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).
