Summary

Description
English: Testate amoebae common in various types of peatlands along the bog-rich fen gradient

(1) Archerella flavum(Archer 1877) Loeblich et Tappan 1961, (2) Arcella catinus Penard 1890, (3) Hyalosphenia papilio Leidy 1874, (4)Assulina muscorum Greeff 1888, (5) Euglypha strigosa Ehrenberg 1848, (6) Centropyxis aerophila Deflandre 1929, (7) Lesquereusia spiralis Ehrenberg 1840, (8) Cyphoderia cf. ampulla Ehrenberg 1840, (9) Difflugia bacillariarum Perty 1849, (10) Paraquadrula irregularis Wallich 1863, (11) Microchlamys patella (Claparède et Lachmann 1859) Cockerell 1911, (12) Pyxidicula patens Claparède et Lachman, 1858.

The distribution of species along the poor-rich gradient defines the bog-fen habitat that is mainly determined by hydrological dynamics, especially higher supplies of groundwater and nutrient input in the rich end of the gradient. Other variables influencing testate amoebae also vary between the peatland type, e.g., the poor end of the gradient is characterized by a low pH whereas the rich end of the gradient possesses a higher pH and high ground water Ca and Mg concentrations. White scale on each of the photos equals 10 μm.
