“…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.

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.

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).

“…Damborenea and Penchaszadeh (2006) reported that the species manifested a high flexibility during its reproductive cycle and that its dispersion was favored by human activity (Darrigran and Ezcurra de Drago, 2000;Manzur et al, 2003;Avelar et al, 2004;Brugnoli et al, 2005;Belz et al, 2005). This invasive species exhibits a great plasticity with respect to environmental variables, and this characteristic has been confirmed from the results of the analysis of correlation by Pearson, which data indicate special relationships to the physicochemical parameters examined in this present study.…”

The Island of Martin Garcia is located in the Upper Río de la Plata, to the south of mouth the Uruguay River. The aim of the present study was to analyse the biodiversity of the island freshwater mollusks and their relationships to environmental variables. Twelve sampling sites were selected, five were along the littoral section of the island and seven were Inland ponds. Seven major environmental variables were measured: water and air temperature, percentage of oxygen saturation, dissolved oxygen, electrical conductivity, total dissolved solids and pH. Twenty-seven mollusk species were found, Antillorbis nordestensis, Biomphalaria tenagophila tenagophila, B. t. guaibensis, B. straminea, B. peregrina, Drepanotrema kermatoides, D. cimex, D. depressissimum, Chilina fluminea, C. rushii, C. megastoma, Uncancylus concentricus, Hebetancylus moricandi, Stenophysa marmorata, Heleobia piscium, H. parchappii, Potamolithus agapetus, P. buschii, P. lapidum, Pomacea canaliculata, P. megastoma, Asolene platae, Corbicula fluminea, Eupera platensis, Pisidium sterkianum, P. taraguyense and Limnoperna fortunei. UPGMA clustering of species based on their occurrence in different ecological conditions revealed two main species groups. The Canonical Correspondence Analysis suggests that the species distribution is related to the physico-chemical condition of water. Axis two of the ordination diagram displayed the approximately 95.6% of the correlation between species and environmental variables. Dissolved oxygen, conductivity, water temperature and pH showed the highest fluctuations during the sampling period. The species richness (S) showed relationships mainly with water temperature and conductivity. The biodiversity of the gastropods and bivalves from Martín García Island amounts to up to 26 species. Among the Gastropoda, the Planorbidae family made the most sizeable contribution. The Lithogliphidae P. agapetus (26.28%) and P. buschii (9.50%) showed the highest relative frequencies of occurrence within the littoral environments, while the Planorbidae D. cimex (23.83%) and D. kermatoides (11.59%) likewise did so in the inland ponds.Keywords: biodiversity, CCA, ecology, mollusks, Martín García Island.

Os rios do estado de São Paulo estão em processo contínuo de eutrofização, o que favorece frequentes florações de cianobactérias, prejuízos à qualidade da água para o consumo humano e riscos à biota aquática. O mexilhão dourado (Limnoperna fortunei) é uma espécie exótica invasora que pode ser vetor na transferência de toxinas de cianobactérias. O objetivo deste estudo foi avaliar a ocorrência de florações de cianobactérias no rio São José dos Dourados, suas toxinas produzidas e a possibilidade de ficotoxinas bioacumularem em Limnoperna fortunei. Foram detectadas, nas amostras, a dominância de cianobactérias tóxicas e cianotoxinas (microcistinas). Os resultados indicaram que L. fortunei acumularam microcistinas. As florações de cianobactérias nas águas do rio estudado indicaram prejuízo ao ambiente associado à eutrofização e aos riscos da presença das cianotoxinas à biota aquática.Palavras-chave: bioacumulação; cianobactéria; ficotoxinas; espécies exóticas; molusco; eutrofização. ABSTRACTCyanobacterias are natural components of the phytoplankton community, but they are often associated with eutrophic waters. Rivers in the state of São Paulo are in a continuous process of eutrophication, which favors the frequent cyanobacteria blooms in these environments, compromises the quality of the water for human consumption and promotes risks to the aquatic biota. The golden mussel (Limnoperna fortune) is an invasive alien species that can be a vector in the transfer of cyanobacterial toxins. The aim of this study was to evaluate the cyanobacteria blooms occurrence in São José dos Dourados River, their cyanotoxins and the possibility of phycotoxins bioaccumulating in the Limnoperna fortunei. Toxic cyanobacterias and cyanotoxins (microcystins) were detected in the samples. The results indicated that L. fortunei accumulated microcystins. The cyanobacterial blooms in the water of the studied river indicated a damage to the environment associated with eutrophication and risks of cyanotoxins presence to the aquatic biota.
