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...

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 subterranean rodents of the genus Ctenomys (tuco-tucos) are one of the most speciose mammalian genera. Chromosomal variability in several lineages of Ctenomys has been characterized; however, the description of the karyomorphs of the tuco-tucos that inhabit the broad area under the influence of the Iberá marsh in the northeast of Argentina (the Corrientes group) is incomplete.
