title: Data from: Dispersal is associated with morphological innovation, but not increased diversification, in Cyphostemma (Vitaceae)

description: Multiple processes - including dispersal, morphological innovation, and
 habitat change - are frequently cited as catalysts for increased
 diversification. We investigate these processes and the causal linkages
 among them in the genus Cyphostemma (Vitaceae), a clade comprising ~200
 species that is unique in the Vitaceae for its diversity of growth habits.
 We reconstruct time-calibrated evolutionary relationships among 64 species
 in the genus using five nuclear and chloroplast markers, and infer the
 group’s morphological and biogeographic history. We test for changes in
 speciation rate, and evaluate the temporal association and sequencing of
 events with respect to dispersal, habitat change, and morphological
 evolution using a Monte Carlo simulation approach. In Cyphostemma, neither
 dispersal nor morphological evolution is associated with shifts in
 speciation rate, but dispersal is associated with evolutionary shifts in
 growth form. Evolution of stem succulence, in particular, is associated
 with adaptation to local, pre-existing conditions following long-distance
 dispersal, not habitat change in situ. We suggest that the pattern of
 association between dispersal, morphological innovation, and
 diversification may depend on the particular characters under study.
 Lineages with evolutionarily labile characters, such as stem succulence,
 do not necessarily conform to the notion of niche conservatism and instead
 demonstrate remarkable morphological adaptation to local climate and
 edaphic conditions following dispersal.

Additional information concerning the locus positions in the alignment are provided by the comments in the file.Lagrange_Cyphostemma_DEC_noConstraintsThis file is a Python script that is run using Python to carry out a DEC analysis based on the data contained in the provided script. This script was generated by the online Lagrange configurator(http://www.reelab.net/lagrange/configurator/index). This script enforces no constraints on the ancestral provinces and no constraints on the paths of dispersal between provinces.Lagrange_Cyphostemma_DEC_wConstraintsThis file is a Python script that is run using Python to carry out a DEC analysis based on the data contained in the provided script.
