“…The dominance of the Chydoridae family was also reported by other researchers (Elmoor-Loureiro, 2007b;Elmoor-Loureiro and Mendonça-Galvão, 2008;Maia-Barbosa et al, 2008;Sousa and Elmoor-Loureiro, 2008;Castilho-Noll et al, 2010;Soares and Elmoor-Loureiro, 2011) (Table 4). This fact may be related to the peculiar characteristics of organisms in this family that have a thicker shell, spines and appendages specialized in grasping substrates, allowing greater mobility and success in the littoral lake areas.…”

-The aim of this study was to describe the composition and structure of cladocerans of littoral areas with and without macrophytes from a temporary shallow pond in the Caatinga of Pernambuco state (Brazil). Samples were taken between June 2011 and August 2012. The sampling of cladocerans and environmental variables was performed at four fixed points, using a plankton net (45 μm) and a multiparameter probe. Twenty-two cladoceran species were recorded, with two new occurrences for Pernambuco state: Chydorus cf. brevilabris and Macrothrix superaculeata. The species richness of non-planktonic cladocerans (16) was higher than that of planktonic ones (4). The mean density was 186.7 ± 273.6 ind. L -1 . Macrothrix elegans, Diaphanosoma spinulosum and Ephemeroporus hybridus were the most abundant. The fluctuation index of the main species showed greater instability during the driest months or greater rainfall, a pattern not observed for the environmental data. However, the pond did not show limnological and cladoceran structure differences between the dry and rainy seasons and between the areas with and without macrophytes. With the exception of temperature and rainfall, the structure and richness of cladocerans was not related to the fluctuation of the other variables. Warmer months had higher densities and richness of cladocerans. On the other hand, months of greatest rainfall had lower richness, especially for the Chydoridae family. Although this Caatinga pond is maintained exclusively by rainwater, the richness of cladocerans is high when compared to other tropical and subtropical ecosystems. These results suggest that rainfall and temperature exert greater control on the dynamics of cladocerans in the Caatinga's temporary shallow ponds, and demonstrate the importance of these ecosystems to biodiversity in the semiarid region.

“…In another study in shallow wetlands in the Brazilian Cerrado, Sousa and Elmoor-Loureiro (2008) found 11 species in the richest site and four in the poorest site in an inventory of Cladocera fauna conducted in the Emas National Park, also in Goia´s state. Their results are quite similar to the ones reported by this study the BNP and FIC (Tables 4 and 5), and it is noticeable that the number of species is very similar.…”

“…In case of Cladocera, which the most species live in association with aquatic macrophytes (Forro´et al, 2008), the information is only preliminary (Elmoor-Loureiro, 2007;Sousa and Elmoor-Loureiro, 2008). These studies presented the species richness; however, there was no attempt to assess the sampling effort because no systematized methods was used for data collection.…”

-The wetlands found in the Brazilian Cerrado are poorly studied environments regarding ecological aspects. Assessing the diversity of aquatic invertebrates in wetlands is a challenging task, since there are no standard sampling methods that minimize the spatial effects caused by macrophytes. The aim of this study was to evaluate the efficiency of a new sampling method for assessing Cladocera richness in macrophyte-rich wetlands of Brazilian Cerrado. In six wetlands, one transect was established which corresponded to a gradient of depth or change in aquatic vegetation. Samples containing cladocerans were collected using plankton net dragged among aquatic vegetation in the dry and rainy seasons. The species accumulation curves using non-parametric estimators and the overestimation of richness were used to determine the sampling efficiency. The species accumulation curves showed different asymptotic trends regarding the season and wetland studied. Especially in the rainy season, an asymptotic trend was not observed in two of the wetlands studied, which may reflect the influence of seasonality on Cladocera assemblage. Nevertheless, the overestimation of species richness showed that the method of sampling was able to find more than 60% of the estimated species richness, regardless of season or wetland studied. These results indicate that the method employed for sampling Cladocera in the Cerrado wetlands can be considered adequate.
