“…The variations in the densities of larval stages of L. fortunei throughout the year and in all sampled sites were not related only to higher temperature values, cited as the main factor limiting larval development of the species (Kimura & Sekiguchi, 1996;Cataldo et al, 2005;Darrigran et al, 2007). Our results agree with Oliveira et al (2011) and Spaccesi (2013), and suggest that the temperature per se is not able to explain the population dynamic of L. fortunei neither the periods of spawns.…”

“…High temperatures seems to affect L. fortunei reproduction (Boltovskoy et al, 2009), but also accelerate L. fortunei development. Experimental studies have shown that the time between spawning and the second last larval stage (pediveliger) can be reduced from 480 hours to 265 hours with an increase of 8 °C in the water temperature (Cataldo et al, 2005). Additionally, seasonal changes have a major influence in flooding areas such as the upper Paraná River floodplain (Agostinho et al, 2004), where major temporal variations in physical, chemical and biological conditions can be attributed to the flood pulse effects (Thomaz et al, 2007), a fundamental phenomenon to keep the integrity of these ecosystems (Junk et al, 1989;Neiff, 1990).…”

Aim:To verify the temporal dynamics of Limnoperna fortunei larval stages and to identify the main environmental variables driving the larval density patterns in an area highly impacted by reservoirs. Methods: Samplings were performed quarterly, from February to December 2014, in 10 transects along to the Paraná River main channel. For each sample site, 100 L of water were filtered. The filtrated was fixed in alcohol 80%, and the larval stages were counted and classified under the optical microscope. Concomitant to biological collections we took some of the main water variables. We performed a Redundancy Analysis (RDA) in order to summarize the variations in densities of larval stages in relation to the main physical and chemical water variables. Results: We found a total of 200,590 L. fortunei larvae, in which 83.6% were identified as the initial stages. The most abundant months in L. fortunei larvae were December and February. The first two axes of RDA sum up 96% of the total data variation, and the most significant environmental variables explaining variations in larval densities were: water temperature, total nitrogen, electrical conductivity, phosphate, dissolved oxygen, depth and ammoniac ion. The warmer months were influenced by the major values of water temperature and depth, besides the higher densities of all larval stages. Conclusions: Our results indicate that L. fortunei reproduction follows a general pattern throughout the upper Paraná River floodplain, what seems to occur mainly between February and December. Thus, we suggest that measures for the L. fortunei control should be done during low-density periods (i.e., April to August), when the water level is low, and consequently, the dispersion of this species might be limited.Keywords: area of environmental preservation; propagule pressure; golden mussel; reproduction.Resumo: Objetivo: Verificar a dinâmica temporal dos estágios larvais de Limnoperna fortunei, e identificar as variáveis ambientais direcionadoras desses padrões, em uma área altamente impactada pela construção de reservatórios.

“…The first stage was correlated with temperature and the other stages with the high concentration of dissolved oxygen, conductivity and pH. Studies by Cataldo et al (2005), Darrigran et al (2007), Kimura and Sekiguchi (1996), Cataldo and Boltovskoy (2000) and Oliveira et al (2011) suggest that temperature is fundamental for the reproduction, while water oxygenation is important to the development of individuals.…”

“…Although the latter represents a small fraction of the diet of L. fortunei, phytoplankton is responsible for supplying more than 90% of the energy demand required by the specie at certain seasons (Sylvester et al, 2009). In addition to food resources, some abiotic factors seem to facilitate the establishment of L. fortunei, such as oxygen content and water temperature (Darrigran and Pastorino, 1995;Boltovskoy and Cataldo, 1999;Mansur et al, 2003;Cataldo et al, 2005;Darrigran et al, 2007;Pestana et al, 2010).…”

Limnoperna fortunei Dunker, 1857 is an Asian invasive freshwater bivalve. Although there need to contain their spread, studies about the biology of the larvae are scarce. We correlated the larval stages of L. fortunei with biotic factors such as phytoplankton and main abiotic variables in lotic environments of the Upper Paraná River floodplain. The four samples were taken quarterly during the year 2012. The Principal component analysis (PCA) showed only spatial differences, as did a Canonical Correspondence Analysis (CCA). High densities of larvae were recorded in all samples the Paraná River and Baía River only in December, especially those in their initial stage. In the biovolume of Class of algae, Bacillarophyceae showed the highest value, but Chlorophycea who was strongly correlated with the density of D-stage larvae. The large variety of phytoplankton, especially microplankton Chlorophyceae, high values of PO 4 , NH 4 and temperature were positively correlated with high densities of D-stage larvae. We conclude that high temperature, and food availability, indicated by phytoplankton community, favored the reproduction of L. fortunei and enhance the ability of specie dispersion due to the increase in the emission of propagules. Therefore, studies that address the biology of golden mussel larvae should be performed in order to prevent its spread.Keywords: invasive species, limnic bivalves, Paraná river, dispersal patterns, environmental filters.

“…Mussel larvae were found in greater density at station PR3 of the The use of the SL Index is applicable because the speed of the current may be a factor in the dispersion pattern of the planktonic larval stage of the mussels. Because Limnoperna free-living larvae take 10-20 days to reach the settling stage depending on current speed, they can be recorded hundreds and even thousands of kilometres downstream from their parent population (Cataldo et al, 2005).…”

Hydrological stress as a limiting factor of the invasion ofLimnoperna fortunei (Dunker, 1857) in the Upper Paraná River (Brazil)Estresse hidrológico como fator limitante para a invasão de Limnoperna fortunei (Dunker,1857) River, including the São Simão hydroelectric reservoir. Physicochemical characteristics of the water were analysed, and a Stream Length-Gradient Index calculated for the study area. Results: Adult mussels were easily found attached to the hulls of barges that travel on this stretch of the Paraná-Tietê waterway and on vessels that were docked in the harbours of grain exporters located in São Simão (GO). However, no larvae or adults were found near the harbours or upstream from them at the São Simão hydroelectric reservoir. The pH and concentration of calcium and dissolved oxygen values among lotic habitats and the reservoir were similar: DO values were close to 7 mg.L -1 , the average pH was near 7, average values of total Ca ranged between 4 and 6 mg.L -1 and the chlorophyll-a levels were not restrictive to the mussel. Conclusion: Physical and chemical water parameters show that habitats were suitable for establishment of the mussel. In addition to a low pressure of propagules, this paper proposes some hydrological variables, such as the energy of the fluvial stretches, expressed by the Stream Length-Gradient Index and changes in flow downstream of the dam as barriers to the establishment of the species, discouraging larval settlement, and decreasing survival and recruitment.Keywords: Limnoperna fortunei, invasive species, Paraná River watershed, golden mussel. 2012, vol. 24, no. 1, p. 64-82 http://dx.doi.org/10.1590/S2179-975X2012005000027Hydrological stress as a limiting..., o pH médio está em torno de 7, os valores médios de Ca total variam entre 4 e 6 mg.L -1 e os níveis de clorofila a não são restritivos para esta espécie de mexilhão. Conclusão: As variáveis físico-químicas da água indicam que os habitats são adequados para o estabelecimento da espécie. Além de uma baixa pressão de propágulos, este trabalho propõe algumas variáveis hidrológicas, tais como, a energia dos trechos fluviais e mudanças da vazão a jusante da barragem, como barreiras para o estabelecimento da espécie, uma vez que estes aspectos podem desfavorecer a fixação e sobrevivência das larvas e diminuir o recrutamento.Palavras-chaves: Limnoperna fortunei, espécies invasoras, Bacia do rio Paraná, mexilhão dourado.
