Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?
A geographical and biological puzzle that has perplexed scientists since the late 1800s working in southern South America: why are there so few vertebrates on the island of Tierra del Fuego compared to the adjacent Patagonia mainland, including the absence of the ubiquitous Guanaco (Lama guanicoe), wild camelid of the south? An interdisciplinary search

Mounting a specific immune response increases energy expenditure of the subterranean rodent Ctenomys talarum (tuco-tuco): Implications for intraspecific and interspecific variation in immunological traits [PDF]
It was recently hypothesised that specific induced defences, which require substantial time and resources and are mostly beneficial against repeated infections, are more likely to be favoured in 'slow-living-pace' species.

We download and evaluate the whole genome of subterranean mammals, and study the mechanisms of adaptative evolution to underground stresses of subterranean mammals through comparative genomics. Abstract Life underground has provided remarkable examples of adaptive evolution in subterranean mammals; however, genome‐wide adaptive evolution to underground

ACTIVITY PATTERNS IN A SUBTERRANEAN SOCIAL RODENT, SPALACOPUS CYANUS (OCTODONTIDAE) [PDF]
Daily patterns of activity were studied under laboratory conditions in 12 coruros, Spalacopus cyanus, subterranean social rodents originally from Chile. When able to burrow, coruros spent 90% of the total time underground, and surface activity occurred during the 1st hours of darkness. When prevented from burrowing, locomotory activity of coruro groups

Postcranial skeleton of Spalacopus cyanus (Rodentia: Octodontidae): description and functional aspects [PDF]
The genus Spalacopus includes only one species, S . cyanus , endemic to central Chile and one of the species best adapted to a subterranean lifetyle in the family Octodontidae. It is a member of the lineage consisting in Octodontomys as a sister clade containing Octodon and of a clade represented by Spalacopus and Aconaemys .
