Influence of Lipid Composition in Amplifying or Ameliorating Toxicant Effects on Phytoplankton

Abstract

Research conducted under this grant has demonstrated that lipid content and composition of diatoms varied greatly during the growth cycle. More variation was found over a 24 hour period. A portion of the lipid content response was found to be entrained with the light/dark regime. However, the data also suggested that a portion of the lipid cycling was not entrained with the light/dark regime, but may be under control of other biological rhythms. Preliminary toxicant exposure experiments have suggested that the time of day when algae are exposed to toxicants may alter physiological responses to the toxicant. Keywords: Diurnal variations.
