Sequence length, nucleotide composition, number of isolates per country, and % divergence between and within countries of ITS sequences for each of the 6 aquatic hyphomycete species.

Results are based on pairwise comparisons. Standard error estimate(s) were obtained by bootstrap (1000 replicates). Analyses were conducted using the Kimura 2-parameter method in MEGA4. All positions containing alignment gaps and missing data were eliminated in pairwise sequence comparisons (pairwise deletion option).
