Molecular phylogenetics of the white-lipped peccary (Tayassu pecari) did not confirm morphological subspecies in northwestern South America

M. Ruiz-García, Pinedo-Castro, M., Luengas-Villamil, K., Vergara, C., Rodriguez, J. A., and Shostell, J. M., “Molecular phylogenetics of the white-lipped peccary (Tayassu pecari) did not confirm morphological subspecies in northwestern South America”, vol. 14, pp. 5355-5378, 2015.

We sequenced the mitochondrial DNA (mtDNA) control region of 59 peccaries (44 white-lipped peccaries, Tayassu pecari, and 15 collared peccaries, Pecari tajacu). We also genotyped 3 DNA microsatellites from 78 white-lipped peccaries representing the 4 putative morphological subspecies (i.e., spiradens, aequatoris, pecari, and albirostris) present in northwestern South America (i.e., Colombia, Ecuador, Peru, and Bolivia). Our results showed: 1) the estimated diversity of the mtDNA control region in the T.

Analysis of the genetic variability and structure of Ochlerotatus taeniorhynchus (Diptera: Culicidae) populations from the Colombian Atlantic coast on the basis of random amplified polymorphic DNA markers

F. J. Bello, Segura, N. A., and Ruiz-García, M., “Analysis of the genetic variability and structure of Ochlerotatus taeniorhynchus (Diptera: Culicidae) populations from the Colombian Atlantic coast on the basis of random amplified polymorphic DNA markers”, vol. 13, pp. 4110-4123, 2014.

Ochlerotatus taeniorhynchus (Diptera: Culicidae) is a mosquito, which is an efficient vector of the virus causing epidemic-epizootic Venezuelan equine encephalitis in Colombia. This study used 9 random amplified polymorphic DNA (RAPD) markers to analyze the mosquito's genetic variability and genetic structure of 122 specimens in 7 populations from the Colombian Atlantic coast. Assuming that all loci were in Hardy-Weinberg equilibrium, diversity statistics and analyses were performed.

Genetic variability and heterogeneity of Venezuelan equine encephalitis virus vector Ochlerotatus taeniorhynchus (Diptera: Culicidae) populations of the Colombian Atlantic coast, based on microsatellite loci

F. Bello and Becerra, V., “Genetic variability and heterogeneity of Venezuelan equine encephalitis virus vector Ochlerotatus taeniorhynchus (Diptera: Culicidae) populations of the Colombian Atlantic coast, based on microsatellite loci”, vol. 8, pp. 1179-1190, 2009.

In Colombia, the mosquito Ochlerotatus taeniorhyn­chus has been identified as an efficient vector of the epidemic-epi­zootic Venezuelan equine encephalitis virus. We evaluated the ge­netic variability and heterogeneity of this mosquito in Colombian populations using eight microsatellite DNA loci. Two hundred and ten mosquito specimens collected from seven populations of the Co­lombian Atlantic coast (San Bernardo del Viento, Coveñas, Carta­gena, Barranquilla, Ciénaga, Dibulla, and Riohacha) were analyzed.
