Invasion process of Limnoperna fortunei (Bivalvia: Mytilidae): the case of Uruguay River and emissaries of the Esteros del Iberá Wetland, Argentina
Provedor de dados: 103
Autores: Darrigran,Gustavo; Damborenea,Cristina; Drago,Edmundo C.; Ezcurra de Drago,Inés; Paira,Aldo; Archuby,Fernando.
Limnoperna fortunei (Dunker, 1857), during its invasion process in South America, has caused severe impacts both on natural environments altering native biodiversity, ecosystem structure and function-, and on man-made structures causing economic looses. Twenty-one samples were taken from the right bank of the Uruguay River, from tributaries of the Uruguay and Paraná Rivers, the drainage of the Esteros del Ibera Wetland. Based on this fieldwork, the presence of larvae and adults of L. fortunei was determined. Also, through the comparison of environmental characteristic with the known tolerance limits for the species, the possibility of its establishment in environments not yet invaded was determined. Most of the sampling stations have features that allow...

Variation in the distribution of Corbicula species (Mollusca: Bivalvia: Corbiculidae) after 25 years of its introduction in the Río de la Plata, Argentina

ABSTRACT In 1981, Corbicula fluminea (Müller, 1774) and C. largillierti (Philippi, 1844) were recorded at the Río de la Plata River. During the 1980’s, C. largillierti was found on a continuous fringe in the shore of that river, while C. fluminea was only found North of Buenos Aires’ harbor. Ten years later, C. fluminea spread to Punta Indio, while C. largillierti remained restricted to tributary streams. The density and size frequency distribution of both species were compared with previous data from samples performed in the same area in 1985-1989. The aim of this research was to determine whether the densities of both species decreased; whether C. fluminea is still more abundant than C. largillierti; and whether the size frequency distributions indicate...

Primeiros dados quali-quantitativos do mexilhão-dourado, Limnoperna fortunei (Dunker), no Delta do Jacuí, no Lago Guaíba e na Laguna dos Patos, Rio Grande do Sul, Brasil e alguns aspectos de sua invasão no novo ambiente

At the end of 1998 and the beginning of 1999, the golden mussel Limnoperna fortunei (Dunker, 1857), Mytilidae, originating from Southeast Asia, was registered for the first time in the Guaíba Lake Basin, Rio Grande do Sul State, Brazil. Quantitative samples were taken since the first register and for two years at various localities in the Jacuí Delta, northern limit of Guaíba Lake, and in the south limit of the later where it empties into Patos Lagoon. Samplings in Patos Lagoon revealed the presence of L. fortunei in October 2000 at Arambaré (30º54'S, 51º30'W) and in January 2001 at São Lourenço do Sul (31º20'S, 51º58'W). Quantitative samplings on roots of water hyacinths Eichhornia azurea (Sw.) Kunth and E. crassipes (Mart.) Solms-Laubach, on rhizomes of...

Toxicity of neem's oil, a potential biocide against the invasive mussel Limnoperna fortunei (Dunker 1857)
Provedor de dados: 42
Autores: Pereyra,Patricio J.; Rossini,Gustavo B.; Darrigran,Gustavo.
The golden mussel Limnoperna fortunei (Dunker 1857) is one of the most distributed Nuisance Invasive Species (NIS) in South America, and a threat of great concern for the industry of the area. In this study, we carried out toxicity tests made with a Neem's oil solution with L. fortunei larvae and benthonic adults (7, 13 and 19 ± 1 mm). Tests with non-target species (Daphnia magna, Lactuca sativa and Cnesterodon decemmculatus) were also made with the aim to evaluate the potential toxicity of the Neem's solution in the environment. The LC100 of Neem's solution obtained for larvae was 500 µl/L, a value much higher than the one obtained for D. magna and C. decemmaculatus. Thus, we recommend that it should not be used in open waters. However, since the adults...

Assessment of gonadal follicle size in the invading bivalve Limnoperna fortunei (Mytilidae)
Provedor de dados: 47
Autores: Guimarey,Pilar; Darrigran,Gustavo; Damborenea,Cristina; Penchaszadeh,Pablo E.
Limnoperna fortunei is an invasive gonochoristic and byssate freshwater bivalve originary from Southeast Asia. It shows great adaptive-reproductive ability, so knowledge of the gonadal cycle is an important factor for the prevention and control of this bioinvasion. This species is highly damaging to natural and human environments. We analyzed the distribution and maturity state of reproductive follicles in the mantle of both male and females. Male results are not shown but, in general, they followed the same pattern as that of females. Routine histological techniques included serial longitudinal sections and transversal sections in three body regions (anterior, middle and psoterior). Oocytes with conspicuous nucleoli were measured on both types of sections...
