Figure 3: Examples of NH4+ uptake experiments in the laboratory.

From: Nitrogen and phosphorus uptake rates of different species from a coral reef community after a nutrient pulse

Figure 3

Decrease of NH4+ concentrations in the incubation water due to NH4+ uptake by (a,b) the macroalga Dictyota menstrualis (from 5 m depth) and (c,d) the benthic cyanobacterium Lyngbya majuscula (from 20 m depth). The species were incubated at low (left column) and at high (right column) initial NH4+ concentrations. Error bars represent s.d. of the mean (n = 9). NH4+ uptake experiments of the other species are shown in Supplementary Figs S1 and S2.
