Geographical, environmental, and genetic characteristics of 14 <i>L. stagnalis</i> populations involved in F_ST-Q_ST comparisons.

n indicates sample size, N mean number of alleles, AR allelic richness, HE expected heterozygosity, FIS inbreeding coefficient, and Ne effective population size. Values significantly different from zero are indicated with an asterisk. GC holds for Genetic cluster and H for Habitat. Environmental pressure is described qualitatively under three alternative factors (PP: Pesticide pressure, OAP: Other Anthropogenic pressure, GEP: Global Environmental Pressure), the levels of which are defined as a function of land use within a radius of 100 m around sample sites (see text for details).
