Fig. 4

The metabolic rates (in mmol m−2 meadow area d−1) for plant- and epiphyte-mediated processes under ambient (A) and vent (B) pH conditions, based on a 12:12 h light and dark cycle, are depicted in the upper portion of each panel. Data distribution is shown in a box plot format, with the center line denoting the median value (50th percentile), the box encapsulating the interquartile range (25th to 75th percentiles), and whiskers indicating the 5th and 95th percentiles. Nitrification was not detectable (n.d.) at the ambient site. The lower portion of each panel employs arrow size to convey the relative differences in N cycling processes. Additionally, the % contribution of N2 fixation to the estimated N demand of the plant, as well as relevant taxa in the microbial community for each N cycling process, are provided for further context.
