Earlier studies of testate amoebae in Amazonian Sphagnum ombrotrophic bogs revealed 47 taxa (Swindles et al., 2014, 2016) and provided the description of a new species, namely Arcella peruviana (Reczuga et al., 2015).
Through the photosynthesis, ombrotrophic bog plants take C from carbon dioxide (C[O.sub.2]) and thereby sequester C as the excess of vegetation production over decay (Chambers et al.

In view of the large rain shadow thrown by the Andean mountains in the Southern Cone, as they contain the perturbations originating in the Southern Pacific (see Figure 1), it is therefore only natural to find a greater extension of peatlands in Chilean territory, particularly in ombrotrophic territories or promoted by rain water.

Concentrations of Cd, Br, Sr, and Zn in peat were up to an order of magnitude higher than in ombrotrophic (air-fed) bogs elsewhere, whereas Hg and Cu concentrations were similar to those in other peats, suggesting relatively low levels of Hg and Cu in the guano.
Shotyk (1988) also include hydrological parameters to distinguish peat bogs fed exclusively by precipitation water (rain and/or snow), called ombrotrophic bogs and those influenced by water from the external limits of the basin are called minerotrophic bogs.

(2006a) reported that the amount of [Cu.sup.2+] bound to the HA fraction extracted from an ombrotrophic peat bog was greater than the amount bound to the FA fraction, and only at the highest concentration of metal ion did the amount of [Cu.sup.2+] sorbed by both fractions became equal.
