Table 2.
Gene and clonal diversity among phytoplankton taxa. Gene diversity is reported as expected heterozygosity (He) and clonal diversity as the ratio of the number of unique genotypes (G) to the total number of isolates examined (N). In cases where only one population was analysed, the average He and standard deviation over all loci are listed
