Descripción
Temporary ponds represent special environments that are inhabited by organisms adapted to changing environmental conditions. Ciliates are able to survive complete loss of water in these transient habitats through cyst formation. Nevertheless, ciliates from the Neotropical region in general have been poorly studied through the use of modern techniques. The main goal of this study is to describe the ciliates developing in dried sediments of a temporary pond from the Buenos Aires Province, Argentina through samplings that were performed during the period 2003-2005. Soil samples were obtained during drought phases and rewetted in laboratory, in order to establish raw and enriched cultures. Ciliates were then studied both in vivo and after  impregnation with protargol. In this study, we present four new records for Argentina (Gonostomum affine (Stein, 1859) Sterki, 1878, Stylonychia bifaria (Stokes, 1887) Berger, 1999, Pleurotricha lanceolata (Ehrenberg, 1835) Stein, 1859, Meseres  corlissi Petz and Foissner, 1992), one more for South America (Blepharisma americanum (Suzuki, 1954) Hirshfield, Isquith and Bhandary, 1965), and two for the Neotropical Realm (Gonostomum strenuum (Engelmann, 1862) Sterki, 1878, Stylonychia lemnae Ammermann and Schlegel, 1983).
Los cuerpos de agua temporarios son ambientes particulares que se encuentran habitados por organismos adaptados a condiciones fl uctuantes. Los ciliados son capaces de sobrevivir a la pérdida completa de agua del ambiente gracias a la formación de estructuras de resistencia. Por otra parte, los ciliados de la región Neotropical han sido poco investigados con técnicas modernas. El objetivo de este estudio es referir los ciliados que se desarrollaron a partir de los sedimentos secos de una charca temporaria de la provincia de Buenos Aires, Argentina, en la que se realizaron muestreos durante el período 2003-2005. Las muestras de suelo fueron obtenidas durante las fases de sequía y luego resuspendidas en el laboratorio para realizar cultivos naturales y enriquecidos. Los ciliados fueron estudiados in vivo y luego de la impregnación argéntica con protargol. En este trabajo se presentan 4 nuevos registros de especies para la fauna de ciliados de la Argentina (Gonostomum affi ne (Stein, 1859) Sterki, 1878, Stylonychia bifaria (Stokes, 1887) Berger, 1999, Pleurotricha lanceolata (Ehrenberg, 1835) Stein, 1859, Meseres corlissi Petz and Foissner, 1992), 1 para América del Sur (Blepharisma americanum (Suzuki, 1954) Hirshfi eld, Isquith and Bhandary, 1965) y 2 para la región Neotropical (Gonostomum strenuum (Engelmann, 1862) Sterki, 1878, Stylonychia lemnae Ammermann and Schlegel, 1983).
