Potential overlap between suitable habitats for Astacus astacus and the two NICS. (a) Potential overlap between suitable habitats for Astacus astacus and the two NICS, Pacifastacus leniusculus and Faxonius limosus shown under current conditions. Projected changes between current and future habitat suitability for A. astacus under RCP 8.5 scenario in 2070 in relation to (b) observed heterozygosity (Ho) and (c) COI haplotypes depicted by numbers and coloured according to mitochondrial lineages (both corresponding to Fig. 1). Known species occurrences are also shown in (a,b). Maps were produced in ArcGIS 10.3 program package by authors of this study.
