New records of two cladoceran species (Branchiopoda: Anomopoda) from Northeastern Brazil: the importance of studies in temporary ponds

Abstract Temporary ponds are heterogeneous aquatic environments, in which hydrodynamics and richness of macrophytes may increase the diversity of zooplankton and other invertebrate communities. Cladocerans are common residents of these ecosystems, showing great variability of forms. During a faunistic survey in temporary ponds under the influence of riparian vegetation, in the Camucim Forest Protected Area, Pernambuco Endemism Center, Brazil, the cladocerans Moina dumonti Kotov, Elías-Gutiérrez and Granado-Ramírez, 2005 and Chydorus nitidulus (Sars, 1901) were found. These are their first records in the Oriental Northeast Atlantic hydrographic region, and the second record of M. dumonti in Brazil. The present study raises Cladocera species richness in Pernambuco State to 73 and also 16 in the Pernambuco Endemism Center.
