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 ...
Incisor Enamel Microstructure of Paleogene Caviomorph Rodents from Contamana and Shapaja (Peruvian Amazonia)
(Springer, 2018-02)
We investigate the enamel microstructure of 37 isolated rodent incisors from several late middle Eocene and late Oligocene localities of Contamana (Loreto Department, Peruvian Amazonia), and from the early Oligocene TAR-01 ...
Incisor Enamel Microstructure of Hystricognathous and Anomaluroid Rodents from the Earliest Oligocene of Dakhla, Atlantic Sahara (Morocco)
(Springer, 2019-09)
Seven hystricognaths and five anomaluroids have been recently described from the earliest Oligocene of the Dakhla (DAK C2) region of Morocco, based primarily on isolated cheek teeth. Here, we analyzed the enamel microstructure ...
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 ...
An allometric analysis of sexual dimorphism in Ctenomys australis: integrating classic morphometry and functional performance in vivo
(Elsevier Gmbh, 2018-04)
The South American rodents of the genus Ctenomys (Rodentia, Hystricognathi), which use both forelimbs and incisors to dig, show strong, specialized morphological adaptations to living in the underground niche. In these ...
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 ...
Autonomic neural signals in bone: Physiological implications for mandible and dental growth
(Pergamon-Elsevier Science Ltd, 2004-06)
Signals derived from the autonomic nervous system exert potent effects on osteoclast and osteoblast function. A ubiquitous sympathetic and sensory innervation of all periosteal surfaces exists and its disruption affects ...
Parámetros bioquímicos y morfométricos vinculados a la dentición de búfalas. Relaciones con el número de incisivosBiochemical and morphometrical parameters associated with dentition in water buffaloes. Relation with the number of incisors.
(Universidad Nacional del Nordeste. Facultad de Ciencias Veterinarias, 2019-06)
La clasificación de las etapas productivas y la salud de un animal o del rodeo pueden establecerse por los cambios observables en los dientes incisivos y la determinación de los valores hematológicos. Este trabajo tuvo ...
Estimación de la edad de guanaco (Lama guanicoe) a partir de los dientes incisivos: un aporte metodológico para la construcción de perfiles de mortalidadAge estimation of guanaco (Lama guanicoe) based on incisor teeth: a methodological contribution for constructing mortality profiles
(Universidad Nacional de Córdoba. Facultad de Filosofía y Humanidades. Museo de Antropología, 2017-06)
El guanaco fue el principal recurso para los cazadores-recolectores que habitaron las regiones pampeana y patagónica de Argentina. Este ungulado jugó un rol fundamental en las esferas económica, social e ideológica de estas ...
A neotype for Homunculus patagonicus Ameghino, 1891, and a new interpretation of the taxon
(Paleoanthropology Society, 2008-12)
Homunculus patagonicus was first described by Ameghino in 1891. A few studies have since added to the literature but our understanding of the affinities of this late early Miocene species or its role in the evolutionary ...
