comment Estimating cline width at multiple points along a trait gradient
Yes, I have a grid approximating the allele frequency cline generated using ordinary kriging from 134 sites across Fennoscandinavia.

comment Estimating cline width at multiple points along a trait gradient
The allele cline is a continuous surface and you are absolutely correct that measuring the widths between curves would be ideal. I had searched the literature and could not find a way to do just what you described, so I thought my alternative method would be the best way to demonstrate the heterogeneity of the cline surface. In hybrid zone theory it is traditional to calculate the wdith of the cline as the distance between to 0.22 and 0.78 frequencies. Yes, I mean a straight unbroken line (i.e. no bend at the point).
