Copper Toxicity In The Physiology And Early Development Of Fucus Serratus, Hanne Dalsgaard Nielsen Jan 2002

Copper Toxicity In The Physiology And Early Development Of Fucus Serratus, Hanne Dalsgaard Nielsen

School of Biological and Marine Sciences Theses

Fucus serratus was used in a series of laboratory experiments to study the effects of Cu2+ exposure on the early development of zygotes and physiological effects on adults collected from Cu2+ polluted and clean habitats. Comparative studies showed that Cu2+ tolerance in Fucus is an inherited character. Zygote development and growth of embryos and adults during Cu2+ exposure indicated that Fucus serratus from a Cu2+ polluted habitat had a higher tolerance limit than material from two clean habitats. Furthermore, there was no difference in the tolerance level of zygotes, embryos and adults from the same habitat. Chlorophyll fluorescence measurements showed …
