Recent ostracodes from the pampas, Buenos Aires, Argentina: Ecology and paleolimnological implications

Twenty non-marine ostracod species were collected from the pampas of Buenos Aires Province. Water parameters were analyzed in order to determine what environmental conditions each species prefers and which factor affects their occurrence. Studies suggest that most species prefer waters containing pa...
