Despite differences in the assumed ecological context in competing evolutionary scenarios
for early primate locomotion, there appears to be consensus about the adaptive significance …

New phylogenomic analyses of South American arboreal echimyids show that there are
three species within the genus Toromys (T. grandis, T. rhipidurus, and T. sp. nov.) and that …

Echimyidae is one of the most speciose and ecologically diverse rodent families in the
world, occupying a wide range of habitats in the Neotropics. However, a resolved phylogeny …

The Andean mountains stand out for their striking species richness and endemicity that
characterize many emblematic Neotropical clades distributed in or around these mountains …

Background Much debate has focused on how transitions in life history have influenced the
proliferation of some clades. Rodents of the subfamily Sigmodontinae (family Cricetidae) …

Biological dispersal is increasingly seen as a primary driver of speciation across the tropical
Andes. Similarly, growing evidence suggests that the Northern Andes cordilleras formed as …

Brain morphological variation is analysed through virtual endocasts in a highly diversified
clade of caviomorph rodents belonging to the family Echimyidae. Diversification in brain size …

Because of their extraordinary flower and leaf morphology, passion flowers (Passifloraceae)
have fascinated naturalists since their discovery. Within the large, diverse (600 species) …

Octodontoidea is the most species-rich clade among hystricomorph rodents. Based on a
combined parsimony analysis of morphological and molecular data of extinct and extant …
