| Knowledge of the life cycle of zooplankton species can provide information for a better understanding of the role of each species in the community and basic data for secondary production investigations. In this study, some life-cycle traits were measured for Scapholeberis armata freyi Dumont & Pensaert, 1983 (Cladocera, Daphnidae), maintained under controlled conditions in laboratory cultures. Experiments were carried out in incubators at a temperature of 23.0 ºC, photoperiod of 12 hours light/dark, and food supply (algal suspension of the chlorophycean Pseudokirchneriela subcapitata at 10(5) cells.mL-1 and mixed suspension of yeast, and fish ration added per organism, at equal proportions) that were kept constant. Observations were made once or... |

| The Chydorus and Pseudochydorus genera are widely distributed around the world. Some species of Chydorus are among the commonest anomopods and Pseudochydorus globosus, the only species of the genus, is believed cosmopolitan. This study was part of the project " Zooplanktonic biodiversity and state of degradation of continental water ecosystems in São Paulo State" , itself a part of the FAPESP/BIOTA Program - The Virtual Institute of Biodiversity (www.biotasp.org.br), the aim being to make an inventory and analyze the distribution of species of the genera Chydorus and Pseudochydorus in São Paulo State, Brazil. In total, 373 samples were collected from 223 water bodies in the Water Resources Management Units of São Paulo State, between 9/9/1999 and... |
