The social tuco-tuco (Ctenomys sociabilis) is a species of rodent in the family Ctenomyidae. [2] It is endemic to Argentina. Its natural habitat is subtropical or tropical dry lowland grassland.

Contents

Range

The social tuco-tuco is found in the mesic meadows at about 1000 m in elevation. Its range is rather small at about 700 km2, bound by the Rio Limay to the east, the Rio Traful to the north, and the Lago Nahuel Huapi to the south. [3]

Behavior

One of the unique characteristics of this species is its social behavior. This is evidenced by observed adult burrow sharing, female tendency to stay near her birthplace, and alloparental care. With this high degree of sociability, however, there seems to be much less genetic diversity. [3]

Budin's tuco-tuco was formerly considered a species of rodent in the family Ctenomyidae. It is endemic to southeast Jujuy Province in northwest Argentina. Given the extensive human presence in its limited range, it has been suspected to be threatened. The IUCN currently views it as a subspecies of C. frater. It was named after Emilio Budin, an Argentine specimen collector who worked with Oldfield Thomas.
