Fig. 1From: Hydrogen isotopes reveal evidence of migration of Miniopterus schreibersii in EuropeProportion of Miniopterus schreibersii predicted as being ‘local’ and ‘non-local’ at each site in autumn and spring.

The species’ distribution map as currently described by the IUCN [2] is shown in greenBack to article page
