What is POLDISP?

POLDISP is a free software package to estimate contemporary POLLEN DISPERSAL from mother-offspring diploid genotypic data. It contains the necessary programs to apply the two available indirect (non-paternity-based) methods of contemporary pollen dispersal estimation: KINDIST and TWOGENER. 

POLDISP provides estimates of the following parameters:

• The average pollen dispersal distance
  
• The variance of the pollen dispersal distribution
  
• The kurtosis of the pollen dispersal distribution
  
• The correlated paternity rate within and among maternal sibships
• The effective male population density
  

What kind of data requires POLDISP?

POLDISP requires the spatial coordinates and genotypes of a sample of seed-plants and their respective maternal progenies. Genotypic information must be diploid and codominant.
