Figure 6. Correlation between estimated effective population size (N eV) and (a) genetic diversity measured as expected heterozygosity (H E) in the present, as well as (b) predicted retention of H E over 100 years. Each point in the graph represents one of the 29 populations occurring at both points in time, classified into the seven metapopulations and the three single lakes monitored. Dashed line marks 95% retention after 100 years.
