A review of systematics, distribution and ecology of tropical freshwater zooplankton

102+ rotifer species (Rotifera: Monogononta) in Broa reservoir (SP., Brazil) on 26 August 1994, with the description of three new species

“…They occurred in proportions that are strikingly similar to those in some previous reports : here, they account for 28 .4, 18 .6 and 10.8% of the fauna, respectively, whereas and Segers & De Meester (1994) reported 28 .5% Lecane, 12 .6% Trichocerca and 11 .6% Lepadella for in Nige-,11 .9% Lepadella ocerca from Papua New Guinea . A predominance of Lecane in acid waters of the tropics has also been reported by Dussart et al (1984) .…”

The biogeography of littoral Lecane Rotifera

“…It had already been noticed that Lecane is dominant in terms of species diversity in tropical acid waters (Fernando, 1980 ;Dussart et al, 1984 ;, where over 40 taxa can be found in a single locality . The same holds true for Brachionus (Pejler, 1977b ;Dumont, 1983) and for the much less species-rich, but equally littoral Scaridiidae (Segers, 1995b) .…”

“…Also salinity (De Ridder, 1981 a;Green & Mengistou, 1991 ;, and pH (Harring & Myers, 1928 ;Dussart et al, 1984) are cited in this respect. Regarding littoral Rotifera, it may be rewarding to examine the possible impact of Ostracoda on the occurrence of Rotifera .…”

How many species of Cladocera are there?

“…Some recent reviews 191 (Dussart et al, 1984 ;Frey, 1987 ;Shiel & Williams, 1990 ;Dodson, 1991 ;Dumont, 1994) pay attention to breadth, not to the quality of the material studied, or they analyse only separate groups (e .g . the Chydoridae) .…”
