Ocorrência do molusco asiático Corbicula fluminea (Müller, 1774) (Bivalvia, Corbiculidae) no baixo rio Negro, Amazônia central

Abstract

Resumo o rio negro é um dos maiores afluentes do rio amazonas, mas poucos moluscos foram registrados até o momento para aquele rio, representados apenas por gastrópodes. Foi registrada a presença do molusco bivalve exótico Corbicula fluminea na margem esquerda do baixo rio negro, no lago do tupé e no Catalão -margem direita do rio negro, todas localidades no município de Manaus, Brasil. o registro foi realizado por meio da coleta de conchas e espécimes vivos. É o primeiro registro de C. fluminea para o estado do amazonas e amazônia central.

Bivalvia, Cyrenidae, Corbicula fluminea (Müller, 1774): new record, density, and population structure in the Teles Pires River, northern Mato Grosso, Brazil

“…No found C. fluminea were found during the rainy season. This absence was also observed in the Negro River (Pimpão and Martins 2008); Cuiabá River (Massoli and Callil 2012) and in the Lake Constance (Werner and Rothaupt 2008). The rainwater increases the flow of the rivers and individuals can be carried with the surface sediments, or else, they can bury to protect themselves from strong current.…”

First record and range extension of Corbicula fluminea (Müller, 1774) (Bivalvia, Cyrenidae) in the Chapada dos Veadeiros region, Goiás, Brazil

“…Since the first Brazilian record in the 1970s (Veitenheimer-Mendes 1981), C. fluminea has been reported in all major river basins. There are records of this species in the Upper Tocantins River in the state of Goiás (Thiengo et al 2005) (Tocantins-Araguaia Basin); Tietê River in São Paulo (Suriani et al 2007), Paranoá Lake in Distrito Federal (Rodrigues et al 2007), Paranapanema River in São Paulo (Jorcin and Nogueira 2008), Araguari River in Minas Gerais (Maroneze et al 2011), Toropi River in Rio Grande do Sul (Sá et al 2013), Ivinhema River in Mato Grosso do Sul (Isaac et al 2014), Upper Paraná River in Paraná (Ragonha et al 2014), Jundiaí--Mirim River in São Paulo (Beghelli et al 2014) (Paraná River Basin); São Francisco River in Sergipe (Santana et al 2013) (São Francisco River Basin); Guandu River in Rio de Janeiro (Miyahira et al 2017) (Paraíba do Sul River Basin); Cuiabá River in Mato Grosso (Fernandez et al 2014) (Paraguai River Basin); and Negro River, Amazonas (Pimpão and Martins 2008) (Amazonas River Basin).…”

First occurrence of the exotic Asian clam Corbicula fluminea (Muller, 1774) in the Jundiaí-Mirim River Basin, SP, Brazil

“…It was introduced in Brazil in about 1970 (Veitenheimer-Mendes, 1981). It has been registered in many Brazilian States: Amazonia (Pimpão and Martins, 2008), Brasília (Rodrigues et al, 2007), Goiás (Thiengo et al, 2005), Minas Gerais (Maroneze et al, 2011), Paraná (Bagatini et al, 2005, Rio Grande do Sul (Martins et al, 2006) and São Paulo (Vianna and Avelar, 2010). In São Paulo State, species records are mainly concentrated in the Midwest region and near the borders with Minas Gerais (FAPESP, 2014).…”
