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.

Limnology and Oceanography, EarlyView.Abstract Chlorophyll a is commonly used as a surrogate for algal biomass in lakes and oceans even though phytoplankton can readily adjust intracellular chlorophyll concentration to changes in the environment through a cellular process termed photoacclimation.

Photosynthetic pigments in phytoplankton living in high latitudes under conditions of the polar night [PDF]
Vestnik MGTU, 2016 Pigment composition and the vertical distribution of phytoplankton chlorophyll have been studied for the first time in the Barents Sea during the period when there is no photosynthetically active radiation.

Cell death in lake phytoplankton communities
Freshwater Biology, 2006 Summary1. The fraction of living and dead phytoplankton cells in seven Florida lakes was assessed by using the cell digestion assay, a non‐staining membrane permeability test. The cell digestion assay is an effective method to analyse cell viability in complex natural phytoplankton communities. 2.

Limnology and Oceanography, EarlyView.Abstract The effect of mesoscale features on the distribution of planktonic organisms are well documented. Yet, the interaction between these spatial features and the temporal scale, which can result in sudden increases of the planktonic biomass, is less known and not described at high resolution.

Limnology and Oceanography, EarlyView.Abstract Harmful algal blooms caused by toxin‐producing species of the diatom genus Pseudo‐nitzschia have been linked to anomalously warm ocean conditions in the Northern California Current System. This study compares summertime concentrations of Pseudo‐nitzschia spp.

[Corrigendum to] Effects of small-scale turbulence on lower trophic levels under different nutrient conditions [vol 32, pg 197, 2010] [PDF]
, 2009 Small-scale turbulence affects the pelagic food web and energy flow in marine systems and the impact is related to nutrient conditions and the assemblage of organisms present.

Limnology and Oceanography, EarlyView.Abstract Little is known about diatom parasitism in marine systems. Guinardia delicatula, a biomass‐dominant diatom on the Northeast US Shelf (NES), is regularly parasitized by the protistan nanoflagellate, Cryothecomonas aestivalis in this region. While G.
