Large caviomorph rodent footprints of the Late Oligocene Vinchina Formation, Argentina
(Coquina Press, 2011-07)
Footprints and trackways provide valuable information about trackmaker behaviour, locomotion, spatial and temporal distribution, among others. Here we describe tetradactyl mammalian footprints and trackways recorded in ...
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 ...
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 ...
Late middle Miocene caviomorph rodents from Tarapoto, Peruvian Amazonia
(Public Library of Science, 2021)
Miocene deposits of South America have yielded several species-rich assemblages of caviomorph rodents. They are mostly situated at high and mid- latitudes of the continent, except for the exceptional Honda Group of La ...
Eocene caviomorph rodents from Balsayacu (Peruvian Amazonia)
(Springer, 2022)
The Paleogene record of caviomorph rodents has substantially increased over the last decades, and their evolutionary history better understood by the discovery of their earliest representatives, so far recorded in several ...
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 ...
