El calamar gigante, Dosidicus gigas (D'Orbigny, 1835) es una especie semioceánica y nerítica endémica del Pacífico Oriental, distribuida desde el norte de California E.U.A (43º N) hasta el sur de Chile (20°S), incluyendo el Golfo de California. Habita aguas desde la superficie hasta 1000 metros de profundad. Particularmente dentro del Golfo de California (México), es considerado uno de los recursos pesqueros más importantes, sin embargo el manejo de la pesquería de éste cefalópodo enfrenta varias dificultades entre las que se encuentran: un corto ciclo de vida, tasa de crecimiento desigual y falta de caracteres morfométricos y/o merísticos debido a la extrema plasticidad morfológica. Con el fin de determinar si existe estructura genética poblacional en D.... |

We investigated mtDNA genetic differentiation and the phylogenetic relationships of 11 populations of the oniscidean genus Ligidium. We studied nine populations from Greece, assigned to three nominal species (L. euboicum, L. germanicum and L. beieri), and two from central Europe (L. germanicum and L. hypnorum), applying RFLP analysis of two mtDNA segments (12S rDNA and 16S rDNA) amplified by PCR. The analysis revealed seven monomorphic and four polymorphic populations, and 17 different haplotypes, each one present in one population only. Several restriction enzymes produced population specific patterns, enabling discrimination among the different populations. The estimated net nucleotide divergence between populations ranges from 1.06 to 16.52%, while the... |

An <i>Artemia</i> population from a site recently described in Chile and located in a semi-arid and humid hydrographical zone (Torres del Paine National Park), was electrophoretically characterized and cross-bred (followed through <i>F</i><sub>3</sub>) to reference samples of <i>A. franciscana</i> (San Francisco Bay, California, USA) and <i>A. persimilis</i> (Buenos Aires, Argentina), which are the species most likely to be found in Chile. The population exhibited high levels of genetic variability as judged by the percentage of polymorphic loci (<i>P</i>=53.3), mean number of alleles per locus (<i>n</i>=2.2) and mean heterozygosity (<i>H</i>=0.176). Based on... |
