By a previously established test procedure that uses 4.5 μM phosphate in the medium, the marine red alga Champiaparvula (C. Agardh) Harvey was shown to be more sensitive to arsenite [As(III)] than to arsenate [As(V)]. Mature cystocarps (evidence of

A previously developed static-renewal toxicity test was used to test the effect of 10 organic chemicals on the growth and reproduction of the marine red alga Champia parvula (C. Agardh) Harvey. The test measured vegetative growth, formation of tetras

Pericarps generally are thought of as structures having determinate growth, serving as a protective covering for the developing gonimoblast. In laboratory culture, the pericarps of Champia parvula (C. Agardh) Harvey, Lomentaria baileyana (Harvey) Far
