The results suggest some level of diet partitioning between C. flamarioni and C. minutus in the sympatric region, while the first species is more specialized on few plant items, the second showed a more varied and heterogeneous diet pattern among individuals.

Tests suggest that in environments with a lower suitability, developmental stress is increased, which is helpful in the understanding of the species evolution and in the selection of priority areas for the conservation of species.

The results provide support for the hypothesis that the allopatric distributions of ctenomyids allow them to exploit the same range of resources when available, possibly because of the absence of interspecific competition.
Effects of rodents on plant cover, soil hardness, and soil nutrient content: a case study on tuco-tucos (Ctenomys minutus)

- 16 July 2014
We analyzed the effects of tuco-tucos (Ctenomys minutus, Ctenomyidae) on plant cover, plant biomass, soil hardness, soil pH, and variables related to nutrient disposition (P, K, Mg, and Ca), using…
Wet soils affect habitat selection of a solitary subterranean rodent (Ctenomys minutus) in a Neotropical region

The results showed that habitat occupancy patterns of C. minutus are determined by soil moisture and vegetation (food supply), but there might be other habitat features that regulate the habitat choice of this mammal.

We recorded three individuals of Abrawayaomys ruschii Cunha & Cruz, 1979 in Chapeco, Santa Catarina state, expanding the known geographic distribution of the species in approximately 370 km west from…
Sharing the Space: Distribution, Habitat Segregation and Delimitation of a New Sympatric Area of Subterranean Rodents

- 9 April 2015
Investigation of the vegetation structure, plant biomass and soil hardness selected by two species of subterranean rodents when distributed in sympatry and allopatry from nine different areas along the line of coastal dunes in southern Brazil shows segregation in their selection of microhabitats.
Lineages of Tuco-Tucos (Ctenomyidae: Rodentia) from Midwest and Northern Brazil: Late Irradiations of Subterranean Rodents Towards the Amazon Forest

This study constructs phylogenies based on maximum likelihood and Bayesian inference methods with cytochrome b gene haplotypes of Ctenomys from midwest and northern Brazil and with haplotypes representative of the genus CtenOMys to place the sampled haplotypes into a phylogenetic framework and evaluates skull geometric morphometrics data among sampling sites to assess whether skull morphology corroborates the phylogenetic patterns observed.
NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics.
