Abstract

. The pelagic / anoxic hypolimnion population of Spirostomum teres was investigated as a part of the long-term ciliates’ monitoring (2003–2016) in an oligo- to mesotrophic monomictic hyposaline crater lake Alchichica (Puebla / Veracruz, Mexico), including an analysis of picoplankton (both heterotrophic, HPP and autotrophic, APP) and inorganic compounds of nitrogen (ammonium, nitrite, nitrate), phos phorus (dissolved reactive phosphorus, DRP) and silicon. Additionally, detailed studies of the ciliate vertical distribution and feeding activity measured upon fluorescently labelled APP (picocyanobacteria) tawhatcheeana ) could be of higher importance that previously supposed. Additionally, a use of ingested and retained photosynthetic prokaryotes is hypothesized.

圆螺旋体:一个以光合作用微生物为食的缺氧-低阴离子种群的长期研究

．作为长期监测的一部分(2003-2016)，在墨西哥普埃布拉/ Veracruz的Alchichica低营养-中营养单一低盐火山口湖中，研究了螺旋体(Spirostomum teres)的中水/缺氧低磷种群，包括微浮游生物(异养，HPP和自养，APP)和无机化合物氮(铵，亚硝酸盐，硝酸盐)，磷(溶解活性磷，DRP)和硅。此外，荧光标记APP (picocyanobacteria tawhatcheana)测量纤毛虫垂直分布和摄食活动的详细研究可能比以前认为的更重要。此外，摄取和保留的光合作用原核生物的使用是假设的。

期刊介绍： Acta Protozoologica - International Journal on Protistology - is a quarterly journal that publishes current and comprehensive, experimental, and theoretical contributions across the breadth of protistology, and cell biology of Eukaryote microorganisms including: behaviour, biochemistry and molecular biology, development, ecology, genetics, parasitology, physiology, photobiology, systematics and phylogeny, and ultrastructure. It publishes original research reports, critical reviews of current research written by invited experts in the field, short communications, book reviews, and letters to the Editor.
