Summary Statistics Of North American Plant Populations
收藏资源简介：
Summary statistics of North American plant populations calculated by using the microsatellites of invasive and native species from multiple studies. The packages “hierfstat” (Goudet and Jombart, 2015), “vegan” (Oksanen <em>et al.</em>, 2017) and “sp” (Pebesma and Bivand, 2005; Bivand <em>et al.</em>, 2013) were used in RStudio to calculate the averaged heterozygosity over all subpopulations (<em>H</em><sub>S</sub>), the proportion of genetic variation due to differences among populations (<em>F</em><sub>ST</sub>p), the degree of non-random mating within subpopulations (<em>F</em><sub>IS</sub>) and the correlation between geographic and genetic distance (<em>r)</em>. STRUCTURE (Pritchard <em>et al.</em>, 2000) was used to calculate the number of genetic clusters (<em>K)</em> (5 iterations, burnin length 1000, 10000 MCMC reps after burnin). STRUCTURE HARVESTER (Earl & vonHoldt, 2012) was consulted to determine Evanno’s ΔK (Evanno <em>et al.</em>, 2005).
