“…Probably the presence of this aggressive invasive species in the same environment as C. fluminea and C. largillierti is a factor that has altered the presence of both species. This is similar to the impact produced by L. fortunei on other benthic species (Darrigran et al 1998, Darrigran and Ezcurra de Drago 2000, Darrigran 2002b, Darrigran and Damborenea 2011, Sylvester and Sardiña 2015. …”

The golden mussel, Limnoperna fortunei, is an Asian freshwater bivalve introduced in South America in the beginning of the 1990's, probably through ballast water releases in La Plata River estuary. It dispersed north through Paraná, Uruguay and Paraguay Rivers. The study evaluated the macroscale (18° to 34° S; 45° to 60° W) distribution of L. fortunei (larval stages) in the main rivers and reservoirs of La Plata Basin. Samplings were performed through 68 µm vertical plankton net hauls. Limnological variables were simultaneously determined. Larvae abundance correlated significantly with oxygen (positively) in summer, with temperature (positively) in winter and with total phosphorus and total nitrogen (both negatively) in winter. We expected densities to decrease towards north (latitudinal gradient) and increase in lentic conditions (reservoirs). Despite maximum density was found near the introduction point (La Plata River) similar value was also observed 2,000 km north (Paraguay River). The first hypothesis was refuted. The second hypothesis was partially accepted. Abundances were consistently higher in summer. Higher trophic conditions and fast flow seem to inhibit population growth. Food resources (chlorophyll a) locally influenced temporal variation. Limnoperna fortunei is widely distributed in La Plata basin, reaching high larval densities superior to 10,000 ind. m -3 , in all major sub-basins. The species exhibits a high intrinsic dispersal ability (free planktonic larvae), wide tolerance to environmental factors and dispersion is potentialized by natural dispersion processes (e.g. fauna displacement) and human facilitation (e.g. commercial navigation).Keywords: golden mussel, larval stage, Uruguay River, Paraguay River, Paraná River Duas décadas após a chegada de Limnoperna fortunei (Dunker 1857) na Bacia do PrataResumo O mexilhão dourado, Limnoperna fortunei, é um bivalve de água doce originário da Ásia e introduzido na América do Sul no início de 1990, provavelmente através da água de lastro liberada no estuário do rio La Plata. Dispersando-se para o norte através dos rios Paraná, Uruguai e Paraguai. Esse estudo avaliou a distribuição em macroescala (18° a 34° S; 45° a 60° W) de L. fortunei (estágios larvais) nos principais rios e reservatórios da bacia La Plata. Amostragens foram realizadas através de arrastos verticais com rede planctônica de 68 µm. Variáveis limnológicas foram simultaneamente determinadas. A abundância larval correlacionou-se significativamente com oxigênio (positivamente) no verão, com a temperatura (positivamente) no inverno e com fósforo total e nitrogênio total (ambos negativamente) no inverno. Esperávamos um decréscimo da densidade em direção ao norte (gradiente latitudinal) e aumento em condições lênticas (reservatórios). Apesar de a densidade máxima ter sido encontrada próximo do ponto de introdução (La Plata River) valores similares também foram observados 2.000 km ao norte (rio Paraguai).

“…In 1991, golden mussel Limnoperna fortunei (Dunker 1857) was found while studying SAD in the Rı´o de la Plata estuary (Pastorino et al, 1993). This species soon started to rapidly disperse at a rate of 240 km.year x1 (Darrigran, 2002) and became a serious macrofouling organism (Darrigran, 2010;Darrigran and Damborenea, 2011), and its impact may become as significant as that of the invasive zebra mussel Dreissena polymorpha (Pallas 1771) in North America (Claudi and Mackie, 1994). Indeed, the invasive potential of L. fortunei is revealed by its sharing of a number of biological characteristics with D. polymorpha (Morton, 1977), including its freeswimming planktonic larvae (Darrigran et al, 2007), byssal filaments for attachment to hard substrates, high resistance to air exposure (Montalto and Ezcurra de Drago, 2003; and high reproductive potential (Darrigran et al, 2003).…”

-The golden mussel Limnoperna fortunei was introduced into Argentina in 1991 and has since been spreading through the Plata and Guaı´ba basins at a rate of 240 km.year x1 . To assess their ability to invade the Andean tributaries of the Plata Basin (Pilcomayo, Bermejo and Salado del Norte rivers), their current range was assessed and related to the abiotic parameters of sites where they were present and absent. These data were then compared with their known tolerances to identify possible barriers to invasion. Outputs suggested that three environmental parameters are barriers to invasion: salinity and river flow intermittence in different sectors of the rivers Pilcomayo and Salado del Norte, and concentration of suspended sediments in the Bermejo River and in the upper reaches of the Salado del Norte and Pilcomayo rivers. The importance of these findings is discussed in relation to using environmental data to infer the invasion possibilities and the utility of environmental data to better understand invasion patterns and processes.
