First record of the occurrence of Ceratium furcoides (Levander) Langhans (Dinophyceae) in the Upper Paraná River Floodplain (PR/MS), Brazil.

First record of the occurrence of Ceratium furcoides (Levander) Langhans 1925, an invasive species in the hydroelectricity power plant Furnas Reservoir, MG, Brazil.

Occurrence of Ceratium furcoides (Levander) Langhans 1925 bloom at the Billings Reservoir, São Paulo State, Brazil.

An unusual bloom of Ceratium furcoides is reported for a station of the Taquacetuba compartment of the Billings Reservoir. The appearance of this bloom is attributed to the mixing and turbulence of the water column that removed Ceratium cysts from the surface of the sediment and promoted conditions for the growth of this species in the region of mixing. Cold fronts approaching the Billings Rese...

First record of a bloom of the invasive species Ceratium furcoides (Levander) Langhans 1925 in Rio Grande do Sul state, Brazil.

Ceratium Schrank is dinoflagellate genus commonly found in marine environments, and considered invasive in continental waters (Silva et al., 2012). Species of this genus are able to develop blooms due to their mobility and resistance to sedimentation, to the occupation of the surface layer and optimised use of resources such as light and nutrients (Donagh et al., 2005). Even though its blooms a...

Cladocera fauna composition in a river-lagoon system of the Upper Paraná River floodplain, with a new record for Brazil.

Cladocera communities were studied in lotic and lentic environments of the Upper Paraná River floodplain, State of Mato Grosso do Sul, Brazil. A total of 63 species of Cladocera were identified in 108 samples. Of these, 24 species are considered new records for that floodplain, and one is a new record for Brazil. Chydoridae was the most representative family with 19 genera and 39 species.

New record of planktonic cladoceran to the upper Paraná River, Brazil: Bosmina huaroensis Delachaux, 1918.

In this paper we register the first occurrence of Bosmina huaroensis Delachaux, 1918 in the upper Paraná River basin, which is probably the first record to Brazil. Illustrations and an updated description of the species are given.
