Genetic differentiation between morphotypes in the Antarctic limpet Nacella concinna as revealed by inter-simple sequence repeat markers
The results confirmed the morphological differences between intertidal and subtidal forms reported in other Antarctic localities and indicated that the two forms can be considered as genetically distinct populations maintaining low levels of gene flow. Expand
A contribution to the understanding of phylogenetic relationships among species of the genus Octopus (Octopodidae: Cephalopoda)
A Bayesian approach was used to estimate as yet unknown phylogenetic relationships among O. tehuelchus from the southwestern Atlantic, new specimens of O. mimus (Chile and Peru) and other Octopus species, and used Bayes factors to test phylogenetic hypotheses. Expand
Global genetic diversity of Aedes aegypti
This study provides a reference database of genetic diversity that can be used to determine the likely origin of new introductions that occur regularly for this invasive species Ae. Expand
Genetic structure of Aedes aegypti in the city of Córdoba (Argentina), a recently reinfested area.
Assessment of the levels of genetic variability and differentiation among populations of Ae. Expand
Contrasting genetic structure of urban and rural populations of the wild rodent Calomys musculinus (Cricetidae, Sigmodontinae)
Using nine microsatellite loci to analyze the population genetic structure of the Sigmodontine rodent Calomys musculinus in two anthropically altered habitats: an agroecosystem and a city, Rodents inhabiting urban vacant lots showed higher levels of relatedness and genetic differentiation than rodents inhabiting the agroECosystem.

Genetic relationships among populations of Aedes aegypti from Uruguay and northeastern Argentina inferred from ISSR‐PCR data
Aedes aegypti (L.) (Diptera: Culicidae), the main vector of yellow fever and dengue viruses, was eradicated from Argentina between 1955 and 1963, but reinvaded the country in 1986. In Uruguay, theExpand
Oligoryzomys flavescens (Rodentia, Muridae): gene flow among populations from central-eastern Argentina
Estimated levels of gene flow among populations of the sigmodontine rodent Oligoryzomys flavescens, in which high titers of antibodies have been detected for a Hantavirus in Argentina that produces a severe pulmonary syndrome, suggest it is a center of dispersal within the species' range. Expand
Movement distances of two species of sympatric rodents in linear habitats of Central Argentine agro-ecosystems
The main effect of sex on movement distances is consistent with the promiscuous / polygynous mating system suggested for A. azarae and C. venustus, and may have implications in the management of non-crop linear habitats in agriculture landscapes. Expand
Corn mice (Calomys musculinus) movement in linear habitats of agricultural ecosystems
Opportunistic behavior of C. musculinus allows it to use linear habitats in a similar way to the 2-dimensional natural habitats and the narrowness of suitable habitats would force the mice to extend foraging trips in narrow borders. Expand
Allozyme Variation and taxonomic Status of Calomys hummelincki (Rodentia, Sigmodontinae)
The level of genetic polymorphism was analyzed in a population sample of Calomys hummelincki from Venezuela and values are higher than those reported for most species of rodents in the northern hemisphere, but are comparable to those observed in other Sigmodontinae species from Argentina. Expand
