Microzooplankton : Ciliate Grazing Rates

Summary

Abstract: 

In conjunction with the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, lakes were monitored for microzooplankton by a team based out of the University of Nottingham (led by Johanna Laybourn-Parry). This dataset shows grazing rates of ciliates feeding on cryptophytes between November 1997 and January 1998. The sample for this micro dataset was gathered at the Lake Fryxell.

Date Range: 

Saturday, November 1, 1997 to Thursday, January 1, 1998
