Data from: Ecological and phylogenetic dimensions of the cranial shape diversification in South American caviomorph rodents (Rodentia: Hystricomorpha)

Alicia Álvarez, S. Ivan Perez & Diego H. Verzi
Caviomorph rodents represent an excellent model to explore morphological diversification on a macroevolutionary scale, as they are ecologically and morphologically diverse. We analysed cranial shape variation using geometric morphometrics and phylogenetic comparative methods. Most variation involved the shape of the rostrum, basicranium, and cranial vault, and clearly matched the phylogenetic structure. At the same time, a strong allometric pattern was associated with the length of the rostrum and cranial vault, size of the auditory bulla,...

Data from: Phylogenetic studies in Smallanthus (Millerieae, Asteraceae): a contribution from morphology

Maira Soledad Vitali & Jessica Noelia Viera Barreto
We present a cladistic analysis of all the species of Smallanthus. Six taxa within Rumfordia, Ichthyothere, Acanthospermum and Tridax served as outgroups. We evaluated the monophyly and the relationships between the species of Smallanthus through a maximum parsimony study based on morphological data. The matrix included 31 qualitative characters from floral and vegetative parts of the specimens. We also explored the phylogenetic significance of treating quantitative characters as continuous. Only one most parsimonious tree was...
