Environmental influences on the composition and structure of the freshwater mussels in shallow lakes in the Cuiabá River floodplain

Abstract: The maintenance of the freshwater mussels' community in lakes is determined by abiotic factors at the local scale and at regional scale by interspecific relations between the larvae of bivalves and fish host. Whereas the distribution pattern at local scale, our goal was to understand the abundance and community composition of bivalves and relate the environmental agents structuring this community. We sampled 20 lakes in the floodplain of the Cuiabá River using a standardized method of sampling. To evaluate the… Show more

“…Surveys of freshwater mussels in the Amazonas River basin did not record specimens of D. granosus in the Uraricoera and Branco rivers (Mansur and Valer 1992), Madeira and Aripuanã rivers (Pimpão 2007), Aripuanã River (Pimpão and Mansur 2009), and the confluence of the Negro and Solimões rivers . The species also was not not recorded in areas of the Pantanal region bordering the Amazon region (Serrano et al 1998;Colle and Callil 2012). All these surveys recorded other Diplodon species.…”

“…Identificamos três espécies de Gastropoda e quatro de Bivalvia e mesmo com uma coleta limitada espacialmente os registros obtidos foram representativos. Em lagoas da região Colle & Callil (2012) identificaram cinco espécies de gastrópodes e nove de bivalves, dentre as 28 espécies de moluscos límnicos (23 bivalves e 5 gastrópodes) atribuídas para o Pantanal de Mato Grosso (Junk et al,2006a;Junk et al,2006b). Considerando toda a Bacia do Alto Rio Paraguai (BAP), esses dados estão incompletos, sobretudo para bivalves, haja vista que Wantzen et al (2011) em uma revisão de literatura, listaram 28 espécies em tributários e lagoas da planície alagável do Pantanal que compõem a BAP.…”

“…No período seco, é o tamanho do corpo de água que determina o quanto cada ambiente consegue manter sua estrutura de habitats e desse modo, as populações que os habitam (Junk et al, 2006a;Silva-Filho, 2004;Stenert & Maltchik, 2007;Wantzen et al, 2011). Contudo, efetivamente, as diferenças na composição de moluscos são relacionadas ao hábito, características das espécies e estrutura de habitat (Maltchik et al, 2010a;Colle & Callil, 2012). Uma maior riqueza de bivalves foi encontrada nas poças de Corixo, possivelmente porque este ambiente é estruturalmente mais diverso, e por ser lótico, apresenta maior fluxo de .33 vetores de dispersão (peixes); contudo pela pouca profundidade foi insubsistente para manter as populações durante a seca.…”

“…In Brazil, it is difficult to determine whether species are threatened, because of the scarcity of information about the structure and distribution of the communities (Mansur et al 2003). Furthermore, most studies on communities inhabiting running waters are concentrated in the southeastern (e.g., Giovanelli et al 2005, Vidigal et al 2005, França et al 2007) and southern (e.g., Pereira et al 2001, Pfeifer & Pitoni 2003, Rangel e Souza et al 2008 regions, and are relatively rare in other parts of Brazil (Midwest region: Martins- Silva & Barros 2001, Colle & Callil 2012North region: Jesus et al 2007, Pimpão & Mansur 2009). In the semiarid Northeast region of Brazil, such studies are practically nonexistent , Souza et al 2010, and malacological research deals, in general, with lentic settings such as reservoirs, "açudes" (small reservoirs) and small waterbodies, focusing on vector species of human diseases or on invasive species (e.g, Abílio et al 2006, Santos & Eskinazi-Sant'Anna 2010, Souto et al 2011.…”
