Functional-cranial approach to the influence of economic strategy on skull morphology
(Wiley-liss, Div John Wiley & Sons Inc, 2005-12)
Environmental factors are assumed to play an important role in the shaping of craniofacial morphology. Here we propose a statistical approach which can be of utility in estimating the magnitude and localization of a ...
Sciuromorphy outside rodents reveals an ecomorphological convergence between squirrels and extinct South American ungulates
(Nature Publishing Group, 2019-06)
Notoungulates were a diverse group of South American ungulates that included the rodent-like typotherians. However, they are typically compared with other ungulates and interpreted as grazers. Here we present the first ...

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 ...

An Ecomorphological Approach to Craniomandibular Integration in Neotropical Deer
(Springer, 2021-03)
South American cervids have a relatively recent evolutionary history in the Neotropics. Present taxonomical richness includes six genera and 17 species grouped in at least two clades, Blastocerina and Odocoileina. With few ...
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 ...
Complex pattern of variation in neurocranial ontogeny revealed by CT-scanning
(E Schweizerbartsche Verlags, 2018-01)
The neurocranium of hominid species has been largely studied with reference to the midsagittal plane, with variations being attributed to brain evolution. By contrast, there is limited information on variation in non-midsagittal ...
Effect of undernutrition on cranial components and somatotroph-lactotroph pituitary populations in the squirrel monkey (Saimiri sciureus boliviensis)
(Karger, 2001-04)
The aim of the present study was to investigate in monkeys the effects of undernutrition on neurocranial and facial components, correlated with a histometric and ultrastructural analysis of somatotroph (growth hormone, GH) ...
Functional morphology and fiber types of the masseter muscles of two caviomorph rodents with contrasting lifestyles, Ctenomys talarum (Ctenomyidae) and Cavia aperea (Caviidae)
(Wiley, 2021-04)
The aim of this work is the analysis of histochemical and morphometric properties of the masseter muscles of Ctenomys talarum and Cavia aperea. The former belongs to a subterranean rodent clade, Ctenomyidae, which has ...
