Chromosomal variability in tuco-tucos (Ctenomys, rodentia) from the argentinean northeastern wetlands

Chromosomal diversity is a key feature for understanding the evolution of mammalian species. Rodents, the most diverse taxon among mammals, exhibit a wide chromosomal diversity; the study of their karyomorphs has contributed greatly to understand the evolution in this group. South American subterran...
