| Sumario: | 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). |
