A key to marine species of Vannella (Sarcodina: Gymnamoebia), with descriptions of new species
TLDR
All six species studied with the electron microscope have the characteristic surface structure found also in freshwater members of the genus Vannella Bovee, which is probably their main food in nature.Abstract:
A key to all nine described marine species of naked lobose amoebae classified in the genus Vannella Bovee , 1965, is presented. All six species studied with the electron microscope have the characteristic surface structure found also in freshwater members of the genus. The key includes five species isolated from British waters, including three new species; a fourth new species is from the Persian Gulf area. Generic identification of Vannella , even in mixed material, can be made readily with the electron microscope, which is sometimes necessary for positive distinction from Platyamoeba . Further identification to species is a light-microscopical procedure. Members of this genus are cultured on bacteria, which are probably their main food in nature.read more

Heterotrophic Amoebae, Flagellates and Heliozoa from the Tvärminne Area, Gulf of Finland, in 1988–1990
TL;DR: Ninety-five taxa of heterotrophic protists (amoebae, flagellates and heliozoa) were encountered in wild material and cultures established from marine samples from Tvarminne Archipelago, Gulf of Finland.

Barcoding amoebae: comparison of SSU, ITS and COI genes as tools for molecular identification of naked lobose amoebae.
TL;DR: COI may be a good candidate for DNA barcoding of amoebae, but further studies are necessary to confirm the accurateness of the COI gene as a barcode in other gymnamoEBae, and to understand the taxonomic meaning of COI variations.

Phylogeny, evolution, and taxonomy of vannellid amoebae.
TL;DR: A new genus Ripella is established, with distinct morphology and sequence signatures for Vannella platypodia and morphologically similar species that form a clearly separate clade, very distant from other Vannellidae.

TL;DR: Fifty per cent of the species identified in this study are principally associated with detritus (marine snow), and the majority of free-living suspension feeders the authors identify are choanoflagellates, which represents five different trophic types of organisms, defined by habitat and prey.

An illustrated survey of gymnamoebae isolated from anaerobic sediments of the niva bay (the sound) (Rhizopoda, Lobosea)
TL;DR: Twelve species of amoebae were found in cultures established from samples of mats of white sulphur bacteria from the Niva Bay, and only one species, Vannella peregrina Smirnov & Fenchel, 1996 is strictly anaerobic.

Trophic interactions in soils as they affect energy and nutrient dynamics. IV. Flows of metabolic and biomass carbon
TL;DR: Over the 24-day experiment, respiration was significantly higher in the microcosms containing the bacterial grazers and the amoebae allocated more carbon to tissue production and correspondingly less to CO2, with partitioning of available carbon by the microfauna varied considerably.

TL;DR: After 24 days the nematode populations in the treatments without carbon additions were dominated by resistant dauer larvae indicating the unavailability of food, and the adult component of the population was still increasing at the end of the 24-day experiment.
