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.
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 file.xmlLópez-Fernández et al
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 Cichlinae1000 chronogramsThis file
contains 1000 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 morphometric dataThis file contains the raw values for Standard Length
and 8 morphometric variables used for 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 and analyses.López-Fernández et
al body size dataThis file contains the untransformed maximum body size
data per species used in the analyses. See text of the paper for details
of analyses.
