Molecular data exclude current hybridization between iguanas Conolophus marthae and C. subcristatus on Wolf Volcano (Galápagos Islands)

Natural hybridization may influence population fitness and responsiveness to natural selection, in particular in oceanic island systems. In previous studies, interspecific hybridization was detected between the Galápagos iguana species Amblyrhynchus cristatus and Conolophus subcristatus. Further, possible hybridization was also suggested to occur between C. subcristatus and C. marthae at Wolf Volcano on Isabela Island. In this work, we...
