Abstract
ABSTRACT Five populations of the invasive species Limnoperna fortunei were studied using polymorphic molecular (nine allozyme loci) and morphological (11 traits) markers in order to understand the patterns of genetic and morphological variability, structure and dispersion dynamics of this species in South America. High levels of genetic variability were found in South American invasive populations, and significant deviations from the Hardy-Weinberg proportions clearly indicated that the invasion process is still under way, probably by means other than natural migration.
期刊介绍：
Malacologia publishes papers on all groups of the Mollusca. Malacologia specializes in publishing long papers and monographic treatments. Complete data are especially appreciated. Papers must be of interest to an international readership. Papers in systematics, ecology, population ecology, genetics, molecular genetics, evolution and phylogenetic treatments are especially welcomed. Also welcomed are letters to the editor involving papers published or issues of import to science of the day.
