El camarón blanco Litopenaeus schmitti ha sido explotado en el Caribe colombiano desde 1968, convirtiéndose en una especie de gran interés comercial y llevando al desarrollo de una alta actividad pesquera, que posteriormente llevó a una sobreexplotación que condujo a un decrecimiento en la captura. Debido a esta situación de la especie, con el fin de estudiar la diversidad genética y el grado de diferenciación genética dentro de cada población y entre las distintas poblaciones del camarón blanco Litopenaeus schmitti en el Caribe colombiano con ayuda de marcadores moleculares microsatélites, se capturaron 162 individuos de cuatro localidades costeras: Laguna de Navío Quebrado en La Guajira, Ciénaga Grande de Santa Marta en Magdalena, bahía de Barbacoas en... |

ABSTRACT The leopard seal (Hydrurga leptonyx) is a genetically low-studied species. In order to conduct the first genetic diversity assessment of this species in Danco Coast (Antarctic Peninsula), 423 bp of the mitochondrial DNA Control Region (mtDNA-CR) was sequenced from 13 blood samples collected in Primavera Base (62º15’S, 58º39’W) during the 2011-2012 austral summer. Our results showed high haplotype diversity (h = 0.99), with various divergent haplotypes. Our findings suggest that leopard seals in the Danco Coast could represent different phylogroups; however, including more genetic markers are needed to confirm this hypothesis. |

ABSTRACT We analysed 114 DNA samples collected in different locations within the stock G breeding grounds, including Ecuador and the northern and southern Pacific of Colombia. We genotyped 15 microsatellite loci, sexed all samples, and performed genotype comparisons. Genotype comparisons were done using a DNA register of previously genotyped individuals from the Colombian breeding ground and the Antarctic Peninsula feeding Area. We confirmed connectivity between feeding grounds in Antarctic Peninsula and breeding grounds in Colombia and Ecuador using microsatellite loci. We found recaptures within each sampling location in the same year, but we also found a few recaptures in the same locations between years both in breeding and feeding grounds.... |
