Maturing Arc signatures monired by trace element and Hf isotope systematics in the early cretaceous Zacatecas volcanic field, Mexico por Escalona Alcázar, Felipe de Jesús, Delgado Argote, Luis Alberto, Nebel, Oliver, Velasco Tapia, Fernando, Weber, Bodo, Nuñez Peña, Ernesto Patricio

“…These terranes have been considered to be fragments of exotic, intraoceanic island arcs that approached mainland Mexico after the Early Cretaceous. Trace elements and Lu-Hf isotopic systematics for primitive arc successions of the Zacatecas Volcanic Field indicate a close relationship with parts of the northern Guerrero superterrane. …”

A new parrot taxon from the Yucatán Peninsula, Mexico—its position within genus Amazona based on morphology and molecular phylogeny por Silva, Tony, Guzmán, Antonio, Urantówka, Adam D., Mackiewicz, Paweł

“…Our phylogenies, which are so far the most comprehensive for Amazona taxa enabled us to consider the most feasible scenarios about parrot colonization of the Greater and Lesser Antilles and Central America from South America mainland. The molecular dating of these migrations and diversification rate were correlated with climatic and geological events in the last five million years, giving an interesting insight into Amazon parrot phylogeography and their evolution in general.…”

The systematics of the Mexican populations of Macrobrachium digueti (Bouvier, 1895) (Decapoda: Caridea: Palaemonidae) por García Velazco, Humberto, Maeda Martínez, Alejandro M., Obregón Barboza, Hortencia, Campos Torres, Oliva, Murugan, Gopal

“…Results of the morphological revision and molecular genetic analyses with fragments of the mitochondrial genes 16S and COI confirmed the morphological identity of M. digueti as described by Bouvier and indicate that this entity is a morphologically plastic genetic species with a disjunct distribution along the peninsula and the Pacific mainland. Our study also confirms that M. acanthochirus and M. michoacanus are junior synonyms of M. digueti. …”

Biochemical systematics and population genetic structure of Anopheles pseudpunctipennis, vector of malaria in central and South America. por Manguin, S, Roberts, Donald R., Peyton, E.L., Fernández Salas, Ildefonso, Barreto, M., Fernández, R.

“…Based on our isozyme analyses, we defined these clusters as three geographic populations of An. pseudopunctipennis. Of the two mainland populations, one extends from the southern United States south through Mexico and Guatemala, and the other extends north from southern South America through Central America to Belize. …”
