| Sumario: | Studies about ostracods in shallow lakes are very scarce in the Province of La Pampa, thus the objective of this work is to contribute to the knowledge of the species present in lentic environments, studying the distribution, abundance, and specific associations of ostracods. The samples come from four shallow lakes of the Pampean Region, Province of La Pampa, Argentina. Sampling was performed along transects perpendicular to the shore. Five genera represented by six species of benthic ostracods were identified. Heterocypris similis was present in all sampled water bodies, but was dominant in the Monte de Caldén (LCM) and Don Tomás (LDT) lagoons. Cypridopsis vidua was very abundant in the LCM. The species Chlamydotheca incisa and Potamocypris unicaudata were only recorded in the Ojo de Agua Lagoon (LCS). C. incisa is recorded for the first time in the province, and P. unicaudata in Argentina. The qualitative and quantitative variations of the ostracod assemblages can be related to topography, sedimentology, vegetation and salinity variations. The results of this study are important in the interpretation of the environments recorded during the Quaternary, since these species are also registered as fossils. |
