A Study of Phytoplankton Dynamics in Lake Fayetteville as a Means of Assessing Water Quality [PDF]
, 1971 Phytoplankton community was analyzed for seasonal and vertical distribution in Lake Fayetteville. This northwest Arkansas reservoir maintains a stable water level and chemical input with a relatively constant, slow overflow.

Types and Distribution of Bioactive Polyunsaturated Aldehydes in a Gradient from Mesotrophic to OligotrophicWaters in the Alborán Sea (Western Mediterranean) [PDF]
, 2020 Polyunsaturated aldehydes (PUAs) are bioactive molecules suggested as chemical defenses and infochemicals. In marine coastal habitats, diatoms reach high PUA production levels during bloom episodes.

Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior
Advanced Physics Research, EarlyView.Diel vertical migration hides an unexpected twist: Phytoplankton quietly engineer their local pH landscape, splitting into behaviorally distinct sub‐groups which stay separated even in identical conditions. Circadian pH changes, occuring over the course of a day, reshape their gravitactic behavior and physiological functions in ways scientists have ...

Phytoplankton community of fouling on artificial structures in Makchachkala seaport conditions
Юг России: экология, развитие, 2015 The contents structure and dynamics of phytoplankton community formation of fouling on artificial structures in the Dagestan coastal area of the Caspian sea are researched. The most intensive process of phytoplankton community formation has been noted in

Phytoplankton Hotspot Prediction With an Unsupervised Spatial Community Model
, 2017 Many interesting natural phenomena are sparsely distributed and discrete. Locating the hotspots of such sparsely distributed phenomena is often difficult because their density gradient is likely to be very noisy.

Tolerance of polar phytoplankton communities to metals
Environmental Pollution, 2014 Large amounts of pollutants reach polar regions, particularly the Arctic, impacting their communities. In this study we analyzed the toxic levels of Hg, Cd and Pb to natural phytoplankton communities of the Arctic and Southern Oceans, and compared their sensitivities with those observed on phytoplankton natural communities from temperate areas. Mercury
