TL;DR: Almost 75% of the variance in the relative abundances of these two species along a natural silicate—phosphate gradient in Lake Michigan is explained by the Monod model.
Abstract: The results of 76 long—term competition experiments between two species of freshwater algae (Asterionella formosa and Cyclotella meneghiniana) grown along a resource gradient agree with the predictions of two different models of resource competition Both models are based on the functional resource—utilization response of each species to limiting resources The Monod and the Variable Internal Stores model of competition made similar predictions Asterionella was observed to be competitively dominant when both species were phosphate limited; Cyclotella was dominant when both species were silicate limited; and both species stably coexisted when each species was growth—rate limited by a different resource Almost 75% of the variance in the relative abundances of these two species along a natural silicate—phosphate gradient in Lake Michigan is explained by the Monod model

TL;DR: In this article, an analysis of the variation of photosynthetic rate with depth in the water column is first discussed in relation to an experimental study of the photosynthesis of a freshwater plankton diatom, Asterionella formosa Hass.
Abstract: The ecological significance of the photosynthetic characteristics of planktonic algae has long been recognized. A simple application of these to the behaviour of natural populations is not possible, however, since the latter is normally governed by the average behaviour of cells continuously circulating within the strong vertical gradient of light intensity characteristic of natural waters. In this situation the unit of ecological significance can often be interpreted as the total population present below unit area of surface. The photosynthesis of this unit constitutes the total or integral photosynthesis in the water column concerned. Its properties are of direct ecological interest. Their relation to the photosynthetic characteristics of the algae present is discussed in this paper, and the influence of various environmental factors is considered. Here an analysis of the variation of photosynthetic rate with depth in the water column is first discussed in relation to an experimental study of the photosynthesis of a freshwater plankton diatom, Asterionella formosa Hass. A mathematical model (of which a preliminary account was given by Talling, 1955), describing the general case of integral photosynthesis in the water column, is attempted. Its application to ecological situations is illustrated by examples relating to the growth of Asterionella in Lake Windermere.
