<meta content="The autotrophic ciliate Mesodinium rubrum
Lohmann was observed during winter and spring in
saline lakes ranging in salinity from 2 to 78&amp; in the
Vestfold Hills, Antarctica. The ciliate remained active
during winter, and contained chlorophyll even though
the level of light available for photosynthesis was
minimal. No evidence of encystment as a means of
survival during winter was observed. A seasonal study
in one of the lakes, Ace Lake, revealed that M. rubrum
was present throughout the year at abundances
ranging from 1]104 to 3.5]105 cells l~1. During the
winter period, when little light penetrated the lakeÃƒÂ•s
ice cover, cells were most common immediately under
the ice at 2 m, where cell numbers were typically
8]104 cells l~1." name="eprints.abstract" />

Lohmann was observed during winter and spring in&#13;
saline lakes ranging in salinity from 2 to 78&amp; in the&#13;
Vestfold Hills, Antarctica. The ciliate remained active&#13;
during winter, and contained chlorophyll even though&#13;
the level of light available for photosynthesis was&#13;
minimal. No evidence of encystment as a means of&#13;
survival during winter was observed. A seasonal study&#13;
in one of the lakes, Ace Lake, revealed that M. rubrum&#13;
was present throughout the year at abundances&#13;
ranging from 1]104 to 3.5]105 cells l~1. During the&#13;
winter period, when little light penetrated the lakeÃƒÂ•s&#13;
ice cover, cells were most common immediately under&#13;
the ice at 2 m, where cell numbers were typically&#13;
8]104 cells l~1.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The original publication is available at www.springerlink.com</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">Mesodinium rubrum, Vestfold Hills, Antarctica, lakes, biogeography, winter</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/270706.html">270000 Biological Sciences &gt; 270700 Ecology and Evolution &gt; 270706 Life Histories (incl.
