Wing morphology, foraging strategies and flight performance in six sympatric species of molossid bats (Chiroptera: Molossidae) from Argentina Open
Differences in total wing area and shape have long been emphasized in relation to flight and foraging performance in bats. Molossid have a high species richness in the northern portion of Argentina, with many of them coexisting in sympatry…

Fractal Dimension and Suture Complexity During Postnatal Ontogeny in Neotropical Deer in Relation to Sexual Dimorphism and Other Biological Features Open
In mammals, the increase in cranial suture complexity throughout postnatal ontogeny has been linked to mechanical forces that load on the skull, including compression forces from mastication and the presence and use of cranial appendages i…

Body mass estimations in extinct caviomorphs (Ctenohystrica, Hystricognathi) from cheek tooth measures: importance of predictor, reference sample and method Open
Caviomorph rodents present an astonishing variation in sizes both nowadays and in the past. The objective of this work was to estimate the body mass of 32 extinct caviomorphs. Moreover, we seek to analyse the influence on the estimations o…

A three-dimensional geometric morphometric analysis of the morphological transformation of <i>Caiman</i> lower jaw during post-hatching ontogeny Open
Shape ontogenetic changes of the lower jaw in crocodylians are poorly understood. In order to answer some questions related to the inter- and intraspecific morphological variation of the mandible of two extant Caiman species, we performed …

Body mass estimation in Triassic cynodonts from Argentina based on limb variables Open
Body mass estimations for extinct taxa are fundamental in palaeobiological reconstructions, but little work has been done on this topic for non-mammaliaform cynodonts (NMC), the diverse and abundant Permo-Cretaceous forerunners of mammals.…
