1 Introduction
Many inventories of the zooplankton diversity of the rivers of the Amazon basin are available, especially for the principal, white- and black-water tributaries. The principal studies have focused on the marginal várzea lakes of the Amazon and Negro floodplains (see Robertson and Hardy, 1984Robertson, BA. and Hardy, ER., 1984.

on the lower Nhamundá River. Given this, the present study provides a checklist of the zooplankton of two fluvial lakes and four sites in the main channel of the middle Xingu, a clear-water river in the southeastern Amazon basin.
2 Material and Methods
2.1 Study area
The present study was conducted along a 180 km stretch of the middle Xingu River in Pará, in the eastern Brazilian Amazon basin (Figure 1). This region is characterized by numerous waterfalls and rapids, as well as extensive areas of alluvial rainforest (Camargo et al., 2005Camargo, M., Giarrizzo, T. and Isaac, V., 2005. Review of the Geographic distribution of fish fauna of the Xingu River basin, Brazil. Ecotropica, vol. 10, p. 123-147.).
The climate of the study area is of Köppen’s A type, with variants Aw and Am (Critchfield, 1968CRITCHFIELD, HJ., 1968. General climatology. Nova Delhi: Prentice-Hall. 420 p.). Mean annual temperatures in the study area oscillate between 17.5 °C and 24.5 °C, with relative humidity of 84-86%. Mean annual precipitation varies from 2066.8 mm to 2379.4 mm (Camargo et al., 2005Camargo, M., Giarrizzo, T. and Isaac, V., 2005. Review of the Geographic distribution of fish fauna of the Xingu River basin, Brazil. Ecotropica, vol. 10, p. 123-147.).
Six environments were monitored in the present study. Two were located in lakes on river islands (Ilha Grande and Pimentel) and the other four (Boa Esperança, Arroz Cru, Caitucá and CNEC) in the main Xingu River. Ilha Grande lake (3°34’47”S, 52°23’42”W) is semi-circular, with a depth of 0.5-2.5 m, and a total area of approximately 15,612 m2. The bed of this lake is covered in slimy silt, sand, and leaf litter derived from the island’s dense alluvial rainforest, and high concentrations of phytoplankton were associated with the reduced Secchi transparency (0.8-1.1 m) and high levels of dissolved oxygen (DO: 5.0-7.5 mg.l-1), and the slightly acid water (pH = 5.9-6.7) with low conductivity, of 30 uS.cm-1 (Estupiñan and Camargo, 2008Estupiñan, R. and Camargo, M., 2008. Ecologia da paisagem natural. In CAMARGO, M. and GHILHARDI, R. (Eds.). Entre a terra, as águas e os pescadores do médio rio Xingu: uma abordagem ecológica. Belém: Maurício Camargo. 329 p.). The second lake, Pimentel (3°25’46” S, 52º24’4” W), located on the river’s Great Bend, is elliptical in shape, with a mean surface area of 1570 m2, depths of between 0.8 and 3.0 m, with low pH (5.0-5.4) and Secchi transparency (0.90 0.98 m), and low DO (2 mg.L-1) and reduced levels of chlorophyll, which determine its low levels of primary productivity (Estupiñan and Camargo, 2008Estupiñan, R. and Camargo, M., 2008. Ecologia da paisagem natural. In CAMARGO, M. and GHILHARDI, R. (Eds.). Entre a terra, as águas e os pescadores do médio rio Xingu: uma abordagem ecológica. Belém: Maurício Camargo. 329 p.). During the rainy season, the forest is flooded by the creeks that drain the area surrounding the lakes.
On the river margin, Boa Esperança (3°34’46” S, 52°24’42” W) is located in the vicinity of Ilha Grande (Figure 1), while Arroz Cru (3°34’46” S, 52°24’42” W) is near Pimentel Island. The Caitucá marginal site (3°33’47” S, 51°24’42” W) is located in the large river bend (Cotubelo) deflection (Estupinãn and Camargo, 2008Estupiñan, R. and Camargo, M., 2008. Ecologia da paisagem natural. In CAMARGO, M. and GHILHARDI, R. (Eds.). Entre a terra, as águas e os pescadores do médio rio Xingu: uma abordagem ecológica. Belém: Maurício Camargo. 329 p.). The CNEC site (3°16’16” S, 51°24’42” W) is upstream from the larger waterfalls before the lower Xingu River. The pH of the river varied from 6.4 to 7.6 and conductivity was low (20-31 uS.cm-1) which, together with the DO concentrations of 7.1-8.6 mg.L-1 indicate highly that the water is highly oxygenated (Estupinãn and Camargo, 2008Estupiñan, R. and Camargo, M., 2008. Ecologia da paisagem natural. In CAMARGO, M. and GHILHARDI, R. (Eds.). Entre a terra, as águas e os pescadores do médio rio Xingu: uma abordagem ecológica. Belém: Maurício Camargo. 329 p.).
Every two months between August 2006 and June 2007, four zooplankton samples were collected at the surface and middle depths of the two lakes (Ilha Grande, Pimentel), while two angular sub-surface samples were collected from four stretches of the main channel of the Xingu River (Figure 1). The samples were collected with a 40 μ mesh plankton net equipped with a digital flowmeter in the river and by filtering 400 liters of water into a bucket in the lakes. The specimens collected were fixed and preserved in 4% formalin. Sorting and identification of specimens were carried out with a Wild-Leitz stereo-zoom dissecting microscope. Identification of the specimens was based on Cipólli and Carvalho (1973)Cipólli, MN. and Carvalho, MAJ., 1973.

