A metapopulation of the lizard Anguis fragilis (Squamata: Anguidae) on a local scale in Dorset, Great Britain, as indicated by spatial distribution and movement

A metapopulation is a group of spatially structured populations, consisting of distinct units (subpopulations) that are separated by space or barriers, and connected by dispersal movements. Evidence derived from Gaussian finite-mixture models and dispersal events suggests that slow-worms may exist i...
