Thanks

Another possibility are NCBI's databases where sequences of microsatellies (and of course many other data) are collected: http://www.ncbi.nlm.nih.gov/nuccore/?term=microsatellite

Many journals have such information in the "supporting information" for a paper (but not always available, bec not an obligatory information).

And Molecular Ecology resources has also a database similar to heredity: http://tomato.bio.trinity.edu/

You can find microsatellite data on the following R packages :

package ade4 :

data ggtortoises (turtles)

data microsatt (cattle)

data apis108 (honey bees)

Package adegenet

nancycats (cats)

You'll find in the corresponding help files the reference papers. You will also find in these help files examples of useful multivariate methods for analyzing this kind of data

You can visit NCBI website or other banks of genes like EMBL or BOLD to find the microsatellite sequences. I think that NCBI is the best choice for this.
