The goal of this book is to provide a review of the evolutionary processes related to the genusCtenomys, addressing what has already been studied and analyzed in this genus related to areas such as Ecology, Physiology, Genetics and Cytogenetic, Ethology, Morphology, Parasitology, and Evolution. Each topic will be described in one or two chapters, written by researchers that have been working with Ctenomys species in these areas.

Preface.- The history of Ctenomys in the fossil record: a young radiation of an ancient family.- A short overview of the systematics of Ctenomys: species limits and phylogenetic relationships.- Speciation in the genus Ctenomys: an attempt to find models.- Geographical and macroecological patterns of tuco-tucos.- Phylogeography and landscape genetics in the subterranean rodents of the genus Ctenomys.- Skull shape and size diversification in the Genus Ctenomys (Rodentia: Ctenomyidae).- Biomechanics and strategies of digging.- Adaptive pelage coloration in Ctenomys.- Environmental and ecological features of the genus Ctenomys.- The diet of ctenomyids.- Ecological physiology and behavior in the genus Ctenomys.- Effects of environmental pollution on the conservation of Ctenomys.- Index.
