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 ...
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 ...
Biting Performance and Skull Biomechanics of a Chisel Tooth Digging Rodent (Ctenomys tuconax; Caviomorpha; Octodontoidea)
(Wiley-liss, Div John Wiley & Sons Inc, 2013-02)
Biting performance is a key factor in vertebrate groups possessing particular food habits. In subterranean rodents that use the incisors as a digging tool, apart from requirements related to gnawing abrasive diets, the ...
Cranial suture complexity in caviomorph rodents (Rodentia; Ctenohystrica)
(Wiley-liss, Div John Wiley & Sons Inc, 2017-08)
Due to their flexibility, sutures are regions that experience greater strains than the surrounding rigid cranial bones. Cranial sutures differ in their degree of interdigitation or complexity. There is evidence indicating ...
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 ...
Mandible strength and geometry in relation to bite force: a study in three caviomorph rodents
(Wiley Blackwell Publishing, Inc, 2019-02)
The monophyletic group Caviomorpha constitutes the most diverse rodent clade in terms of locomotion, ecology and diet. Caviomorph species show considerable variation in cranio-mandibular morphology that has been linked to ...
Bite it forward … bite it better? Incisor procumbency and mechanical advantage in the chisel-tooth and scratch-digger genus Ctenomys (Caviomorpha, Rodentia)
(Elsevier Gmbh, 2017-12)
The subterranean genus Ctenomys (∼60 species, ∼100–1000 g) constructs its burrows by using both forefeet and teeth throughout a wide range of habitats in South America. They show a high variation in the incisors’ angle of ...
