Resumen del producto

Although sequences have been obtained for several copepod species worldwide, in Mexico is starting to associate morphology to genetics using CO1. In order to relate the Linnaean taxonomy with genetic sequence of pontellid copepods from the Gulf of California, we show preliminary results. So far, have been identified morphologically 4 genera and 10 species, of which Calanopia elliptica, Calanopia minor, Pontellopsis armata and Pontellopsis brevis are new records for the study area. We have obtained genetic sequences of Calanopia elliptica, Pontellopsis armata, Labidocera acuta, Labidocera acutifrons, Pontellina plumata and Labidocera johnsoni. Preliminary analysis shows that the two-parameter model of Kimura, or K2P, to species had maximum divergence of 1.39%, a low of 0% and averaged 0.14%, while the genus level was the maximum divergence 24.02%, with a low of 21.28% and 22.44% average. Bootstrap values ??on nodes that group the species are high (95.7% to 100%) which indicates consistency. The greatest differences were observed in Pontellina plumata and lowest in Labidocera johnsoni and Calanopia elliptica, where the last two species had 0%, confirming the identity of individuals of these species. So far, the usefulness of this molecular tool can be linked successfully with morphology of pontellid copepods.
