“…The operational pattern of TGR results in a shorter summer residence time, since the residence time is defined as the ratio of the reservoir volume to the inflow rate (STRAŠKRABA and TUNDISI, 1999). Simultaneously, large amounts of silt-laden water are brought by floods which are usually induced by summer monsoon precipitation (JIANG et al, 2007).…”

We investigated the macroinvertebrate community structure in Three-Gorges Reservoir during a three-year period after the reservoir became operational. Comparison with data of previous authors obtained before the damming showed that the benthic community changed drastically in the reservoir. Oligochaetes and chironomids dominate the present community. An apparent annual cycle in the benthic community (expressed as richness, density and community type) was found in the second year, lagging one year behind the annual cycle of transparency. After the second year, a Nais-Polypedilum community type, occurring in winter and spring with low inflow discharge and high transparency, was followed by a Limnodrilus community type that occurred in autumn and summer under contrasting conditions. Despite river regulation and damming, it appeared that macroinvertebrates in subtropical canyon-shaped reservoirs remained influenced by floods.

“…Littoral zones are intensively affected by the processes that take place in both pelagic regions and in land (Nogueira et al 1993), with a great importance for the management of water quality (Straskraba et al 1993). However, even though high diversity in these zones is frequently reported, the biology and the ecology of the littoral zooplankton are not well-known (Nogueira et al 2003, Maia-Barbosa et al 2008 what, according to Lemly & Dimmick (1982), can be attributed to the lack of efficient and standardized sampling methods.…”

Pelagic and littoral cladocerans (Crustacea, Anomopoda and Ctenopoda) from reservoirs of the Northwest of São Paulo State, Brazil

Abstract:There are few studies on the zooplankton from the northwestern region of São Paulo State, Brazil, compared to other regions of the State. Cladocerans are a very representative zooplankton group with high species diversity. Most of this diversity can be found at littoral zones of lakes and reservoirs, especially those occupied by macrophytes. This study was part of a thematic project FAPESP/BIOTA Program -The Virtual Institute of Biodiversity (www.biotasp.org.br), and its aim is to catalogue and analyze the distribution of cladoceran species (Crustacea, Anomopoda and Ctenopoda) in pelagic and littoral zones from small reservoirs in the northwest of the São Paulo State, in dry and rainy seasons. Zooplankton samplings were carried out in littoral and pelagic zone of 10 small shallow reservoirs (mean depth: 2.8 m) using a plankton 45 µm mesh net. Water physical and chemical parameters were also monitored with a multiparameter Horiba U10. pH and dissolved oxygen concentration were lower at rainy than dry seasons, indicating high decomposition rates of organic matter introduced from the rural environment, being the main factor contributing to reservoirs' eutrophication. Fifty eight cladocerans species were recorded, with four new occurrences for the São Paulo State. This high richness contrasts with the high devastation of the northwestern region in the State. During the two seasons, littoral zones presented higher cladoceran richness and diversity than pelagic zone. Littoral zones with higher macrophytes diversity also showed higher cladocerans richness and diversity than that with low macrophyte diversity. Littoral and pelagic zones comparisons emphasized the importance of studies on different regions of the aquatic environments, confirming the elevated richness in the littoral zone, as reported in previous works. This study revealed also the strong influence of the macrophyte community and the adjacent terrestrial environment, which is occupied by forest or agriculture. Resumo: A região noroeste paulista é uma das regiões com menor quantidade de dados sobre o zooplâncton, comparado a outras regiões do estado. Os Cladocera constituem um grupo bastante representativo do zooplâncton, apresentando elevada diversidade de espécies. A maior parte desta diversidade pode ser encontrada nas regiões litorâneas de lagos e reservatórios, especialmente aquelas ocupadas por muitas macrófitas. Como parte de um projeto temático mais amplo (Programa Biota-Fapesp -Instituto Virtual da Biodiversidade, www.biotasp.org. br), o presente trabalho tem o objetivo de caracterizar as comunidades de cladóceros (Crustacea, Anomopoda e Ctenopoda) pelágicos e litorâneos presentes em pequenos reservatórios na região noroeste do estado de São Paulo, nas estações seca e chuvosa. As amostragens foram realizadas tanto na zona litorânea quanto pelágica de 10 pequenos reservatórios rasos (média de 2,8 m), através de arrastos verticais com rede de plâncton de 45 µm de malha. Parâmetros físicos e químicos da água também foram avaliados utilizando...

“…Thus, a gradient would form along the longitudinal axis of the reservoir. A typical reservoir can be divided into three zones: riverine zone (backwater), transitional zone (between riverine and lacustrine zone), and lacustrine zone (STRASKRABA and TUNDISI, 1999;WETZEL, 2001). The different zones have different physical and chemical characteristics, while environmental gradients always lead to the difference of biotic assemblages (BAXTER, 1977;VELHO et al, 2001; MORENO-OSTOS et al, 2008,).…”

The longitudinal patterns of the macroinvertebrate community in the Xiangxi Bay of the Three Gorges Reservoir (TGR) were investigated during the second (2nd) and third (3rd) impoundment stages (October 2006-July 2010, to test the effects of increased water level fluctuations (WLF) on the macroinvertebrates. By comparing to the former reports of the first (1st) impoundment stage (inter-annual WLF 4 m), we found that oligochaetes dominated in three different stages in the Xiangxi Bay. However, the total abundance of macroinvertebrates showed a dramatical decline from the 1st to 2nd stage (interannual WLF 11 m), but changed slightly from the 2nd to 3rd stage (inter-annual WLF 30 m). This indicated that higher WLF in the 2nd stage had already greatly reduced the macroinvertebrates abundance, thereby the disturbance in the 3rd stage could only slightly affect the already reduced abundance. Three longitudinal zones (the mainstream zone, the lacustrine zone and the transitional zone) were found based on the macroinvertebrate density, biomass, and taxa richness, combined with the geographical location of each site. Significant differences in density and biomass of macroinvertebrate were found among different zones (P < 0.05), yet no significant difference was found in taxa richness (P > 0.05). Two-way indicator species analysis showed that the community type in most sites varied in different seasons from the 2nd stage, exhibiting a dynamic zonation pattern, which differed with the stable pattern of the 1st stage. This seasonal feature was coupled to the seasonal changes of the WLF. IntroductionDam construction is considered as a disturbance to the former ecosystem, or the formation of a new system, by causing a series of ecological changes (BAXTER, 1977). Impoundment after dam construction will lead to slowing down of the water velocity, increasing of the transparency, depletion of the dissolved oxygen and accumulation of nutrients (BAXTER, 1977;FRIEDL and WÜEST, 2002;YE et al., 2007). These abiotic impacts in turn have biologi- cal effects, by structuring influences on the diversity, density and the overall resilience of reservoir biota (FUREY et al., 2006;MCEWEN and BUTLER, 2010). Benthic macroinvertebrates are important in aquatic ecosystem and have widely been used as indicators of variations of environmental conditions (PHIPPS et al., 1995; PELLETIER et al., 2010). They are usually affected by the sediment properties caused by the water disturbance (MCEWEN and BUTLER, 2010), and other changes of water environment factors, e.g., algal blooms, which could influence the food resources of macroinvertebrates (LOPES et al., 2000;WHITE et al., 2005).Reservoirs formed by damming rivers always differ from natural lakes in the shape of their longitudinal profiles. Natural lakes are normally deepest in the central region, whereas reservoirs are almost always deepest just upstream from the dam. Thus, a gradient would form along the longitudinal axis of the reservoir. A typical reservoir can be divided into three zones...
