“…North Brazil Current (NBC) rings carry these low-salinity waters northward along the east coasts of the Lesser Antilles (Carton and Chao 1999;Murphy et al 1999;Goñ i and Johns 2001). As a result, low-salinity water extends across the Caribbean basin and increases from August-November to DecemberJanuary (Corredor et al 2004). Concurrently, Chérubin and Richardson (unpubl.…”

A bio-oceanographic filter to larval dispersal in a reef-building coral

Gene flow was shown to be limited between western and eastern Caribbean populations of the reef-building coral, Acropora palmata. However, some mixing was detected among populations near Puerto Rico. Our genetic analyses categorize A. palmata samples from the east coast of the Dominican Republic with the western Caribbean population, suggesting a filter to gene flow east of the Dominican Republic. To test the hypothesis of a present day bio-oceanographic filter occurring between Puerto Rico and the Dominican Republic (i.e., in the Mona Passage), we used a Lagrangian stochastic model (LSM) of larval dispersal, coupling coral life history characteristics with physical forcing. The model operated at two spatial scales: Caribbean-wide and focusing on the Mona Passage area. Results from the Caribbean-wide study showed no significant virtual larval exchange between the two populations. The small-scale model indicated that virtual larvae do not readily traverse the Mona Passage during the corals' reproductive season. Larvae released from Mona Island, in the center of the passage, are retained in the lee within topographically steered eddies, which act, together with the larval competency period, as a de facto filter to dispersal. Combined, our findings reveal the location of a seasonal filter to gene flow and its mechanism.

“…Indeed, a few months after the peak seasonal rain in the Amazon and Orinoco river basins, a freshwater plume extends northwestward across the eastern Caribbean Sea, starting in July-August and continuing until October-November ( Figs. 2 and 4; Muller-Karger et al, 1998;Hernandez-Guerra and Joyce, 2000;Hellweger and Gordon, 2002;Corredor et al, 2004).…”
