The present study provides a species list of freshwater mussels from Catalão, the meeting of the Solimões and Negro rivers, in state of Amazonas, northern Brazil. Expeditions to collect molluscs were carried out between 2004 and 2006, during high and low water seasons. Three hundred and thirty-one bivalve shells, 25 valves, and 57 live specimens of four families and 10 species were identified. A single exotic species, Corbicula fluminea, represented over half the collected shells. All bivalve shells were photographed and registered at the mollusc collection of the Instituto Nacional de Pesquisas da Amazônia (INPA), Manaus.

The present study provides a species list of fish from the Marmelos River Area – BX044 in the states of Amazonas and Rondônia in northern Brazil. During a Rapid Ecological Assessment (REA) performed in October and November of 2003, 133 fish species from six orders and 24 families were recorded. The most diverse families were Characidae (47 species), Cichlidae (15 species), Loricariidae (12 species) and Pimelodidae (7 species). 23 fish species were common to the entire river basin and 4 were endemic to the aquatic system studied.

Bivalve Shells

Bivalve shells can potentially alter the structure of aquatic benthic communities. However, little is known about the effect that different shell morphologies have on their associated fauna. This study aimed to understand how empty shells, from four different freshwater bivalve species, affect macrozoobenthic communities, using the River Minho (Iberian Peninsula) as a study area. Three native (Anodonta anatina, Potomida littoralis, Unio delphinus) and one non-indigenous (Corbicula fluminea) species were used for this research. Comparisons among species and between scenarios (i.e. before and after invasion by C. fluminea) were performed. Our results suggest that macrozoobenthic community structure did not vary among treatments, with the exception of species richness, which was higher on shells of native species. Furthermore, little difference was detected when comparing scenarios with and without C. fluminea shells, despite dissimilarities in size and morphology between species. The empty shells of C. fluminea partially (in terms of density and biomass, but not in species richness) replaced the role of empty shells of native species as a physical substratum for the associated macrozoobenthic community.

Abstract Southern Amazonia potentially harbors a wide diversity of aquatic macrophyte species because of its diverse wetland habitats and location in the Amazon-Cerrado transition zone, the two largest biogeographic domains in South America. We inventoried the taxonomic diversity of aquatic macrophytes in the region, including endemism, habitats, species life forms, and floristic comparisons with other Brazilian regions. We found a high number of species of aquatic macrophytes for the southern Amazon region, comparable to extensive inventories in larger areas in southern, northeastern, and northern regions of Brazil. We recorded 688 species of aquatic macrophytes in 299 genera and 95 families, of which 66 species are new records, 89 endemic, and 5 exclusive to Brazilian Amazonia. We present new records of aquatic macrophyte species, together with their degree of endemism and occurrence restricted to the region. The macrophyte species list of southern Amazonia showed 60% similarity to inventories in the Xingu basin and in northern Brazil. This high diversity of aquatic macrophytes in the Southern Amazonia, with endemic species and others with restricted ranges, emphasizes the importance of conserving wetlands and vegetation types where they grow in the region.
