Tested by correlation and regression analyses on data from Norwegian fjords, species diversity and Cu showed a strong negative correlation; Pb was moderately negatively correlated and Zn weakly. The negative correlation between diversity and Cu is interpreted as a cause-effect correlation, with high copper concentrations being toxic to a number of species; among the 50 most frequently occurring species, 20 were significantly missing from more copper-polluted (Cu>200 ppm) stations.

An algal culture system is regulated as a turbidostat. The system allows automatic sampling and recording of variables such as chlorophyll, biomass, pH and temperature. In addition to following culture growth, it is possible to stabilise the culture to produce a constant predetermined concentration of algae. CEROV Sta. zool., UA 716 06230 Villefranche mer, France.
