Sexual dimorphism and ontogenetic changes of Amazonian pit vipers (Bothrops atrox)
Abstract Sexual dimorphism of body size (SSD) is widespread in snakes and has been the subject of numerous studies, but few have examined sexual shape dimorphism (SShD). The present study exploresExpand

Timing of ontogenetic changes of two cranial regions in Sotalia guianensis (Delphinidae)
Abstract Despite the fact that heterochronic processes seem to be an important process determining morphological evolution of the delphinid skull, previous workers have not found allometric scalingExpand

Evolution of morphological integration in the skull of Carnivora (Mammalia): Changes in Canidae lead to increased evolutionary potential of facial traits
Morphological integration refers to the fact that different phenotypic traits of organisms are not fully independent from each other, and tend to covary to different degrees. The covariation amongExpand

Investigating South American biogeographic history using patterns of skull shape variation on Cerdocyon thous (Mammalia: Canidae)
Patterns of geographic variation of the canid Cerdocyon thous have historically been obscured by its remarkable intraspecific morphological variability. The observed distribution is highly associatedExpand

A New Tropidurus (Tropiduridae) from the Semiarid Brazilian Caatinga: Evidence for Conflicting Signal between Mitochondrial and Nuclear Loci Affecting the Phylogenetic Reconstruction of South
ABSTRACT Tropidurus Wied, 1825, is one of the most ubiquitous lizard genera distributed in open habitats of tropical and subtropical South America. Nevertheless, the broad representation of specimensExpand

High evolutionary constraints limited adaptive responses to past climate changes in toad skulls
Interactions among traits that build a complex structure may be represented as genetic covariation and correlation. Genetic correlations may act as constraints, deflecting the evolutionary responseExpand

Origin and hidden diversity within the poorly known Galápagos snake radiation (Serpentes: Dipsadidae)
Galápagos snakes are among the least studied terrestrial vertebrates of the Archipelago. Here, we provide a phylogenetic analysis and a time calibrated tree for the group, based on a sampling of theExpand

Redescription and Morphological Variation of Oxyrhopus clathratus Duméril, Bibron and Duméril, 1854 (Serpentes: Dipsadidae: Xenodontinae)
ABSTRACT. The snake Oxyrhopus clathratus, which has a restricted distribution within the Atlantic Forest Domain, exhibits great variability in color pattern, shape of the hemipenis, and scalation.Expand
