“…The first registers of golden mussel in the reservoir cascades of this region of La Plata were reported in the beginning of 2000's. Between 2001 and 2004 its presence was detected in the reservoirs of Ilha Solteira, Jupiá, Porto Primavera and Itaipu, upper Paraná River (Zanella and Marenda, 2002;Mansur et al, 2004;Von Ruckert et al, 2004 andAvelar et al, 2004); during 2006 in the reservoirs of Canoas I, Canoas II and Capivara, Paranapanema River (Garcia et al, 2009;Rocha et al, 2011);during 2007/2008 in Tibagi and Iguaçu Rivers (Pestana et al, 2010); during 2004 in the Tietê River (already mentioned) (Pareschi et al, 2008). In the most northern large rivers of the basin, Paranaíba and Grande Rivers, we did not register the species presence.…”

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). A primeira hipótese foi refutada. A segunda hipótese foi parcialmente aceita. Abu...

Applying the theories of Materials Science and Engineering to describe the composition and hierarchy of microstructures that comprise biological systems could help the search for new materials and results in a deeper insight into evolutionary processes. The layered microstructure that makes up the freshwater bivalve Limnoperna fortunei shell, an invasive specie in Brazil, was investigated utilizing SEM and AFM for the determination of the morphology and organization of the layers; and XRD was used to determine the crystalline phases of the calcium carbonate (CaCO 3 ) present in the shell. The presence of the polymorphs calcite and aragonite were confirmed and the calcite is present only on the external side of the shell. The shell of L. fortunei is composed of two layers of aragonite with distinct microstructures (the aragonite prismatic layer and the aragonite sheet nacreous layer) and the periostracum (a protein layer that covers and protects the ceramic part of the shell). A new morphology of the calcite layer was found, below the periostracum, without defined form, albeit crystalline.

“…As well, the correlation degree between the variables was evaluated to identify a possible collinearity among them. In this way, pH / dissolved oxygen / chlorophyll a / turbidity / conductivity and calcium were considered as directly important to L. fortunei survival (Morton 1975, Ricciardi 1998, Sylvester et al 2004, Karatayev et al 2007, Pareschi et al 2008. The spatial variation of the physical-chemical properties of water, chlorophyll a concentrations and the L. fortunei density were assessed by applying a one-way ANOVA and the Tukeys method a posteriori or, a Kruskal-Wallis test for non-normal distribution cases with post-hoc comparisons of mean ranks of all pairs of group (Siegel & Castellan 1988).…”

The introduction of the golden mussel, Limnoperna fortunei (Dunker, 1857) in South America was related to the discharge of ballast water, with its first record in 1991 in the La Plata River estuary. Since then, the species is spreading throughout the continent, with several economic and ecological negative consequences. Aim: To model, in the headwaters of Parana River, the spatial distribution of L. fortunei and to understand the determinants of the current pattern of species distribution and the risk of invasion of areas not yet colonized. Methods: The ecological niche of L. fortunei was modeled using the algorithm MAXENT (Maximum Entropy Method) combined with records of occurrence of the bivalve, limnological data and the shear force measured by the index Hack (SL). The evaluation of the performance of different models was based on AUC (Area Under the Curve).The analysis of each variable's contribution to the responses of the models was made based on the Jackknife test, available in the Maxent program. The models were validated with real absence data collected between 2006 and 2007. Based on the limnological characterization of the area and on outputs of the models, this analysis sought to understand the contributing aspects to the current and potential spatial distribution and to verify the risk of invasion of environments not yet colonized by the species. Results/Conclusion: The limnological characterization showed that the ecological requirements for the species as, pH, calcium, oxygen and chlorophyll a, were appropriate in both the connected stretches, invaded and noninvaded. Turbidity showed significant spatial differences which proved to be higher in environments with higher levels of Hack (SL), i.e. higher energy fluvial. In addition, the algorithm showed the importance of hydrodynamical aspects expressed by Hack index (SL) to the spatial distribution of species, since the models with the best performances were those that considered the Hack index (SL) as one of the environmental layers of the mussel's niche. All models indicated a high risk of invasion into the reservoir of São Simão. Keywords: invasive species, biological invasions, niche modeling, Maxent, ecological requirements.
