Figure 3: Abiotic and biotic influence on REE variability in pore-water.
From: Ecosystem Composition Controls the Fate of Rare Earth Elements during Incipient Soil Genesis
(A) Total denudation of L-, M- and H-REE in pore water collected over the 20-month experiment for following treatments: C, control; B, bacteria; BG, bacteria-grass; BGM, bacteria-grass-mycorrhiza. (B) Rock normalized sample means of L-, M- and H-REE in pore-water (g in water : g in rock, expressed as % per column) as a function of rock and ecosystem composition. Error bars represent one standard error (SE) of the mean. Tetrad groups (Y excluded) are separated by vertical lines. Numbers inset represent tetrad magnitude values, with M- and W-type curve values above and below 1, respectively. Values close to unity (no tetrad effect) are not displayed. Number colors correspond to treatment colors.
