Testate Amoebae (Rhizopodea-Sarcodina) from Zooplankton of the High Paran� River Floodplain, State of Mato Grosso do Sul, Brazil: I. Families Arcellidae and Centropyxidae

“…The species was more abundant in lentic than in lotic environments, but it has never shown high density. Some records of this species in Brazil were formerly made: Manguinhos, State of Rio de Janeiro (Prowazek 1910;Cunha 1913 et al 1990, 1992).…”

“…It was a common species in our samples and more abundant in lakes than in rivers. In Brazil the species was recorded in Manguinhos, State of Rio de Janeiro (Prowazek 1910;Cunha 1913); in the lakes of the Suia Missu River basin, State of Mato Grosso (Green 1975) and in plankton samples of São Francisco River basin, State of Minas Gerais (Dabés 1995).…”

“…The first records of testate amoebae in Brazil were done by Ehrenberg (1841), Prowazek (1910) and Cunha (1913), the most important papers on zooplank- ton which recorded this group of organisms are those published by Prowazek (1910), Green (1975), Neumann-Leitão & Nogueira-Paranhos (1987), Barbieri & Godinho-Orlandi (1989), Rolla et al (1990Rolla et al ( , 1992 and Lansac-Tôha et al (1992, 1993.…”

Diversity of freshwater dinoflagellates in the State of Paraná, southern Brazil, with taxonomic and distributional notes

“…The first reference to a dinoflagellate collected in Brazil was from Rodrigo de Freitas Lagoon, State of Rio de Janeiro, made by Möbius (1889), describing Peridinium tabulatum f. brasilianum Möbius ('brasiliana'; reinterpreted as Bysmatrum subsalsum (Ostenfeld) Faust et Steidinger by Popovský & Pfiester 1990). In the first half of the 20 th century, studies on protozoofauna (dinoflagellates were then considered from a zoological viewpoint) identified some dinoflagellate species (Daday 1905;Prowazek 1910;Cunha 1913;Kleerekoper 1939). With a gap of almost 30 years, new records of this group were made in southeastern (Bicudo & Bicudo 1967;Bicudo & Skvortzov 1968;1970;Bicudo & Ventrice 1968) and northern Brazil (Uherkovich & Schmidt 1974;Uherkovich 1976;1981;Uherkovich & Rai 1979;Uherkovich & Franken 1980).…”
