Quaternary climatic oscillations caused changes in sea level that altered
the size, number, and degree of isolation of islands, particularly in
land-bridge archipelagoes. Elucidating the demographic effects of these
oscillations increases our understanding of the role of climate change in
shaping evolutionary processes in archipelagoes. The Puerto Rican Bank
(Puerto Rico and the Eastern Islands, which comprise Vieques, Culebra, the
Virgin Islands, and associated islets) in the eastern Caribbean Sea
periodically coalesced during glaciations and fragmented during
interglacial periods of the Quaternary. To explore population-level
consequences of sea level changes, we studied the phylogeography of the
frog Eleutherodactylus antillensis across the archipelago. We tested
hypotheses encompassing vicariance and dispersal narratives by sequencing
mtDNA (ca. 552 bp) of 285 individuals from 58 localities, and four nuDNA
introns (totaling ca. 1,633 bp) from 173 of these individuals. We found
low support for a hypothesis of divergence of the Eastern Islands
populations prior to the start of the penultimate interglacial ca. 250
kya, and higher support for a hypothesis of colonization of the Eastern
Islands from sources in eastern Puerto Rico during the penultimate and
last glacial period, when a land-bridge united the Puerto Rican Bank. The
Río Grande de Loíza Basin in eastern Puerto Rico delineates a
phylogeographic break. Haplotypes shared between the Puerto Rican Bank and
St. Croix (an island ca. 105 km southeast of this archipelago) likely
represent human-mediated introductions. Our findings illustrate how
varying degrees of connectivity and isolation influence the evolution of
tropical island organisms.
