| ciliates and their picophytoplankton-feeding activity in a high-altitude warm-monomictic saline lake. | the impact of feeding on autotrophic picoplankton (app) on the ciliate composition of the assemblage was surveyed monthly along a depth gradient in the maar crater, athalassohaline, warm monomictic lake alchichica (puebla, mexico) from june 2003 to december 2005. numbers of app were evaluated from their autofluorescence. dapi staining and the fluorescently labeled bacteria technique were employed to count ciliates and estimate their feeding rates. a total of 38 taxa of ciliates have been identif ... | 2008 | 17931843 |