3 Results
This study recorded a total of 175 taxa, comprising 141 rotifers (80.6%), 20 cladocerans (11.4%), five copepods (2.9%), and nine (5.1%) bottom-dwelling protozoans, gastrotrichs and insects (Tables 1 and 2). In general, the fluvial habitats were the most diverse. The richness of taxa varied from 70 in Ilha Grande lake to 124 in the rapids. Despite being much smaller than Ilha Grande lake, Pimentel lake had a relatively high richness, with a total of 114 taxa.
Zooplankton species recorded in different environments of the Middle Xingu River (2006-2007).
The Rotifera was the most diverse group, accounting for approximately 80% of total taxon richness in each of the study environments (Table 1). Much less diverse were the Cladocera, with around 8% of the taxa, and the Calanoida and Copepoda, each with approximately 2% (Table 1).
Most of the rotifers (19.86%) belonged to the family Lecanidae. Brachionus calyciflorus, Pallas, 1866; Testudinela tridentata Smirnov, 1931; Lecane murrayi (Hauer, 1965), and Ilyocryptus spinifer (Herrich, 1884) all occurred exclusively in the main channel, whereas Brachionus mirabilis (Daday, 1897), Gastropus stylifer Imhof, 1891; Trichocerca rousseleti (Voigt, 1901), and Macrothrix superculeata Baird, 1843 were found only in the lakes.
4 Discussion
The rotifers were the most diverse group of zooplankton recorded in the present study on the middle Xingu River in the southeastern Amazon basin, with approximately 80% of the organisms found in each study environment. A similar pattern has been recorded in the aquatic systems of white- (77%) and black-water (40%) rivers in the Amazon basin (Table 3), as well as other systems (see Green, 1972Green, J., 1972.

.
The distinct composition of the zooplankton found in the two lakes studied here reflect their different limnological characteristics, such as the much larger surface area of the Ilha Grande lake in comparison with Pimentel, which in turn is subject to a considerable input of organic matter from the surrounding forest, which also shelters the lake from the sun. Pimentel lake is also connected more extensively to the main river, with the water being filtered by the surrounding forest before draining into the lake (Estupiñan and Camargo, 2008Estupiñan, R. and Camargo, M., 2008. Ecologia da paisagem natural. In CAMARGO, M. and GHILHARDI, R. (Eds.). Entre a terra, as águas e os pescadores do médio rio Xingu: uma abordagem ecológica. Belém: Maurício Camargo. 329 p.). The considerable phytoplankton biomass and high primary productivity recorded in Ilha Grande lake (Costa et al., 2008Costa, V., Costa, S. and Camargo, M., 2008. Os produtores primários: o fitoplâncton e o Periliton. In CAMARGO, M. and GHILHARDI, R. (Eds.). Entre a terra, as águas e os pescadores do médio rio Xingu: uma abordagem ecológica. Belém: Maurício Camargo. 329 p.) may have determined the low zooplankton richness recorded in this lake. The higher zooplankton diversity recorded in Pimentel lake appears to have been related to specific characteristics of this environment, such as the low current velocity, given that reproductive populations of planktonic organisms are restricted to the slow-flowing lower reaches of these areas (Ward, 1994Ward, JV., 1994. The structure and dynamics of lotic ecosystems. In MARGALEF, R. (Ed.). Limnology now: a paradigm of planetary problems. Amsterdam: Elsevier Science BV. 218 p.).
