Adjustments of Limnoperna fortunei (Bivalvia: Mytilidae) after ten years of invasion in the Americas

Limnoperna fortunei (Dunker, 1857) or golden mussel invaded South America through the Río de la Plata estuary in 1991. Ten years later, the golden mussel lives in the main rivers of the Plata Basin. The gonadal cycle and the population settlement in a temperate climate are discussed in this article....
