title: Data from: Ecological opportunity alters the timing and shape of adaptive radiation

description: The uneven distribution of diversity is a conspicuous phenomenon across
 the tree of life. Ecological opportunity is a prominent catalyst of
 adaptive radiation and therefore may alter patterns of diversification. We
 evaluated the distribution of shifts in diversification rates across the
 cichlid phylogeny and the distribution of major clades across phylogenetic
 space. We also tested if ecological opportunity influenced these patterns.
 Colonization-associated ecological opportunity altered the tempo and mode
 of diversification during the adaptive radiation of cichlid fishes. Clades
 that arose following colonization events diversified faster than other
 clades. Speciation rate shifts were non-randomly distributed across the
 phylogeny such that they were disproportionally concentrated around nodes
 that corresponded with colonization events (i.e., of continents, river
 basins, or lakes). Young clades tend to expand faster than older clades;
 however, colonization-associated ecological opportunity accentuated this
 pattern. There was an interaction between clade age and ecological
 opportunity that explained the trajectory of clades through phylogenetic
 space over time. Our results indicate that ecological opportunities
 afforded by continental- and ecosystem-scale colonization events explain
 the dramatic speciation rate heterogeneity and phylogenetic imbalance that
 arose during the evolutionary history of cichlid fishes.

Phylogeny of cichlid fishes used in the analyses for the Burress and Tan paper. The clades referred to in the text are delimited by colour (colonization-associated clades in red, non-colonization-associated clades in blue). Bootstrap values are listed at internal nodes.FIG_S2_BAMM_sensitivity_to_priorFigure S2. Prior and posterior distributions of the number of rate shifts based on priors of 1, 5, and 10 shifts. Although the distribution of the number of shifts in the posterior is sensitive to the prior, the most probable number of shifts supported by Bayes Factors (used throughout the Burress and Tan paper) is robust to the number of shifts specified in the prior.FIG_S3_BAMM_CSS_top9Figure S3. The top-9 rate shift configurations from the 95% credible shift set from BAMM analysis. The frequency (f) of each configuration is listed above each plot. Circles depict the locations of rate shifts. Larger circles depict more probable shifts. The branches are color-coded according to their relative diversification rates. Warm colors depict relatively fast rates whereas cold colors depict relatively slow rates.FIG_S4_RTT_cladesFigure S4. Rate through time plots (mean ± 95% credible interval) for major clades discussed in the main text of the Burress and Tan paper. Color-codes correspond to those used in Figure 1 of the main text.
