TLDR
Cultures of eleven unicellular algae were grown at various values of pH between 6 and 10, obtained by varying the supply of CO 2, and it was suggested that the algae may be placed in three groups according to the values of the ratio at these maxima.About:

Temperature and algal growth
John A. Raven,Richard J. Geider +1 more
TL;DR: Genotypic variation in the temperature optimum for resource-saturated growth of microalgae has been used to provide envelopes of μm (maximum specific growth rate) as a function of temperature to suggest that, at their temperature optima, the cells are close to their maximum potential growth rate, based on the known kinetic properties of their catalysts.

LIGHT AND TEMPERATURE DEPENDENCE OF THE CARBON TO CHLOROPHYLL a RATIO IN MICROALGAE AND CYANOBACTERIA: IMPLICATIONS FOR PHYSIOLOGY AND GROWTH OF PHYTOPLANKTON
TL;DR: It would appear that use of a single value of θ for phytoplankton is inappropriate for ecological studies and the available data indicate that θ is about three times larger in dinoflagellates than in other algae under comparable PFDs at 20 °C.
Journal ArticleDOI
Estimating the daily contribution of carbon from zooxanthellae to coral animal respiration1
TL;DR: An equation is derived which rigorously defines the photosynthesis: respiration ratio (P:R) for any alga: invertebrate symbiotic association arid and permits the computation of the fractional contribution of translocated algal carbon to the daily respiratory carbon requirement of the host animal.

The relationship between photosynthesis and light for natural assemblages of coastal marine phytoplankton1
Trevor Platt,Alan D. Jassby +1 more
TL;DR: It is deduced that on the average the phytoplankton were photosynthesizing at only 44% maximum capacity, and the results show that PmB could be estimated from α and temperature using an empirical multiple regression equation, independent of depth.

Nutrient‐ and light‐limited growth of Thalassiosira fluviatilis in continuous culture, with implications for phytoplankton growth in the ocean
Edward A. Laws,T. T. Bannister +1 more
TL;DR: The marine diatom Thalassiosira jluvintilis was grown in a continuous culture system at 20°C on a 12:12 L:D cycle over a series of nutrient- and light-limited dilution rates and Bannister’s theoretical model describing nutrient-saturated growth gave an excellent fit to the light- limited data.

Photosynthesis in the Ocean as a Function of Light Intensity1
TL;DR: It is shown that phytoplankton populations cannot photosynthesize sufficiently to compensate for their own respiration during periods of low solar radiation, as may occur in the winter months at temperate or northern latitudes.

On pigments, growth, and photosynthesis of phaeodactylum tricornutum(1) (2).
James E. Mann,Jack Myers +1 more
TL;DR: The analysis shows that chlorophyll a and fucoxanthin are the principal light absorbing pigments and that absorption by other carotenoids is very small.

The effect of growth environment on the physiology of algae: light intensity(1) (2).
TL;DR: Measurements were made of growth, pigmentation, photosynthesis, respiration, quinone Hill reaction, cell morphology, and structure as a function of growth light intensity for various algae.

Measurements with the carbon-14 technique of the respiration rates in natural populations of phytoplankton
E.Steemann Nielsen,V.Kr. Hansen +1 more
TL;DR: In this article, a method for measuring the rate of respiration of a phytoplankton population by means of the carbon-14 technique is described, and a curve showing the net photosynthesis as a function of light intensity is obtained.
