Diversity and structure of microcrustacean assemblages (Cladocera and Copepoda) and limnological variability in perennial and intermittent pools in a semi-arid region, Bahia, Brazil Iheringia, Sér. Zool.
Simões,Nadson R.; Ribeiro,Sylvia M. M. S.; Sonoda,Sérgio L..
Temporary wetlands undergo recurrent drought due to the scarcity of water, which disrupts the hydrological connectivity with adjacent aquatic systems. However, some environments retain water for longer periods, allowing greater persistence of the community. The current study evaluated differences in the microcrustacean assemblages and limnological variability between perennial and intermittent pools in a semi-arid region of Brazil. The abiotic features (water temperature, pH, total alkalinity, electrical conductivity and depth) of intermittent pools were affected more than perennial pools due to loss of water volume. This may have contributed to a higher average richness and diversity index in some intermittent pools and differences in the structure of the...

Turbelários límnicos (Platyhelminthes) em ecossistemas de arroz irrigado da Planície Costeira do sul do Brasil Biota Neotropica
Vara,Dioneia Conceição da; Leal-Zanchet,Ana Maria.
Turbellarians occur in a variety of wetlands, being also abundant in temporary water bodies. Several turbellarians are top predators in their microhabitats, many of them feeding on zooplankton. However, they are seldom taken into account in biodiversity studies. Information on turbellarian diversity in Brazilian freshwater ecosystems mainly came from taxonomical studies. In southern Brazil, there are a high number of wetlands, most of them represented by rice fields. Despite their impact on natural areas, these managed ecosystems can play an important role in freshwater biodiversity conservation. The aim of the present work was to report on an inventory done in irrigated rice fields of three areas of the Coastal Plain of southern Brazil, viz. Cachoeirinha,...
