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.

Probability (P-value) curves for reproductive strategy factor in PGLS models from Table 1 with varying degrees of freedom. 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.
