IN responding to the request of the editor for a review of the investigations into cycles involving alternating modes of reproduction, it has seemed wise to limit the field to the rotifers, aphids and cladocera. These three groups possess a cycle fundamentally alike. A unified discussion of them is therefore possible, even though a unified explanation has not yet been attained. Moreover, to tre...

A cladistic analysis of the genera of the Macrothricidae (Crustacea, Cladocera, Radopoda) was performed based on 36 morphological characters, and including 15 terminal taxa (three as outgroups). The single tree obtained from this analysis supported the monophyly of Macrothricidae and Macrothricinae. The group called as “non-Macrothricinae” was indicated as paraphyletic. Neothricidae was also no...

This study presents a review of scientiometric data about freshwater microcrustaceans (Copepoda, Ostracoda, Branchiopoda: Cladocera, Anostraca, Notostraca and Conchostraca) in Brazil from 1990-2014. This review is based on 179 papers published across four databases, using the following keywords in the search: microcrustaceans, Copepoda, Cyclopoida, Calanoida, Harpacticoida, Ergasilidae, Daphnii...

Twenty one genera of zooplankton were studied based on year investigation which 3 belonged to Cladocera (19.22%), 5 Copepoda (36.13%) 12 Rotifera (44.59%) and 1 Ostracoda (0.06%).

This study examined the cladoceran assemblages in three oxbow lakes of the Taquari River floodplain, near the transition between the plateau and the plain. We sought to answer the following questions: does the Taquari River function as a geographical barrier or dispersal corridor for Cladocera? Can different degrees of connection induce different structures in the assemblages in each lake? Clad...

This study was carried out to determine seasonal variation and zooplankton community structure in Karataş Lake, Southern Turkey. Zooplankton samples were collected seasonally between 2002 and 2003 in two stations using a zooplankton net of 55-µm mesh size. A total of 42 taxa were identified, including 19 taxa (45.2 %) Rotifera, 16 taxa (38.1 %) Cladocera, and 7 taxa (16.7 %). Copepoda. Among th...
