This chapter examines 426 loci of Amplified Fragment Length Polymorphisms (AFLP) in Israeli Spalax, across coding and noncoding regions of genomes, along a gradient of increasing aridity. It compares and contrasts AFLP diversity with previous phylogenetic and ecological conclusions, based on other protein and DNA molecular markers in 114 subterranean blind mole rats representing four species of the Spalax ehrenbergi superspecies in Israel: S. galili (2n=52), S. golani (2n=54), S. carmeli (2n=58), and S. judaei (2n=60), and indicates results hereof. The chapter concludes that AFLP diversity, spreading across coding and noncoding genomic regions, is subject to natural selection like other molecular markers and displays molecular ecological adaptive radiation caused by interacting biotic and abiotic environmental stresses.
