title: Data from: Testing for ancient adaptive radiations in Neotropical cichlid fishes

description: Most contemporary studies of adaptive radiation focus on relatively recent
 and geographically restricted clades. It is less clear whether
 diversification of ancient clades spanning entire continents is consistent
 with adaptive radiation. We used novel fossil calibrations to generate a
 chronogram of Neotropical cichlid fishes and to test whether patterns of
 lineage and morphological diversification are congruent with hypothesized
 adaptive radiations in South and Central America. We found that
 diversification in the Neotropical cichlid clade and the highly diverse
 tribe Geophagini was consistent with diversity-dependent, early bursts of
 divergence followed by decreased rates of lineage accumulation. South
 American Geophagini underwent early rapid differentiation in body shape,
 expanding into novel morphological space characterized by elongate-bodied
 predators. Divergence in head-shape attributes associated with trophic
 specialization evolved under strong adaptive constraints in all
 Neotropical cichlid clades. The South American Cichlasomatini followed
 patterns consistent with constant rates of morphological divergence.
 Although morphological diversification in South American Heroini was
 limited, Eocene invasion of Central American habitats was followed by
 convergent diversification mirroring variation observed in Geophagini.
 Diversification in Neotropical cichlids was influenced by the early
 adaptive radiation of Geophagini, which potentially limited
 differentiation in other cichlid clades.
description: BEAST XML file used for
 datingThis file contains the
 executable XML file that generates the chronogram used in the paper as
 described in the methods. Output from running this file in BEAST 1.6.2 was
 used to generate the Maximum Clade Credibility chronogram and the set of
 1000 randomly sampled posterior chronograms used in all analyses performed
 in the paper.López_Fernandez et al BEAST XML

 CichlinaeMCC chronogramThis file contains a
 Newick-formatted version of the MCC chronogram of Neotropical cichlids
 used in all lineage and phenotypic analyses. African, Indian and
 Madagascan taxa used for cichlid dating in the BEAST run have been pruned
 for analysis of Neotropical taxa. This file is directly readable in the
 relevant R packages used in the paper. This chronogram was pruned to
 generate trees for the clades Geophagini, Cichlasomatini and Heroini as
 needed for analysis presented in the paper.López-Fernández et al

 Newick-formatted trees of Neotropical cichlids obtained by randomly
 sampling the posterior distribution of trees obtained from the BEAST
 search performed using the XML file provided. African, Indian and
 Madagascan taxa used for cichlid dating in the BEAST run have been pruned
 for analysis of Neotropical taxa. This file is directly readable in the
 relevant R packages used in the paper. These chronograms were pruned to
 generate 1000-tree sets for the clades Geophagini, Cichlasomatini and
 Heroini as needed for analysis presented in the paper.López-Fernández et al

 phenotypic analyses as described in the methods. Data are presented for
 each individual specimen used, providing also the museum catalog number
 for each specimen. See text of the paper for details of transformations
