Data from: A century-long genetic record reveals that protist effective population sizes are comparable to those of macroscopic species

Phillip C. Watts, Nina Lundholm, Sofia Ribeiro & Marianne Ellegaard
Effective population size (Ne) determines the rate of genetic drift and the relative influence of selection over random genetic changes. While free-living protist populations characteristically consist of huge numbers of cells (N), the absence of any estimates of contemporary Ne raises the question whether protist effective population sizes are comparably large. Using microsatellite genotype data of strains derived from revived cysts of the marine dinoflagellate Pentapharsodinum dalei from sections of a sediment record that spanned...
