Genetic and demographic structure in a population of Ctenomys lami (Rodentia-Ctenomyidae). [PDF]
Hereditas, 2004 The variability at eight microsatellite loci was analyzed in 88 individuals of Ctenomys lami, a species of tuco-tucos. Initially considered as three subpopulations, the estimated Fst values ranged from 0.0007 to 0.0589. Additionally, a Bayesian approach presented probabilities of 0.9933 for the existence of only one population.

Species groups and the evolutionary diversification of tuco-tucos, genusCtenomys(Rodentia: Ctenomyidae) [PDF]
Journal of Mammalogy, 2011 Abstract We present the most comprehensive study to date of species groups in Ctenomys (tuco-tucos), a species-rich genus of Neotropical rodents. To explore phylogenetic relationships among 38 species and 12 undescribed forms we sequenced the complete mitochondrial cytochrome-b genes of 34 specimens and incorporated 50 previously published sequences ...

ACTA ZOOLÓGICA MEXICANA (N.S.), 2022 Ctenomys is a genus of South American subterranean rodents that is distributed from Peru to southern Argentina and Uruguay. The present work studies the reproductive behavior (courtship and copula) of Ctenomys pearsoni (Carrasco population, Uruguay). To carry out the characterization, we used an ethogram with 19 behavioral units grouped into different ...

Homomorphic Sex Chromosomes and the Intriguing Y Chromosome of Ctenomys Rodent Species (Rodentia, Ctenomyidae) [PDF]
Cytogenetic and Genome Research, 2014 Unlike the X chromosome, the mammalian Y chromosome undergoes evolutionary decay resulting in small size. This sex chromosomal heteromorphism, observed in most species of the fossorial rodent Ctenomys, contrasts with the medium-sized, homomorphic acrocentric sex chromosomes of closely related C. maulinus and C. sp.
