Ag-NOR staining (a), and FISH using 28S rDNA probe (b) on the Eupsophus vertebralis group mitotic plates. The E. emiliopugini, E. vertebralis and E. emiliopugini from Puyehue locality karyotypes are shown (top, middle, and bottom, respectively). Note colocalization of AgNOR and FISH signals on pair 5 (top and middle). FISH signals on four chromosomes, two of them AgNOR stained are observed in E. emiliopugini from Puyehue (bottom, see text for details).
