“…The latitudinal range of P. argus spans the tropical and subtropical western Atlantic Ocean from North Carolina (U.S.A.) to northeastern Brazil and throughout the West Indies, the Bahamas, and Bermuda. Some genetic differentiation has been found between Brazilian and Caribbean populations, prompting a recommendation for provisional subspecific status (Sarver et al 1998), but no genetic differentiation has been found among populations across the Greater Caribbean (Silberman et al 1994;Sarver et al 1998). These findings support the notion that P. argus constitutes a pan-Caribbean metapopulation, with local populations connected via larval dispersal.…”

We analyzed and compared 17 yr of monthly settlement indices of postlarvae of the Caribbean spiny lobster, Panulirus argus, at two locations on the Mexican Caribbean coast. Along this coast, the shelf is very narrow and the local circulation is driven by waves overtopping subtidal coral reef crests. Settlement occurred year-round, but both locations showed annual rhythmicity, average seasonal maxima during the autumn, and similar interannual variation, reflecting the influence of mesoscale oceanographic processes on settlement. Significant correlations between settlement indices and a number of interrelated physical factors indicate that sea-level variation is the main factor influencing settlement. There was further association between extreme settlement pulses and extreme weather events (tropical storms and hurricanes) during the late summer-autumn. The autumn settlement peak indicates that large hurricane waves enhance the onshore transport of postlarvae that originated during the spring spawning peak. The geographic range of potential sources of larvae that settle along this coast during the periods of March-April and September-October, 5-9 months after hatching (the estimated larval duration for P. argus), was investigated by stochastic simulations integrating passive trajectories backward in time using 6 yr of stable outputs from a well-established numerical model for the entire Atlantic Ocean. Trajectories from the model indicate that the local population of P. argus depends to a large extent on larval supply from many potential source regions across and outside the Caribbean but that some larvae follow pathways that permit selfrecruitment.

“…a single population linked by an intermixing supply of widely dispersing larvae. Support for this hypothesis is based on (1) the long PLD of Panulirus argus and complex ocean circulation in the Caribbean Sea (Lyons 1980), (2) the poor spawning stock to recruit relationship for many local populations of P. argus (Butler & Herrnkind 1997, Lipcius et al 1997, Cruz et al 2001 and (3) the various genetic techniques employed over the years that have failed to discern appreciable substructure among P. argus populations in the Caribbean Sea (Menzies & Kerrigan 1979, Silberman et al 1994, Sarver et al 1998. In contrast, management of lobster stocks in the Caribbean region has long been predicated on regulations and stock assessments that assume self-recruitment.…”

Behavior such as ontogenetic vertical migration (OVM) limits the transport of marine larvae with short pelagic larval durations (PLDs), but its effect on the supposed long-distance dispersal of larvae with long PLDs is unknown. We conducted laboratory tests of ontogenetic change in larval phototaxis and examined size-specific patterns of larval distribution in the plankton to characterize OVM in the Caribbean spiny lobster Panulirus argus during its long (6 mo) PLD. We then used a coupled biophysical model to explore the consequences of OVM and hydrodynamics on larval P. argus dispersal in the Caribbean Sea. Larvae reared in the laboratory were positively phototatic for the first 2 mo and then avoided light thereafter, similar that seen in the planktonic distribution of same-sized larvae. Simulations of larval dispersal from 13 spawning sites in the Caribbean Sea predicted that twice as many larvae would recruit to nurseries if they displayed OVM compared with passive dispersers. Larvae with OVM typically settled < 400 km from where they were spawned, while passive dispersers often settled >1000 km away. OVM also produced an asymmetrical bimodal pattern of dispersal dominated by larvae that settled near their origin (~60%), but showed a second peak of larvae that dispersed over long distances (~20%). Hydrodynamics created subregional differences in the potential for self-recruitment. Our findings suggest that (1) larval behavior constrains the dispersal of even long-lived larvae, particularly in tandem with retentive oceanographic environments, and (2) larval sources of P. argus in the Caribbean Sea cannot be estimated from passive transport and surface circulation.

“…Fished scallops in the study area of the two Flexopecten forms proteus and glaber, with epibiots on their left valves Many biologists have argued that the future of descriptive taxonomy will depend on successfully embracing new techniques. Many ideas have been proposed and much progress has been achieved by using molecular data that provide a complementary approach to discriminate species separated by subtle morphological characters (Knowlton, 1993;Avise, 1994;Chan & Chu, 1996;Sarver et al, 1998;Mathews et al, 2002;Goetze, 2003). The invertebrate mtDNA 16S rDNA gene has been relatively well studied due to availability of universal primers (Kocher et al, 1989;Palumbi, 1996) and was used to resolve taxonomic problems in the family Mytilidae (Rawson & Hilbish, 1995), Veneridae (Canapa et al, 1996) and Pectinidae (Canapa et al, 2000a;Saavedra & Pena, 2004;Pujolar et al, 2010).…”
