| description | Temporal and spatial variations of transparency, temperature, pH, conductivity, and plankton are described for the subtropical oligohaline Lobos pond (Buenos Aires province, Argentina) and its main tributary during a complete annual cycle. Morphometric and pluviometric data, as well as a brief revision of previous studies of pampasic ponds are given. Our results show that salts in the pond derived from its tributary, and that rainfall is the key factor in modifying the ecological conditions in the pond. 181 planktonic species, including several ticoplanctonic ones, were recorded; many of these are halophilous organisms. Discrimination was made between the species that dwell in the pond only, and those which have lotic origins. Numerically the phytoplankton is dominated by blue-green algae, while the green algae and diatoms are the most diversified groups. Copepods and rotifers are the most abundant zooplankters; while highest numbers of species were yielded by the latter and the ciliates. |

Se describe la variación espacial y temporal de la transparencia, la temperatura, el pH, la conductividad y el plancton en la laguna subtropical oligohalina Lobos (provincia de Buenos Aires, Argentina) y su afluente principal a lo largo de un ciclo anual. Se presentan datos morfométricos, de precipitaciones y una corta revisión de los estudios sobre lagunas pampásicas. Se determina que las sales son aportadas a la laguna por su afluente, que la amplitud de la variación de su concentración salina es mayor que la registrada previamente y que las lluvias son el principal factor de alteración de las condiciones ecológicas de la laguna. Dentro del plancton, incluyendo al ticoplancton, se registran 181 especies, muchas de las cuales son halófilas. Se discriminan las especies que son autóctonas de la laguna de aquellas que pueden tener origen lótico. El fitoplancton se encuentra dominado por las cianofitas en cantidad y por las clorofitas y dlatomeas en variedad, y el zooplancton por la abundancia de copépodos y rotíferos y la variedad de rotíferos y ciliados.
