Allozyme and mitochondrial DNA variation in Cuban populations of the shrimp Farfantepenaeus notialis (Crustacea: Decapoda)

Population genetic structure of Brazilian shrimp species (Farfantepenaeus sp., F. brasiliensis, F. paulensis and Litopenaeus schmitti: Decapoda: Penaeidae)

“…Mean heterozygosity values observed for Brazilian species (H = 0.02-0.10) were similar to those reported in other surveys (H = 0.006-0.175) (Benzie, 2000;García-Machado et al, 2001;Espinosa et al, 2002;RamosParedes and Grijalva-Chon, 2003). The Mpi locus showed a relatively high variability among Farfantepenaeus species.…”

“…The genetic structure observed in wild populations of F. notialis (Espinosa et al, 1996;García-Machado et al, 2001), F. californiensis and of L. stylirostris (De La RosaVelez et al, 2000) as well as those described here for the Brazilian populations of F. paulensis and Farfantepenaeus sp., does not seem to reflect large biogeographical events but, rather, patterns of present day dispersal. In Cuba, for example, the genetic differences detected between populations of F. notialis collected in the Batabanó and the Ana María Gulfs, which are less than 15 km apart, could be due to localized recruitment or to temporal variation in allele frequencies (García-Machado et al, 2001). These factors could be directly or indirectly related to the presence of the Calzones Gulf (the deepest in Cuba), which might prevent the movement of larvae and adults.…”

“…Recently, a major survey of published data indicates that historical events, over large biogeographic scales, may explain the patterns observed better than present day dispersal (Benzie, 2000). The genetic structure observed in wild populations of F. notialis (Espinosa et al, 1996;García-Machado et al, 2001), F. californiensis and of L. stylirostris (De La RosaVelez et al, 2000) as well as those described here for the Brazilian populations of F. paulensis and Farfantepenaeus sp., does not seem to reflect large biogeographical events but, rather, patterns of present day dispersal. In Cuba, for example, the genetic differences detected between populations of F. notialis collected in the Batabanó and the Ana María Gulfs, which are less than 15 km apart, could be due to localized recruitment or to temporal variation in allele frequencies (García-Machado et al, 2001).…”

“…In Farfantepenaeus sp., significant differences were detected between the population from Recife and those from Fortaleza (χ 2 = 27.49; p < 0.05) and Ilhéus (χ 2 = 30.57; p < 0.01). Similar levels of population genetic structuring have also been observed for several species, e.g., Australian populations of Penaeus monodon (Benzie et al, 1992) and of Melicertus latisulcatus (Mulley and Latter, 1981); populations of M. kerathurus from the Mediterranean (Mattoccia et al, 1987); Cuban populations of F. notialis (Espinosa et al, 1996;García-Machado et al, 2001); and Californian populations of L. stylirostris (Aubert and Lightner, 1999;De La Rosa-Velez et al, 2000;RamosParedes and Grijalva-Chon, 2003) and of F. californiensis (De La Rosa-Velez et al, 2000).…”

Intra- and Inter-specific Variation of Four Acetes Species (Crustacea: Decapoda: Sergestidae) Sampled along the West Coast of Peninsular Malaysia

“…Conversely, species identification studies using the mitochondrial cytochrome c oxidase subunit I (COI) gene have shown the usefulness of its sequence analysis in examining the phylogenetic and evolutionary relationships of decapod crustaceans such as penaeid shrimps (Baldwin et al 1998), brachyuran crabs of the genus Cancer (Harrison & Crespi 1999), snapping shrimp genus Alpheus , Farfantepenaeus shrimps in Cuban waters (García-Machado et al 2001), Western Pacific squat lobsters (Machordom & Macpherson 2004), European crayfish genus Austropotamobius (Trontelj et al 2005), freshwater glass shrimp Paratya australiensis in eastern Australia (Cook et al 2006), giant tiger prawn Penaeus monodon in Thai waters (Khamnamtong et al 2009),…”
