TLDR
An attempt is made to borrow information from the physiology of bacteria, fungi, and higher plants where they augment observations on algae in an attempt to find new insights into the metabolic roles of nutrients and the mechanisms of their assimilation.Abstract:
Treatments of inorganic nutrition tend to become listings of poorly related facts and observations. As more information becomes available, this should give way to a drawing together of observations in an attempt to find new insights into the metabolic roles of nutrients and the mechanisms of their assimilation. In the present review, an attempt is made to do this, borrowing information from the physiology of bacteria, fungi, and higher plants where they augment observations on algae. In doing so, some erroneous suggestions are probable, but hopefully areas of needed research will be pointed out.read more

Nutrient limitation of phytoplankton in freshwater and marine environments: A review of recent evidence on the effects of enrichment1
R. E. Hecky,Peter Kilham +1 more
TL;DR: It is concluded that the extent and severity of N limitation in the marine environment remain an open question, despite the fact that by the late seventies the evidence for P limitation had become so great that phosphorus control was recommended as the legislated basis for controlling eutrophication in North American and European inland waters.

Ammonium and nitrate nutrition of plants
R. J. Haynes,K. M. Goh +1 more
TL;DR: In this article, the effects of ammonium plus nitrate as a nitrogen source were investigated and they showed that ammonium toxicity is associated with changes in metabolic changes characteristic of toxicity.

The utilization of inorganic and organic phosphorous compounds as nutrients by eukaryotic microalgae: a multidisciplinary perspective: part 1
TL;DR: This comprehensive literature review of the phosphorus nutrition and metabolism of eukaryotic microalgae deals sequentially with extracellular P-compounds available for algal utilization and growth and includes specific macroalgae in considering certain subtopics where such algae were better investigated and provided a good basis for comparison.

Nitrogen Limitation in a Sonoran Desert Stream
Nancy B. Grimm,Stuart G. Fisher +1 more
TL;DR: Temporal patterns of chlorophyll a accrual suggest that availability of nitrogen limited the rate of algal increase, but not the ultimate periphyton standing crop, so it is proposed that nitrogen limitation is common in the desert Southwest.

Lipid composition of the nitrogen starved green alga Neochloris oleoabundans
TL;DR: Neochloris oleoabundans has been cultivated in mineral medium deficient in nitrogen and the yield of lipids was 35–54% of cell dry weight.

Temperature and phytoplankton growth in the sea
TL;DR: The variation in growth rate with temperature of unicellular algae suggests that an equation can be written to describe the maximum expected growth rate for temperatures less than 40°C, a logical starting point for modeling phytoplankton growth and photosynthesis in the sea.

Half‐saturation constants for uptake of nitrate and ammonium by marine phytoplankton1
TL;DR: In this article, the half-saturation constant (Ks) was computed as a measure of the ability of a species to use low levels of nitrate and ammonium, and the success of Gonyaulax polyedra, often the dominant dinoflagellate in local red water blooms, appears to be due to its vertical migration from the sea surface in daylight to nitrate-rich water at 10-15m depth at night.
In situ studies on n2 fixation using the acetylene
TL;DR: Data obtained in experiments designed to test the feasibility of employing a simple method for measuring acetylene reduction as an index of N2 fixation in the field illustrate that the method is practical and extremely sensitive.
