The relationship between cellular protein content and selenium accumulation in freshwater microalgae

open access: yesIntegrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Migration of Net Phytoplankton and Zooplankton in Mendum’s Pond, New Hampshire [PDF]

open access: yes, 2006
The study examines the vertical distribution and migratory behavior of net phytoplankton and zooplankton of Mendum’s Pond in Barrington, N.H. The cyanobacteria, Microcystis and Aphanocapsa were the dominant net phytoplankton in this lake.

Towards Generating Large Synthetic Phytoplankton Datasets for Efficient Monitoring of Harmful Algal Blooms [PDF]

open access: yesarXiv, 2022
Climate change is increasing the frequency and severity of harmful algal blooms (HABs), which cause significant fish deaths in aquaculture farms. This contributes to ocean pollution and greenhouse gas (GHG) emissions since dead fish are either dumped into the ocean or taken to landfills, which in turn negatively impacts the climate.

Seasonal patterns of phytoplankton photoacclimation in a dimictic oligotrophic lake over 5 yr: Implications for chlorophyll as an estimate of biomass

open access: yesLimnology 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.

Temporal evolution of plankton and particles distribution across a mesoscale front during the spring bloom

open access: yesLimnology 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.

WISER deliverable D3.1-4: guidance document on sampling, analysis and counting standards for phytoplankton in lakes [PDF]

open access: yes, 2012
Sampling, analysis and counting of phytoplankton has been undertaken in European lakes for more than 100 years (Apstein 1892, Lauterborn 1896, Lemmermann 1903, Woloszynska 1912, Nygaard 1949).

The phytoplanktonic ways of life [PDF]

open access: yesNew Phytologist, 1991
summaryThe adaptations of phytoplankton to life in suspension in water are considered with particular reference to hydromechanical factors ranging from molecular motion to ocean currents. The smallest phytoplankton, the picoplankton (0.2–2.0 μm), are the best adapted to the physico‐chemical environment of the open waters of seas and lakes and, other ...
