title: Data from: Dispersal capacity predicts both population genetic structure and species richness in reef fishes

description: Dispersal is a fundamental species characteristic that should directly
 affect both rates of gene flow among spatially distributed populations and
 opportunities for speciation. Yet no single trait associated with
 dispersal has been demonstrated to affect both micro- and
 macroevolutionary patterns of diversity across a diverse biological
 assemblage. Here, we examine patterns of genetic differentiation and
 species richness in reef fishes, an assemblage of over 7,000 species
 comprising approximately one-third of the extant bony fishes and over
 one-tenth of living vertebrates. In reef fishes, dispersal occurs
 primarily during a planktonic larval stage. There are two major
 reproductive and parental investment syndromes among reef fishes, and the
 differences between them have implications for dispersal: (1) benthic
 guarding fishes lay negatively buoyant eggs, typically guarded by the male
 parent, and from these eggs hatch large, strongly swimming larvae; in
 contrast, (2) pelagic spawning fishes release small floating eggs directly
 into the water column, which drift unprotected before small weakly
 swimming larvae hatch. Using phylogenetic comparative methods, we show
 that benthic guarders have significantly greater population structure than
 pelagic spawners and additionally that taxonomic families of benthic
 guarders are more species rich than families of pelagic spawners. Our
 findings provide a compelling case for the continuity between micro- and
 macroevolutionary processes of biological diversification and underscore
 the importance of dispersal-related traits in influencing the mode and
 tempo of evolution.

As the true phylogeny is unknowable, all statistical estimates are best guesses. Because there are five clades with the benthic guarding reproductive strategy, the most conservative choice for degrees of freedom would be d.f. = 4, shown as a dotted vertical line; d.f. = 4 is certain to be an underestimate of the true degrees of freedom as benthic guarding is common among freshwater fishes suggesting many character state changes along the full acanthomorph tree. An upper bound to degrees of freedom might be set by adjusting for polytomies (following Purvis and Garland 1993; Garland and Díaz-Uriarte 1999) as shown as vertical dotted lines. Finally the phylogenetic degrees of freedom determined by GEE is shown as a solid vertical line. The true degrees of freedom for our PGLS analyses are likely to fall somewhere within this bounded range for degrees of freedom.Probabilities_supp_fig.pdfFull reference list for sources of original Fst estimatesBibliography corresponding to entries in the "Database of Fst data for benthic fishes"GeneticData_refs.rtf
