Název v původním jazyce

Ciliates and their picophytoplankton-feeding activity in a high altitude warm-monomictic saline lake

Popis výsledku v původním jazyce

The impact of feeding on autotrophic picoplankton (APP) on the ciliate assemblage composition was surveyed in the maar crater, athalassohaline, warm monomictic Lake Alchichica, Mexico. Fluorescently Labeled Bacteria technique was employed to estimate feeding rates. Peritrichs followed by minute spirotrichs (Halteria grandinella) often numerically dominated and emerged as the most efficient APP feeders. A maximum was observed at the end of the mixing period, during the development of diatoms (Cyclotellaalchichicana), the cyanobacterial bloom (Nodularia sp.) and its decay. Mixotrophic Euplotes cf. daidaleos was an important feeder near the oxycline. Scuticociliates, Cyclidium glaucoma, Uronema nigricans and an anaerobic cf. Isocyclidium globossum dominated in the hypolimnion and did not ingest APP. For the majority of the ciliates, APP were not an important food, being selected by a few species mostly in microaerobic conditions.
