Population dynamics of light-limited phytoplankton: microcosm experiments.

From: Ecology | Date: January 1, 1999| Author: Huisman, Jef | Copyright information

This paper investigates the extent to which the predictions of an elementary model for light-limited growth are matched by laboratory experiments with light-limited phytoplankton. The model and experiments link the population dynamics of phytoplankton species with changes in the light gradient caused by phytoplankton shading. The model predicts that a phytoplankton population should continue to grow until, at steady state, the light intensity at the bottom of the water column equals its cri...

Competition for light between phytoplankton species: experimental tests of mechanistic theory.
Ecology ; INTRODUCTION Light is the sole energy source for nearly all plant species, ranging from the tiny phytoplankton to giant sequoia trees. As a consequence, the availability of light has a major impact on the dynamics and structure of most aquatic and terrestrial communities. Light differs from all
Physiological state of female and light intensity affect the host-plant selection of carrot psyllid, Trioza apicalis (Hemiptera: Triozidae)
European Journal of Entomology ; Key words. Triozidae, Trioza apicalis, host-plant selection, Daucus carota, Picea abies, light intensity, light gradient, host preference, behaviour, physiological state Abstract. We have studied the effect of different light gradient regimes on host-plant selection of the carrot psyllid, Trioza
DNA microarray analysis of cyanobacterial gene expression during acclimation to high light
Plant Cell ; DNA microarrays bearing nearly all of the genes of the unicellular cyanobacterium Synechocystis sp PCC 6803 were used to examine the temporal program of gene expression during acclimation from low to high light intensity. A complete pattern is provided of gene expression during acclimation of a

EDN ; MANY PEOPLE FAVOR different light and temperature settings for different rooms depending upon their mood or whether they are working or relaxing. The circuit in Figure 1 controls the intensity of the artificial light in a room and monitors the temperature of two zones. The two main circuit blocks
