Trophic interactions within the plankton of the lowland River Meuse (Belgium) were measured in spring and summer 2001. Consumption of bacteria by protozoa was measured by monitoring the disappearance of H-thymidine-labelled bacteria. Metazooplankton bacterivory was assessed using 0.5-μm fluorescent microparticles (FMPs), and predation of metazooplankton on ciliates was measured using natural ci...

The present results are the last part of a series of experiments conducted in this laboratory on metabolism of major individual rumen ciliate protozoa species and their combinations in sheep. These species were inoculated into the rumen of fauna-free (FF) sheep to study digestibility of dietary fibre and duodenal flow of N. Sixteen rumen- and duodenum-cannulated FF sheep were divided into four ...

During a survey in 2015, an impressive assemblage of organisms was found hypersaline pond the Messolonghi saltworks. The salinity ranged between 50 and 180 ppt, that were fell into categories Cyanobacteria (17 species), Chlorophytes (4 Diatoms (23 Dinoflagellates (1 Protozoa (40 Rotifers (8 Copepods Artemia sp., one nematode Alternaria sp. (Fungi). Fabrea salina most prominent protist among all...
