Data from: Carbon assimilation and habitat segregation in resurrection plants: a comparison between desiccation- and non-desiccation-tolerant species of Neotropical Velloziaceae (Pandanales)

Desiccation tolerance is the ability that some organisms show to equilibrate their water content with that of dry air and recover when water supplies are re-established. This is a widespread although rare strategy in angiosperms, and most desiccation-tolerant (DT) species are restricted to tropical rock outcrops. Such restricted ecological range is attributed to weak competitive potential caused by low productivity, due to the temporal limitation in carbon assimilation that occurs when plants desiccate. However, few...

Data from: Rate of evolutionary change in cranial morphology of the marsupial genus Monodelphis is constrained by the availability of additive genetic variation

Arthur Porto, Harley Sebastião, Silvia Eliza Pavan, John L. VandeBerg, Gabriel Marroig & James M. Cheverud
We tested the hypothesis that the rate of marsupial cranial evolution is dependent on the distribution of genetic variation in multivariate space. To do so, we carried out a genetic analysis of cranial morphological variation in laboratory strains of Monodelphis domestica and used estimates of genetic covariation to analyze the morphological diversification of the Monodelphis brevicaudata species group. We found that within-species genetic variation is concentrated in only a few axes of the morphospace and...
