Figure 1 in Reptile distribution may identify terrestrial islands for conservation: the Levant's 'Arava Valley as a model

Figure 1. Schematic map of Cisjordan, Transjordan and the 'Arava valley shared by them. The number of squamate taxa in an area is encircled in that area. The number of species shared by two areas is in the arc bridging them. In the middle of the southern complex is a bridge joining all three areas.
