Our new paper in Molecular Ecology makes use of 21 introductions of wall lizards into England to show how founder history affects the loss of genetic diversity. We also show that early embryonic mortality is very high in non-native populations compared to native ones.
This looks very much like inbreeding depression, but not all populations or individuals that are inbred do poorly. So there’s different interesting things going on and it could be an interesting system to study in more genomic detail.
