Cd/(110)Cd ratio in Cd-depleted surface water.

Production Biology of Phytoplankton
1997Abstract : To continue to critically and creatively review knowledge about interactions between bulk marine phytoplankton and zooplankton with the hydrographic and chemical environment, as well as the feedback from the biological processes to the abiotic environment. The emphasis is on regional oceanography.

Dynamics of phytoplankton–zooplankton systems with toxin producing phytoplankton
Applied Mathematics and Computation, 2014We propose periodic systems of phytoplankton-zooplankton interactions with toxin producing phytoplankton to study the effects of TPP upon extinction and persistence of the populations. Using the concept of uniform persistence, it is proved that the two populations can coexist for certain parameter regimes.

for a continuous performance of phytoplanktonic organisms. Seasonal, diurnal, and geographical variations in temperature and the occurrence of organisms under different, even extreme, conditions indicate that life, in general, is possible in a very wide temperature range.

Most studies of Amazonian algae concentrate on phytoplankton. Taxonomy and aspects of community structure are discussed by Gronblad (1945); Forster (1969, 1974); Martins (1980); Scott et al. (1965); Uherkovich (1981); Uherkovich and Schmidt (1974); Uherkovich and Rai (1979); Thomasson (1971), and many others.

A MATHEMATICAL MODEL FOR PHYTOPLANKTON
Mathematical Models and Methods in Applied Sciences, 2002This paper introduces a model of growth and dispersion of the marine phytoplankton, focusing on the effects of the currents (3D) and vertical mixing. Our method consists of describing these effects as the product of the horizontal current, which is solved along the characteristic lines, and the coupled action of vertical current and vertical diffusion,

Cytometry of Freshwater Phytoplankton
2004Publisher Summary The goals of flow cytometry (FCM) are the determination and characterization of phytoplankton abundance, composition, and physiological features. In freshwater ecosystems used for drinking-water supply, FCM offers the capability of assessing the risk of toxic algae.

Publisher Summary This chapter discusses phytoplankton crop. The crop is the biomass of phytoplankton and can be measured in various ways, for example, as the weight of matter per unit volume or under a unit of surface throughout the length of the euphotic column.
