During studies conducted from 1991 to 1994 in the Pantanal of Mato Grosso, the physical and chemical parameters of natural water bodies supporting populations of euglenophyte species were determined, and the data were used to discover the conditions under which the individual species actually live. The results show that there is considerable specific variability not only in the minima and maxima of the individual parameters at which each species occurred but also in the ranges, some species appearing only within a narrow spectrum of physical or chemical conditions and others being able to survive in the greatest variety of environments. Information on the temperature, pH, electrical conductivity, oxygen saturation, water hardness, and concentrations of calcium, cloride, iron, silicate, ammonium, nitrite, nitrate, and phosphate at which a total of 43 species survived is presented.
