Abstract
POLDSIP 1.0 is a free software package to estimate the distribution of pollen dispersal distances from mother-offspring diploid genotypic data. It requires the spatial coordinates and genotypes of a sample of seed plants and their respective maternal progenies, providing estimates of the average, variance and kurtosis of the pollen dispersal curve. POLDSIP also estimates the effective reproductive density of pollen donors and the correlation of paternity within and among maternal sibships. POLDSIP is useful for characterizing the spatial scale of pollen dispersal, for assessing the variation in male fertility and for investigating biological factors affecting correlated paternity in plants.
