Deep genetic structure at a small spatial scale in the endangered land snail Xerocrassa montserratensis

Species with small geographic ranges do not tend to have a high genetic structure, but some land snail species seem to be an exception. Xerocrassa montserratensis, an endangered land snail endemic to Catalonia (northeastern Iberian Peninsula), is an excellent model to study the processes afecting th...
