Copper toxicity to microscopic stages of giant kelp Macrocystis pyrifera: interpopulation comparisons and temporal variability

Abstract

Long-term reproductive endpoints were more sensitive to Cu than were short-term vegetative endpoints, with No Observed Effect Concentrations of < 10μg l-1 for sporophyte production, 10μg l-1 for sporophyte growth, 10μg l-1 for germ-tube growth, and 50μg l-1 for germination inhibition. -from Authors
