Ecological conditions and isotopic diet (13C and 15N) of Holocene caviomorph rodents in Northern Patagonia
(Academic Press Ltd - Elsevier Science Ltd, 2016-04)
This work improves our knowledge about the relationship between diet and environment among Northern Patagonian caviomorph rodents. In order to characterize long-term individual diets, we present δ13C and δ15N data from ...
Late middle Eocene Caviomorph Rodents from Contamana, Peruvian Amazonia
(Coquina Press, 2017-04)
Caviomorph rodents represent one of the most successful groups of placental mammals from South America. Despite their modern, Neogene and late Paleogene high diversity, their early evolutionary history has long remained ...
Two- versus three-dimensional morphometric approaches in macroevolution: insight from the mandible of caviomorph rodents
(Springer, 2013-03)
Morphological variation is one of the most studied dimensions of evolutionary biology, given its close relationship with the ecological aspects of biological diversification. In this work we examine the differences between ...
The role of evolutionary integration in the morphological evolution of the skull of caviomorph rodents (Rodentia: Hystricomorpha)
(Springer, 2015-05)
The mammalian cranium is a complex structure composed by three partially independent modules: face, cranial base and cranial vault. At the same time, it interacts with the mandible by sharing the masticatory function. Since ...
Early evolutionary differentiation of morphological variation in the mandible of South American caviomorph rodents (Rodentia, Caviomorpha)
(Wiley Blackwell Publishing, Inc, 2011-12)
Caviomorphs are a clade of South American rodents recorded at least since the early Oligocene (>31.5Ma) that exhibit ample eco-morphological variation. It has been proposed that phylogenetic structure is more important ...
Macrophysiological Patterns in the Energetics of Caviomorph Rodents: Implications in a Changing World
(Sociedad Argentina para el Estudio de los Mamíferos, 2015)
. In this article we review literature-based data on energy metabolism of caviomorph species in a changing world. The pioneer work of Arends and McNab (2001) analyzed the energetics of 30 caviomorph species, specifically ...
Biostratigraphy and correlation of the Monte Hermoso Formation (early Pliocene, Argentina): The evidence from caviomorph rodents
(Pergamon-Elsevier Science Ltd, 2012-04)
The Monte Hermoso Formation (Farola Monte Hermoso, Buenos Aires Province, early Pliocene) is very important because it is the type locality of biostratigraphic units of the South American mammal bearing Pliocene. These ...
