Ecology of free-living freshwater heterotrophic euglenoids: A summarizing review.

This review aims to compile sparse information on the ecology of freshwater heterotrophic euglenoids and synthesize the main phenomena and hypotheses from published results. Apparently, heterotrophic euglenoids play a very important role in the nutrient flow of water ecosystems and are irreplaceable heterotrophic contributors in benthic communities, as their total biomass is by far the largest among heterotrophic flagellates. Even though they are obviously a very crucial part of the diversity of freshwater heterotrophic protists, and likely the most represented (in terms of biovolume) group of heterotrophic flagellates, there have been only a few attempts to elucidate their ecological preferences, roles, niches, and importance.

Checklist of colourless euglenoids of the Czech Republic, with several taxonomic additions.

This study presents the results of a complex survey of freshwater heterotrophic euglenoids in the Czech Republic, including both literature data and own field surveys of 469 sites visited in the course of three years. The checklist includes 189 taxa in 28 genera: Anisonema (10), Astasia (26), Atraktomonas (1), Calycimonas (2), Chasmostoma (1), Dinematomonas (3), Distigma (8), Dylakosoma (1), Entosiphon (4), Euglena (1), Gyropaigne (1), Heteronema (19), Jenningsia (11), Khawkinea (1), Lepocinclis (1), Menoidium (7), Neometanema (3), Notosolenus (18), Petalomonas (40), Phacus (1), Ploeotia (2), Pseudoperanema (7), Rhabdomonas (5), Scytomonas (1), Sphenomonas (5), Teloprocta (1) Tropidocyphus (1), Urceolus (4), and 4 species of uncertain identity. In addition, a general description of habitat types in which the taxa were found and a review of the current taxonomy and nomenclature of included taxa are provided.
