Title: Patterns of covariation in the masticatory apparatus of hystricognathous rodents: implications for evolution and diversification. Running head: Patterns of covariation in the masticatory apparatus of hystricognaths Authors:
The mammalian masticatory apparatus is a highly plastic region of the skull. In this study, a quantification of shape variation, the separation of phylogeny from ecology in the genesis of shape brings new insights on the relationships between morphological changes in the cranium, mandible, and muscle architecture. Our study focuses on the Ctenohystrica, a clade that is remarkably diverse and ex...

متن کاملFunctional Morphology of the Masticatory Apparatus of Two Dicynodonts (reptilia, Therapsida)
The specialized masticatory apparatus of Permo-Triassic dicynodonts (herbivorous mammal-like reptiles) is described and its function analysed by comparison of an archaic dicynodont, the pristerodont Emydops, with the advanced dicynodont Lystrosaurus. A unique feature of the dicynodont masticatory apparatus was the fact that the jaw joint consisted of two convex articulating surfaces which permi...
متن کاملThe functional morphology of the anterior masticatory apparatus in tree-gouging marmosets (Cebidae, Primates).
Although all genera of Callitrichinae feed on tree exudates, marmosets (Callithrix and Cebuella) use specialized anterior teeth to gouge holes in trees and actively stimulate exudate flow. Behavioral studies demonstrate that marmosets use large jaw gapes but do not appear to generate large bite forces (relative to maximal ability) during gouging. Nonetheless, the anterior teeth of marmosets lik...
متن کامل4Pi-microscopy of the Golgi apparatus in live mammalian cells.
We report the applicability of 4Pi-microscopy to live mammalian cells. Controlled interference of the counterpropagating wavefronts is possible despite the slight variations in cellular refractive index. Superresolved 3D-fluorescence imaging is exemplified with the first representation of the Golgi apparatus in a live cell at approximately 100 nm resolution.
