Craniodental and forelimb specializations for digging in the South American subterranean rodent Ctenomys (Hystricomorpha, Ctenomyidae)
(Elsevier Gmbh, 2017-11)
We explored the distribution of tooth- and scratch-digging specializations in species of the subterranean rodent Ctenomys (tuco-tucos) from diverse environments and representing different clades. Principal component analysis ...
Postnatal ontogeny of limb proportions and functional indices in the subterranean rodent Ctenomys talarum (Rodentia: Ctenomyidae)
(Wiley-liss, Div John Wiley & Sons Inc, 2014-05)
Burrow construction in the subterranean Ctenomys talarum (Rodentia: Ctenomyidae) primarily occurs by scratch-digging. In this study, we compared the limbs of an ontogenetic series of C. talarum to identify variation in ...
Postnatal development of subterranean habits in tuco-tucos Ctenomys talarum (Rodentia, Caviomorpha, Ctenomyidae)
(Springer Tokyo, 2015-12)
Postnatal development of subterranean habits was investigated in Los Talas’ tuco-tuco Ctenomys talarum, a subterranean caviomorph rodent endemic from South America. Since in this species, some key morpho-functional traits ...
Carpal‐metacarpal specializations for burrowing in South American octodontoid rodents
(Wiley Blackwell Publishing, Inc, 2011-08)
Among the ecomorphologically diverse Octodontoidea rodents, fossorial habits are prevalent in Ctenomyidae and Octodontidae and occur in some members of Echimyidae. To detect traits linked to scratch‐digging, we analyzed ...
Forelimb proportions and fossorial adaptations in the scratch-digging rodent Ctenomys (Caviomorpha)
(Alliance Communications Group Division Allen Press, 2011-06)
Members of the genus Ctenomys (tuco-tuco; Rodentia: Caviomorpha: Octodontidae) are considered scratch diggers. We compared the forelimbs of adult C. azarae with those of 13 species within other genera of caviomorph rodents ...
Functional morphology and identity of the thenar pad in the subterranean genus Ctenomys (Rodentia, Caviomorpha)
(Wiley Blackwell Publishing, Inc, 2019-11)
As in many other fossorial tetrapods, the most obvious adaptations to scratch-digging in the subterranean tuco-tuco (Rodentia, Ctenomyidae, Ctenomys) are found in the hands, which among other adaptations, present the ...
Biomechanics and strategies of digging
(Springer, 2021)
In arid and semiarid ecosystems, digging and burrowing are common behaviors in many mammals looking for shelter, food, thermoregulation, etc. Many rodents, as tuco-tucos, may use both the foreclaws and incisors - according ...
