The Great American Schism: Divergence of Marine Organisms After the Rise of the Central American Isthmus
After a 12-million-year (My) process, the Central American Isthmus was completed 2.8 My ago. Its emergence affected current flow, salinity, temperature, and primary productivity of the Pacific andExpand

Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography.
A latitudinal gradient in biodiversity has existed since before the time of the dinosaurs, yet how and why this gradient arose remains unresolved. Here we review two major hypotheses for the originExpand

POPULATION STRUCTURE AND SPECIATION IN TROPICAL SEAS: GLOBAL PHYLOGEOGRAPHY OF THE SEA URCHIN DIADEMA
Abstract.— The causes of speciation in the sea are rarely obvious, because geographical barriers are not conspicuous and dispersal abilities or marine organisms, particularly those of species withExpand

Dispersal barriers in tropical oceans and speciation in Atlantic and eastern Pacific sea urchins of the genus Echinometra
Echinometra is a pantropical sea urchin made famous through studies of phylogeny, speciation, and genetic structure of the Indo‐West Pacific (IWP) species. We sequenced 630 bp of the cytochromeExpand

Spread of Diadema Mass Mortality Through the Caribbean
Populations of the ecologically important sea urchin Diadema antillarum suffered severe mass mortalities throughout the Caribbean. This mortality was first observed at Panama in January 1983; byExpand

Formation of the Isthmus of Panama
Independent evidence from rocks, fossils, and genes converge on a cohesive narrative of isthmus formation in the Pliocene. The formation of the Isthmus of Panama stands as one of the greatest naturalExpand

PHYLOGEOGRAPHY OF THE PANTROPICAL SEA URCHIN EUCIDARIS IN RELATION TO LAND BARRIERS AND OCEAN CURRENTS
The pantropical sea urchin genus Eucidaris contains four currently recognized species, all of them allopatric: E. metularia in the Indo‐West Pacific, E. thouarsi in the eastern Pacific, E.Expand

TEST FOR SIMULTANEOUS DIVERGENCE USING APPROXIMATE BAYESIAN COMPUTATION
Abstract Comparative phylogeographic studies often reveal disparate levels of sequence divergence between lineages spanning a common geographic barrier, leading to the conclusion that isolation wasExpand

Testing electrophoretic data for agreement with hardy-weinberg expectations
Electrophoretic data from marine organisms are routinely tested for conformity to expectations of the Hardy-Weinberg rule, but the statistical procedures used and the interpretation of their resultsExpand
