Corrigendum for Saiz et al. 2012, Global Change Biology 18: 1489–1780, doi: 10.1111/j.1365-2486.2012.02657.

The original article already published is: Global Change Biology (2012) 18, 1670–1683, doi: 10.1111/j.1365-2486.2012.02657.x

In our paper that was published online on 2 March 2012 and then published in issue 5, GCB Volume 18, the Table 2 that was incorporated in the article is incorrect. The below table is the correct Table 2.

Table 2. Relative abundance of main minerals present in the soil (<2 mm) extracted from x-ray diffraction (XRD) analysis for the different sites across the transect. Absolute differences in Fe and Al contents (mg g−1) between x-ray fluorescence (XRF) and (XRD) analyses are also shown to assess the presence of amorphous or poorly crystalline mineral phases and test the accuracy of the XRD-Rietveld-determined elemental contents

  1. Other minerals present in rather small concentrations include those bearing Ti, Ca, and Na (i.e. rutile, plagioclase, etc.) which are not shown here. Amorphous minerals not detected by XRD are also not shown. Mineral contents determined by the XRD-Rietveld approach was converted to elemental composition (i.e. Fe and Al) using factors derived from the ideal chemical formulae of minerals shown above.
