Rotifers from a humic coastal lagoon of Rio de Janeiro State,Brazil

Abstract

A four-year study of species composition of the zooplankton community was conducted at Lagoa Comprida, a Brazilian coastal lagoon. Forty-two species of rotifers were recorded and illustrated. All rotifer species, except Lecane boettgeri Koste, 1986 and Macrochaetus kostei, José de Paggi, Branco &; Kozlowsky-Suzuki, 2000 José de Paggi, S, Branco, C WC and Kozlowsky-Suzuki, B. 2000. A new species of Macrochaetus (Rotifera, Trichotriidae) in a coastal lagoon of Rio de Janeiro State (Brazil). Stud Neotrop Fauna &; Environm, 35: 157–160.

Some factors, which probably favored the dominant richness and density of rotifers in the zooplankton community, are discussed.
